Ethereum centralization concerns

Apologies if this has been addressed elsewhere, or if the information I'm responding to here is out of date.
tldr: Are Ethereum (full, validating) nodes incentivized to vote no on gas limit increases that would lead to centralization?
I just read this old post, its follow up post, and this response post all discussing whether or not Ethereum will trend towards centralization over time. As far as I can tell, all of that long discussion really boils down to disagreements about this paragraph from Gustav's post:

As miners are incentivized to act in ways that maximize the value of the tokens they receive in each mined block, they are unlikely to vote for a blocksize increase that would break the network. If the author trusts Bitcoin miners to act in ways that maximize the value of their bitcoins (such as not censoring transactions, generally prioritizing txs by their fee and otherwise act in ways that are beneficial for the network) the author should trust Ethereum miners to only vote for block sizes that can be handled by reasonable hardware, as the decentralized verification done by full nodes underpins the security of the network.
StopAndDecrypt replies:
The network doesn’t break because validators drop off and peers are lost. The network functions with two datacenters. What breaks is decentralization. The connected nodes have no incentive to care about other less-connected nodes validation abilities.
Vitalik even agreed that [the number of full validating nodes] would shrink over time if the gas limits kept going up, and there’s nothing stopping that from happening. Right now miners are being altruistic, but what happens when mining doesn’t even exist? What happens when it’s just staking and the people doing it don’t care about other people’s blocks getting orphaned? Why would they keep the gas limit down? Remember they can manually adjust this, so why would they intentionally keep it low if they’re hyper-connected to each other and fully capable of processing that data? What happens when they start compounding their staking earnings, setting up more nodes, and gain more control of the network?
As block sizes increase, the number of full validating nodes decreases. Bitcoin solves this by simply saying block sizes never go up, period, and if that limits the amount of TPS the L1 layer can handle, so be it; just scale on L2. Ethereum's answer according to Vitalik is the gas price limits (and indirectly through that block size limits) that each individual minevalidator enforces. Implicit in this I believe is that sooner or later the block size limit has to stop growing (approximating the bitcoin approach), at least until hardware costs drop enough. This relies on an incentive mechanism in place to prevent validators from constantly increasing gas limits per block and letting the network trend towards centralization. Without such an incentive mechanism, I'd think each individual validator wouldn't necessarily care if increasing block sizes caused other validators to drop off the network, so long as they are able to keep up, which does indeed seem like it would eventually lead to a small number of powerful validators controlling the base layer.
Core issue and my actual question:
So I think the real question at the core of this disagreement is: in what cases would (full, validating) nodes reject a block due to it being too big (using too much gas)? What are the incentive mechanisms that keep individual validators aligned with the goal of keeping the core validator pool decentralized?
Please note I'm only talking about the centralization of fully validating nodes with the power to reject new blocks, light clients don't help, and sharding helps by a constant factor in the short term but doesn't address the fundamental long term trends. PoW vs PoS is orthogonal and doesn't really affect the issues being discussed here .

How DAO users can truly control their voting rights

How DAO users can truly control their voting rights
Aelf proposed a solution that gives the control of the voting rights back to users by classifying token permissions.
As of today, there are still few complete businesses. In addition to mining and building trading platforms, it is difficult to create a complete business model. Moreover, various trading platforms have gradually grown into enterprises with comprehensive products in the blockchain industry, including wallets, nodes, lending, mining pools, etc.
At the same time, cloud services can reduce the cost of building small exchanges, but they can also lead to big trading platforms monopolizing data. For example, some Internet companies provide free cloud services in order to collect more valuable data.
Currently, Ethereum, which has the richest DeFi ecosystem, is gradually upgrading to V2.0, and its consensus protocol will also be upgraded to PoS. Governance voting can be regarded as the most important feature in the PoS ecosystem.
This year, Yearn.Finance rose to sudden prominence. But due to the governance problem, its community members initiated a hard fork, resulting in YFII. Another DeFi project, YAM, had a unfixable rebase function error. The founding team apologized for the error and announced a ‘Migration Plan’, which will turn the project over to the community.
For a while, governance voting became all the rage. However, the increasingly bigger trading platforms have been criticized by users in governance voting. Is there a proper solution to handling the relationship between the trading platform and governance voting?

What will we lose when trading platforms monopolize the blockchain industry?

In June 2018, during the BP node election before the EOS mainnet launch, node voting began to have a crisis of confidence between token holders and the trading platform. it is widely believed that the top 20 holders of trading platform wallets held about 40% of all the EOS in circulation.
Since then, many trading platforms have enabled the “User Authorization” interface. EOS holders can authorize the token voting rights to the trading platform, who will vote on behalf of the users. The rule caused a backlash from users, forcing these trading platforms to change the rule immediately so that EOS holders could vote on their preferred BP nodes.
After the EOS BP node votes, whether the trading platform has the token voting right has been occasionally discussed, but fewhave noticed it.
Two years later, Justin Sun, founder of TRON, made a commercial acquisition of Steemit, a decentralized social networking platform. After the acquisition was announced, the Steemit community launched a soft fork to resist the project being controlled by TRON. However, Justin Sun voted with the support of trading platforms such as Binance, Huobi and Poloniex to prevent a soft fork.
After being questioned by users, Binance and Huobi said that they would no longer interfere in the voting of the Steemit community. However, hkdev 404 of the Steem community again reveived votes from Huobi accounts. It is said that nearly 40 million votes were cast during the incident, accounting for about 10% of the total circulation of STEEM tokens.
There is no doubt that when the trading platform monopolizes the industry, we will lose our voting right.
How do we defend our voting rights
The fact that the ownership of the tokens belongs to the holders is indisputable, but what about the voting rights of the tokens deposited on the trading platform? How can we defend our voting rights after trading platforms have monopolized the industry?

Trading Platform Model

Traditional centralized trading platforms will assign to each user a separate deposit address. After depositing, the depositedamount will be added into the cold wallet and hot wallet. When users want to withdraw their tokens, the trading platform will transfer the tokens out of the hot wallet. If there is insufficient balance in the hot wallet, then the tokens will be transferred from the cold wallet to the hot wallet, and then be withdrawn.
Under the traditional centralized trading platform model, once users transfer their tokens into a trading platform, it means thetoken ownership (including voting rights) is also transferred to that trading platform.
The aelf solution: classify token permissions and claim back voting rights
For the issue of “voting rights” between token holders and centralized trading platforms, aelf, a decentralized cloud computing blockchain network, has proposed a solution: to establish an aelf Centre Asset Management Contract on the chain. The contract can limit the funds entering the exchange and define different permissions to control the assets.
The main feature of the aelf Centre Asset Management Contract is to create the “Main Virtual Address of the Trading Platform”.
Each exchange has a main virtual address, which can only be used for transfer operation, but not for voting, trading and other operations. As a result, the exchange cannot misappropriate users’ assets for voting. At the same time, the assets of the primary virtual address are publicly available on the chain, which makes it more difficult for the exchange to misappropriate assets.
At the same time, the aelf Centre Asset Management Contract also has the function of “address definition”. The exchange can open different permissions to different addresses, such as opening different permissions according to the amount, transactions exceeding a certain amount can only be given the greenlight by using multiple signatures, and the assets can be frozen through the contract when the assets of the trading platform are stolen, etc.
For the users of the trading platform, the access of the trading platform to the aelf Center Asset Management Contract function will not undermine user experience. The virtual system address of the aelf Center Asset Management Contract will assign a virtual address to each user, which offers the same user experience as the traditional mode.
For the trading platform, each deposit address constructed by the virtual address system is generated by the algorithm and does not need to be carried out on the blockchain. This means that the trading platform does not need to manage a large number of private keys, and there is no risk that the private keys will be lost.
On the most important “voting rights” issue, the aelf Center Asset Management Contract will assign to each user a separate virtual address for voting:
Voting address = Hash (Exchange Main Address + Token + “VOTE”)
Voting process: the tokens are transferred from the main virtual address of the exchange to the special “voting address” for voting, and are then voted. After voting, the tokens are withdrawn from the voting address back to the main virtual address.
We can see that the aelf Centre Asset Management Contract proposed by aelf can improve the efficiency of the trading platform without affecting user experience. In addition, it solves the problem that users would lose their voting rights.
According to the data on Crypto Mode, the market value of PoS tokens has exceeded $33 billion without counting Ethereum. In the field of crypto, it is the biggest ecosystem next to Bitcoin. The most important function of PoS is vote staking. faced with bigtrading platforms, if the status quo continues, retail investors will gradually lose their “voting rights” that belong to them.

Comparison of Market Value of PoS tokens (Source: Crypto Mode)
The emergence of DAO offers an alternative to trading platforms who misappropriate users’ tokens, but it still can not change this situation. Of course, DAO will not die out. Small communities will still use DAO for community governance. The idea behind the design of aelf is to start from the underlying trading platform and solve this issue at the source. Whether the solution can work still takes time. However, as a member of the crypto industry, we should understand the importance of “voting rights”, and cannot allow the exchange to seize our rights at will.
Recently, aelf has also announced its DeFi plan, which includes a new blockchain 3.0 project with a large number of new technical features, such as cross chain function, virtual address and cloud services. Aelf also proposed a set of interoperability solutions with ERC-20 tokens. It can directly access the ETH ecosystem, allow ETH-based applications and wallets to directly access it, and maintain the interoperability with ETH. And aelf will provide a high-performance smart contract operation platform and cloud services that can support cross chain interaction. Users on major cloud servers can easily run aelf’s services and adjust the scale of cloud according to their own business needs.
The implementation of a slew of tools, cloud services and interoperability solutions developed by aelf means that centralized transactions can be directly connected to the aelf network, realizing one-click adaptation to the DeFi ecosystem. With aelf, CeFi and DeFi are able to learn from and complement each other.

Bitcoin's next 15 years : Year 2020–2035

2020 4Q

~ More companies follow in Microstrategy’s footsteps. Rumors of more corporate treasurers investing in BTC in boardrooms globally. A few listed large corporates announce accumulation of BTC after their buddies have all bought in (Board members, C-suite executives, family, and friends, etc.)
~ Money printing does not stop as the deflationary force of technology is too severe; the new US government formed after Biden’s win begins to adopt MMT as its primary guidance of future economic theory, led by Steph Kelton.
~ The holiday season and strong seasonality pump BTC back to $20k for the first time. Hard rejection and price fall back to $14k.


~ BTC finally breaks $20k after multiple retests of overhead resistance sometime in spring
~ Almost weekly we see another corporation announcing vested interest in BTC
~ No longer in doubt that the asset class is in a bull market. Macro funds pile in. By year-end, we’re at $55k. Newspaper reports Bitcoin has now broken the $1 trillion mark. Most institutions begin scrambling to understand the asset class and set up “Digital Asset Investment teams”
~ Retail money flows to altcoins; Bitcoin is becoming too expensive for “retail” investors. The bitcoin community discusses possibly denoting BTC as sats, but majority of exchanges not interested as they derive most income from alt flows. However, most Bitcoin-only platforms switch to sats as the primary display format led by bitcoiners who now have considerable wealth and influence
~ Increasing talk that some smaller nations are now discussing the prospect of including Bitcoin on their central bank balance sheet
~ The first BTC-denominated corporate bond is launched


~ Those in power have established full BTC positions, and we begin to see subtle clues that some countries are possibly accumulating BTC
~ Private banks selling BTC structured products now out in full force; custody solutions are now institutional-grade. 50% of the world’s banks have some product/solution tailored around bitcoin. The other 50% scramble.
~ Marks the top as BTC momentarily exceeds the most valuable company by market cap (~$2.5 trillion in 2022 @ $130K price). The final days of the frenzy are filled with rumors that central banks have accumulated 10% of global supply, and that it may even form part of the IMF’s global recognized reserve currencies. Crypto Twitter reaches peak “I told you so”


~ The next bear market isn’t as severe as the last few; as the digital asset teams of various institutions are accumulating up to 2-5% of their AuM. It’s now commonly accepted that this asset class is here to stay and that even deploying $10 billion is no longer an issue in an asset class worth an aggregate $5 trillion.
~ BTC finds a floor 60% lower at $50K as smart money accumulates. CT screams for a 80% correction because mUh bItCoIn cYcLeS aNd fRaCtAls
~ Investment banks now have full-fledged research teams dedicated to digital assets. Calls for 80% correction too, so the smart money front-runs.
~ The middle class latches on to the wholecoining meme. “1 Bitcoin to secure a retirement; stack those sats”
~ The wealthy who are now increasingly composed of inherited wealth begin selling real estate/equities/bonds for Bitcoin but holds their BTC with their private bank. Realizing that Bitcoin supply is truly limited and sensing the “1 bitcoin to retire” meme; and that not every millionaire can own 1 bitcoin, many of the rich/ultra-rich scramble to buy 5–100 BTC each if only to cement their status as rich. 5–100 BTC costs $500K-10M (at $100k per BTC)
~ The winning product of the year is an automatic savings plan in bitcoin.


~ Bitcoin is back to trading near its all-time highs of $130K after the 2024 halving cycle, however, the effect is marginal but the markets wrongly attribute it to the halving supply squeeze, building a false narrative for the next cycle in 2028.
~ Institutional money now in full-play; on hindsight we’ll realize the 10-year steady bull-run has actually begun since last year in 2023, similar to the gold bull run from 2000 to 2011
~ More exchanges finally denominate BTC in sats. $100K BTC = 0.1 cent per sat. Logging into platform displays your stack as:
“11.7m satoshis ≈ $17,500”


~ Retail attempts to trade around the 2028 halving cycle. The halving cycle no longer have much of an impact, as demand now far outstrips supply changes
~ Many earlycoiners now sell between $200–400K, only to see it continue its relentless climb at a 30% annual rate
~ The first central bank announces the official addition to their balance sheets; all other central bank begins to FOMO. Cements BTC as a global reserve asset.
~ Governments ask that private ownership of bitcoin be transferred to regulated financial institutions such as their local bank where it will be held under custody. 70% of people do so.


