An In-Depth Guide to: How do I Fix my Ledger Nano’s Stuck Ethereum Transaction?!?!?! (It’s Been Stuck for Weeks and NOTHING Traditional has Worked!!!!) As Well as: How Do I Choose My Nonce??? I’ve Tried MetaMask, MEW/MyEtherWallet, and Others, but Nothing is Working Correctly!!! I’m Dying by Stress!

So, if you were like me 1-2 months ago, you’ve probably already gone through 2,or 3, ...or 40 articles and guides that probably say something like:
“YeP, eVeRy EtHeReUm UsEr WiLl EvEnTuAlLy HaVe ThE LoW-gAs ExPeRiEnCe, YoU’rE nOt AlOnE! DoN’t FrEaK OuT tHoUgH; ThErE iS a WaY tO fIx It!”
Chances are, every time you read another useless article, you want to kill the nearest inanimate object, even though it was never alive in the first place. Nonetheless, you’re gonna kill it as much as it can be killed, holding nothing back; or, you’re just plotting to and slowly getting closer to executing the plan (and the object) every time you are insulted once again.
However, if you have the ability to download software (MyCryptoWallet) on a PC, it should be safe to relax now. I think you’ve finally found some good news, because I am 99.99...% sure this will work for the issue that so many people are having at this time, around the end of the month of May, year 2020.
More and more people are likely to be having this issue soon, since Ethereum's gas prices have been insanely high lately as well as having 300% price changes in a matter of minutes; Etherscan’s Gas tracker is nearly uselessly-inaccurate at this time. I've heard that there's a congestion attack; that was said a week ago, and it appears to be ongoing... (I can't think of any other suspect besides Justin Sun to blame it on... it must be incredibly expensive to overload the blockchain for this long... I may be wrong though...)
 
Let’s begin
For myself, I was trying to send an ERC20 token when this dreadful issue attacked. Specifically, the token was either BSOV or GRT; I sent them 1 after the other and the first succeeded, and the second one took over a week.
(They’re both great tokens in my opinion and deserve much more attention than they’ve been getting. BSOV is nearing its 1 year anniversary as I write this, and GRT is still in its 90 day community-development progress test, so of course I'm gonna take this opportunity to "shill" them; they are great tokens with great communities).
I was able to finally fix it, after a week of mental agony (also the txn finally processed 1-2 hours before I found the solution, robbing me of the gratitude of fixing it myself... (╯‵□′)╯︵┻━┻ ...but now I guess I can hopefully save some of you the headaches that I endured... ) I’m providing the ability to do the same, in a step by step guide.
Why did I go through all of this trouble? I'd fault the fact that I have ADHD and autism, which in my case can multiply each other’s intensity and cause me to “hyper-focus” on things, much much more than most with the same qualities, intentionally or not. Adderall is supposed to give me a bit of control over it, but except for in a very-generalized way, it’s still 90% up to chance and my default-capabilities to allow me control over my attention with self-willpower. But also Karma and Moons pls... ʘ‿ʘ
 
  1. In MyCrypto, (I'm using the Windows 10 app, version 1.7.10) you will open to a screen that says "How would you like to access your wallet?". Choose Ledger, of course. (Unless your here for some non-ledger issue? Idk why you would be but ok.)
  2. On the next screen (having your nano already plugged in, unlocked, and opened into the Ethereum app) click "Connect to Ledger Wallet"
  3. A screen overlay should appear, titled: "Select an Address". Here is where it may get confusing for some users. Refer to "AAA" below to know how to find your account. (Geez, sorry lol that was a huge amount of info for a reddit reply; I might've over-elaborated a little bit too much. but hey it's valuable information nonetheless!)
  4. After escaping the "AAA" section, you'll have accessed your account with MyCrypto. Awesome! To find your ERC20 tokens, (slight evil-laughter is heard from an unidentifiable origin somewhere in the back of your mind) go to "AAB".
  5. (You may have decided to find the token(s) on your own, rather than daring to submit to my help again; if so, you may pity those who chose the other path... ~~( ̄▽ ̄)~~) Now, once you've added your token, you should revert your attention to the account's transfer fill-out form!
  6. I'll combine the steps you probably understood on your own, already. Put in the address that your stuck transaction is still trying to send currency to. If an ERC20 token is involved, use the drop-down menu to change "ETH" to the token in trouble. Input your amount into the box labeled... wait for it... "Amount". Click on "+Advanced".
  7. Refer to Etherscan.com for the data you will need. Find the page for your "transaction(txn) hash/address" from the transaction history on the wallet/Ethereum-manager you used to send from. If that is unavailable, put your public address that your txn was sent from into the search tool and go to its info page; you should be able to find the pending txn there. Look to open the "more details" option to find the transaction's "Nonce" number.
  8. Put the nonce in the "Nonce" box on MyCrypto; you will contest the pending txn with a new txn that offers larger gas fees, by using the same nonce. If (but most likely "When") the new transaction is processed first, for being more miner-beneficial, the nonce will then be completed, and the old transaction will be dropped because it requests an invalid, now-outdated nonce. Your account will soon be usable!
  9. Go to the Gas Tracker, and it may or may not provide an informative reading. Choose whatever amount you think is best, but choose wisely; if you're too stingy it may get stuck again, and you'd need to pay another txn's gas to attempt another txn-fix.
  10. At the time I write this, I'd recommend 50-100 gwei; to repeat myself, gas requirements are insane right now. To be safe, make the gas limit a little higher than MCW's automatic calculation, you may need to undo the check-mark for "Automatically Calculate Gas Limit".
  11. Press "Send Transaction"!!!
  12. You will need to validate the action through your nano. It will have you validate three different things if you are moving an ERC20 Token. It's a good idea to verify accuracy, as always.
 