~ Many of the early-coiners now buyback at near to $1M ($20 trillion market cap), finally equaling gold’s market cap at a price of $4000+
~ Bitcoin peaks and meanders under $1M for the next decade
~ Volatility is now <10% per year, merchants begin adopting it en-masse as a medium of exchange


~ 5 years of price stability leads to some merchants re-pricing certain goods in sat-terms
~ The lightning network crosses a billion channels created
~ Fiat does not go away, but most G20 countries decide to ban bitcoin as a medium of exchange for economic transactions. Ownership of bitcoin as an asset is encouraged as a store of wealth; private ownership is frowned upon and in some cases made illegal.

Technical: Confidential Transactions and Their Implementation Tradeoffs

As requested by estradata here:
It is a general issue that crops up at the extremes of cryptography, with quantum breaks being just one of the extremes of (classical) cryptography.

Computational vs Information-Theoretic

The dichotomy is between computationally infeasible vs informationally-theoretic infeasible. Basically:
Quantum breaks represent a possible reduction in computational infeasibility of certain things, but not information-theoretic infeasibility.
For example, suppose you want to know what 256-bit preimages map to 256-bit hashes. In theory, you just need to build a table with 2256 entries and start from 0x0000000000000000000000000000000000000000000000000000000000000000 and so on. This is computationally infeasible, but not information-theoretic infeasible.
However, suppose you want to know what preimages, of any size, map to 256-bit hashes. Since the preimages can be of any size, after finishing with 256-bit preimages, you have to proceed to 257-bit preimages. And so on. And there is no size limit, so you will literally never finish. Even if you lived forever, you would not complete it. This is information-theoretic infeasible.


How does this relate to confidential transactions? Basically, every confidential transaction simply hides the value behind a homomorphic commitment. What is a homomorphic commitment? Okay, let's start with commitments. A commitment is something which lets you hide something, and later reveal what you hid. Until you reveal it, even if somebody has access to the commitment, they cannot reverse it to find out what you hid. This is called the "hiding property" of commitments. However, when you do reveal it (or "open the commitment"), then you cannot replace what you hid with some other thing. This is called the "binding property" of commitments.
For example, a hash of a preimage is a commitment. Suppose I want to commit to something. For example, I want to show that I can predict the future using the energy of a spare galaxy I have in my pocket. I can hide that something by hashing a description of the future. Then I can give the hash to you. You still cannot learn the future, because it's just a hash, and you can't reverse the hash ("hiding"). But suppose the future event occurs. I can reveal that I did, in fact, know the future. So I give you the description, and you hash it and compare it to the hash I gave earlier. Because of preimage resistance, I cannot retroactively change what I hid in the hash, so what I gave must have been known to me at the time that I gave you the commitment i..e. hash ("binding").

Homomorphic Commitments

A homomorphic commitment simply means that if I can do certain operations on preimages of the commitment scheme, there are certain operations on the commitments that would create similar ("homo") changes ("morphic") to the commitments. For example, suppose I have a magical function h() which is a homomorphic commitment scheme. It can hide very large (near 256-bit) numbers. Then if h() is homomorphic, there may be certain operations on numbers behind the h() that have homomorphisms after the h(). For example, I might have an operation <+> that is homomorphic in h() on +, or in other words, if I have two large numbers a and b, then h(a + b) = h(a) <+> h(b). + and <+> are different operations, but they are homomorphic to each other.
For example, elliptic curve scalars and points have homomorphic operations. Scalars (private keys) are "just" very large near-256-bit numbers, while points are a scalar times a standard generator point G. Elliptic curve operations exist where there is a <+> between points that is homomorphic on standard + on scalars, and a <*> between a scalar and a point that is homomorphic on standard * multiplication on scalars.
For example, suppose I have two large scalars a and b. I can use elliptic curve points as a commitment scheme: I can take a <*> G to generate a point A. It is hiding since nobody can learn what a is unless I reveal it (a and A can be used in standard ECDSA private-public key cryptography, with the scalar a as the private key and the point A as the public key, and the a cannot be derived even if somebody else knows A). Thus, it is hiding. At the same time, for a particular point A and standard generator point G, there is only one possible scalar a which when "multiplied" with G yields A. So scalars and elliptic curve points are a commitment scheme, with both hiding and binding properties.
Now, as mentioned there is a <+> operation on points that is homomorphic to the + operation on corresponding scalars. For example, suppose there are two scalars a and b. I can compute (a + b) <*> G to generate a particular point. But even if I don't know scalars a and b, but I do know points A = a <*> G and B = b <*> G, then I can use A <+> B to derive (a + b) <*> G (or equivalently, (a <*> G) <+> (b <*> G) == (a + b) <*> G). This makes points a homomorphic commitment scheme on scalars.

Confidential Transactions: A Sketch

This is useful since we can easily use the near-256-bit scalars in SECP256K1 elliptic curves to easily represent values in a monetary system, and hide those values by using a homomorphic commitment scheme. We can use the hiding property to prevent people from learning the values of the money we are sending and receiving.
Now, in a proper cryptocurrency, a normal, non-coinbase transaction does not create or destroy coins: the values of the input coins are equal to the value of the output coins. We can use a homomorphic commitment scheme. Suppose I have a transaction that consumes an input value a and creates two output values b and c. That is, a = b + c, i.e. the sum of all inputs a equals the sum of all outputs b and c. But remember, with a homomorphic commitment scheme like elliptic curve points, there exists a <+> operation on points that is homomorphic to the ordinary school-arithmetic + addition on large numbers. So, confidential transactions can use points a <*> G as input, and points b <*> G and c <*> G as output, and we can easily prove that a <*> G = (b <*> G) <+> (c <*> G) if a = b + c, without revealing a, b, or c to anyone.

Pedersen Commitments

Actually, we cannot just use a <*> G as a commitment scheme in practice. Remember, Bitcoin has a cap on the number of satoshis ever to be created, and it's less than 253 satoshis, which is fairly trivial. I can easily compute all values of a <*> G for all values of a from 0 to 253 and know which a <*> G corresponds to which actual amount a. So in confidential transactions, we cannot naively use a <*> G commitments, we need Pedersen commitments.
If you know what a "salt" is, then Pedersen commitments are fairly obvious. A "salt" is something you add to e.g. a password so that the hash of the password is much harder to attack. Humans are idiots and when asked to generate passwords, will output a password that takes less than 230 possibilities, which is fairly easy to grind. So what you do is that you "salt" a password by prepending a random string to it. You then hash the random string + password, and store the random string --- the salt --- together with the hash in your database. Then when somebody logs in, you take the password, prepend the salt, hash, and check if the hash matches with the in-database hash, and you let them log in. Now, with a hash, even if somebody copies your password database, the can't get the password. They're hashed. But with a salt, even techniques like rainbow tables make a hacker's life even harder. They can't hash a possible password and check every hash in your db for something that matches. Instead, if they get a possible password, they have to prepend each salt, hash, then compare. That greatly increases the computational needs of a hacker, which is why salts are good.
What a Pedersen commitment is, is a point a <*> H, where a is the actual value you commit to, plus <+> another point r <*> G. H here is a second standard generator point, different from G. The r is the salt in the Pedersen commitment. It makes it so that even if you show (a <*> H) <+> (r <*> G) to somebody, they can't grind all possible values of a and try to match it with your point --- they also have to grind r (just as with the password-salt example above). And r is much larger, it can be a true near-256-bit number that is the range of scalars in SECP256K1, whereas a is constrained to "reasonable" numbers of satoshi, which cannot exceed 21 million Bitcoins.
Now, in order to validate a transaction with input a and outputs b and c, you only have to prove a = b + c. Suppose we are hiding those amounts using Pedersen commitments. You have an input of amount a, and you know a and r. The blockchain has an amount (a <*> H) <+> (r <*> G). In order to create the two outputs b and c, you just have to create two new r scalars such that r = r[0] + r[1]. This is trivial, you just select a new random r[0] and then compute r[1] = r - r[0], it's just basic algebra.
Then you create a transaction consuming the input (a <*> H) <+> (r <*> G) and outputs (b <*> H) <+> (r[0] <*> G) and (c <*> H) <+> (r[1] <*> G). You know that a = b + c, and r = r[0] + r[1], while fullnodes around the world, who don't know any of the amounts or scalars involved, can just take the points (a <*> H) <+> (r <*> G) and see if it equals (b <*> H) <+> (r[0] <*> G) <+> (c <*> H) <+> (r[1] <*> G). That is all that fullnodes have to validate, they just need to perform <+> operations on points and comparison on points, and from there they validate transactions, all without knowing the actual values involved.

Computational Binding, Information-Theoretic Hiding

Like all commitments, Pedersen Commitments are binding and hiding.
However, there are really two kinds of commitments:
What does this mean? It's just a measure of how "impossible" binding vs hiding is. Pedersen commitments are computationally binding, meaning that in theory, a user of this commitment with arbitrary time and space and energy can, in theory, replace the amount with something else. However, it is information-theoretic hiding, meaning an attacker with arbitrary time and space and energy cannot figure out exactly what got hidden behind the commitment.
But why?
Now, we have been using a and a <*> G as private keys and public keys in ECDSA and Schnorr. There is an operation <*> on a scalar and a point that generates another point, but we cannot "revrese" this operation. For example, even if I know A, and know that A = a <*> G, but do not know a, I cannot derive a --- there is no operation between A G that lets me know a.
Actually there is: I "just" need to have so much time, space, and energy that I just start counting a from 0 to 2256 and find which a results in A = a <*> G. This is a computational limit: I don't have a spare universe in my back pocket I can use to do all those computations.
Now, replace a with h and A with H. Remember that Pedersen commitments use a "second" standard generator point. The generator points G and H are "not really special" --- they are just random points on the curve that we selected and standardized. There is no operation H G such that I can learn h where H = h <*> G, though if I happen to have a spare universe in my back pocket I can "just" brute force it.
Suppose I do have a spare universe in my back pocket, and learn h = H G such that H = h <*> G. What can I do in Pedersen commitments?
Well, I have an amount a that is committed to by (a <*> H) <+> (r <*> G). But I happen to know h! Suppose I want to double my money a without involving Elon Musk. Then:
That is what we mean by computationally binding: if I can compute h such that H = h <*> G, then I can find another number which opens the same commitment. And of course I'd make sure that number is much larger than what I originally had in that address!
Now, the reason why it is "only" computationally binding is that it is information-theoretically hiding. Suppose somebody knows h, but has no money in the cryptocurrency. All they see are points. They can try to find what the original amounts are, but because any amount can be mapped to "the same" point with knowledge of h (e.g. in the above, a and 2 * a got mapped to the same point by "just" replacing the salt r with r - a * h; this can be done for 3 * a, 4 * a etc.), they cannot learn historical amounts --- the a in historical amounts could be anything.
The drawback, though, is that --- as seen above --- arbitrary inflation is now introduced once somebody knows h. They can multiply their money by any arbitrary factor with knowledge of h.
It is impossible to have both perfect hiding (i.e. historical amounts remain hidden even after a computational break) and perfect binding (i.e. you can't later open the commitment to a different, much larger, amount).
Pedersen commitments just happen to have perfect hiding, but only computationally-infeasible binding. This means they allow hiding historical values, but in case of anything that allows better computational power --- including but not limited to quantum breaks --- they allow arbitrary inflation.

Changing The Tradeoffs with ElGamal Commitments

An ElGamal commitment is just a Pedersen commitment, but with the point r <*> G also stored in a separate section of the transaction.
This commits the r, and fixes it to a specific value. This prevents me from opening my (a <*> H) <+> (r <*> G) as ((2 * a) <*> H) <+> ((r - a * h) <*> G), because the (r - a * h) would not match the r <*> G sitting in a separate section of the transaction. This forces me to be bound to that specific value, and no amount of computation power will let me escape --- it is information-theoretically binding i.e. perfectly binding.
But that is now computationally hiding. An evil surveillor with arbitrary time and space can focus on the r <*> G sitting in a separate section of the transaction, and grind r from 0 to 2256 to determine what r matches that point. Then from there, they can negate r to get (-r) <*> G and add it to the (a <*> H) <+> (r <*> G) to get a <*> H, and then grind that to determine the value a. With massive increases in computational ability --- including but not limited to quantum breaks --- an evil surveillor can see all the historical amounts of confidential transactions.


This is the source of the tradeoff: either you design confidential transactions so in case of a quantum break, historical transactions continue to hide their amounts, but inflation of the money is now unavoidable, OR you make the money supply sacrosanct, but you potentially sacrifice amount hiding in case of some break, including but not limited to quantum breaks.

Polkadot — An Early In-Depth Analysis — Part One — Overview and Benefits
Having recently researched Polkadot, as with other projects, I wanted to document what I had learnt, so that others may potential find it useful. Hopefully providing a balanced view, it will consist of three articles outlined below.
Part One — Polkadot Overview and Benefits (This article)
Part Two — In-Depth look at the Consensus
Part Three — Limitations and Issues
I will provide links throughout, providing reference to sections, as well as include a list of sources at the bottom of the article for further reading.


Frustrated with the slow development of Ethereum 2.0, Dr. Gavin Wood, co-founder of Ethereum and inventor of Solidity, left to begin work on Polkadot, a next generation scalable blockchain protocol that connects multiple specialised blockchains into one unified network. It achieves scalability through a sharding infrastructure with multiple blockchains running in parallel, called parachains, that connect to a central chain called the Relay Chain.
Whilst it shares some similarities with Ethereum 2.0, one key differentiator is that it uses heterogeneous sharding, where each parachains can be customised through the Substrate development framework, enabling them to be optimised for a specific use case and running in parallel rather than same across all shards. This is important as when it comes to blockchain architecture, one size does not fit all and all blockchains make trade-offs to support different features and use cases.
All parachains connect to the relay chain, which validates the state transition of connected parachains, providing shared state across the entire ecosystem. If the Relay Chain must revert for any reason, then all of the parachains would also revert. This is to ensure that the validity of the entire system can persist, and no individual part is corruptible. The shared state makes it so that the trust assumptions when using parachains are only those of the Relay Chain validator set, and no other. Since the validator set on the Relay Chain is expected to be secure with a large amount of stake put up to back it, it is desirable for parachains to benefit from this security.
This enables seamless interoperability between all parachains and parathreads using the Cross-chain Message Passing (XCMP) protocol, allowing arbitrary data — not just tokens — to be transferred across blockchains. Interoperability is also possible to other ecosystems through bridges, which are specifically designed parachains or parathreads that are custom made to interact with another ecosystem such as Ethereum, Bitcoin and Cosmos for example, enabling interoperability. Because these other ecosystems don’t use the same shared state of Polkadot, finality is incredibly important, because whilst the relay chain can roll back all the parachains, it can’t roll back the Ethereum or Bitcoin blockchains for example. This is discussed further in part three.
The relay chain is responsible for the network’s shared security, consensus and cross-chain interoperability. It is secured by Validators and Nominators staking the native DOT tokens. Ultimately scalability for the ecosystem is determined by how scalable the relay chain can be. The number of parachains is determined by the number of validators on the relay chain. The hope is to reach 1000 validators, which would enable around 100 parachains. With each parachain being capable of around 1,000 transactions per second.
Nominators stake their DOT tokens with validators they trust, with the validators likely charging a small commission to cover running costs. If a validator is found to have performed misconduct a percentage of the their stake but also the nominators stake will be slashed depending upon the severity. For Level 4 security threats such as collusion and including an invalid block then 100% of the stake will be slashed.What’s really important to understand is that both the validators own stake and the nominated stake will be slashed, so you could lose all your DOT that you have staked against a validator if they perform maliciously. Therefore, it’s very important not to just try and maximise rewards and being oblivious to the risk, not only can you lose all your DOT, but you are making the entire system less secure (addressed in part three). There have already been several minor slashing incidents so far, so something to really consider.

Auction for Parachain Slots

Due to the limited number of parachain slots available, there needs to be a method to decide who gets a parachain slot. This is achieved through a candle-auction where participants bid with DOT to secure a lease on a parchain slot to secure a 6 — 24 month period, with the highest bidders winning. DOT isn’t spent, but rather locked for the duration of the lease and unable to participate in staking and earn rewards. In the event they are unsuccessful in securing a further slot, then the lease expires and the DOT will be returned.
Of the 100 parachain slots that they hope to be able to accommodate, between 10 and 30 will be reserved for system parachains, with the remaining available for either auction slots or used for parathreads. Whilst the DOT is returned, due to the limited number of slots available this could result in significant amounts of DOT needing to be acquired to secure a slot. How the auction mechanics effect the price of DOT also remains to be seen, with potentially a rise from the start of the auction, followed by a fall before the lease ends and the DOT are returned. The plan is to continuously have a small amount of parachain auctions going throughout the year, to minimise any unwanted effects. How comfortable developers will be with locking significant amounts of funds in a highly volatile asset for an extended amount of time, also remains to be seen. They could also be in a position where they can no longer afford to keep their lease and have to downgrade to a parathread (providing the application will still function with the reduced performance or migrate to another platform). See this article for more details on the auction mechanism


For applications that don’t require the guaranteed performance of a parachain or don’t want to pay the large fees to secure a parachain slot, then parathreads can be used instead. Parathreads have a fixed fee for registration that would realistically be much lower than the cost of acquiring a parachain slot and compete with other parathreads in a per-block auction to have their transactions included in the next relay chain block. A portion of the parachain slots on the Relay Chain will be designated as part of the parathread pool.
In the event that a parachain loses its slot then it can transition to a parathread (assuming the application can still function with the reduced and varied performance of sharing the slot between many). This also enables small projects to start out with a parathread and then upgrade to a parachain slot when required.


DOT is the native token of the Polkadot network and serves three key functions. (i) It is staked to provide security for the relay chain, (ii) to be bonded to connect a chain to Polkadot as a parachain and (iii) to be used for governance of the network. There is an initial total supply of 1 billion DOT with yearly inflation estimated to be around 10% providing the optimal 50% staking rate is achieved, resulting in rewards of 20% to those that stake (net 10% when take into account inflation). Those that don’t stake lose 10% through dilution. Should the amount staked exceed the optimal 50% then reward rates reduce as well as inflation to make staking less attractive. Likewise if its below 50% then rewards and inflation rate will be higher to encourage staking. Staking isn’t risk free though as mentioned before.


Polkadot employs an on-chain governance model where in order to make any changes to the network, DOT holders vote on a proposal to upgrade the network with the help of the Council. The council is an entity comprising a 23 seats each represented by an on-chain account. Its goals are to represent passive stakeholders, submit sensible and important proposals, and cancel dangerous or malicious proposals. All DOT holders are free to register their candidacy for the Council, and free to vote for any number of candidates, with a voting power proportional to their stake.
Any stakeholder can submit a public proposal by depositing a fixed minimum amount of DOTs, which stays locked for a certain period. If someone agrees with the proposal, they may deposit the same amount of tokens to endorse it. Public proposals are stored in a priority queue, and at regular intervals the proposal with the most endorsements gets tabled for a referendum. The locked tokens are released once the proposal is tabled. Council proposals are submitted by the Council, and are stored in a separate priority queue where the priorities are set at the Council’s discretion.
Every thirty days, a new proposal will be tabled, and a referendum will come up for a vote. The proposal to be tabled is the top proposal from either the public-proposal queue or the Council-proposal queue, alternating between the two queues.
The Technical Committee is composed according to a single vote for each team that has successfully and independently implemented or formally specified the protocol in Polkadot, or in its canary network Kusama. The Technical Committee is the last line of defence for the system. Its sole purpose is detecting present or imminent issues in the system such as bugs in the code or security vulnerabilities, and proposing and fast-tracking emergency referenda.


Whilst parachains aren’t currently implemented at this stage, there is a rapidly growing ecosystem looking to build on Polkadot with substrate. Polkadot’s “cousin”, the canary network Kusama used for experimentation, was launched last year by the same team and contributes to the early growth of the overall ecosystem. See here for a list of the current projects looking to build on Polkadot and filter by Substrate based.
Now that we have covered the basics, in part two I will explain how the consensus mechanism in Polkadot works and covering more of the technical aspects.