Well, I hope this worked for you! If not, you can let me know in a reply and I'll try to figure it out with you. I like making these in-depth educational posts, so if you appreciate it please let me know; I'll probably make more posts like this in the future!
( Surely this is at least far better than Ledger's "Support" article where they basically just tell you "Yeah, we haven't bothered to make a way to manually select nonces. I guess we might try to make that available for Bitcoin accounts at some point in the future; who knows? lol"... that's not infuriating at all, right?)
 
AAA:
Before I tell you how to find your address, I will first make it clear, within the italicized text, exactly which address you are looking for, if you are not already sure:
You may also skip the text written in italics if your issue does not include an ERC20 token, if you wish.
Ledger Live can confuse some users with its interface. On LL, to manage an ERC20 token, you first must go to your Ethereum account and add the token. When you then click on the added token under "Tokens" below the graph chart for your account's ETH amount over time, the screen will then open a new screen, that looks just the same, except focused on the specific ERC20 token. To confuse users further, there is then an option to "Star account", which then add the ETH icon with the ERC20 token's first letter or symbol overlapping, onto the easy access sidebar, as if it was another account of similar independency to the ETH account it was added to.
This improperly displays the two "accounts" relation to each other.
Your ERC20 holdings (at least for any and all ERC20 that I know of) are "held" in the exact-same address as the Ethereum address it was added to, which also "holds" any Ether you've added to it. You send both Ether (ETH) and any ERC20 Tokens to and from only Ethereum addresses of equivalent capabilities, in both qualities and quantities. In all basic terms and uses, they are the same.
So, to know what the problematic account's address is, find the address of the Ethereum account it was added to in Ledger Live.
Now, to find your address on MyCrypto, the most reliable way to find it, that I am aware of, is this:
Open Ledger Live. Go to the screen of your Ethereum address (again, this is the one that you added your ERC20 token, if applicable. If you're not dealing with an ERC20 token, you may ignore everything I've put in Italics). Click on "Edit account"; this is the icon next to the star that may look like a hex-wrench tool. On the new screen-overlay, you will see "> ADVANCED LOGS". Click on the ">" and it will point down while revealing a drop-down with some data that you may or may not recognize/understand. Likely to be found indented and in the middle-ish area, you will see this line, or something hopefully similar:
"freshAddressPath": "44'/60'/X'/0/0",
The "X" will probably be the only thing that changes, and the actual data will have a number in its place; it will not be a letter. Let's now put that line to use in MyCrypto:
Take the 44'/60'/X'/0/0 , and make sure you DO NOT copy the quotation marks, or that comma at the end either.
You can do this before or after copying and/or pasting, but drop the second "/0" at the end; it was not necessary in my case, I expect that you won't need it either, and will probably just make MyCrypto see it as an invalid input.
Okay, now go back to the "Select an Address" screen-overlay in MyCrypto.
Next to "Addresses", click on the box on the right, and you should be shown a list of options to select from in a drop-down menu.
Scroll all the way down, and you should find the "Custom" option at the very bottom. Select it.
A new box will appear; probably directly to the right of the now-shortened box that now displays the "Custom" option that you just selected. This box will offer an interface for typed input. ...yep... once again, believe it or not, you should click it.
Type " m/ ", no spaces before or after.
Type in or paste the data we retrieved from ledger live.
The box should now hold this:
m/44'/60'/X'/0
Again, X should be a number. In fact, that number is probably equal to the number of Ethereum (not including any ERC20 wannabe) accounts that you've made on Ledger Live before making the one we're working on right now! (1st Eth. Acc. would have: X = 0, 2nd: X = 1, 3rd: X = 2, ...)
Make sure you've included every apostrophe ( ' ), and solidus ( / ); there is NO APOSTROPHE for the "m" at the start and the "/0" at the end!
If you press the enter key or click on the check-mark to the right of where you typed, the appropriate addresses will be generated, and the address you created through Ledger Live should be the first one on the list!
Select your address and press "Unlock", and you are now accessing your account through the MyCrypto app's interface!
 
AAB:
In order to access your ERC20 token, you will need to add them first.
You may have to scroll down, but on the right-side of your unlocked account screen, you'll see a box with "Token Balances" as its header.
Click "Scan for tokens". This may take a short bit of time, and when it's done it may or may not display your ERC20 token. If it worked, you can head on back to the main part.
If you got the result I did, it won't display your token, or, if our result was exactly the same, it won't display any at all. However, you should now have the "Add Custom Token" option available, so see where that takes you.
You should discover four boxes, specified in order (Address/ Decimals / Token_Symbol / Balance). You may only need to fill in the "Address" box, but if you need to fill others, you'll find those with the token's address; here's 2 ways to find it, if you don't already know.
Method I:
Since you've probably already been managing your token with Ledger Live, you can go to the LL screen of your "account" for that token; Right next to the account's icon, and directly above the name, you'll see:
Contract: 0x??????...????????
Yes, go on; click it. You'll find the token's page on Etherscan; this was just a shortcut to the same place that both of the two previously referenced methods lead to. Skip to method... III?
Method II:
Go to Etherscan.com, or a similar Ethereum-blockchain-monitoring website, if you have a different preference. Search for the name of your token, and you should be able to see it as a search result. Activate your search manually of by selecting search option. Continue on with Method III.
Method III (Iⅈ what makes you think there was a third method? I said 2!):
At this point, you should find the "contract address" somewhere on the screen. This is the identity of the creature that breathes life into the token, allowing it to exist within the world of Ethereum. Steal it, and tell MyCrypto that you've left some of "your" tokens in the address of your ledger's Ethereum account. MyCrypto will trust and believe you without any concern or doubt, just by putting "your" contract address in the box for "Address"; it's almost too easy!
Well whaddya know, this one isn't actually too long! Don't tell anyone who may have taken a little longer whilst finding out how to do it themselves, though. There's value in trying to do something on your own, at least at first, so I'll let them think they made the right choice (¬‿¬). But take this star for humbling yourself enough to seek further help when you need it, since that is a very important life skill as well!
(o゜▽゜)o☆
Now, back to the useful stuff at the top...
 