UYT Main-Net pre-launching AMA successfully completed with a blast

7 pm, 29th September 2020 Beijing time the UYT Main-Net pre-launching AMA successfully completed with a blast!
Here is a full record of the AMA:
Host: Hello everyone, it’s a great honor to host the first AMA of UYT network in China. Today, we have invited the person in charge of UYT Dao.
Let’s ask Mr. Woo to introduce himself Woo: Hello, I’m Ben. I’ve met you in the previous global live broadcast. I’m the director of UYT Dao and the founder of IGNISVC. At present, I’m the CEO of the TKNT foundation and have been engaged in the blockchain industry.
Q1. At present, different types of blockchains have emerged, but cross-chain interaction is still suffering a lot. In your opinion, what is the necessity and significance of cross-chain?
Answer: The full name of UYT is to unite all your tokens, which is to integrate all public chains and increase the liquidity of the whole industry. Our purpose is not to create another public chain, but to become a platform for the exchange of value, technology, and resources of all public chains. What we need to solve is that each individual chain can circulate with each other.
The full name of UYT is to unite all your tokens, which is to integrate all public chains and increase the liquidity of the whole industry. Our purpose is not to create another public chain, but to become a platform for the exchange of value, technology, and resources of all public chains. What we need to solve is that each individual chain can circulate with each other.
Q2. The founder of Ethereum, V Shen, once wrote a cross-chain operation report for bank alliance chain R3, which mentioned three cross-chain methods. Which one does UYT belong to? Can you briefly introduce the cross-chain solution of UYT?
Answer: In Vitalik’s cross-chain report, there are three main cross-chain methods. The first is that both parties do not know that they are crossing the chain, or that they cannot “read” each other, such as the centralized exchange. The second way is that one of the links can read other chains, such as side-chain / relay chain. That is, a can read B, and B cannot read a; The third is that both a and B can read each other’s, which can achieve the value and information exchange between a, B, and the platform. UYT belongs to the third kind.
Our new official website will be online soon. Here are a few simple points: first of all, the architecture of UYT includes relay chain, parachain, parathreads, and bridges. In terms of ductility, it has exceeded almost all the public chains currently online.
In the UYT network, there are four kinds of consensus participants, namely collector, fisherman, nominator, and validator. The characteristics of this model are: first, all people can participate without loss. Secondly, as long as anyone makes more contribution to the ecology, he will get more rewards, otherwise, he will receive corresponding punishment.
The underlying layer of UYT is the substrate, which uses the rust programming language. Rust is committed to becoming a programming language that can solve the problems of high concurrency and high-security systems elegantly. This is also a great advantage that we are different from other blockchain projects in technology.
Q3. What are the roles in the UYT network? What are their respective functions?
Answer: After the main network of UYT is online, there will be four roles: collector, fisherman, nominator, and validator, which is totally different from the current system of the test network.
The collector, in short, is responsible for collecting all kinds of information in the parallel chain and packaging the information to the verifier.
Fishermen, to put it bluntly, is fishing law enforcement, which specifically checks out malicious acts and gets rewards after being checked out.
The nominator, in fact, is a group of rights and interests. The verifier is its representative, and they entrust the deposit to the verifier.
Verifier, package new blocks in the network. It must mortgage enough deposits and run a relay chain client on a highly available and high bandwidth machine. It can be understood as a mining pool. It can also be understood as the node in the current UYT DAPP.
Q4. What is the mining mechanism of the UYT network?
The only way to obtain UYT after its issuance is to participate in mining activities. In the initial stage, the daily constant output times of UYT are set to 1440000, and the cycle of bitcoin is halved. Mining rewards can be obtained in the following five ways:
1) Asset pledge mapping mining 2) Become the intermediate chain node of uyt network 3) Recommendation and reward mechanism 4) Voting reward 5) UYT network Dao will take out 10% of gas revenue from block packaging for community construction and reward of excellent community personnel
Q5. The rise and fall of the blockchain are very fast. In order to give investors confidence, is there a detailed development plan, implementation steps, and application direction of UYT network in the next few months?
Answer: UYT Network test network has been running stably for a year. After the main network is launched, all mechanisms will undergo major changes.
The relationship between the UYT test network and the main network can be understood as the relationship between KSM (dot test network) and dot the main network, and the feasibility of the technology can be reflected more quickly by the UYT test network because of its faster timeliness and all future technology updates Some will move to the main network after the stable operation of the test network.
In order to give users a better experience and give more rewards to excellent nodes, all Dao organizers are working hard for it.
The development team has completed the cross-chain of bitcoin and some high-quality Ethereum based tokens in the early stage, and now the code has all been open source. For other mainstream currencies, community members can apply for funds to develop. In order to develop the ecology and make a better technical reserve, we will set up a special ecological development fund when the main network goes online. The transfer bridge is our key funding direction. The maximum application amount of a team is as high as 100000 US dollars. In addition, if other public chains want to connect to UYT, they will get technical support. In order to encourage developers to participate in ecological construction, Dao also launched a series of grants to support development. Developers can directly pull the better applications on Eth and EOS directly, or develop new products according to their own advantages. These directions are now the focus of funding.
Due to the early online testing time of uyt network, it is based on the earlier version of substrate1.0. The on-chain governance mode can only be realized after the upgrade of 2.0 is completed.
At present, the upgrading work is going on steadily, and the on-chain governance will be implemented in the main network with the launch of the uyt main network.
As a heterogeneous cross-chain solution with high scalability and scalability, UYT network can perfectly bridge the parallel encryption system and its encryption assets in theory, and its wide applicability in the future can be expected. Therefore, we do not limit the areas where UYT network will play its advantages and roles. But in the general direction, there will be mainly DEFI and DEX ecological plates. From the industry, it can cover a wide range of fields, not only finance but also games, entertainment, shopping malls, real estate, and so on.
Q6、How can UYT help DEFI?
Answer: UYT network can not only link different public chains but also make parallel chains independent and interlinked. Just like the ACALA project some time ago, it has successfully obtained Pantera capital’s $7 million saft agreement. Although the concept of DEFI is very popular now, all DEFI products are still in the ecology of each public chain, and the cross-chain DEFI ecology has not been developed. UYT is to achieve cross-chain communication, value exchange, and develop truly decentralized financial services and products. For example, cross-chain decentralized flash cash, cross-chain asset support, cross-chain decentralized lending, Oracle machine, and other products. At present, our technical team is also speeding up the construction of infrastructure suitable for the landing of more DEFI products and services and is committed to creating a real cross-chain DEFI ecology, which is only a small step of UYT’s future plan.
Q7、TKNT should be one of the hottest projects in the UYT ecosystem recently. Please give us a brief introduction to the TKNT project and the value of TKNT in the UYT ecosystem. Why can TKNT increase 400 times in 7 days? And what is the cooperative relationship between UTC and TKNT?
Answer: I will answer each project from the technical and resource aspects. Let’s first introduce UTC. UTC is the token of Copernican network and the first project of UYT game entertainment ecology. In the future, it will be responsible for linking. Due to the high-quality public chain in the entertainment industry, because of the limited slots of UYT, each field will seek a high-quality partner and help the partner become the secondary relay chain of UYT. After the main network of UYT goes online, many chains will want to access UYT Greater value circulation, due to the limited external slots of UYT, the cost is also very high. At this time, you can choose to connect to UTC first, and then connect UTC to UYT. With more and more links with UYT, it will gradually evolve into a secondary relay chain of UYT network. UTC’s resources, online and offline, offline payment and offline entity applications, also have a very large community base.
The ecological partners have very good operation experience in the game industry. They will use blockchain technology to change the whole game entertainment industry to make it more transparent and fair. At the same time, there are enough entity consumption scenarios. This is also UYT Because of the reason why the network chose to cooperate with it, the UTC project has been supported by the UYT ecological fund. The support fund includes that after the main network is launched, it will also be the first ecological cooperation project supported by UYT. Because of the online time of the main network of UYT, UTC can’t directly form a chain at present and will give priority to issuing on Ethereum. TKNT is a new concept project TKN is the largest online centralized guessing game platform in the world at present. TKNT mixes bet mining and DEFI, so it can carry out fixed mining through platform games, build a system that can realize game participation and in application payment in all Dapps based on ERC20, and combine with various financial services.
The reason why TKNT has created a myth of 400 times in 7 days is that the TkN platform has a buyback plan. As we all know, the online quiz game entertainment platform has an amazing profit. Every quarter, the profit will be used to buyback. The strong profit support has led to the huge increase of token. In the future, all users can use UTC to participate in TkN games. Therefore, the main network of UYT is that Line is also of great significance to TKNT. With the maturity of UYT ecology and technology, TKNT can have a more powerful performance. If TKNT wants to link more public chains, it needs to access UYT network, and realize a bigger vision with cross-chain interaction of UYT. After TKNT was launched on the exchange, the highest price has risen to $14, and now it has dropped to about $2.50. You will see that it will once again set a record high and create greater miracles. You will also see that $3 will be the best buying point for TKNT, because there will be several major moves in TKNT, and the global MLM plan will be launched on October 7 in Korea, China, and other countries There will be many marketing teams in Europe to promote TKNT, including As a shareholder of TkN, TKNT will also make every effort to promote TKNT. Secondly, TKNT will be launched next month on the largest digital currency exchange in South Korea, and Chinese users will see the shadow of TKNT on Binance in November. Of course, the decentralized trading platform of UYT will also be launched in the future.
Q8. What is the significance of the launch of UYT’s main network for the industry and ecology?
Answer: UYT is one of the few cross-chain platform projects in the industry at present.
There are many public chains and coin issuing projects. Why? Because of less work, more money. However, there are very high technical and capital requirements for cross-chain and platform. This barrier is very high, so almost no project side is willing to do this. But once this is done, it will be of great significance to the whole industry of digital currency and blockchain.
Because it will subvert the current situation of the whole currency circle and chain circle acting on their own, and the painting land is king. Let each independent ecosystem achieve a truly decentralized and trust-free cooperative relationship. This huge change will promote the whole industry to develop into a healthy and virtuous circle macro ecosystem.
Q9. The slogan of many project supporters is that UYT should surpass Ethereum. What is the difference in technology between UYT network and Ethereum?
Answer: Thank you so much for supporting UYT. In fact, the correct understanding is that UYT is the next era of Ethereum. First of all, UYT has a different vision from Ethereum.
Before the emergence of UYT, Ethereum, and EOS, no matter how well they developed, belonged to the era of a single chain. The popular metaphor is a LAN. However, UYT can realize the interoperability of each chain and bring the blockchain into the Internet era. Secondly, UYT is far superior to Ethereum in technology. It mainly includes three aspects: shared security, heterogeneous cross-chain, and no fork upgrade.
In the case that Ethereum 2.0 has not been implemented, UYT is the most friendly bottom layer for the DFI projects and other Dapps on Ethereum. Now, the hair chain architecture substrate of UYT is compatible with Ethereum smart contract language solidity, so eth developers can easily migrate their smart contracts to UYT.
Up to now, there is no good solution to the congestion problem of Ethereum, while UYT network not only solves the network congestion problem. What’s more, UYT can easily realize one-click online upgrade, instead of having to redeploy a set of contracts on Ethereum for each version upgraded and then require users to follow them to migrate the original assets from the old contract to the new contract. Developers can quickly and flexibly iterate their own protocols to change their application solutions according to the situation, so as to serve more users and solve more problems. At the same time, they can also repair the loopholes in the contract very quickly. In the case of hacker attacks, they can also solve the hacker stealing money and a series of other problems through parallel chain management. We can find that for Ethereum, UYT not only solves the congestion problem we see in front of us but also provides the most important infrastructure for the future applications such as DFI on Ethereum to truly mature into an open financial application that can serve all people. It also opens the Web 3.0 era of the blockchain industry. In terms of market value, Ethereum currently has a strong ecological construction, with a market value of US $40 billion. UYT will also focus on the development of this aspect after the main network goes online. No matter in terms of market value or ecological construction, I have enough confidence in UYT, after all, we are fully prepared.
Q10. What is the progress of the ecological construction of UYT? What opportunities do current ecological partners see in UYT or what changes may be brought about by UYT ecology?
Answer: After the main network of UYT goes online, there will be a series of ecological construction actions, and more attention will be paid to establishing contact with traditional partners. Cross-chain decentralized flash cash, cross-chain asset support, cross-chain decentralized lending, Oracle machine, and other products will also be the key cooperation direction of UYT.
UYT will give priority to the game and entertainment industry because this industry is most easily subverted by blockchain. As the ecological construction of UYT gets bigger and bigger, the future slots will become more and more expensive. The earlier you join UYT ecology, you will get more support from the ecological fund because the ecological fund is also limited. From the perspective of token value-added, all the project parties will cooperate with the project side in the future, and the project side needs to pledge a certain number of UYT to bid for slots, except for ecological rewards, others need to be purchased from market transactions.
The difference between the pledge here and the pledge we understand is that the UYT of the ecological partner participating in the auction pledge cannot enjoy the computing power for mining.
UYT main network has several opportunities for Eco partners to look forward to, the first point is bitcoin, bitcoin will be later than other assets late, but eventually, all the bubble and value will return to BTC, after the wave of DeFi bubble elimination, the focus will be very much in the bitcoin. UYT ecology can provide a more mature bottom layer for defi. In addition, now Ethereum’s DEFI is that of Ethereum and ERC 20 tokens, and the outbreak point of bitcoin has not yet arrived. Therefore, the DEFI of UYT ecology may be the next opportunity, which is a good opportunity for everyone.
The second opportunity is that after the main network goes online, the future UYT ecological projects will compete to bid for slots. In fact, the original intention of UYT is to realize the interconnection of all chains. The chain outside the UYT ecology also needs to communicate. The third is cross-fi. The BIFI is hatched on Ethereum, and the def on UYT can realize multi-chain operation. For example, TkN games or future UTC game platform users can call bitcoin on the UYT chain. This form only belongs to the decentralized finance in the cross-chain era of UYT, which can be called cross-fi.
Q11. Which exchanges will UYT go online next? What is the online strategy like?
Answer: As the founder of ignisvc and as UYT As the head of the Dao organization, we have always had good cooperative relations with major exchanges all over the world. TKNT will appear in several exchanges one after another. Hitbtc exchange in the United Kingdom, Upbit and Bithumb Exchange in South Korea, Bitfinex exchange in the United States, Binance exchange in China, BKEX exchange, and Kucoin exchange in China are all our partners, and they have been paying close attention to UYT Development, UYT is the public chain with the largest user base and the highest community participation in the cross-chain field, so the future value is immeasurable. If we have to go to the exchange, then we will choose one of the above exchanges to launch. But the vision of UYT is to create a fairer, safer, and transparent circulation in the field of digital currency, and users can master all the assets by themselves, Therefore, in the beginning, there is a simple DEX on the UYT wallet, which is a simple matchmaking transaction and is also an on-chain transaction. After the completion of the UYT DEX, more transactions may occur in the UYT DEX.
However, after the main network of UYT is online, centralized exchanges can directly access the block data synchronization of UYT, and it is not ruled out that some exchanges will directly go online for UYT trading. Such exchanges will not enjoy the support of the ecological support fund of UYT. The network project is a community-led project. Each cooperation plan of the exchange will be carried out in the way shared by the community in the future. Dao organization can only implement it according to the voting results.
Q12. What are the plans for the promotion of ecological development and market by the launch of UYT main network?
Answer: The launch of the main network will be completed around October 15.
On the offline side, due to the epidemic situation, we will jointly organize corresponding market activities with nodes in different countries. At present, there are three large-scale offline meetups that have been identified. We will also start a global roadshow when the epidemic is over.
On the online side, we have opened online Wechat, Kakao, Twitter, Reddit, and telegram communities. We will carry out AMA activities in various countries and promote them all over the world in various ways. Of course, we will launch MLM plans and cooperate with more marketing teams.

AMM + Limit Order, Will OneSwap Replace Traditional Exchange?

When a thing is denied, something new starts at a higher level.
The update and iteration of the currency circle takes only a few days.
On August 13, Yam, the token of a popular DeFi project, plummeted by 98%, while YFI, another DeFi cryptocurrency, outran the digital currency Bitcoin Gold by value under capital operation.
According to their familiarity with DeFi, blockchain investors in 2020 can be divided into two categories. The "New" investors are active in DEXs such as UniSwap and Balancer, striving for hundredfold returns on investment amid fake projects, while the "old" investors stick to mainstream cryptocurrencies and advocate value investment in the three major CEXs.
Despite its long history, DEX did not prosper until recently. It has processed transactions of over US$520 million in the past 24 hours, and the trading volume for the past week has exceeded the figure across 2019.
But still, many people are stranger to DEX.
I. Will DEX shuffle the existing trading market?
Upon discovering something new, you can describe it, but never evaluate it superficially.
UniSwap occupies 55% of the entire DEX market. Celebrities in the circle enjoy discussing the changes brought by UniSwap on social media and how it will change the existing trading landscape.
On August 5, Jay, CEO of OKEX Exchange, publicly stated that "UniSwap can hardly replace the current mainstream exchanges." on Weibo.
He also listed two reasons:
  1. With insufficient transaction depth, UniSwap cannot support large transactions;
  2. UniSwap cannot set prices independently, but has to follow the prices set by other exchanges.
He also recognized UniSwap’s AMM model in the post.
Soon this post was criticized by Dovy, the founding partner of Primitive Ventures, to the effect that Jay had quite limited knowledge about DeFi and the reasons he proposed did not hold good.
She also mentioned the advantages of a new generation of DEX represented by UniSwap:
Traditional exchanges determine the price and market value according to a small number of chips in the market. By comparison, AMM relies on the entire LP pool to contribute liquidity, and a small number of chips will not lead to severe fluctuations in the price. The price follows the curve of the static liquidity pool within a time range, rather than the manually controlled order book.
2. Is UniSwap good enough to replace centralized exchanges?
Neither OK or Binance had expected that one day their arch rival was not each other, but the newly emerging decentralized exchanges.
With totally different operating methods and business models, DEX and CEX have their own merits.
CEX comes with evident problems. Ordinary users do not trust its security due to the rampant data cheating. For project developers, CEX requires high fees for token listing and maintenance.
The advantage of CEX lies in its low threshold and mature business model.
Just as Jay said, DEXs represented by UniSwap are still faced with great challenges posed by user habits. For example, UniSwap does not support limit orders or the candlestick chart, and users need to rely on a third-party Ethereum wallet for operation.
The innovative AMM model allows ordinary users and small market makers to get involved and earn market-making fees, reducing costs and improving liquidity.
According to the trading volume at this time, UniSwap may not be able to replace mainstream exchanges, but it is good enough to replace second and third-tier exchanges.
3. Is OneSwap an upgraded version or a copy of UniSwap?
"The success of UniSwap proves the necessity of the DEX that does not require permission and supports AMM in the market. However, UniSwap comes with two shortcomings. One is the lack of support for limit orders, which greatly restricts trading methods and liquidity; The other is the excessive transaction cost and poor transaction efficiency due to the limited processing capacity of Ethereum." - Yang Haipo
Recently, OneSwap, known as the upgraded version of UniSwap, announced that it will hit the market in early September, and has received an investment of US$10 million from CoinEX.
To develop an open-source centralized trading platform like OneSwap, it is easy to replicate the technique. But among so many Swap applications in the market, what advantages does OneSwap have over UniSwap?
1. Limit orders
Neither buyers or sellers of UniSwap can set prices independently; instead, they need to follow the prices set by other exchanges. If they want to buy tokens at a specific price, they have no choice but to wait till tokens at such a price appear in UniSwap, a waste of time.
Continuing the good practices of centralized exchanges, OneSwap supports the traditional order book based on rapid exchange, offering more flexible trading methods and further enhancing the liquidity of digital assets.
2. The candlestick chart and depth map
Without an order book, UniSwap has been criticized for its simple transaction interface which does not even contain the basic candlestick chart. As a result, it cannot satisfy numerous traders’ demand for data analysis.
To benchmark against the centralized exchange in terms of user experience, OneSwap has introduced functions such as the candlestick chart, order ticket, and depth map. Just like centralized exchanges with professional charts, OneSwap provided the price trend, trading volume, depth, and other information of different cryptocurrencies for users to set out informed trading plans.
3. Liquidity mining + transaction mining
UniSwap’s AMM model is believed to be a vital catalyst for its explosive growth. With an additional incentive mechanism of transaction mining besides liquidity mining, OneSwap leaves more core benefits to its users.
OneSwap will charge the Taker a fixed percentage of transaction fees based on the transaction amount, while the Maker does not need to pay. The transaction fees are divided into two parts: 60% for liquidity and 40% for the repurchase and burning of ONES. In transaction mining, both liquidity providers and traders will receive ONES as an economic incentive.
The market is looking forward to a new product that is as user-friendly as CEX and as safe as DEX. Is OneSwap qualified to meet such demands?

AITD class third lesson:Revealing the Bitcoin's Fortune secret.
When we mention Bitcoin, many people's first impression is Bitcoin. In the current Financial investment products, Bitcoin's earning rate is ranked at the first place globally,which created many investment miracles. When we talk about why bitcoin is so valuable,fewer people can explain it clearly.
If we really want to understand the Fortune secrets of Bitcoin. First, we need to understand the historical birth backgrounds of Bitcoin and it's value logic.The outbreak of the Financial crisis was in 2008 worldwide, multiple international banks and financial institutions were going to file bankruptcy,many investors were losing all their Fortune, there was a recession happenned in the Financial Market.
At the end of 2008, a person who claimed to be Satoshi Nakamoto published Bitcoin White Paper "Bitcoin:A P2P Digital Cash System" on 1st November,has announced the birth of Bitcoin since then. In the beginning of 2009,Genesis Block was officially uploaded on chain .
The appearance of Bitcoin was bringing new directions and hopes to the dismal financial market at that moment.Comparing to traditional paper currency, Bitcoin is possessing the following two competitive advantages:
First, there are no central publishing organizations, which means that the generation of Bitcoin and flow of Bitcoin will not be controlled by any central organizations.Due to the effect of financial storm, multiple global banks were going to file bankruptcy, investors have no where to file complaint, people have negative feelings toward banks which held currency distribution rights.The creation of Bitcoin was avoiding the problem of "publisher break down" which investors are paying more attention to.
Second, Never exceed the limit. The total amount for Bitcoin distribution is 21million dollars, number setting has written in Smart contract.Tamper prove, distribution amount limitation, all these traits confirm the non-existance of Bitcoin inflation .Many countries are suffering inflation problems,the most typical example is Venezuela. Due to years of inflation, the economic situation is that " Bank note is cheaper than toilet paper".
Two revolutionized advantages allow Bitcoin to become the star of Financial industry ,pursued and flattered by many investors. At the sametime, the layer technique possessed tamper proved traits in Bitcoin, ensuring reliability for investor's each transaction .Therefore,Bitcoin's financial status and industry value are skyrocketing in 10years after Bitcoin created which can be considered as normal phenomenon.
According to the public emergence of Bitcoin,mainstream economists started changing their attitude towards Bitcoin. The beginning analysation topic for Bitcoin is that "Is Bitcoin a trap?", but now the topic turns to be "Will Bitcoin become the mainstream currency in the future?
Now, some countries and organizations are starting Bitcoin payments, people's acceptance rate is increasing for Bitcoin, which means that Bitcoin will be accepted by more countries around the globe as an encrypted currency industry lead.
Next episode preview: Consensus Algorithm ,Encrypted World's Fortune distribution standard rule.

"Swap" is Poised for Take-off

How popular is DeFi?
Link, known as the leader of the oracle machine, has increased by 305.19% for the past three months, with an investment return of 17,052%, climbing to the fifth spot in the cryptocurrency ranking list by market value in the short term;
Since its issuance, YFI, which has soared 350 times all the way, has attracted 630 million US dollars of investment in 5 days, and was even dubbed the next Bitcoin in this circle;
From Comp for lending, KNC and BAL, governance tokens for decentralized exchanges, to SNX which is a stable currency payment network, various governance tokens of the DeFi ecosystem have emerged in an endless stream, stirring the blood in the market.
Such a boom is not only reflected in the currency price, but also pushes the brand new DEX based on the AMM (automated market making) model an overnight hit. UniSwap, known as the next-generation casino, has surpassed the world's first-tier centralized exchanges such as Binance, OKex, and Huobi in user activity, daily trading volume, and daily turnover.
With the rapid rise of UniSwap, the DEX threat theory has once again triggered heated discussions among the media and communities in the blockchain industry.
DEX on the Rise
The success of UniSwap is by no means something accidental. As early as 2018 when centralized exchanges suffered the hacker theft one after another, Vitalik Buterin, founder of Ethereum, predicted that the future lay in decentralized exchanges and that Ethereum, by developing a "better" decentralized platform, could empower the cryptocurrency community to regain the dominance from the centralized cryptocurrency exchange.
To realize the decentralized concept of returning to users their asset ownership, geeks in the blockchain industry have made many attempts.
Kyber Network, Bancor, Balancer, 0X, Curvefi, etc. are all DEXs based on Ethereum blocks. For a long time, affected by the performance of Ethereum and cross-chain issues, these DEXs were once stagnant.
With the lessons learned from Ethereum DEX, newcomers to the DEX have focused on high performance, high TPS, and rich assets as the ultimate goal for product development.
Amid the DEX threat theory, major exchanges have deployed their own public chain DEX products in a response to their respective development strategies: Binance launched Binance DEX on its Binance Chain, and Bittrex Exchange unveiled Ethfinex on the Ethereum and EOSfinex on the EOS blockchain, two platforms where users can exchange for fiat currencies; last year, CoinEx officially launched CoinEx Chain, a public chain dedicated to decentralized transactions, followed by CoinEx DEX.
Since the birth of the DEX in the blockchain world, this field has never run out of competition.
By independent development or other’s advantage?
From 2017 when it was established to 2019 as it stabilized, DEX has witnessed its annual trading volume skyrocketing from less than US$5 million to over US$2.5 billion. As DeFi gains fame and grows rapidly, DEX has grown into the most popular source of money, attracting a flood of speculators. In the past month, the trading volume of the global cryptocurrency market DEX has exceeded US$ 4 billion, more than twice the figure across 2019.
In the past two years, despite the increasingly in-depth exploration in the DEX, the cross-chain issue remains a stumbling block in its development path. DEX will not outperform CEX in the trading experience until a cross-chain solution is worked out.
The concept of DeFi went viral in 2019. With the continuous improvement of the DeFi ecosystem, the current Ethereum blockchain has developed into a complete decentralized financial system, covering mortgage lending, interest from deposit, leveraged trading, token exchange, identity authentication, and other infrastructure essential to traditional financial systems.
In addition to the mouth-watering profit, the DeFi ecosystem has also brought along explosive growth in both the type and quantity of digital assets, making DEX a market favorite. Compared with the DEX dedicated to public chains, the Ethereum-based DEX has been equipped with more possible functions and thus become more attractive thanks to the comprehensive supplementary infrastructure on Ethereum.
This also presents DEX pioneers with new opportunities. Dubbed “Swap’s summer”, the summer of 2020 has seen a market rush in Swap development after UniSwap became a hit.
Miniswap, Justswap, and btswap are no more innovative than UniSwap according to their product structures and white papers.
By comparison, OneSwap has injected unique essence into its product design and governance model based on UniSwap's automated market making.
Upgraded UniSwap
OneSwap, which has a double mining model + order book, has received an investment of tens of millions from CoinEx even before the product is launched. It is known that OneSwap is jointly developed by a group of technology geeks who have engaged in the cryptocurrency community for many years. The project was initiated by a member of the team in an attempt to upgrade UniSwap after he experienced the convenient AMM enabled by UniSwap.
Without limit orders, users have to trade in the price set by the platform, which, however, compromised their experience. In addition, the lack of liquidity mining and transaction mining rewards cannot reduce the losses of liquidity providers caused by unilateral market conditions.
"DEX still has much room for perfection, and could even surpass CEX in trading experience"
The OneSwap development team always believes that UniSwap still has a long way to go before it becomes the strongest DEX in the DeFi ecosystem. They have endeavored to, relying on their abundant experience in exchange product development and digital currency trading, create the most powerful DEX product in the DeFi ecosystem based on smart contracts.
OneSwap is called the “upgraded UniSwap” in the community. By the combination of the Constant Product Market Maker (CPMM) model in the Uniswap project and the on-chain order book, it reduces restrictions on users’ trading, and, through its OneSwap Wallet, improves user interaction methods and further enhances their experience in trading and product usage.
OneSwap boasts one-click token issuance and listing essential to DEX. Unlike the listing review mechanism on Binance DEX, the setting of OneSwap is more consistent with the concept of decentralization. Anyone can put his or her good projects and ideas, if any, into practice through OneSwap without permission.
In terms of product design, OneSwap will add to its function menu the Candlestick chart, order form, and depth chart according to user habits, apart from limit orders. These functions will offer OneSwap users an experience as smooth, easy-to-use, and convenient as in the CEX.
A new source of money? A two-pronged platform with transaction mining + liquidity mining
To support on-chain governance, OneSwap will issue a ERC20 governance token called ONES. The total number of ONES remains constant at 100 million, 50% of which will be used as community funds to support the construction of the OneSwap ecosystem and 50% will be owned by the OneSwap team. Community funds can be applied for through on-chain governance. 5% of the part held by the team will be unlocked initially, and the rest will be unlocked at a rate of 5% every six months until all is unlocked after four and a half years.
After the OneSwap product was launched, the OneSwap team will take part of the initially unlocked tokens as airdrop rewards for the open beta. Then OneSwap will officially start liquidity mining and transaction mining, and the governance token ONES will also be simultaneously launched on centralized trading platforms across the world. The first round of mining activities will last for one month, and mining rewards are yet to be made public.
Liquidity mining is a popular way of obtaining governance tokens in the DeFi ecosystem. Well-known DeFi projects including COMP, Cure, and Banner have all enabled liquid mining.
Transaction mining could date back to 2018 when Fcoin grew popular.
The transaction mining model initiated by Fcoin in 2018 once set off a bull market that year, pushing many investors into financial freedom in the rush of transaction mining. In addition, transaction mining based on the DeFi ecosystem is still a blue ocean, which is not common in the current market. The success of OneSwap's double mining model, if possible, would surely start a craze in the cryptocurrency market.
The OneSwap team has not yet announced specific mining rules, but disclosed that it has developed the smart contract code. To ensure the product security, OneSwap will invite three well-known security agencies in the blockchain industry to audit the code and announce the auditing results in early September at the soonest.
DeFi did not rise to fame without reason in 2020. Such overnight popularity is an inevitable result of Ethereum's efforts to build a decentralized consensus mechanism and improve infrastructure in the past few years. Ethereum has almost become the only public chain in the DeFi circle and the only construction base for well-known DEX. If OneSwap succeeds, it means a huge breakthrough for both DeFi and Ethereum, and decentralization in its true sense is around the corner.

Trading expenses are incurred when an order is prepared by means of the Bittrex worldwide matching engine. While an order is being executed, the purchaser and the vendor are charged a rate primarily based on the order’s amount. The fee charged by Bittrex exchange is calculated by the formula amount * buy rate * fee. There aren't any charges for placing an order which is not being executed so far. Any portion of an unfinished order will be refunded completely upon order cancelation.
Prices vary depending on the currency pair, monthly trade volume, and whether the order is a maker or taker. Bittrex reserves the right to alternate fee quotes at any time, including offering various discounts and incentive packages.

Monthly Volume

Your buying and selling volume affects the fee you pay for every order. Our expenses are built to encourage customers who ensure liquidity in the Bittrex crypto exchange markets. Your buying and selling charges are reduced according to your trade volume for the last 30 years in dollars.
Bittrex calculates the 30-day value every day, updating every account's volume calculation and buying and selling charge between of 12:30 AM UTC and 01:30 AM UTC every day.
You can check your monthly trade volume by logging in and opening Account > My Activity.

6. Withdrawing Funds

Withdrawing any type of funds is likewise simple. You can profit by buying and selling Bitcoin, Ether, or any other cryptocurrency.
You determine the crypto address—to which the amount will be credited—and the transaction amount. The withdrawal fee will be automatically calculated and shown right away.
After confirming the transaction, the finances will be sent to the specified addresses and all that you need to do is to wait for the community to confirm the transaction.
If the 2FA is enabled, then the user receives a special code (via SMS or application) to confirm the withdrawal.

7. How to Trade on Bittrex Global

Currency selling and buying transactions are performed using the Sell and Buy buttons, accordingly.
To begin with, the dealer selects a currency pair and sees a graph of the rate dynamics and different values for the pair.
Below the chart, there is a section with orders where the user can buy or sell a virtual asset.
To create an order, you just need to specify the order type, price, and quantity. And do not forget about the 0.25% trade fee whatever the quantity.
For optimum profit, stay with liquid assets as they can be quickly sold at a near-market rate effective at the time of the transaction. Bittrex offers no referral program; so buying and selling crypto is the easiest way to earn.

Order Types

Bittrex helps you alternate Limit and Stop-Limit orders.
A limit order or a simple limit order is performed when the asset fee reaches—or even exceeds—the price the trader seeks. To execute such an order, it is required that there's a counter market order on the platform that has the identical fee as the limit order.

Differences between Limit Order and Stop Limit Order

A stop limit order is a mixture of a stop limit order and a limit order. In such an application, charges are indicated—a stop charge and the limit.