EDIT: A comment below made me realize that this info should be added too. Here is my reply to the comment saying I could just use MetaMask. I said in the title that this guide is for questions where MEW and MetaMask aren’t working, but I guess it’s easy to miss. I used my u/caddark account to respond:
(Using this account because u/caddarkcrypto doesn’t meet the karma/age standards to comment; the post had to be manually approved.)
I guess I didn’t make it entirely clear; sorry:
The target audience for this guide is anyone with a stuck Ethereum transaction that was initiated through Ledger Live AND are experiencing the same difficulties I had encountered while trying to fix this issue for myself.
This wasn’t any regular stuck Ethereum transaction. Apparently before, there was an issue that made a Ledger Nano nearly impossible to connect to MetaMask (which is also Brave Browser’s integrated “crypto wallet” for the desktop version) and/or MEW (also perhaps any other browser wallets made for chrome and/or brave) that I heard was supposed to be fixed in a recent update. It might’ve been mostly patched, idk, but during my experience, (in which I was using the latest version of Ledger Live that is available right now,) that issue still remained.
The really weird part was that it successfully connected to the browser wallets again after I fixed the stuck transaction. At first I thought that somehow the txn was what was bugging the connection. However, later, during no txn issues, I was again unable to connect.
Seeing the same connection error again later, I opened up the MCW app I downloaded the day before, and was going to just use that. While in the process of operating MCW, I suddenly had another idea to try for the browser wallet so I went back to that just to quickly test it.
The browser wallet worked perfectly...
I don’t know how, but I think that somehow, something in MCW’s software, makes the browser wallets work. They don’t work for me without having MCW opened in the background first.
EDIT 2: Markdown decided to stop working after I did the first edit... I might fix it tomorrow... how did that happen though??? What did I do?
EDIT 3: nvm, I'm just fixing it now; I won't get much sleep tonight I guess.

Filecoin | Development Status and Mining Progress

Author: Gamals Ahmed, CoinEx Business Ambassador
https://preview.redd.it/5bqakdqgl3g51.jpg?width=865&format=pjpg&auto=webp&s=b709794863977eb6554e3919b9e00ca750e3e704
A decentralized storage network that transforms cloud storage into an account market. Miners obtain the integrity of the original protocol by providing data storage and / or retrieval. On the contrary, customers pay miners to store or distribute data and retrieve it.
Filecoin announced, that there will be more delays before its main network is officially launched.
Filecoin developers postponed the release date of their main network to late July to late August 2020.
As mentioned in a recent announcement, the Filecoin team said that the initiative completed the first round of the internal protocol security audit. Platform developers claim that the results of the review showed that they need to make several changes to the protocol’s code base before performing the second stage of the software testing process.
Created by Protocol Labs, Filecoin was developed using File System (IPFS), which is a peer-to-peer data storage network. Filecoin will allow users to trade storage space in an open and decentralized market.
Filecoin developers implemented one of the largest cryptocurrency sales in 2017. They have privately obtained over $ 200 million from professional or accredited investors, including many institutional investors.
The main network was slated to launch last month, but in February 2020, the Philly Queen development team delayed the release of the main network between July 15 and July 17, 2020.
They claimed that the outbreak of the Coronavirus (COVID-19) in China was the main cause of the delay. The developers now say that they need more time to solve the problems found during a recent codecase audit.
The Filecoin team noted the following:
“We have drafted a number of protocol changes to ensure that building our major network launch is safe and economically sound.” The project developers will add them to two different implementations of Filecoin (Lotus and go-filecoin) in the coming weeks.
Filecoin developers conducted a survey to allow platform community members to cast their votes on three different launch dates for Testnet Phase 2 and mainnet.
The team reported that the community gave their votes. Based on the vote results, the Filecoin team announced a “conservative” estimate that the second phase of the network test should begin by May 11, 2020. The main Filecoin network may be launched sometime between July 20 and August 21, 2020.
The updates to the project can be found on the Filecoin Road Map.
Filecoin developers stated:
“This option will make us get the most important protocol changes first, and then implement the rest as protocol updates during testnet.” Filecoin is back down from the final test stage.
Another filecoin decentralized storage network provider launched its catalytic test network, the final stage of the storage network test that supports the blockchain.
In a blog post on her website, Filecoin said she will postpone the last test round until August. The company also announced a calibration period from July 20 to August 3 to allow miners to test their mining settings and get an idea of how competition conditions affected their rewards.
Filecoin had announced earlier last month that the catalytic testnet test would precede its flagship launch. The delay in the final test also means that the company has returned the main launch window between August 31 and September 21.
Despite the lack of clear incentives for miners and multiple delays, Filecoin has succeeded in attracting huge interest, especially in China. Investors remained highly speculating on the network’s mining hardware and its premium price.
Mining in Filecoin
In most blockchain protocols, “miners” are network participants who do the work necessary to promote and maintain the blockchain. To provide these services, miners are compensated in the original cryptocurrency.
Mining in Filecoin works completely differently — instead of contributing to computational power, miners contribute storage capacity to use for dealing with customers looking to store data.
Filecoin will contain several types of miners:
Storage miners responsible for storing files and data on the network. Miners retrieval, responsible for providing quick tubes for file recovery. Miners repair to be carried out.
Storage miners are the heart of the network. They earn Filecoin by storing data for clients, and computerizing cipher directories to check storage over time. The probability of earning the reward reward and transaction fees is proportional to the amount of storage that the Miner contributes to the Filecoin network, not the hash power.
Retriever miners are the veins of the network. They earn Filecoin by winning bids and mining fees for a specific file, which is determined by the market value of the said file size. Miners bandwidth and recovery / initial transaction response time will determine its ability to close recovery deals on the network.
The maximum bandwidth of the recovery miners will determine the total amount of deals that it can enter into.
In the current implementation, the focus is mostly on storage miners, who sell storage capacity for FIL.