Stop Limit Order Purpose

Trade Terminal

Let’s discuss how you could trade conveniently with our service.
The key features include a user-friendly interface and precise currency pair statistics (timeframe graphs, network data, trade volumes, and so forth).
The platform’s top-notch advantage is handy, easy-to-analyze, customizable charts. There is also a column for quick switching between currency pairs and an order panel beneath the fee chart. Such an all-encompassing visual solution helps compare orders efficiently and in one place.
You can use the terminal in a day or night mode; when in the night mode, the icon in the upper-right corner changes and notice the Bittrex trading terminal in night mode is displayed. The main menu consists of 4 sections: Markets, Orders, Wallets, Settings.
Markets are the trade section. Bittrex allows handling over 270 currency pairs.
Orders. To see all open orders, go to OrdersOpen.
To see completed orders, go to OrdersCompleted.
Wallets. The Wallets tab displays many wallets for all cryptocurrencies supported by the exchange and the current balance of each of them.
After refilling the balance or creating a buy or sale order, you will see all actions in the section. Bittrex allows creating a separate wallet for every coin. Additionally, you can see how the coin price has changed, in terms of percentage, throughout the day.
Here’s what you can also do with your wallets:
  • Hide zero balances: hide currencies with zero balance
  • Green and red arrows: replenish balance/withdraw funds
  • Find: search for a cryptocurrency
The Settings section helps manage your account, verification, 2FA, password modification, API connection, and many more.

How to Sell

The process of selling crypto assets follows the same algorithm. The only difference is that after choosing the exchange direction, you need to initiate a Sell order. All the rest is similar: you select the order type, specify the quantity and price, and click Sell *Currency Name* (Sell Bitcoin in our case).
If you scroll the screen, the entire history of trades and orders will be displayed below.


You can make a long deal or a short deal. Your choice depends on whether you expect an asset to fall or rise in price.
Long positions are a classic trading method. It concerns purchasing an asset to profit when its value increases. Long positions are carried out through any brokers and do not require a margin account. In this case, the trader’s account must have enough funds to cover the transaction.
Losses in a long position are considered to be limited; no matter when the trade starts, the price will not fall below zero with all possible errors. Short positions, in contrast, are used to profit from a falling market. A trader buys a financial instrument from a broker and sells it. After the price reaches the target level, the trader buys back the assets or buys them to pay off the initial debt to the broker.
A short position yields profit if the price falls, and it is considered unprofitable the price matches the asset value. Performing a short order requires a margin account as a trader borrows valuable assets from a broker to complete a transaction. Long transactions help gain from market growth; short from a market decline.

Trade via API

Bittrex also supports algorithmic trading through extensive APIs (application programming interface), which allows you to automate the trading process using third-party services.
To create an API key, the user must enable the two-factor authentication 2FA, verify their account, and log in to the site within 3 minutes.
If all the requirements of the system are fulfilled, you can proceed to generate the API key. Log in to your Bittrex account, click Settings. Find API Keys. Click Add new key (Create a new key).
Toggle on / off settings for READ INFO, TRADE, or WITHDRAW, depending on what functionality you want to use for our API key.
Click Save and enter the 2FA code from the authenticator → Confirm.
The secret key will be displayed only once and will disappear after the page is refreshed. Make sure you saved it!
To delete an API key, click X in the right corner for the key that you want to delete, then click Save, enter the 2FA code from the authenticator and click Confirm.

Bittrex Bot, a Trader’s Assistant

Robotized programs that appeared sometimes after the appearance of cryptocurrency exchanges save users from monotonous work and allow automating the trading process.
Bots for trading digital money work like all the other bots: they perform mechanical trading according to the preset parameters.
Currently, one of Bittrex’s most popular trading bots is Bittrex Flash Crash Buyer Bot that helps traders profit from altcoin volatility without missing the right moment.
The program monitors all the market changes in the market every second; also, it even can place an order in advance. The Bittrex bot can handle a stop loss—to sell a certain amount of currency when the rate changes in a favorable direction and reaches a certain level.

8. Secure Platform

Bittrex Global employs the most reliable and effective security technologies available. There are many cases of theft, fraud. It is no coincidence that the currency is compared to the Wild West, especially if we compare the 1800s when cowboys rushed to the West Coast of America to earn and start something new in a place that had no rules.
Cryptocurrency is still wild. One can earn and lose money fast. But Bittrex has a substantial security policy thanks to the team’s huge experience in security and development for companies such as Microsoft, Amazon, Qualys, and Blackberry.
The system employs an elastic, multi-stage holding strategy to ensure that the majority of funds are kept in cold storage for extra safety.
Bittrex Global also enables the two-factor authentication for all users and provides a host of additional security features to provide multiple layers of protection.
Bittrex cold wallet:

How to Pass IP Verification

To ensure higher security of your Bittrex Global account, the system requires all users to approve each new IP address through an email confirmation. This IP verification procedure is required every time you attempt to log in from a new IP Address.
Confirming your IP address.
The new IP address must be confirmed from the device that you are using to access Bittrex Global. This means that you must follow the CLICK HERE TO LOGIN link in an email on the device that you want to use to access your account.
To ensure even more security, Bittrex Global supports whitelisting of IP addresses and Crypto addresses. These two features can help protect the account in the event of credentials or API key loss.

How to Add IP Address to Whitelist

By setting one or more whitelisted addresses, you are telling Bittrex Global to only authorize trades or withdrawals from those IPs. This concerns both the web interface and API-based trades or withdrawals. To do this, click IP Whitelist in Site Settings.

How to Add Crypto Address to Whitelist

By setting a withdrawal address, you are telling Bittrex Global to authorize withdrawals only to that address.
This concerns both the web interface and API based withdrawals.
Note that when opting into this feature, you need to specify a withdrawal address would like to withdraw funds from for every currency. To do this, click Withdrawal Whitelist in the Site Settings section. The example below shows a BTC address.

OneSwap: An Upgraded Version of UniSwap! An Ace DEX in the DeFi Ecosystem

Powerful DeFi

DeFi, or decentralized finance, represents the hottest topic in the blockchain industry and Ethereum ecosystem this year. According to data from DeFi Market Cap, the total market value of the top 100 projects in the DeFi ecosystem has exceeded US$6.9 billion, a tenfold increase in just three months. DeFi, which rose to fame in 2019, eventually regains its popularity in 2020.
Judged from another perspective, there have been signs for its popularity overnight. At the beginning of 2019, all major exchanges announced that they would enter the DEX field to define the trading model of cryptocurrencies in a brand new way. As one of the three major parts of DeFi, DEX has grown steadily in the cryptocurrency market, and has become the best choice for blockchain entrepreneurs to seek long-term development as centralized exchanges are confined to a bottleneck. Even though research shows that DEX contributed less than 1% to the overall transaction volume last year, there have appeared hundreds of new DEX platforms in the market for the past year.
Driven by DeFi, the trading volume of DEX in 2020 will grow to nearly US$5.1 billion. That is six times as much as the figure in 2019, with an increase of US$1.5 billion in June alone. In particular, Uniswap, the star DEX in the DeFi ecosystem, has outperformed its counterparts by transaction volume, with a daily transaction volume of more than US$100 million.
UniSwap is a token transaction protocol on Ethereum. It is a set of contracts deployed to the Ethereum network. All transactions are carried out on the chain. Anyone can exchange and withdraw tokens in UniSwap without registration or identification. UniSwap adopts automated market making (AMM), so users can buy and sell orders quickly without pending orders; at the same time, users can freely list coins and create trading pairs on Uniswap, and even get a share of the transaction fee as liquidity providers for tokens.
Once launched, UniSwap has been favored by the community and project developers. The super coins that may generate profits 100 times the cost as well as its efficient, easy-to-use product experience have attracted a large number of users who used to struggle in centralized exchanges for a long time. UniSwap has become the most popular DEX platform overnight, and the slippage rate of its mainstream DeFi project is even far lower than the figure of the first-tier exchanges.

Hidden dangers under madness

No listing fees, no delisting risks, and no restrictions at all.
In June alone, more than a dozen of super coins that may generate profits 100 times or even 1,000 times costs have been listed on UniSwap. Yet under such prosperity, crisis is simmering. Among the numerous projects, both good and bad, the platform is full of swindlers deceiving many investors; in addition, in spite of UniSwap’s efficient trading, the automated market making (AMM) lacks support of order book. All purchases on UniSwap are subject to the prices set thereon only, which greatly confines user’s transaction demands; what’s worse, UniSwap does not issue its own value tokens, and UniSwap’s liquidity providers only get the income from the transaction fee, leaving themselves risking losses for market making under unilateral conditions.
In general, UniSwap has been successful temporarily compared to other DEX. However, as the DeFi ecosystem gradually moves toward a broader market, its defects will hinder liquidity providers from gaining profits and users from having their diverse transaction needs met.

Upgraded UniSwap

With the globalization of the DeFi ecosystem, a DEX that can undertake thousands of projects and offer an excellent trading experience is needed in the market. After conducting in-depth research on all DEX products in the DeFi ecosystem, the OneSwap team combined user needs and market trends to create a fully decentralized transaction protocol on smart contracts—OneSwap, as we know it.
On July 29, 2020, OneSwap was officially launched on its official website.
OneSwap is a fully decentralized exchange protocol on Ethereum, with permission-free token listing and automated market making.
(I)Combination of automated market making and limit order
Similar to UniSwap, OneSwap applies the automated market making (AMM). Users can establish liquidity pools without permission, and make markets through automated algorithms. Liquidity providers can provide liquidity reserves for promising tokens. OneSwap will exchange two ERC20 Tokens in the liquidity pool based on a constant product algorithm, and the commissions obtained will be distributed to liquidity providers. Unlike UniSwap, OneSwap supports liquidity mining simultaneously. Through liquidity mining on OneSwap, users provide liquidity for the transaction token pool. For example, to provide liquidity for the ETH-AMPL pool, the liquidity provider can deposit ETH and AMPL tokens in a certain proportion, and then, according to the rules of the platform, gain both tokens and transaction fees on OneSwap.
In addition, in order to meet the diverse transaction needs of users, OneSwap will support the order book while adopting the AMM.
OneSwap's order book will be matched on the chain, which is different from the off-chain matching and on-chain clearing modes of other platforms. Since there is no centralized off-chain order book, OneSwap allows users to separately place orders at multiple different front ends developed by various vendors, without suspending its services due to failure in any vendor’s server. Based on the order book, users will not be forced to trade at the price set by the platform but buy or sell orders at a fixed price by themselves. That will be more flexible.
(II) Permissionless token listing and trading pair creation
For a decentralized trading platform, its restrictions determine how much freedom it can offer.
Unlike most pseudo-DEXs, OneSwap supports permission-free token creation, listing, and transactions without any listing fees. Users can trade on OneSwap with all Tokens that meet the ERC20 standard. In the past, small and medium-sized entrepreneurial teams needed to pay a large amount of listing fees apart from expenses for daily operation and project promotion. That was risky for them as it might make them unable to survive due to lack of funds. Fortunately, OneSwap can meet their needs including token listing, storage, transaction, and market making.
(III)Product experience more similar to CEX
The product design and functions of DEX on the current market are relatively simple, yet the threshold for use is high. Considering that, OneSwap develops a feature-rich, and easy-to-use operation interface based on users’ trading habits. Related functions such as K-line, depth map, and transaction history can even be expected.
OneSwap refines and upgrades the advantages of major platforms on the basis of UniSwap, Curve, and Balancer, and combines the product design of the CEX platform to create a more powerful UniSwap. We are confident that OneSwap will bring fresh surprises to the DeFi ecosystem and community.

Booming Ethereum

In response to the DeFi rush and the Ethereum 2.0 beacon chain, Ethereum has maintained an upward trend for six consecutive days and the price has kept rising from US$200 to a new high of US$330.
Driven by Ethereum, the digital currency market has remained prosperous overall as the Bitcoin value broke US$11,000. Overnight, the crypto community has got rid of the March 12 nightmare, as if it had regained the bull market in 2017.

Network effect doesn't explain Bitcoin dominance : technical arguments for Bitcoin Maximalism

I often saw some Bitcoiners counter the altcoin shillers with the following argument: "Bitcoin is the first so it has the network effect, so your altcoin will always worth less"
This is not totally wrong but I think this argument is bad. Using it implies implicitly that you admit that Bitcoin is technically less capable than altcoins with their higher transaction rate, fast blocks, instant confirmation, without fees and smart contract support....

And this is WRONG ! Bitcoin price is higher, because Bitcoin is already TECHNICALLY BETTER than any other altcoin and not because of network effect. In 2017, Bitcoin dominance was lower, some altcoin reaches almost the same level than Bitcoin. So network effect is not what prevents an altcoin to take the lead but it is the fact that almost all altcoin that pretend to be better than Bitcoin are technically flawed.
Why ? They use bigger blocks, DAGs (Directed Acyclic Graphs, like used in IOTA or Nano) or wtf they created to disturbe you and make you believe they are better than the good old Bitcoin blockchain. But they have at least one of these two weak points: validation time oand bandwidth.