Hardware recommendations

The current system specifications recommended for running the miner are:
Compared to the hardware requirements for running a validity checker, these standards are much higher — although they definitely deserve it. Since these will not increase in the presumed future, the money spent on Filecoin mining hardware will provide users with many years of reliable service, and they pay themselves many times. Think of investing as a small business for cloud storage. To launch a model on the current data hosting model, it will cost millions of dollars in infrastructure and logistics to get started. With Filecoin, you can do the same for a few thousand dollars.
Proceed to mining
Deals are the primary function of the Filecoin network, and it represents an agreement between a client and miners for a “storage” contract.
Once the customer decides to have a miner to store based on the available capacity, duration and price required, he secures sufficient funds in a linked portfolio to cover the total cost of the deal. The deal is then published once the mine accepts the storage agreement. By default, all Filecoin miners are set to automatically accept any deal that meets their criteria, although this can be disabled for miners who prefer to organize their deals manually.
After the deal is published, the customer prepares the data for storage and then transfers it to the miner. Upon receiving all the data, the miner fills in the data in a sector, closes it, and begins to provide proofs to the chain. Once the first confirmation is obtained, the customer can make sure the data is stored correctly, and the deal has officially started.
Throughout the deal, the miner provides continuous proofs to the chain. Clients gradually pay with money they previously closed. If there is missing or late evidence, the miner is punished. More information about this can be found in the Runtime, Cut and Penalties section of this page.
At Filecoin, miners earn two different types of rewards for their efforts: storage fees and reward prevention.
Storage fees are the fees that customers pay regularly after reaching a deal, in exchange for storing data. This fee is automatically deposited into the withdrawal portfolio associated with miners while they continue to perform their duties over time, and is locked for a short period upon receipt.
Block rewards are large sums given to miners calculated on a new block. Unlike storage fees, these rewards do not come from a linked customer; Instead, the new FIL “prints” the network as an inflationary and incentive measure for miners to develop the chain. All active miners on the network have a chance to get a block bonus, their chance to be directly proportional to the amount of storage space that is currently being contributed to the network.
Duration of operation, cutting and penalties
“Slashing” is a feature found in most blockchain protocols, and is used to punish miners who fail to provide reliable uptime or act maliciously against the network.
In Filecoin, miners are susceptible to two different types of cut: storage error cut, unanimously reduce error.
Storage Error Reduction is a term used to include a wider range of penalties, including error fees, sector penalties, and termination fees. Miners must pay these penalties if they fail to provide reliability of the sector or decide to leave the network voluntarily.
An error fee is a penalty that a miner incurs for each non-working day. Sector punishment: A penalty incurred by a miner of a disrupted sector for which no error was reported before the WindowPoSt inspection.
The sector will pay an error fee after the penalty of the sector once the error is discovered.
Termination Fee: A penalty that a miner incurs when a sector is voluntary or involuntarily terminated and removed from the network.
Cutting consensus error is the penalty that a miner incurs for committing consensus errors. This punishment applies to miners who have acted maliciously against the network consensus function.
Filecoin miners
Eight of the top 10 Felticoin miners are Chinese investors or companies, according to the blockchain explorer, while more companies are selling cloud mining contracts and distributed file sharing system hardware. CoinDesk’s Wolfe Chao wrote: “China’s craze for Filecoin may have been largely related to the long-standing popularity of crypto mining in the country overall, which is home to about 65% of the computing power on Bitcoin at discretion.”
With Filecoin approaching the launch of the mainnet blocknet — after several delays since the $ 200 million increase in 2017 — Chinese investors are once again speculating strongly about network mining devices and their premium prices.
Since Protocol Labs, the company behind Filecoin, released its “Test Incentives” program on June 9 that was scheduled to start in a week’s time, more than a dozen Chinese companies have started selling cloud mining contracts and hardware — despite important details such as economics Mining incentives on the main network are still endless.
Sales volumes to date for each of these companies can range from half a million to tens of millions of dollars, according to self-reported data on these platforms that CoinDesk has watched and interviews with several mining hardware manufacturers.
Filecoin’s goal is to build a distributed storage network with token rewards to spur storage hosting as a way to drive wider adoption. Protocol Labs launched a test network in December 2019. But the tokens mined in the testing environment so far are not representative of the true silicon coin that can be traded when the main network is turned on. Moreover, the mining incentive economics on testnet do not represent how final block rewards will be available on the main network.
However, data from Blockecoin’s blocknetin testnet explorers show that eight out of 10 miners with the most effective mining force on testnet are currently Chinese miners.
These eight miners have about 15 petabytes (PB) of effective storage mining power, accounting for more than 85% of the total test of 17.9 petable. For the context, 1 petabyte of hard disk storage = 1000 terabytes (terabytes) = 1 million gigabytes (GB).
Filecoin craze in China may be closely related to the long-standing popularity of crypt mining in the country overall, which is home to about 65% of the computing power on Bitcoin by estimation. In addition, there has been a lot of hype in China about foreign exchange mining since 2018, as companies promote all types of devices when the network is still in development.
“Encryption mining has always been popular in China,” said Andy Tien, co-founder of 1475, one of several mining hardware manufacturers in Philquin supported by prominent Chinese video indicators such as Fenbushi and Hashkey Capital.
“Even though the Velikoyen mining process is more technologically sophisticated, the idea of mining using hard drives instead of specialized machines like Bitcoin ASIC may be a lot easier for retailers to understand,” he said.
Meanwhile, according to Feixiaohao, a Chinese service comparable to CoinMarketCap, nearly 50 Chinese crypto exchanges are often somewhat unknown with some of the more well-known exchanges including Gate.io and Biki — have listed trading pairs for Filecoin currency contracts for USDT.
In bitcoin mining, at the current difficulty level, one segment per second (TH / s) fragmentation rate is expected to generate around 0.000008 BTC within 24 hours. The higher the number of TH / s, the greater the number of bitcoins it should be able to produce proportionately. But in Filecoin, the efficient mining force of miners depends on the amount of data stamped on the hard drive, not the total size of the hard drive.
To close data in the hard drive, the Filecoin miner still needs processing power, i.e. CPU or GPU as well as RAM. More powerful processors with improved software can confine data to the hard drive more quickly, so miners can combine more efficient mining energy faster on a given day.
As of this stage, there appears to be no transparent way at the network level for retail investors to see how much of the purchased hard disk drive was purchased which actually represents an effective mining force.
The U.S.-based Labs Protocol was behind Filecoin’s initial coin offer for 2017, which raised an astonishing $ 200 million.
This was in addition to a $ 50 million increase in private investment supported by notable venture capital projects including Sequoia, Anderson Horowitz and Union Square Ventures. CoinDk’s parent company, CoinDk, has also invested in Protocol Labs.
After rounds of delay, Protocol Protocols said in September 2019 that a testnet launch would be available around December 2019 and the main network would be rolled out in the first quarter of 2020.
The test started as promised, but the main network has been delayed again and is now expected to launch in August 2020. What is Filecoin mining process?
Filecoin mainly consists of three parts: the storage market (the chain), the blockecin Filecoin, and the search market (under the chain). Storage and research market in series and series respectively for security and efficiency. For users, the storage frequency is relatively low, and the security requirements are relatively high, so the storage process is placed on the chain. The retrieval frequency is much higher than the storage frequency when there is a certain amount of data. Given the performance problem in processing data on the chain, the retrieval process under the chain is performed. In order to solve the security issue of payment in the retrieval process, Filecoin adopts the micro-payment strategy. In simple terms, the process is to split the document into several copies, and every time the user gets a portion of the data, the corresponding fee is paid. Types of mines corresponding to Filecoin’s two major markets are miners and warehousers, among whom miners are primarily responsible for storing data and block packages, while miners are primarily responsible for data query. After the stable operation of the major Filecoin network in the future, the mining operator will be introduced, who is the main responsible for data maintenance.
In the initial release of Filecoin, the request matching mechanism was not implemented in the storage market and retrieval market, but the takeover mechanism was adopted. The three main parts of Filecoin correspond to three processes, namely the stored procedure, retrieval process, packaging and reward process. The following figure shows the simplified process and the income of the miners:
The Filecoin mining process is much more complicated, and the important factor in determining the previous mining profit is efficient storage. Effective storage is a key feature that distinguishes Filecoin from other decentralized storage projects. In Filecoin’s EC consensus, effective storage is similar to interest in PoS, which determines the likelihood that a miner will get the right to fill, that is, the proportion of miners effectively stored in the entire network is proportional to final mining revenue.
It is also possible to obtain higher effective storage under the same hardware conditions by improving the mining algorithm. However, the current increase in the number of benefits that can be achieved by improving the algorithm is still unknown.
It seeks to promote mining using Filecoin Discover
Filecoin announced Filecoin Discover — a step to encourage miners to join the Filecoin network. According to the company, Filecoin Discover is “an ever-growing catalog of numerous petabytes of public data covering literature, science, art, and history.” Miners interested in sharing can choose which data sets they want to store, and receive that data on a drive at a cost. In exchange for storing this verified data, miners will earn additional Filecoin above the regular block rewards for storing data. Includes the current catalog of open source data sets; ENCODE, 1000 Genomes, Project Gutenberg, Berkley Self-driving data, more projects, and datasets are added every day.
Ian Darrow, Head of Operations at Filecoin, commented on the announcement:
“Over 2.5 quintillion bytes of data are created every day. This data includes 294 billion emails, 500 million tweets and 64 billion messages on social media. But it is also climatology reports, disease tracking maps, connected vehicle coordinates and much more. It is extremely important that we maintain data that will serve as the backbone for future research and discovery”.
Miners who choose to participate in Filecoin Discover may receive hard drives pre-loaded with verified data, as well as setup and maintenance instructions, depending on the company. The Filecoin team will also host the Slack (fil-Discover-support) channel where miners can learn more.
Filecoin got its fair share of obstacles along the way. Last month Filecoin announced a further delay before its main network was officially launched — after years of raising funds.
In late July QEBR (OTC: QEBR) announced that it had ceded ownership of two subsidiaries in order to focus all of the company’s resources on building blockchain-based mining operations.
The QEBR technology team previously announced that it has proven its system as a Filecoin node valid with CPU, GPU, bandwidth and storage compatibility that meets all IPFS guidelines. The QEBR test system is connected to the main Filecoin blockchain and the already mined filecoin coin has already been tested.
“The disclosure of Sheen Boom and Jihye will allow our team to focus only on the upcoming global launch of Filecoin. QEBR branch, Shenzhen DZD Digital Technology Ltd. (“ DZD “), has a strong background in blockchain development, extraction Data, data acquisition, data processing, data technology research. We strongly believe Filecoin has the potential to be a leading blockchain-based cryptocurrency and will make every effort to make QEBR an important player when Mainecoin mainnet will be launched soon”.
IPFS and Filecoin
Filecoin and IPFS are complementary protocols for storing and sharing data in a decentralized network. While users are not required to use Filecoin and IPFS together, the two combined are working to resolve major failures in the current web infrastructure.
IPFS
It is an open source protocol that allows users to store and transmit verifiable data with each other. IPFS users insist on data on the network by installing it on their own device, to a third-party cloud service (known as Pinning Services), or through community-oriented systems where a group of individual IPFS users share resources to ensure the content stays live.
The lack of an integrated catalytic mechanism is the challenge Filecoin hopes to solve by allowing users to catalyze long-term distributed storage at competitive prices through the storage contract market, while maintaining the efficiency and flexibility that the IPFS network provides.
Using IPFS
In IPFS, the data is hosted by the required data installation nodes. For data to persist while the user node is offline, users must either rely on their other peers to install their data voluntarily or use a central install service to store data.
Peer-to-peer reliance caching data may be a good thing as one or multiple organizations share common files on an internal network, or where strong social contracts can be used to ensure continued hosting and preservation of content in the long run. Most users in an IPFS network use an installation service.
Using Filecoin
The last option is to install your data in a decentralized storage market, such as Filecoin. In Filecoin’s structure, customers make regular small payments to store data when a certain availability, while miners earn those payments by constantly checking the integrity of this data, storing it, and ensuring its quick recovery. This allows users to motivate Filecoin miners to ensure that their content will be live when it is needed, a distinct advantage of relying only on other network users as required using IPFS alone.
Filecoin, powered by IPFS
It is important to know that Filecoin is built on top of IPFS. Filecoin aims to be a very integrated and seamless storage market that takes advantage of the basic functions provided by IPFS, they are connected to each other, but can be implemented completely independently of each other. Users do not need to interact with Filecoin in order to use IPFS.
Some advantages of sharing Filecoin with IPFS:
Of all the decentralized storage projects, Filecoin is undoubtedly the most interested, and IPFS has been running stably for two years, fully demonstrating the strength of its core protocol.
Filecoin’s ability to obtain market share from traditional central storage depends on end-user experience and storage price. Currently, most Filecoin nodes are posted in the IDC room. Actual deployment and operation costs are not reduced compared to traditional central cloud storage, and the storage process is more complicated.
PoRep and PoSt, which has a large number of proofs of unknown operation, are required to cause the actual storage cost to be so, in the early days of the release of Filecoin. The actual cost of storing data may be higher than the cost of central cloud storage, but the initial storage node may reduce the storage price in order to obtain block rewards, which may result in the actual storage price lower than traditional central cloud storage.
In the long term, Filecoin still needs to take full advantage of its P2P storage, convert storage devices from specialization to civil use, and improve its algorithms to reduce storage costs without affecting user experience. The storage problem is an important problem to be solved in the blockchain field, so a large number of storage projects were presented at the 19th Web3 Summit. IPFS is an important part of Web3 visibility. Its development will affect the development of Web3 to some extent. Likewise, Web3 development somewhat determines the future of IPFS. Filecoin is an IPFS-based storage class project initiated by IPFS. There is no doubt that he is highly expected.