If they use biggefaster blocks, validation time of block is higher and so block propagation is slower. Less nodes can operate as they may not be able to validate blocks fast enough to keep up with the tip of the chain. You end up like Ethereum that has less and less full verification nodes leading to centralization of the network.
If they use DAGs, they achieve consensus through a "proof-of-stake" vote and always at the cost of bandwidth (quadratic cost in number of node, linear in transaction rate). DAGs are often presented as "each node has its own ledger" but the reality is that the only global ledger you should trust is the complete DAG of the ledgers of each node. Only servers with a shitload of download bandwidth can maintain it as debunked here and here. To not look (in fact be) centralized, some DAG altcoins doesn't, opening the door to history rewrite by buying account that owned a big stake before and still use a lot of bandwidth to reach consensus. Bitcoin just add 80 bytes of proof-of-work data on a block of 1-2MB to achieve it and protect from history rewrite, almost zero cost for the network (that's why we pay fees to miners who carry the cost).
You only have those problems when it reaches a critical level of usage and only then we can see how much those limits where ignored. Until now, very few altcoins reached the limit (maybe Ethereum, and IOTA shows us it is centralized already by stopping the network)
Bitcoin has the highest price because Bitcoin is technically the only possible decentralized king (and a centralized cryptocurrency worths nothing). Yes maybe 1MB limit was too conservativ, yes fees are higher, yes 10 minutes is slow. But if everyone wants their coffee payment to be settled onchain, 1MB or 8MB or 32MB each 10 minutes, minutes or secondes will never be enough while it is a big difference for the network health. You only need the blockchain for settlement, for payment you have Lightning Network that can already destroy PayPal's transaction rate.
So next time you feel convinced by an altcoin that pretend to be better than Bitcoin while being decentralized by design, evaluate the requirement to be a fully validating node and what the overhead of bandwidth needed to achieve consensus. The chances are high that they didn't take care of one of these two issues and end up centralized or broken. You don't need the network effect argument.

Satoshi Nakamoto and Bitcoin are not the only contents in Blockchain, This public chain which is possible modifying global finance trending is the "brave wind and waves" for DeFi

DEFI is extending rapidly, Market value is skyrocketing
Every single employee and employer will be shocked by DeFi in Blockchain industry, There has not been a single concept existed can compare to DeFi since block chain technology created ,sparking the fire to spread through the whole block chain industry; Even the founder of Bitcoin and Blockchain Satoshi Nakamoto may not considered that the DeFi trending will exceed Bitcoin.
Defi has become the hot topic in Blockchain field since the beginning of 2019;DeFi is the abbreviation for Decentralized Finance, also called open finance, meaning to build decentralized contracts which belongs to open financial system. DeFi is dedicating to provide time free, space free financial activities to all the people, it is what we called decentralized finance.
In the current financial systems, all financial services are controlled or adjusted unitedly by centralized finance system, whether the basic function such as deposit and transfer, loan or derivatives transactions are monitored and distributed by centralized financial organizations; DeFi is hoping to build a transparent, addressable and inclusive P2P financial system, minimizing the trust risks, simplifying the transactions payment process, expanding transactions scenarios.
DeFi platform has 3 obvious advantages compare to traditional centralized financial systems.
1.Global financial services are applying broadly, allowing everyone getting financial services through internet or smart phones which based on decentralized financial system built-in blockchains, including all the services that current banks organizations provide.
2.Blockchain techniques have high openness characteristic, everyone has the right to access, but nobody has central control right, achieving decentralizing for financial transactions. This point is the original purpose for creating Bitcoin by Satoshi Nakamoto.
3.Cross border will be more convenient and more economical. DeFi is applying the openness trait in Blockchain, avoiding expensive commission during global payment, allowing financial transaction to be more convenient, efficient when minimizing the global transferring cost.
Due to these benefits, DeFi is able to occupy first place at the triennial palace examination for block chain industries because of the benefits above. Capitalist is taking up the positions of the fallen and rising to fight one after another; According to the data within block chain fields on Aug 20, the market value for the whole DeFi industry is reaching 11.3billion dollars, which is the signal for passing the top digital currency industry; at the meantime, all the transactions are reaching 429million dollars in all decentralized exchanges; The total loan is reaching 1.5 billion on loan platform; The fixed asset is reaching 6.37billion dollar value for DeFi.
For global depressed economic, DeFi industry capital is exceeding most financial industries. When the river rises, the boat floats high. DeFi related project is gaining large profits in the vigorous blockchain exploitation processes. Token price is skyrocketing in DeFi. In two years, Total value DeFi project is rising to 10billion or more, From reasonable perspective, The whole DeFi ecosystem is filling with industry bubble, which is missing the flexibility and grounded projects.
Superior projects have something in common.
The so-called decentralized finance in DeFi, It consists two parts, which are decentralization and finance, under current circumstances, most projects only achieve “Financial “part in the industry, real decentralizing has not been achieved; For most DeFi projects, the first customized version was not satisfied the marketing expectations, most core functions will need to be updated, so the initial team has to have complete authority to control the projects in order to complete on-time and efficiency updating jobs.
This means that all the DeFi projects we see, most projects are controlled by initial creating team. Is controlled DeFi belongs to real DeFi? Does any single project can achieve Finance +decentralized?
New born AITD may satisfied blockchain expectation for DEFI, AITD Blockchain new generation foundation public chain at business level is built for “Decentralization +Finance.
As the marketing needs increasing annually for finance industries, such as banks, insurances, securities. AITD is following the trend closely, connecting the idea and purpose of DeFi, building a healthy, complete decentralized financial ecosystem; Blockchain DeFi+AITD are extending to new direction for insurance, Trust, pledge, cross region payment.
INSURANCE: AITD is innovating the current medical system by integrating insurance easy use scenarios, let’s using medical insurance as an example. AITD blockchain is not only storing digital information prove to blocks, but also achieving message sharing; AITD is able to break through the each steps in insurance process, solving asymmetry problem, allowing information transparency during insurance process for upstream and downstream, achieving value flows; Providing the rewarding mechanism for information provider through information sharing, leading medical system information publicized, breaking through each circulation for Medical- insurance-monitoring, realizing medical electronic and electronic insurance business, achieving insurance business stored in block chain networks through blockchain smart contract, achieving auto insurance verification, intelligent insurance claiming goal.
PLEDGE The essence of Pledge is new Smart business, as a new model are becoming the main track for real application, achieving to be the solid foundation for decentralized finance. Financial services should not be built under opacity lonely island. AITD is dedicating to build a finance system that allows everyone visiting as long as internet is available, letting value flow freely; According to the high intelligence and high transparency characteristic, AITD will bring new revolutionized storm to global financial system. The transforming direction for Pledge is open finance, open finance is the future morphology for finance. In the future, we are building highly ecological operating systems, fully integrating the innovative characteristics for front technology, smart business, open organization, digitalized finance, forming delicate business system.
TRUST: which is connecting block chain techniques is incorporating innovation, freedom, equality gene.In the premise of Justice and fair, Block chain Trust is containing market value maintaining promotion system, which is able to observe the instant experiences feedbacks for global users through constant updating, promoting changes for products, perfecting uses experiences’ .AITD collective Trust has high transparency rate, requiring real name authentication for loan corporation and investors themselves, processing transparency for each project’s process, dedicating to build a safe, stable, transparent, efficient online and offline platforms for medium , small, micro sized companies which have capital demand and person who has financing needs; innovating the traditional Trust operation mode, practicing facilitating health industry through technology, applying assets operation idea of integrating “smart” ”capital” idea, collaborating with medical fields experts who made great contributions in this field;dedicating to facilitate medical resources, medical research abilities and financial capitals high efficiency integration.
CROSS REGION PAYMENTS: Block chain payment techniques are changing “traditional assets flow and information flow” operation modes through the structure and improving traditional high cost transferring, low transparency rate, transactions risks through unique advantages of block chains; AITD has comprehensive, strong international bank card fund collecting products and diverse overseas or local payment receiving methods, which are able to provide global one station online payment solution proposals, allowing users to transfer from anywhere, anytime in the world, enabling merchant to accept different kinds of payments habits, processing exchange rate payment automatically; According to cross region payment scenarios, transferring speed and low cost advantages will be concentrated, platform will collaborate with other platforms within the globe, assisting these platforms which have global community backgrounds to explore payment channels.
AITD is incorporating block chain technology and finance to the maximum level. In the original thoughts of Bitcoin from Satoshi Nakamoto,counting on Bitcoin to modify the current financial system mode, allowing real freedom for currency, open sources, decentralization, flowing throughout the society and applying, creating multiple finance scenarios Trust Consensus; AITD+DeFi can achieve things that bitcoin cannot achieve.
AITD advantages, self-owned public chain
Traditional DeFi projects are distributed on the Ethereum or other networks, traffic jam, low experience rate, high processing fee, internet jam, resisting developer and so on, DeFi projects is suggesting user and developer quitting in Ethereum; AITD which belongs to DeFi is facing the same problems, but AITD team has already found the best solution for this problem. We will explain it later.
The current situation that DeFi industries are facing:Although there are too much complaining towards Ethereum, the new or old projects cannot kept without Ethereum. According to the DeFi prime data, in 242 DeFi projects that collecting one time, 197 numbers of DeFi are deployed on Ethereum, EOS and Bitcoin only contain 22 and 23 , DeFi project number is approaching to zero on other public chains, Ethereum is considering as the second leading factor for blockchain industries after Bitcoin, determining the fate of DeFi.
Why are DeFi (such as hot Compound, Uniswap) not existing in other public chains? Ultimately, the reason for public chains hardly generate Defi (except Ethereum) due to the following 3 reasons.
1).Public chain which considers Ethereum as the first public chain, possessing competitive advantages in kinds of assets, total number of assets.
2) Unlike Ethereum, other public chains are not paying much attention to DeFi. they are losing the initiation for following the trend now
3) DeFi Decentralization governing after scaling, causing costs for moving Ethereum to other public chain are hard to estimate.
Actually, after DeFi shocked digital currency encrypted market, each public chain is entering DeFi military prepared competition, capital, techniques, human resources are constantly devoting into DeFi; Finally, there is no single public chain exceeding Ethereum or challenging Ethereum.Pulic chain problems are the pain points for the industry.
Ether researcher once said that “According to the jam in Ether network, even worse than ICO bubble, this is not exaggerated, During the prosperous period for ICO in 2018, Each transaction processing fee is reaching 5.4 US dollars. However, at the 5:00pm in Aug 13th , this number is skyrocketing and reaching 7.4 us dollars, It is 15 times high comparing to 0.5 US dollars in the previous month;DeFi prosperity on Ether is marketing behavior which is against humanity.
Under this circumstances, the trend for searching new public chain is necessary; what is the AITD team solution? The answer is public chain
To avoid anti humanity sanction by Ether public chain and also to build a complete, efficient DeFi ecosystem. AITD team is researching and developing self-owned public chain in block chain for three years, providing multi block chain scenarios services to large user groups on AITD block chain.
In the future,AITD will provide reliable, safe, convenient blockchain services to users in basic public information search, copyright administration, tracing for certified products, ensuring product security scenarios, achieving multi-path communication which Bitcoin is not able to process; Meanwhile, AITD chain is achieving self-closing loop for ecosystem, extending the spirit of DeFi to insurance, Trust, Pledge,Cross border payment etc in multiple financial scenarios, achieving decentralized finance for real.
Current block chain network is independent internet relatively, encountering information island problems; Isolation of the internet is not supporting collaborative operation between each blockchain network. Isolation limit applied fields for the blockchain techniques at maximum level; However, AITD is dedicating to build a strong extensibility block chain networks, when it achieves fast, safe cross chain data visit, it also builds a valuable internet for the whole block chain industry.
Valued internet+ Blockchain decentralized finance, AITD have strong ambition, dedicating to provide value of 11.3billion the best application in financial world, we will wait for the expecting result.

The best DApps, which will likely lead the next phase.

The best DApps, which will likely lead the next phase.
Author: Gamals Ahmed, Business Ambassador
One of the key themes in 2020 is the rise of decentralized financing (DeFi), a new type of financing that works on decentralized protocols and without the need for financial intermediaries. Lately, the number of DeFi apps has increased significantly, but many have not been seen or heard by many of us.
In this Article I will be building a list of the best DApps, which will likely lead the next phase. DeFi apps can be categorized into different subcategories such as:
  • Finance
  • Exchange
  • Insurance
  • Gambling
  • Social
And much more…
Note: Some of the projects in the report categorized into more than one section in the types of dApps.
The rise of DeFi Bitcoin (BTC) was the first implementation of decentralized financing. It enabled individuals to conduct financial transactions with other individuals without the need for a financial intermediary in the digital age. Bitcoin and similar cryptocurrencies were the first wave of DeFi. The second wave of DeFi was enabled by Ethereum blockchain which added another layer of programmability to the blockchain. Now, at the beginning of 2020, individuals and companies can borrow, lend, trade, invest, exchange and store crypto assets in an unreliable way. In 2020, we can expect the amount of money held in lending protocols to increase as long-term investors diversify into interest-bearing offers, especially if the market fails to rise towards the 2017/18 highs. On the other hand, active crypto traders are becoming increasingly interested in decentralized trading offers. The increasing level of money security offered by decentralized trading platforms should not only see an increase in trading of DApp users, but also in the number of non-custodial trading and exchange platforms available.
Lending: DeFi allows anyone to obtain or provide a loan without third party approval. The vast majority of lending products use common cryptocurrencies such as Ether ($ ETH) to secure outstanding loans through over-collateral. Thanks to the emergence of smart contracts, maintenance margins and interest rates can be programmed directly into a borrowing agreement with liquidations occurring automatically if the account balance falls below the specified collateral. The relative benefit gained from supplying different cryptocurrencies is different for the asset and the underlying platform used.