Actual cost of a 51% attach, $10.2 million

So I was discussing this last week and honestly it all felt too simple, so I'm trying to get some stronger counterpoints to this argument. Goes something like this.
You have some pool miner that wants to do a 51% attack. Lets assume the attack has three phases, the first phase is to try to accumulate 51% of the hashing power, next is the accumulation of more hashing power by ejecting other pools from through reorg. Finally when they aquired enough mining power they could blacklist exchange hotwallets or all manner of nefariousness. Lets further assume that everyone will act purely in their own self interest. For simplicity lets call the attacker "Spectre Pool".

Accumulation Phase

Assuming Spectre Pool can hit something like 41% of the hashing power, the first goal is to accumulate more resources to hit 51%. Since pool mining is a commodity market, all Spectre has to do in this imaginary world is offer more than the market rate. Since they are already at 41% hashrate, they need to entice another 10% of the market to come to their pool. The obvious way to do this would be to offer a "new customer bonus" or something like that. Some promotion where they pay 1% above market price for the hashing power of pool members. So, given a network hashrate of 116.73 EH and a market rate of 0.101 USD/TH per day, the cost they would have to bear to offer a 1% promotion to entice 10% of the network would be:
116.73_EH / 0.101_USD/TH * 10% * 1% = 1,155,742 USD per day for each 1% "bonus"
So, assuming they were willing to spend that much on "marketing", and that all miners worked in their own self interest, eventually they could lure enough miners over to achive 51%. Once they hit this threshold they could scale back on the "marketing" and thus reduce their daily burn.

Acceleration phase

Once at 51%, the next attack of Spectre will be to put their smallest competitor out of buisness. Lets call that the "Bond Pool", and pretend that Bond has 1.5% of the network hashing power. To put Bond out of buisness, with 51%, Spectere will need to reorg whenever Bond wins a block. By reorging to a chain without Bond, this will put Spectre one block behind and they will need to catch up. Once the reorg begins, Spectre will need to produce the longest chain on its own while starting one block behind. So we need to determine how long (statisticly) it will take Specter to produce n+1 blocks and compare that to how long (statisticly) it will take Bond to win one block.
Although this can be hammered out in an iterive calculation, a better approach will be an algebraic solution. Lets walk through the equations:
You can put the following into a GeoGebra CAS calculator to substitute and simplify the equations
solve(n*m = s*(n+1), n) M = 1/2-d S = 1/2+d m = t/M s = t/S solve(n*m = s*(n+1), d) n = s/(m-s) b = m*M/p solve(b = s*(n+1),p)
This will produce the following equations for the values we are interested in.
m(t,d): t/(1/2-d) # from `m` define s(t,d): t/(1/2-d) # from `s` define n(s,m): s/(m-s) # from `n` solve d(n): 1/(4*n+2) # from `d` solve p(d): 2*d # from `p` solve b(t,p): t/p # from `b` define
Plugging the equations into excel produces the following (assuming t=10)
n d p m s b
25 0.98% 1.96% 20.40 19.62 510
20 1.22% 2.44% 20.50 19.52 410
15 1.61% 3.23% 20.67 19.38 310
10 2.38% 4.76% 21 19.09 210
5 4.55% 9.09% 22 18.33 110
4 5.56% 11.11% 22.50 18 90
3 7.14% 14.29% 23.33 17.50 70
2 10% 20% 25 16.67 50
1 16.67% 33.33% 30 15 30
So once d=0.98%, Specture will have 50.98% of the hashing power, allowing him to eject 1.96% of all blocks mined at will. Of course this is all statistical, so Spectre will want some margin for randomness. So it would make sense to attach 1.5% of the blocks when Spectre reaches 51%
So once Spectre reaches 51% he has enough hashing power to prevent any of Bonds blocks (1.5%) from being included. Spectre can win a reorg (statistically) every 8.5 hrs and Bond can only produce a block (statisticly) every 11.1 hours. So once this attack starts, Spectre simply flashes his promotion to lure the miners in the Bond pool (who are receiving no reward) over to the Spectre pool. If he only gets one third of them, then he can increase his influence to 52%
Doing the same math again, with 52% Spectre can ice out any pool who has up to 4% of the hashing. Then running the promotion, Spectre will try to get 40% of the "homeless miners". Now Spectre's power grows to 55% giving him the power to ice out 10% of his competitors. This can cascade on and on until Spectre is the only public pool left.
Now, at 51% the attack and reorgs take many hours, but as more and more pools get targeted, more and more miners will jump ship and end up at Spectre so long as they can hold the promotion. Bond's only choice would be to either close up, or leverage everything and mine at a loss for weeks hoping that Spectre eventually drops below the threshold for his attack.
Of course Spectre has even more tremendous expenses. To offer the 1% promo to 10% of the network would cost Spectre $1.16 million / day, or 3.52 million per month for each percent of miners it lures over. So going from 41% to 61% would cost Spectre $70.3 million / month, but at that point he can attack 20% of the network giving him a reach of about 80% which is pretty much the entire pooled mining capacity today. Seems like $70 million is a small price to pay to buy the entire bitcoin network.
Other expenses Spectre would accrue would be related to the attacks and reorgs. The early attacks will take hours and throughout Spectre needs to continue payouts to the pool even though he is generating no BTC durring the attack. So long as his chain is orphaned, his blocks have no value. Only after the attack and reorg when his chain becomes longest will he be able to claim the block reward for all the blocks he minded. This (in my opinion) will the the hardest challenge. The first attack and 25 block reorg will require Spectre to put his entire 51% hashing power on an orphaned chain for 8 hours requireing $208.6 million in payouts. Once he wins the attack and the chain reorgs he can cover his expeses with the block reward, but borrowing $208 million for 8 hours is still a very difficult thing to pull off. The interest alone on the attack is over $40,000 (20% interest compounded continually). Below is a table of the calculations
Specte Bond Promo Cost Hrs Blks Levrg / Block Reorg Leverage Rate Int Cost
51.00% 1.50% $1,155,743 8.497 25 $8,025,990 $208,675,743 20% $40,485
51.50% 2.50% $1,232,745 5.825 17 $8,025,990 $144,467,822 20% $19,215
52.50% 4.50% $1,336,143 3.492 10 $8,025,990 $88,285,891 20% $7,039
54.50% 7.50% $1,562,998 2.141 6 $8,025,990 $56,181,931 20% $2,746
58.50% 14.50% $2,023,385 1.140 3 $8,025,990 $32,103,960 20% $835
66.70% 33.30% $2,970,442 0.500 1 $8,025,990 $16,051,980 20% $183
Of course, once Spectre gets 2/3 of the hashing power he controls the entire chain since he can include or exclude any block he wants. So this "Total Self Interest" simulation of a 6 day attack puts Spectre's expenses at $10.3 million in promotions and $71,000 in interest, or about $10.4 million total.

This will produce the following equations for the values we are interested in.

solve(nm = s(n+1), d) n = s/(m-s) b = m*M/p
``` Tb = The avg time between blocks won by Bond durring the reorg Ts = The avg time for Spectre to produce a block durring the reorg Tm = The avg time for the main chain to produce a block durring the reorg n = The number of blocks Specter will need to reorg
Tb = 10_min / 49% / 3% = 10.89 Hrs Ts = 10_min / 51% = 19.61 Min Tm = 10_min / 49% = 20.41 Min
Solve for the amount of blocks Specter can reorg Tmn > Ts(n+1) Tnn > Tsn + Ts n > Ts/(Tn - Ts) n > 24.5
Therefore: Spectre can produce 26 blocks faster than the main chain can produce 25. Specter has to win the reorg before Bond produces another block
Assert: Ts * (n+1) < Tb 19.61_min * 26 < 10.89_hrs 8.50_hrs < 10.89_hrs ```
So once Spectre reaches 51% he has enough hashing power to prevent any of Bonds blocks from being included. Spectre can win a reorg (statistically) every 8.5 hrs and Bond can only produce a block (statisticly) every 10.89 hours. So once this attack starts, Spectre simply flashes his promotion to lure the miners in the Bond pool (who are receiving no reward) over to the Spectre pool. If he only gets one third of them, then he can increase his influence to 52%
Doing the same math again, with 52% Spectre can ice out any pool who has up to 7% of the hashing. Then running the promotion, Spectre will try to get 40% of the "homeless miners". Now Spectre's power grows to 55% giving him the power to ice out 16% of his competitors. This can cascade on and on until Spectre is the only public pool left.

I made an upgraded calculator for Hashflare, with reinvestments and difficulty increase!

Final EDIT: I have deactivated the links, too many people asking to edit. I recommend to everyone: buy Bitcoin, ETH or altcoins and hold them. As for me, I'm all in on RaiBlocks -> /RaiBlocks
EDIT 1: Changed to consider an optional BTC price increase
EDIT 2: Changed to consider mining fees, thanks for the suggestions
EDIT 3: Optimize number of days using Goal Seek
EDIT 4: Fixed bug in BTC price increase ( thanks madmax_br5 ) - you will now see bigger profits in the chart as it is using the projected increased value.
EDIT 5: Added comparison with buying BTC now and selling later. 3-4x more in my case.
EDIT 6: Overhaul after WandringAnteater 's suggestions. He also gave a more in depth explanation of the inputs and outputs here
EDIT 7: Changed to reinvest from the payout and not balance; fallback to balance if payout < 0.01 TH/s equivalent. Thanks to u/erikkubica for reporting the bug.
I saw many calculators around the sub (thanks for those by the way!), but they didn't consider the increases in difficulty, making for huge profits in the end. This one considers a constant increase in difficulty, compounded (specify the amount and period of increase).
Reinvestment is also considered, you can specify the percentage and how long you wish to reinvest.
There are still many things that are unpredictable, but this at least can give us a more conservative view on potential profits (no longer 10x, but about 3x in my case - at current BTC price).
Maybe someone smarter than me can take this calculator and create automatic optimization on the reinvestment percentage and time. As of now you have to insert your values and wait about 5 seconds to re-calc.
Any criticism is appreciated!

Asicpower AP9-SHA256 Review


Asicpower AP9-SHA256 Review

Bitmain is regarded as one of the most influential companies in the ASIC mining industry. It is estimated that they have manufactured approximately 53% of all mining equipment.Without including their mining profits, that’s around $140 million dollars in sales. These figures are staggering, but Bitmain’s monopoly of the Bitcoin ASIC market may come to an end, following the release of PowerAsic’s asicpower AP9-SHA256.

About the asicpower AP9-SHA256

Designed with brand new technology and boasting 94 TH/s per miner, the AP(-SHA256 is the most powerful and efficient Bitcoin miner to date.PowerAsic claims they spent $12 million dollars on research, development, and prototypes.PowerAsic also noted that their miners take advantage of ASICBOOST, an exploit of Bitcoin’s algorithm which improves mining efficiency by 20%.An unusual approach separate Powerasic’s miner to the other manufactures is the implementation of copper heat-sink claimed to have a superior thermal conductivity 69% better than aluminium. Don’t take their words for it but confirm the facts are correct on widely well known and published science documents as this one.The first batch of miners were announced and made available for order in August of 2019, with start scheduled for shipment in September, 2019.
Powerasic claims that the machines are around 40 percent more productive than the most proficient ASIC on the market, Bitmain’s Antminer S17.According to PowerAsic, they started a mining project with the aim to bring much needed competition to the market…We want to ‘make SHA256 great again.Sitting at the hefty price of $2,795.00, the powerasic AP9-SHA256 is far from affordable for the average person. Fortunately, due to the newly born rivalry between Bitmain and Powerasic, the price will probably lower with time and competition.The power supply for this unit is included and integrated in the top-box also including the controler card as a one unit. You will also get standard power cable, network cable, manual and software in the packet. In comparison to the price of the Antminer S17 , the Powerasic AP9-Sha256 is a better value.

Power Supply

The integrated PSU 3300W has a inputVoltage 220V 50Hz 30A. There are 2 fan 40mm., 1 fan 60mm to keep it cool and the power cable 3 legs following CEE 7 standard.Professional mining hardware runs optimally at 220-240V, hence why mining farms step down their own electricity supply to 220-240V. Note that 220V current is only found outside of the US – American outlets are 110V by default. Unless you want to hire an electrician, this could cause some people trouble adapt to the eficient and recomended 220V power needed, still 110V will get the job done, but they are not ideal for optimum mining performance.

Power Consumption

Thanks to the powerasic AP9-HA256’s new 7nm generation of ASIC chips, the AP9-SHA256 has become the most electrically-efficient miner on the market.Consuming merely 30.J/TB, or 2860W from the wall, the 16T is 30% more electrically-efficient than the Antminer S17.

Profitability

Powerasic ’s new ASIC technology is impressive. When compared to its closest competitor, the Antminer S17, the powerasic AP9-HA256 is the clear winner. It hashes at 94 TH/s, as opposed to the S17’s 56 TH/s. Moreover, the the AP9-HA256 consumes 30J/GH, whereas the S17 consumes 39-45J/TB.The difference in power consumption is miniscule, but when it comes to large-scale mining, the the AP9-HA256’s edge will drastically increase the profitability of a mining operation. This ASIC is profitable not only for mining on a large scale, but for the individual miner as well.Take a look at the projected mining profitability of a single miner:Note that is appears profitable even with high electricity costs ($0.1 per KW/h). With $0.05 / KW/h it’s even more profitable:📷Each powerasic AP9-HA256 will generate about $6,009 per year (calculated with 1 BTC=$10,141.5). Mining profitability may vary. You can usethis free profitability calculator to determine your projected earnings.

Is powerasic AP9-HA256 a Scam?

There is been a lot of talk on Twitter that powerasic AP9-HA256 is a scam. It appears it is not, as many users are already claiming to have received their miners.Slush, the creator ot Slush Mining Pool and the TREZOR hardware wallet, claims on Twitter that he has seen units and knows people who have had their miners delivered:

Verdict: Is The Antminer S17 Outdated?

When the first batch of Bitmain’s Antminer S17 ASICs reached the eager hands of miners, they were all the rage. The S17 was renowned as the most efficient ASIC miner on the market. Many used the S17 as the industry’s golden standard.Up until the launch of the powerasic AP9-HA256, it was the golden standard.But, now?Things have changed.Not only is the powerasic AP9-HA256 more powerful than its predecessor from Bitmain, but also more efficient, and therefore, more profitable.Ever since the announcement of the new ASIC, there was widespread speculation of its legitimacy – and rightly so.The Bitcoin community has been plagued with small, phony companies manipulating images of preexisting antminers as a ploy to hype up their fake products. Nevertheless, powerasic AP9-HA256 is taking things seriously, and their first batch of miners have lived up to expectations.The fact of the matter is, Bitmain’s most powerful and efficient antminer has been dethroned by the new reigning king of ASICs: The powerasic AP9-HA256.

Conclusion

Bitmain has dominated the ASIC market since its inception in 2013.There are a few other companies producing ASICs. However, before the creation of PowerAsics AP9-SHA256., Bitmain was the only company with a proven track record that sold efficient miners directly to the public.Powerasic AP9-HA256 has the potential to bring Bitmain’s monopoly to an end. Powerasic AP9-HA256 has a bright future ahead of them. Now that Bitmain has noteworthy competition, it will be interesting to see how it affects the market. The powerasic AP9-HA256 is the best option (for now) for anyone getting started with mining. Powerasic’s innovation should force other ASIC producers to innovate and force other companies to release new miners with better efficiency. So whether you’re buying a miner now or soon, you’re likely to benefit from the development of this new miner. For more, Visit Us: https://asicpower.net/product.php