Compound is a money market protocol on the Ethereum blockchain — allowing individuals, institutions, and applications to frictionlessly earn interest on or borrow cryptographic assets without having to negotiate with a counterparty or peer. Each market has a dynamic borrowing interest rate, which floats in real-time as market conditions adjust. Compound focuses on allowing borrowers to take out loans and lenders to provide loans by locking their crypto assets into the protocol. The interest rates paid and received by borrowers and lenders are determined by the supply and demand of each crypto asset. Interest rates are generated with every block mined. Loans can be paid back and locked assets can be withdrawn at any time. While DeFi may seem overwhelming complex to the average individual, Compound prides itself on building a product that is digestible for users of all backgrounds. Compound is a protocol on the Ethereum blockchain that establishes money markets, which are pools of assets with algorithmically derived interest rates, based on the supply and demand for the asset. Suppliers (and borrowers) of an asset interact directly with the protocol, earning (and paying) a floating interest rate, without having to negotiate terms such as maturity, interest rate, or collateral with a peer or counterparty. Built on top of that principle is cTokens, Compound’s native token that allows users to earn interest on their money while also being able to transfer, trade, and use that money in other applications. OVERVIEW ABOUT COMPOUND PROTOCOL Compound Finance is a San Francisco based company, which raised an $8.2 M seed round in May of 2018, and a $25M Series A round in November of 2019. Financing rounds were lead by industry giants including but not limited to Andressen Horowitz, Polychain Capital, Coinbase Ventures and Bain Capital Ventures, Compound Finance is a sector-leading lending protocol enabling users to lend and borrow popular cryptocurrencies like Ether, Dai and Tether. Compound leverages audited smart contracts responsible for the storage, management, and facilitation of all pooled capital. Users connect to Compound through web3 wallets like MetaMask with all positions being tracked using interest-earning tokens called cTokens.
Compound recently introduced a governance token — COMP. It holds no economic benefits and is solely used to vote on protocol proposals. The distribution of COMP has absolutely exceeded expectations on all fronts. Compound is now the leading DeFi protocol both in terms of Total Value Locked and in terms of COMP’s marketcap relative to other DeFi tokens. COMP was recently listed on Coinbase — the leading US cryptocurrency exchange and has seen strong interest from dozens of other exchanges including futures platforms like FTX. Compound’s new governance system is well underway, with close to close to 10 proposals being passed since it’s launch. What’s unique about COMP’s governance model is that tokenholders can delegate their tokens to an address of their choice. Only those who hold more than 1% of the supply can make new proposals. Besides earning interest on your crypto assets, which is a straightforward process of depositing crypto assets on the platform and receiving cTokens, you can also borrow crypto on Compound. Borrowing crypto assets has the added step of making sure the value of your collateral stays above a minimum amount relative to your loan. Compound and DeFi more broadly wants to help people have more access and control over the money they earn and save. While the project has had its criticisms, the long-term goal of Compound has always been to become fully decentralized over time. The Compound team currently manages the protocol, but they plan to eventually transfer all authority over to a Decentralized Autonomous Organization (DAO) governed by the Compound community. For following the project:
DEXs: Decentralized exchanges allow users to switch their assets without the need to transfer custody of basic collateral. DEXs aim to provide unreliable and interoperable trading across a wide range of trading pairs.


Kyber is a blockchain-based liquidity protocol that allows decentralized token swaps to be integrated into any application, enabling value exchange to be performed seamlessly between all parties in the ecosystem. Using this protocol, developers can build innovative payment flows and applications, including instant token swap services, ERC20 payments, and financial DApps helping to build a world where any token is usable anywhere. Kyber’s ecosystem is growing rapidly. In about a month, the team got an investment and partnered with some of the best projects. ParaFi Capital, a blockchain-focused investment company, has made a strategic purchase of KNC codes. The company will assist the DeFi project by qualifying new clients and improving professional market manufacture. The project’s recent partnerships seem impressive. Includes Chainlink, Chicago DeFi Alliance, and Digifox Wallet.
An important DeFi integration was also made with MakerDAO. KNC can now be used as a DAI warranty. The project has reached a milestone worth $ 1 billion of total turnover since its inception. More importantly, volume on an annual basis is moving and accelerating from $ 70 million in the first year to more than $ 600 million in 2020. Recently five million KNC (about 2.4% of total supply) were burned, improving Kyber’s supply and demand ratio. In July, the Kyber network witnessed a Katalyst upgrade that will improve governance, signature, delegation and structural improvements.
When Katalyst hits the main network, users will be able to either vote directly or delegate tokens to shareholder groups led by either companies like Stake Capital or community members. The KNC used to vote is burned, and in turn, voters get ETH as a reward. This setting creates a model for staking an uncommon contraction for the Kyber network. KyberDAO will facilitate chain governance, like many other projects based on Ethereum. An interesting partnership with xToken has been set up to help less-participating users stake out via xKNC. xKNC automatically makes specific voting decisions, making it easier for users to join and enjoy the return. The pool was created to draw BTC to Curve. Users who do this are eligible for returns in SNX, REN, CRV, and BAL. The more BTC lock on Synthetix, the more liquid it becomes, and the more attractive it is for traders. The project plans to continue expanding its products and move towards more decentralization. Synthetix futures are scheduled to appear on the exchange within a few months. The initial leverage is expected to be 10 to 20 times. The team aims to neglect its central oracle and replace it with one from Chainlink during the second stage of the migration. This will significantly increase the decentralization and flexibility of the platform. For following the project:
Derivatives: In traditional finance, a derivative represents a contract where the value is derived from an agreement based on the performance of an underlying asset. There are four main types of derivative contracts: futures, forwards, options, and swaps.


Synthetix is a decentralized artificial asset issuance protocol based on Ethereum. These synthetic assets are guaranteed by the Synthetix Network (SNX) code which enables, upon conclusion of the contract, the release of Synths. This combined collateral model allows users to make transfers between Compound directly with the smart contract, avoiding the need for counterparties. This mechanism solves DEX’s liquidity and sliding issues. Synthetix currently supports artificial banknotes, cryptocurrencies (long and short) and commodities.
SNX holders are encouraged to share their tokens as part of their proportionate percentage of activity fees are paid on Synthetix.Exchange, based on their contribution to the network. It contains three DApp applications for trading, signature and analysis: Exchange (Synths at no cost). Mintr (SNX lock for tuning and fee collection). Synthetix Network Token is a great platform in the ethereum ecosystem that leverages blockchain technology to help bridge the gap between the often mysterious cryptocurrency world and the more realistic world of traditional assets. That is, on the Synthetix network, there are Synths, which are artificial assets that provide exposure to assets such as gold, bitcoin, US dollars, and various stocks such as Tesla (NASDAQ: TSLA) and Apple (NASDAQ: AAPL). The whole idea of these artificial assets is to create shared assets where users benefit from exposure to the assets, without actually owning the asset.
It is a very unique idea, and a promising project in the ethereum landscape. Since it helps bridge the gap between cryptocurrencies and traditional assets, it creates a level of familiarity and value that is often lost in the assets of other digital currencies. This will make Synthetix take his seat in the next stage. On June 15, BitGo announced support for SNX and on June 19, Synthetix announced via blog post that Synthetix, Curve, and Ren “collaborated to launch a new stimulus group to provide liquidity for premium bitcoin on Ethereum”, and said the goal was to “create the most liquid Ethereum — the BTC-based suite available to provide traders with the lowest slippage” In trade between sBTC, renBTC and WBTC. “ For following the project:
Wallets: Wallets are a crucial gateway for interacting with DeFi products. While they commonly vary in their underlying product and asset support, across the board we’ve seen drastic improvements in usability and access thanks to the growing DeFi narrative.


It is the startup for consumer game-changing financial technology, which makes decentralized web access safer and easier. The company has built a smart and easy-to-use mobile wallet for Ethereum, which gives users the ability to easily retrieve their encrypted currencies on the go.
Argent Benefits:
  • Only you control your assets
  • Explore DeFi with one click
  • Easily retrieve and close your wallet
  • The wallet pays gas for in-app features, for example Compound and Maker
The Argent crypto wallet simplifies the process without sacrificing security. It is a type of wallet that allows you to keep cryptographic keys while keeping things simple. The Argent wallet is secured by something called the Guardians. If you lose your phone (and your Argent wallet), just contact your guardians to confirm your identity. Then you can get all your money back on another device. It is a simple and intuitive method that can make cryptocurrency manipulation easier to do without experience. Argent is focused on the Ethereum blockchain and plans to support everything Ethereum has to offer. Of course, you can send and receive ETH. The startup wants to hide the complexity on this front, as it covers transaction fees (gas) for you and gives you usernames. This way, you don’t have to set a transaction fee to make sure it expires. Insurance cooperative Nexus Mutual and Argent Portfolio Provider are planning to offer a range of smart and insurance contracts to keep Argent user money safe from hackers. First, the smart contract is designed to prevent thieves from draining the wallet by temporarily freezing transfers above the daily spending limit for addresses not listed in the user’s whitelist. The user has 24 hours to cancel the frozen transfer — very similar to the bank’s intervention and prevent fraud on the card or similar suspicious activities in the account. By contrast, the default coding state is closer to criticism: once it disappears, it disappears. “We are thinking not only of crypto users but also new users — so the ultimate goal is to duplicate what they get from their bank,” said Itamar Lisuis, one of the founders of Argent. For following the project:
Asset Management: With such a vast amount of DeFi products, it’s crucial that tools are in place to better track and manage assets. In line with the permissionless nature of the wider DeFi ecosystem, these assets management projects provide users with the ability to seamlessly track their balances across various tokens, products and services in an intuitive fashion.


It is a smart wallet for DeFi that allows users to seamlessly manage multiple DeFi applications to maximize returns across different protocols in a fraction of the time. With InstaDapp, users can take advantage of industry-leading projects like Compound, MakerDAO and Uniswap in one easy-to-use portal. Instadapp currently supports dapps MakerDAO and Compound DeFi, allowing users to add collateral, borrow, redeem and redeem their collateral on each dapp, as well as refinance debt positions between the two. In addition to its ease of use, InstaDapp also adds additional benefits and use cases for supported projects that are not already supported. The project focuses on making DeFi easier for non-technical users by maintaining a decentralized spirit while stripping many of the confusing terms that many products bring with them.
InstaDapp has launched a one-click and one-transaction solution that allows users to quadruple the COMP Codes they can earn from using quadruple borrowing and lending. A good timing feature for sure, but this kind of simplification is exactly why Instadapp was created. Its goal is to create a simple interface into multiple DeFi applications running on the Ethereum Blockchain and then automate complex interactions in a way that enables users to maximize their profits while reducing transactions and Ethereum gas charges. To use Instadapp you will need Ethereum wallet and you will also have to create what is called Instadapp smart wallet in which token you want to use. For following the project:
Savings: There are a select few DeFi projects which offer unique and novel ways to earn a return by saving cryptocurrencies. This differs from lending as there is no borrower on the other side of the table.


Dharma is an easy-to-use layer above the compound protocol. It introduces new and non-technical users to transaction encryption and allows them to easily borrow or lend in DeFi markets and earn interest in stable currencies. You can start by simply using a debit card. Funds are kept in a non-portfolio portfolio, which constantly earns interest on all of your deposited assets. The value of Dharma’s DeFi lending experience is:
  • Easy entry.
  • Simple wallet.
  • High protection.
  • Depositing and withdrawing banknotes.
Dharma, the prominent DeFi cryptobank bank, has made it extremely easy to bring any Twitter user into the crypto world. Dharma users can send money from the Dharma app by searching for any Twitter handle, setting the required amount, and clicking on one button. The Twitter Dharma Bot account can send a unique notification with a link to download the Dharma mobile app. Senders are encouraged to retweet the notification to ensure that the receiver does not lose it.
To raise money, recipients simply download the Dharma app. After creating a Dharma account, users connect their Twitter account to receive access to the money sent. They can choose to transfer money to US dollars and withdraw to a bank account, or leave DAI in a Dharma account where it will earn interest like all Dharma deposits. The submitted DAI will gain interest even before the receiving user requests it while waiting for the claim. In her ad, Dharma demonstrated a number of ways in which the new social payments feature can be used, including tips for your favorite Twitter personalities, accepting payments for goods or services in a very clear way, charitable donations across borders or transfer payments. The Dharma app is available for both Android and iOS. Dharma and Compound
Dharma generates interest by DAI signing the Compound Protocol. Dharma also appeared in the news recently after the release of a specification outlining a Layer 2 expansion solution allowing the platform to expand to handle current transaction volume 10x, ensuring users can transfer their money quickly even in times of heavy congestion on the Ethereum network. Dharma is developing its “core” and “underwriting” contracts within the company. Underwriting contracts are open source and non-custodian, while each loan contract is closed source. This means that the receiving address contains nodes that interact with a script on a central Dharma server.For following the project:
Insurance: Decentralized insurance protocols allow users to take out policies on smart contracts, funds, or any other cryptocurrencies through pooled funds and reserves.

Nexus Mutual

Nexus Mutual uses blockchain technology to return mutual values to insurance by creating consistent incentives with the smart contract symbol on the Ethereum blockchain. It is built on the Ethchaum blockchain and uses a modular system to aggregate smart Ethereum nodes, allowing to upgrade the system’s logical components without affecting other components.
The way Nexus works is members of the mutual association by purchasing NXM codes that allow them to participate in the decentralized independent organization (DAO). All decisions are voted on by members, who are motivated to pay real claims. It sees plenty of opportunities in a gradual transition of Ethereum to Eth 2.0, which is expected to start later this year. Eth 2.0 moves the network from the power-hungry Proof-of-Consensus (PoW) algorithm to Proof-of-Stake (PoS), a way to sign cryptocurrency in order to keep the network afloat. Having a steady return on signature from the Ether (ETH) can be somewhat compared to the way in which insurance companies invest in the real world the premiums they collect.
By setting a strong set of conditions for Nexus Mutual, anyone will be able to bring in and acquire a new form of risk for mutual coverage — assuming that members are willing to share NXM. With this design, the mutual discretion will be able to expand into much broader fields beyond smart contracts. In addition to defining multi-layered term agreements, Nexus Mutual also has some other advantages needed to achieve this visualization. For following the project:
