How to import private keys - Bitcoin Wiki

I tried to create a new Electrum on my Windows 7 using an old address from my old Electrum. I went to create default wallet > Import Bitcoin addresses or private keys Then i typed an address. But i could type the Next button. How do i proceed?

Windows / Linux Guide to using Trezor with Bitcoin Core (HWI)

This is a guide to using your Trezor with Bitcoin Core. It may seem like more trouble than it's worth but many applications use Bitcoin Core as a wallet such as LND, EPS, and JoinMarket. Learning how to integrate your Trezor into a Bitcoin Core install is rather useful in many unexpected ways. I did this all through the QT interfaces, but it's simple to script. There is a much simpler guide available from the HWI github, and the smallest Linux TLDR is here
Unfortunately, I don't have access to a Coldcard or Ledger. I'm not sure how the setpin or -stdinpass parameters are handled on that HW.

( A ) Install TrezorCTL, HWI, and build GUI

You only need to set the wallet up once, but may repeat to upgrade

( A.I ) Download extract and install HWI

  1. Download and isntall Python
  2. Download https://github.com/bitcoin-core/HWI/archive/1.1.2.zip
  3. Extract it to a working folder (assumes C:\User\Reddit\src\HWI)
  4. Change Directory (cd) to working folder cd "C:\User\Reddit\src\HWI"

  2. Launch a mingw64.exe shell
  3. CD to working folder cd "C:\User\Reddit\src\HWI"
  4. Enter venv source .venv/Scripts/activate 1
  5. Run UI build bash contrib/generate-ui.sh

( B ) Create a Trezor wallet in Bitcoin Core (testnet)

You only need to set the wallet up once, no private key data is stored, only xpub data

( B.I ) Retrieve keypool from HWI-QT

  1. Launch hwi-qt.exe --testnet (assuming testnet)
  2. Click Set passphrase (if needed) to cache your passphrase then click Refresh
  3. Select you trezor from the list then click Set Pin (if needed)
  4. Ensure your Trezor in the dropdown has a fingerprint
  5. Select Change keypool options and choose P2WPKH
  6. Copy all the text from the Keypool textbox

( B.II ) Create the wallet in Bitcoin QT

  1. Launch Bitcoin Core (testnet) (non-pruned) 2
  2. Select Console from the Window menu
  3. Create a wallet createwallet "hwi" true
  4. Ensure that hwi is selected in the console wallet dropdown
  5. Verify walletname using the getwalletinfo command
  6. Import keypool importmulti '' (note ' caging)
  7. Rescan if TXNs are missing rescanblockchain 3

( C.I ) Grab Tesnet coins

  2. Ensure that the Wallet dropdown has hwi selected
  3. Select Create new receiving address and copy address
  4. Google "bitcoin testnet faucet" and visit a few sites
  5. Answer captcha and input your addressed copied from C.I.3

( D ) Spending funds with HWI

This is how you can spend funds in your Trezor using Bitcoin Core (testnet)

( D.I ) Create an unsigned PSBT

  1. Select the Send tab in Bitcoin Core (testnet)
  2. Ensure that the Wallet dropdown has hwi selected
  3. Verify your balance in Watch-only balance
  4. Rescan if balance is wrong (see B.II.7) 3
  5. Craft your TXN as usual, then click Create Unsigned
  6. Copy the PSBT to your clipboard when prompted

( D.II ) Sign your PSBT

  1. In HWI-QT click Sign PSBT
  2. Paste what you copied in D.I.6 in PSBT to Sign field
  3. Click Sign PSBT
  4. Copy the text for PSBT Result

( D.III ) Broadcast your TXN

  1. Select the Console window in Bitcoin Core (testnet)
  2. Ensure that the Wallet dropdown has hwi selected
  3. Finalize PSBT: finalizepsbt
  4. Copy the signed TXN hex from the hex field returned
  5. Broadcast TXN: sendrawtransaction

Final Thoughts

I did this all through the GUI interfaces for the benefit of the Windows users. Windows console is fine, but the quote escaping in windows console is nightmarish. Powershell would be good, but that throws this on a whole another level for most Windows folks.
There is also the need to use HWI-QT due to a bug in blank passphrases on the commandline. You can work around it by toggling passphrase off or on, but again, it's more than I wanted to spell out.
Footnotes:
  • 1. - Later version of python put the activate script under 'bin' instead of 'Script'
  • 2. - You can run pruned, but you need to have a fresh wallet
  • 3. - Rescan is automatic on 'importmulti' but I was pruned so it was wierd

Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

Bob The Magic Custodian



Summary: Everyone knows that when you give your assets to someone else, they always keep them safe. If this is true for individuals, it is certainly true for businesses.
Custodians always tell the truth and manage funds properly. They won't have any interest in taking the assets as an exchange operator would. Auditors tell the truth and can't be misled. That's because organizations that are regulated are incapable of lying and don't make mistakes.

First, some background. Here is a summary of how custodians make us more secure:

Previously, we might give Alice our crypto assets to hold. There were risks:

But "no worries", Alice has a custodian named Bob. Bob is dressed in a nice suit. He knows some politicians. And he drives a Porsche. "So you have nothing to worry about!". And look at all the benefits we get:
See - all problems are solved! All we have to worry about now is:
It's pretty simple. Before we had to trust Alice. Now we only have to trust Alice, Bob, and all the ways in which they communicate. Just think of how much more secure we are!

"On top of that", Bob assures us, "we're using a special wallet structure". Bob shows Alice a diagram. "We've broken the balance up and store it in lots of smaller wallets. That way", he assures her, "a thief can't take it all at once". And he points to a historic case where a large sum was taken "because it was stored in a single wallet... how stupid".
"Very early on, we used to have all the crypto in one wallet", he said, "and then one Christmas a hacker came and took it all. We call him the Grinch. Now we individually wrap each crypto and stick it under a binary search tree. The Grinch has never been back since."

"As well", Bob continues, "even if someone were to get in, we've got insurance. It covers all thefts and even coercion, collusion, and misplaced keys - only subject to the policy terms and conditions." And with that, he pulls out a phone-book sized contract and slams it on the desk with a thud. "Yep", he continues, "we're paying top dollar for one of the best policies in the country!"
"Can I read it?' Alice asks. "Sure," Bob says, "just as soon as our legal team is done with it. They're almost through the first chapter." He pauses, then continues. "And can you believe that sales guy Mike? He has the same year Porsche as me. I mean, what are the odds?"

"Do you use multi-sig?", Alice asks. "Absolutely!" Bob replies. "All our engineers are fully trained in multi-sig. Whenever we want to set up a new wallet, we generate 2 separate keys in an air-gapped process and store them in this proprietary system here. Look, it even requires the biometric signature from one of our team members to initiate any withdrawal." He demonstrates by pressing his thumb into the display. "We use a third-party cloud validation API to match the thumbprint and authorize each withdrawal. The keys are also backed up daily to an off-site third-party."
"Wow that's really impressive," Alice says, "but what if we need access for a withdrawal outside of office hours?" "Well that's no issue", Bob says, "just send us an email, call, or text message and we always have someone on staff to help out. Just another part of our strong commitment to all our customers!"

"What about Proof of Reserve?", Alice asks. "Of course", Bob replies, "though rather than publish any blockchain addresses or signed transaction, for privacy we just do a SHA256 refactoring of the inverse hash modulus for each UTXO nonce and combine the smart contract coefficient consensus in our hyperledger lightning node. But it's really simple to use." He pushes a button and a large green checkmark appears on a screen. "See - the algorithm ran through and reserves are proven."
"Wow", Alice says, "you really know your stuff! And that is easy to use! What about fiat balances?" "Yeah, we have an auditor too", Bob replies, "Been using him for a long time so we have quite a strong relationship going! We have special books we give him every year and he's very efficient! Checks the fiat, crypto, and everything all at once!"

"We used to have a nice offline multi-sig setup we've been using without issue for the past 5 years, but I think we'll move all our funds over to your facility," Alice says. "Awesome", Bob replies, "Thanks so much! This is perfect timing too - my Porsche got a dent on it this morning. We have the paperwork right over here." "Great!", Alice replies.
And with that, Alice gets out her pen and Bob gets the contract. "Don't worry", he says, "you can take your crypto-assets back anytime you like - just subject to our cancellation policy. Our annual management fees are also super low and we don't adjust them often".

How many holes have to exist for your funds to get stolen?
Just one.

Why are we taking a powerful offline multi-sig setup, widely used globally in hundreds of different/lacking regulatory environments with 0 breaches to date, and circumventing it by a demonstrably weak third party layer? And paying a great expense to do so?
If you go through the list of breaches in the past 2 years to highly credible organizations, you go through the list of major corporate frauds (only the ones we know about), you go through the list of all the times platforms have lost funds, you go through the list of times and ways that people have lost their crypto from identity theft, hot wallet exploits, extortion, etc... and then you go through this custodian with a fine-tooth comb and truly believe they have value to add far beyond what you could, sticking your funds in a wallet (or set of wallets) they control exclusively is the absolute worst possible way to take advantage of that security.

The best way to add security for crypto-assets is to make a stronger multi-sig. With one custodian, what you are doing is giving them your cryptocurrency and hoping they're honest, competent, and flawlessly secure. It's no different than storing it on a really secure exchange. Maybe the insurance will cover you. Didn't work for Bitpay in 2015. Didn't work for Yapizon in 2017. Insurance has never paid a claim in the entire history of cryptocurrency. But maybe you'll get lucky. Maybe your exact scenario will buck the trend and be what they're willing to cover. After the large deductible and hopefully without a long and expensive court battle.

And you want to advertise this increase in risk, the lapse of judgement, an accident waiting to happen, as though it's some kind of benefit to customers ("Free institutional-grade storage for your digital assets.")? And then some people are writing to the OSC that custodians should be mandatory for all funds on every exchange platform? That this somehow will make Canadians as a whole more secure or better protected compared with standard air-gapped multi-sig? On what planet?

Most of the problems in Canada stemmed from one thing - a lack of transparency. If Canadians had known what a joke Quadriga was - it wouldn't have grown to lose $400m from hard-working Canadians from coast to coast to coast. And Gerald Cotten would be in jail, not wherever he is now (at best, rotting peacefully). EZ-BTC and mister Dave Smilie would have been a tiny little scam to his friends, not a multi-million dollar fraud. Einstein would have got their act together or been shut down BEFORE losing millions and millions more in people's funds generously donated to criminals. MapleChange wouldn't have even been a thing. And maybe we'd know a little more about CoinTradeNewNote - like how much was lost in there. Almost all of the major losses with cryptocurrency exchanges involve deception with unbacked funds.
So it's great to see transparency reports from BitBuy and ShakePay where someone independently verified the backing. The only thing we don't have is:
It's not complicated to validate cryptocurrency assets. They need to exist, they need to be spendable, and they need to cover the total balances. There are plenty of credible people and firms across the country that have the capacity to reasonably perform this validation. Having more frequent checks by different, independent, parties who publish transparent reports is far more valuable than an annual check by a single "more credible/official" party who does the exact same basic checks and may or may not publish anything. Here's an example set of requirements that could be mandated:
There are ways to structure audits such that neither crypto assets nor customer information are ever put at risk, and both can still be properly validated and publicly verifiable. There are also ways to structure audits such that they are completely reasonable for small platforms and don't inhibit innovation in any way. By making the process as reasonable as possible, we can completely eliminate any reason/excuse that an honest platform would have for not being audited. That is arguable far more important than any incremental improvement we might get from mandating "the best of the best" accountants. Right now we have nothing mandated and tons of Canadians using offshore exchanges with no oversight whatsoever.

Transparency does not prove crypto assets are safe. CoinTradeNewNote, Flexcoin ($600k), and Canadian Bitcoins ($100k) are examples where crypto-assets were breached from platforms in Canada. All of them were online wallets and used no multi-sig as far as any records show. This is consistent with what we see globally - air-gapped multi-sig wallets have an impeccable record, while other schemes tend to suffer breach after breach. We don't actually know how much CoinTrader lost because there was no visibility. Rather than publishing details of what happened, the co-founder of CoinTrader silently moved on to found another platform - the "most trusted way to buy and sell crypto" - a site that has no information whatsoever (that I could find) on the storage practices and a FAQ advising that “[t]rading cryptocurrency is completely safe” and that having your own wallet is “entirely up to you! You can certainly keep cryptocurrency, or fiat, or both, on the app.” Doesn't sound like much was learned here, which is really sad to see.
It's not that complicated or unreasonable to set up a proper hardware wallet. Multi-sig can be learned in a single course. Something the equivalent complexity of a driver's license test could prevent all the cold storage exploits we've seen to date - even globally. Platform operators have a key advantage in detecting and preventing fraud - they know their customers far better than any custodian ever would. The best job that custodians can do is to find high integrity individuals and train them to form even better wallet signatories. Rather than mandating that all platforms expose themselves to arbitrary third party risks, regulations should center around ensuring that all signatories are background-checked, properly trained, and using proper procedures. We also need to make sure that signatories are empowered with rights and responsibilities to reject and report fraud. They need to know that they can safely challenge and delay a transaction - even if it turns out they made a mistake. We need to have an environment where mistakes are brought to the surface and dealt with. Not one where firms and people feel the need to hide what happened. In addition to a knowledge-based test, an auditor can privately interview each signatory to make sure they're not in coercive situations, and we should make sure they can freely and anonymously report any issues without threat of retaliation.
A proper multi-sig has each signature held by a separate person and is governed by policies and mutual decisions instead of a hierarchy. It includes at least one redundant signature. For best results, 3of4, 3of5, 3of6, 4of5, 4of6, 4of7, 5of6, or 5of7.

History has demonstrated over and over again the risk of hot wallets even to highly credible organizations. Nonetheless, many platforms have hot wallets for convenience. While such losses are generally compensated by platforms without issue (for example Poloniex, Bitstamp, Bitfinex, Gatecoin, Coincheck, Bithumb, Zaif, CoinBene, Binance, Bitrue, Bitpoint, Upbit, VinDAX, and now KuCoin), the public tends to focus more on cases that didn't end well. Regardless of what systems are employed, there is always some level of risk. For that reason, most members of the public would prefer to see third party insurance.
Rather than trying to convince third party profit-seekers to provide comprehensive insurance and then relying on an expensive and slow legal system to enforce against whatever legal loopholes they manage to find each and every time something goes wrong, insurance could be run through multiple exchange operators and regulators, with the shared interest of having a reputable industry, keeping costs down, and taking care of Canadians. For example, a 4 of 7 multi-sig insurance fund held between 5 independent exchange operators and 2 regulatory bodies. All Canadian exchanges could pay premiums at a set rate based on their needed coverage, with a higher price paid for hot wallet coverage (anything not an air-gapped multi-sig cold wallet). Such a model would be much cheaper to manage, offer better coverage, and be much more reliable to payout when needed. The kind of coverage you could have under this model is unheard of. You could even create something like the CDIC to protect Canadians who get their trading accounts hacked if they can sufficiently prove the loss is legitimate. In cases of fraud, gross negligence, or insolvency, the fund can be used to pay affected users directly (utilizing the last transparent balance report in the worst case), something which private insurance would never touch. While it's recommended to have official policies for coverage, a model where members vote would fully cover edge cases. (Could be similar to the Supreme Court where justices vote based on case law.)
Such a model could fully protect all Canadians across all platforms. You can have a fiat coverage governed by legal agreements, and crypto-asset coverage governed by both multi-sig and legal agreements. It could be practical, affordable, and inclusive.

Now, we are at a crossroads. We can happily give up our freedom, our innovation, and our money. We can pay hefty expenses to auditors, lawyers, and regulators year after year (and make no mistake - this cost will grow to many millions or even billions as the industry grows - and it will be borne by all Canadians on every platform because platforms are not going to eat up these costs at a loss). We can make it nearly impossible for any new platform to enter the marketplace, forcing Canadians to use the same stagnant platforms year after year. We can centralize and consolidate the entire industry into 2 or 3 big players and have everyone else fail (possibly to heavy losses of users of those platforms). And when a flawed security model doesn't work and gets breached, we can make it even more complicated with even more people in suits making big money doing the job that blockchain was supposed to do in the first place. We can build a system which is so intertwined and dependent on big government, traditional finance, and central bankers that it's future depends entirely on that of the fiat system, of fractional banking, and of government bail-outs. If we choose this path, as history has shown us over and over again, we can not go back, save for revolution. Our children and grandchildren will still be paying the consequences of what we decided today.
Or, we can find solutions that work. We can maintain an open and innovative environment while making the adjustments we need to make to fully protect Canadian investors and cryptocurrency users, giving easy and affordable access to cryptocurrency for all Canadians on the platform of their choice, and creating an environment in which entrepreneurs and problem solvers can bring those solutions forward easily. None of the above precludes innovation in any way, or adds any unreasonable cost - and these three policies would demonstrably eliminate or resolve all 109 historic cases as studied here - that's every single case researched so far going back to 2011. It includes every loss that was studied so far not just in Canada but globally as well.
Unfortunately, finding answers is the least challenging part. Far more challenging is to get platform operators and regulators to agree on anything. My last post got no response whatsoever, and while the OSC has told me they're happy for industry feedback, I believe my opinion alone is fairly meaningless. This takes the whole community working together to solve. So please let me know your thoughts. Please take the time to upvote and share this with people. Please - let's get this solved and not leave it up to other people to do.

How to Recover Lost Bitcoin

It is quite easy and possible for us to misplace money or even other things from time to time. You can lose your car keys, forget your parking spot at the mall, and so on. But what about losing something digital, like cryptocurrency? And since bitcoin doesn’t exist in a physical form, it can’t be dropped on the street or left behind somewhere. But it is still possible for us to lose our bitcoin, as many people have discovered.We are going to look at how cryptocurrency gets lost, where it goes, and how you can avoid it happening to you. And most importantly, how to recover lost bitcoin.
How does Bitcoin Get Lost?
The total available supply of Bitcoin is capped at 21 million, with new ones released every day. It’s expected that we’ll reach that cap sometime around the year 2140, although it could be sooner.If you lose a coin or note of your local currency, it doesn’t matter much to the economy as a whole because your government simply mints new money on a regular basis.It’s not known exactly how many Bitcoin are currently lost, in part because the definition of ‘lost’ varies depending on who you ask, and some may be reclaimed in the future. Though going beyond the void retrieve it isn’t easy.
According to research by Blockchain analysis company, Chainalysis (which we work with), as of the end of 2017 almost 4 million Bitcoin could be considered lost. It’s unlikely the number hasn’t increased much since then, as the higher price encourages people to be more careful. So, as it stands, the total circulating supply is set to be around 17 million Bitcoin. Stolen or lost Bitcoin can be recovered by hiring a Funds Recovery Expert to help you get back your lost bitcoin.
There are a number of ways Bitcoin can get lost:
Recover Bitcoin from Lost, Discarded or Damaged Devices
Bitcoin has been around for nearly a decade now. During that time, technology has changed a lot and the average person probably isn’t still cranking up Windows Vista to trade crypto. In some cases, people will lose their laptop or throw it away, forgetting that they have Bitcoin stored on it. Broken devices and fried motherboards also lead to losses. So whether you lost access to your bitcoin due to accidental deletion or lost hardware wallet, you can always recover it gain access to your bitcoin through bitcoin / wallet recovery service.
Recover Forgotten Bitcoin
Yep, it is possible to buy or mine Bitcoin then forget you own it. This sounds like a caviar-and-champagne problem, but in the early days you could easily mine thousands of Bitcoin on a normal laptop and it cost almost nothing. That non-existent cost meant most people didn’t really see it as something that might ever have value, so many just forgot about it.Recover Bitcoin Sent to a Wrong AddressSending Bitcoin to an incorrect address is like mailing a letter to a sealed empty house where no one lives or ever will live. It may sound like Mary Shelley’s version of losing Bitcoin, and it’s just as bleak. It’s impossible for anyone to open the door and retrieve it. This can happen if you mistype an address and transactions cannot be reversed.
Recover Forgotten Bitcoin Private Keys and Passwords
Your private key gives access to your Bitcoin. If you lose this, it’s like forgetting the code for an unbreakable safe. Some people have written down their credentials, only to lose or accidentally throw away the piece of paper. Others committed them to memory, then later forgot it. It is important never to lose your bitcoin recovery phrase, but don't worry if you do. You can always recover your lost bitcoin with or without the seed phrase. Have you lost your wallet password? Don't be worried, you can easily get it back with the help of [email protected]
Can lost Bitcoin be Found or Retrieved?
Generally speaking, whether lost bitcoin can be found or not depends on how it was lost. Considering the quantity of missing cryptocurrency out there, people have begun offering services to help recover lost bitcoin. These include data recovery specialists, but you need a professional recovery expert like [email protected] to help you get back your lost bitcoin.
Contact [email protected] to recover lost bitcoin, bitcoin cash, as well as all other forms of cryptocurrency. And you can be sure that no matter how long it has been lost, you will still get your bitcoin worth.

Claiming BCH from my bitcoin core wallet

Hi Guys,

I have a wallet which I've been using from around 2015 with bitcoin core (so its a wallet.dat).

I have spent coins since the split but I had coins at the split time.

Now of course I wish to claim these coins, but I wish to carry on using bitcoin core for btc.

I have installed Electron Cash, created a wallet.

Is it correct that

if I were to get the private keys from bitcoin core with dumpprivkey then enter the output from that command into the sweep window, is this correct?

This will not affect my correct btc held in Bitcoin Core?

This will show the balance I had as of block 478558 in Electron Cash?

Or should I download Bitcoin ABC, and import my Bitcoin Core wallet.dat/copy it over to Bitcoin ABC?(the problem with this is I do not have the resources for all the blocks needed to run a full node for BCH)

Thanks guys.

Top 10 Tricks to keep your wallet secure with Bitcoin

If you are keen on building a Bitcoin portfolio, then getting a Bitcoin wallet is one of the main things you need to remember. You can have several choices, but when it comes to using a Bitcoin wallet, you also need to know how to keep a secure Bitcoin wallet.
To keep your Bitcoin wallet safe, 10 tips and tricks:
  1. There are various types of wallets available, but when it comes to selecting the safest one, you must consider the hardware wallet. For those who have questions about cyber threats, it is fine. Companies such as Trezor and ledger have USB-like decisions that come with security features that can be accessed only with the private key.
2.Keep the private key offline- Holding the private key offline is another way to protect your Bitcoin wallet, i.e. you can pen down the key on the paper and keep it in a secure location.
  1. Keep an online check-Another part of the effect you can not ignore is that you must have a stable internet connexion. If you have a Bitcoin wallet on your laptop, then the public network must be linked to your laptop.
  2. Move to advanced antivirus software- The system's antivirus software is one of the main things that you do not undermine. Windows is vulnerable to more general malware and other malicious programmes. So, you have to consider downloading an advanced antivirus system if you are using a Windows operating system.
  3. Neve click on a suspicious link-Take care of your internet malicious behaviour. Often you can experience fishy links; these are malware that can hack into your device and corrupt all the data. Make sure you sue the same URL address and make sure that you check the URL and verify that it is secure if you are using the online wallet where you are expected to enter the private key.
  4. Never share a private key- You must never share a private key with third parties, regardless of the degree of confidence. Ignoring private key exchange is a stern no.
  5. Use strong passwords-Another key factor that you need to take into consideration is the strong passwords that you use for the private key. To keep it powerful and original, it must be a combination of numbers and alphabets, make use of case-sensitive letters along with special characters.
  6. Never share a private key- You must never share a private key with others, regardless of the degree of trust.
  7. Use two-factor authentication-Using two-factor authentication is one of the simplest ways to keep your wallet secure. This nullifies any form of hazard.
  8. Digital wallet backup- Getting a digital wallet backup will keep your asset secure. You can use this digital wallet backup if you lose the wallet or your computer fails to work. Make sure you keep the backup in a secure place, and you can recover it quickly.
Conclusion- You can ensure the protection of your crypto-currency wallet with these simple tips. For more important news of this nature, contact theBlockchain Council today.

How much does it cost to develop a cryptowallet for business?

How much does it cost to develop a cryptowallet for business?
A cryptocurrency wallet is specific software that allows you to make global non-cash payments and keep your profit securely stored. There are multiple reasons why business owners switch to cryptocurrency wallets such as no government invasion, multi-currency operations, quickness, no physical currency involved. However, it is necessary to develop your personalized wallet if you want to scale your business and simplify financial transactions. In this article, we will discuss what is the average price of cryptowallet development and how it will benefit your business.
https://preview.redd.it/wxe1e9l5n5r51.jpg?width=2508&format=pjpg&auto=webp&s=5c0b9b94aba2bfe8f877b7aa3f27a0f0592ab5ce
Firstly, it is important to understand the necessity of cryptowallet for entrepreneurs:
  • some transactions require a long waiting period and verification in the bank:
  • high fees on international transactions and unprofitable currency exchange rate;
  • lack of privacy, since online money transfer through a bank is impossible without the provision of personal information;
How does cryptowallet work?
  • fast and secure transactions carried within a few minutes;
  • private keys are safely stored and the transaction is processed between blockchain network members:
  • transaction fees are relatively low in comparison with a bank;
  • a completely anonymous environment;
You should keep in mind a few things that will influence the cost before the development process
Wallet type
There are two main wallet types: the desktop (installed on the PC) and the mobile app that can provide users with constant access to their funds.
Bitcoin libraries
You can either create a cryptocurrency wallet using one of the libraries (e.g. Coinbase, BitcoinJ) for Android and iOS and synchronize it with various API’s or create an application from the scratch.
Size of the development company
If you decide to get a highly customized wallet app, the estimated price will largely depend on the size of the company you are choosing. Anyway, cryptowallet development requires large investments and even hiring a small-sized company will cost you from $15,000-$20,000. The pricing depends on the features included. Also, the type of coins you want to use in your wallet app is a factor that influences the cost. Since it is not possible to calculate the exact cost of development, we will present the average prices of the basic features that are compulsory in your app:
Backend development from $10,000
Design from $7,000
Web/Desktop $7,000
Also, you can add numerous features to secure and vary your transactions:
Secured authentication & authorization, Windows/Linux/Mac wallet, iOS app, Android app, push notifications, QR code scanner, customer support, multiple cryptocurrency, optional password protection etc.
The development of a cryptocurrency wallet is an innovative tool that can bring your business to the next level. Evercode Lab developed a unique multi-currency crypto wallets (Atomic Wallet and Guarda), guaranteeing the fastest transactions, maximum security, and anonymity. Our company provides a wide range of services from consulting to a full-time development team as well as crypto asset security.

I found a tape I wasn’t supposed to listen to.

I plan on destroying this laptop after posting this and will soon be untraceable. I am reaching out because something is not right. I feel as if something just is not lining up right in the universe. I feel like I am out of place. I come to post because I am not sure how much longer I have. I was taking the trash out last week and I think I saw something I should not have. It was a full moon that night and I was doing my regular chores. Feed the dogs, clean the dishes, take the trash out. Easy stuff like any other night. When I got to the dumpster I saw a cassette player on the ground looking like it was to be thrown out. I thought to myself it was just trash but something caught my eye. There was a piece of tape on it with a sharpie written across it. It stated "LISTEN URGENT" so I put it in my pocket and took it home.
If I knew what was on that tape I would have not brought it home that night. I didn't have a pair of headphones to listen to it with or at least didn't care to look for one at the time. I had put the tape down on my desk and went to play some video games without thinking much of it at the time. You see I didn't have much going for me. My mother was a single mom and I was the man of the house. I liked to play video games because that is what made me happy. It was getting late so I turned off my monitor and went to bed.
I woke up the next morning thinking about the tape because I had a dream about it the night before. The dream consists of me going to the trash and finding the cassette tape then someone getting out of their car when I was walking home pushing me down and taking the tape from me. It was a man with a black overcoat but couldn't see much of his face since it was dark out. And as soon as he took it I woke up. I thought to myself that having a dream of it already had to mean something so I found some headphones and plugged them into the aux input and pressed play.
"What did you see that night" A man asked
"I was super drunk and all I remember was seeing some guy beat the shit out of some other guy outside the bar." A women said
"Where did this take place? The man asked
"In the alley besides the bar.... Can I please go now?" The women proclaimed.
"No, not yet we have some more questions for you..." The man said
"What was that?" The man asked
You could hear a crash or something and the tape cut out. What the fuck was I listening to? An interrogation with the police? All I know is there is more on the tape and I definitely shouldn't be listening to this. I clicked skip and play again and it started back up.
"Where were we... Sorry about the inconvenience miss." The man smirked
"Who are you guys anyways? The cops?" The women asked.
"Ahaha very funny... she thinks were the feds..." The man talking to his partner.
"You guys aren't the police???" "Then who are you guys?" The women starting to panic
"We are the guys they call when shit gets bad." The man said
"I think we are finished here... just state your name and age and your good to go."
"OK... Carly Johnson, 23"
Tape Ends
Who the fuck were they? Who is this girl Carly... I thought to myself what this tape was doing with me. I looked up this girl's name and I didn't believe my eyes. Here I am looking at her obituary. She died weeks ago. Cause of death: Suicide.
Where do I begin. I just heard a tape of seems to be the police interrogating Carly and she all of sudden kills herself what the actual fuck. I guess these are the guys they call when shit gets bad. It says she jumped over a bridge in the town over from me at midnight. Why would a girl just do this out of nowhere and sounded decently happy on the tape. But then I saw one last thing on her obituary... it said "There was no body found. She had left a note." So she went missing huh and they ruled it off as a suicide. I went back to the tape and to my surprise it had corrupted and I couldn't play anything back. Just great. I wanted to know who these guys were? Why did they want to talk to Carly? Why did Carly all of sudden disappear?
This was all so hard to wrap my head around. None of this should be my business but somehow I feel like it is. I never even knew Carly but some way I feel like I did. Weird right. Maybe you can tell me if I'm nuts or if it's humane to feel this way. I had another dream last night and to my surprise it had to do with the tape again. But this time it was very strange. I was on the bridge where Carly apparently did what she did and there was something on the ground in the middle of the bridge and I couldn't really make out what it was so I walked over and it was the same tape except the writing on it this time was "They did this." I then rubbed my eyes and woke up in a ton of sweat. So is this supposed to be a sign or something? Like what are these nightmares supposed to mean? I still am wondering who the men were that were talking with Carly. I started looking up cases of bar fights or anything to do with fights relevant to a bar. To my surprise I found the case. Case # 06-123 Bar stabbing leaving man dead. Looks like it was big in the local news. I do not watch the news much but now I know what they were talking to Carly about. This was much bigger than I thought. This is still an open investigation. I was skimming over the reports and one of the officers said that a private sector of the FBI would be taking over the case and no more was to be discussed publicly until the case is closed.
A private sector of the FBI is now involved what the fuck. In this tiny ass town the FBI is getting involved. This is all so much to take in. Seems like there is more to it though. The FBI got involved with some little stabbing at a bar. The news article said if there is any information to help the case to contact the link that was shared underneath the article. I clicked the link and it brought me to some government website to report tips or some bullshit. I started to read and it said "If there is any information on this case please contact this phone number [DISCLOSED INFORMATION]. I then read it said if anyone knew of a missing cassette tape that it is crucial to the investigation and no more information was shared after that. So wonderful, I now know that I am holding a crucial part of evidence of a case for the FBI and the contents were corrupted. I don't know what to do at this point... I still am going to be doing my research and I plan on getting rid of this cassette tape. I will be updating this post as soon as more information is shared or I find something. In the meanwhile I need to stay on the low because there could be and will be people looking for me and what I have acquired.
Ill post an update in 24 hours. Until then, Goodbye.
Update 2
I only got a few hours of sleep last night... thoughts running through my head constantly. I promised an update and here it is. I have been thinking of what to do with this tape. I think the best option would be to get rid of it but I think that would be a felony or something so that options off the list. The second option I have is to give it to them. Yes, I know it sounds crazy absolute delusional you might say. OK let me stop you right there. The plan is to drop it off at a discrete location and call in an anonymous tip. Seems easy right. I hope. I have wiped off all my prints on it and ripped off the tape on the front of it. I am going to go to a gas station about 45 minutes away from here. There should be a payphone and the angle the cameras are at should not see me if I pull my car up to the left of the building. I will wear gloves for prints and wear a hoodie. I should be fine, no evidence that I was there with the tape. I will get back to you after the job is done. Wish me luck.
Update 3
So it went exactly like planned. I parked my car where there was no surveillance and got out with my black hoodie and called the number that I saw online. I said "The cassette tape is in the bathroom of the gas station for case # 06-123 and hung up. I got out of there as fast as possible. I am now home and well. I am still curious and looking into Carly. I think I came upon something. It is very unusual. Her mother wrote a Facebook post saying "I know those cops are fucking corrupt... they never even looked into her case!" I thought to myself how weird this is. Her own mother must have known something was up too. No body found, A bridge that no one was on that night. I know no one was on it because there was a detour for maintenance on the bridge that afternoon. The last thing that doesn't add up is someone had to write on that tape stating LISTEN URGENT. If they were police wouldn't that tape be in evidence or something. Correct me if I'm wrong but this shit doesn't just go missing and wind up at my dumpster. I have a feeling that the bridge is one of the places that I will find something leading me to what happened to Carly and why the FBI are involved. I am going to take a drive to that bridge and see if I can find anything. I'll update you when I get back.
Update 4
I think I came upon something I wasn't supposed to once again... I found a necklace underneath the bridge. Here is a picture of what I found. necklace You see I don't think the police actually investigated or they would have already found this. Still we aren't even dealing with the local police anymore we are dealing with some special sector of the FBI. I also found one other thing and I feel as if posting a picture would compromise this second tape I found. I have not brought my headphones with me but have a feeling whatever is on this second tape that it will be great. I am very concerned about Carly and what happened to her. Maybe she is on this tape again, maybe it will lead me somewhere. If I post this on reddit I have a feeling the FBI will be notified or something like that. So for precautionary reasons I will not give the name of the bridge or any locations further that could potentially fuck this up. I plan on digging deep and will share it all with you. Why does the FBI want something to do with some girls suicide?? Who were those men on the tape???? Moments ago I just got a call from a blocked caller... I declined the call because I never normally accept blocked caller ids. They left a message. He said
"Turn your eyes away from this or else... You have been warned." ENDS CALL
I am very frustrated right now because they somehow found my phone number. I thought I took all the precautionary measures. I guess the government is always watching though. My feeling is that I will have to get rid of everything that ties me to this case. I have looked up how to destroy a hard drive and it is as easy as swiping a strong magnet over it.
I want to mention to whoever is reading this that if you know who Carly Johnson is and or have any clues on what happened to her please indulge me. Do not share anything with anyone else except my account. You see you may not realize the full extent of this situation but, no need to worry. I will encrypt everything that is sent and no information will get out to the Federal Bureau of Investigation.
Should I be scared? Because I am terrified. I need to know these answers because I am so devoted already. I was just warned to stop looking into this. I have no idea how they got my phone number. I believe we are dealing with not just a suicide but, possibly a government cover up or something worse. If anyone has any tips on what I could possibly do that would help please comment, I can take all the help I can get. They will probably see this post and what I have discussed with you all. I am going to upload all my research onto a USB and slide a magnet over my computer's hard drive now. I will reach back with more news after I have found a secure location to proceed with my updates. Until then....
-Colin.
Update 5
So I am currently posting this on a burner phone that I recently bought. I have booked a motel room with cash and I will use their wifi with a VPN. I would like to first express that whoever called me yesterday that I will not stop until I get the answers I need. I am sure with whoever has been reading my recent posts that they wouldn’t like me to stop looking either. I will bring justice for Carly and her grieving mother. I know that the government has something to do with this. I have got some feedback saying that the bridge might have another tape possibly. To my surprise there was and I just listened to it. I’ll replay it for you.
[Play]
“Hello… I don’t have much time to say what I need to say. I recently found something and it needs to be shared with the world. My name is Carly Johnson…”
“They are really close right now… I can see their flashlights through the trees. I am under some type of bridge.”
“I have recently come upon a file that was on a USB which was sent to my house…. Its title is Project Sight and the public needs to be aware of what I found.”
“It has many many documents containing all sorts of stuff including Area 51, The Roswell Incident, and various pictures of these very tall what seems to be creatures. So many classified documents on this file.
“I have made a backup of the file and it is located in my g---
[Cuts out]
Well shit, we finally know what we are dealing with. They brought out the FBI because it is a national threat which is out there on that USB. What was she about to say… she cut out saying something that started with a g but I have no clue. I am going to need help with this one. Please give me your thoughts on where she may have hid the backup. I have a feeling that they will find it before I do. I need to find that USB before it gets destroyed. I am not staying another night at this motel. I am going to switch it up so it is hard to track my footprints. I will be ok with my funds for now because I transferred what I had left in my savings and converted it into bitcoin. Hopefully I don’t have to explain why I did that. Once I am done packing up here and on the road I will proceed with another update.
Update 6
I stopped at a local convenience store near me and got myself some snacks and water for the road. This blue raspberry Slurpee is pretty good right now. I wanted to go to a local library to proceed with my updates but none of them are open because of this whole quarantine thing. I am probably better off in the motels though. I backed up the tape to my USB and set a password on it so no one can access it. I most likely am a current threat to the FBI so I don’t know how long I will have to stay moving. My plan is eventually to bunker down somewhere but until then I need to keep moving. I also have this cheap laptop I brought to access files that I cant on my phone. I was looking more into Carly's assets through some public info websites and such, you can use Whitepages plus to get a lot on someone. You can access background checks and look into someone's past, It is pretty crazy what you can get on someone. I also was looking through her Facebook and found an older post with her dad working on a project car. Looks like one of those storage garages that you can rent. She doesn’t post much. All family related stuff and a couple friends. Guess she kept more to herself. I am curious about when she said it was called Project Sight. Why would they call this file that in specific? Who knows. Do you think it would be a good idea to talk to her mom? Probably not, now that I am thinking of it. The FBI is probably all over her house. Hmm wait a minute, I remember that her mother had a Facebook page. Maybe I’ll send her a message where we could maybe meet up or something in private. She probably would give insight on what Carly said on the tape. I pulled into a parking lot that seems to be pretty empty. I want to try and take a nap and maybe wake up with a new idea or something.
Update 7
Fuck me. A cop just woke me up by knocking on my window…
“Hello officer, is there a problem?”
“I don’t think there has to be one, are you a little tired?”
“Yeah, I pulled over in this parking lot to clear my head and take a little nap.”
“Gotcha, you got any Identification on you?”
“Yes sir, can I grab it out of my glove box?”
“Yes, just no sudden movements.”
“OK, here is my registration and proof of insurance as well as my I.D.”
“Thanks for being so cooperative, let me run your stuff and you’ll be on your way shortly.”
He went back to his vehicle and I don’t know what he is going to find. What if the FBI put a warrant out for me or something?! I am probably just super anxious because of this situation. They want to keep everything top secret so they won't involve the police. He just got out and is walking back now.
“Here you are *hands back documents*.... You're a little ways from home aren’t you?
“Yeah, my Aunt lives out here and I came out to visit her.”
“Alrighty, I don’t see a need to cite you or anything so I’ll leave you with a verbal warning so just try to sleep somewhere else next time … OK? “Thank you again… have a good one.”
Well that could have gone a lot worse. I looked up the mother's address and it is only an hour from me. I am going to call her by the name Catie from now on. I made a Facebook account with this burner and messaged Catie on messenger saying “I know what happened to your daughter Carly… they faked it.” [SENT] Hopefully she sees this soon and we can chat a little bit and hopefully it helps to find that backup.
Update 8
So she read my message a moment ago and responded with “Who are you?” I responded with “Meet me at the Franksville park in 20 minutes, I am here to help not hurt. Please do not bring the police… they covered this up.” I am already parked here where I can see the parking lot but no one will be able to clearly see me staking it out. If the police roll up to the park I will exit through the back. If she comes and she is in a black jeep then I will text her again telling her to go to the bench across from her and wait for me. Hopefully all goes to plan.
[20 minutes later]
Great, she just pulled up and no cops. I messaged her the message and am waiting for her to do as directed. I talked to her for a while, probably a good half hour. I wrote down what I thought were the most important things she said.
“Father was a military officer”
“Dropped out of college”
“Top of her class”
“Public storage garage”
“Police searched Carly's house without proper consent”
“Computer and journal missing”
This was the farthest I have been in this case. Now that whoever is watching just know that I am currently one step ahead of you in every way now. I have developed different plans based on what might happen and every possible outcome and how to counter the bureau. I may not have the man power the FBI does, but I do have more knowledge now. So just know
I am coming for you … I will ruin you.
I am now taking the cellphone battery out and disposing of it. Until the next update….
Goodbye.
-Colin
Update 9
A lot happened yesterday, first of all it was mothers day. I was debating if I should go back to my moms house because someone could be posted out front waiting for me to return. I was wrong and the night went well. I left around 9 pm to find this USB. Someone that wants to remain anonymous direct messaged me and said they thought that the storage unit might be where she put the backup. I looked into it. I knew the number which I will not say for my own protection but Catie gave me the number of the storage garage. She said that she never had the key but she helped enough and that wouldn't be a problem for me. I went to the main office of the storage rentals and bought myself one near Carly's garage. This way I can have access to the property without suspicion. One thing that is really beneficial to having a pass code to the main gate now is that I can come whenever I choose. This place is 24 hour service. OK so now that I have developed a plan on how to get in now, I need to pick her lock.
It should be pretty easy if there are no cameras and if no one is working. I haven't really scoped anything out for assurances but hopefully it all goes to plan. On a side note I have been contacted again by that number, they sent me a picture of my car ... my actual car ... Shit. OK so they most definitely are watching me but that was from last night so I don't know if they are currently. If I do post this post just know that I am safe and have acquired the USB hopefully. I am going to take bolt cutters and a hammer to see if I can just break the tiny lock to get in. I will update you when I am back.
Update 10
OK I am going to choose my next choice of words very carefully. I found what I needed ... what I was looking for, for the last couple of days. I broke into the garage and there was this nice 1976 mustang cobra, what a beautiful car. I turned my phone's flashlight on and looked in the back of the garage. There was this tool box and I looked all through it, but didn't find anything in that. Next, I went to the car and it was open how fortunate ... I looked in the glove box and I found something. It was in this tiny envelope with the envelope saying "Insurance". OK I got what I came for and shut the door to the garage and left. I plugged the USB into my tiny laptop and it came up. First file "Project Sight", I clicked on it and 4 more files came up. 1st "Access point 51 [Classified]", 2nd file "Roswell, New Mexico [Classified]", 3rd file "JPEG File [Classified].
What was on these files I can't really describe. I need a little more time to wrap my head around all this information and figure out what to do with it. The weirdest of them all was the JPEG files, there were at least dozens of pictures that were all super blurry but mostly they all had one similar trait. At least 7 foot tall and a very large round head. They appeared to be a darker gray color and that's about all, The pictures were all in black and white though so that was not helpful. I need to know what to do with this USB. I think I am going to make a back up somewhere and place it somewhere where no one will find it. If these men do come for me I do not want them to win. So I set up some posts that will eventually post automatically within 48 hours of no account activity. I am still posting on a burner phone at the moment. All I ask if I go missing please don't let me end up like Carly. She said that this information needed to be shared with the world. I want to avenge her. The FBI will not get away with this. If these posts get deleted I have set up logs to be saved and they will all be backed up and reposted automatically as well. Nobody can stop that process too.
They know what type of car I drive and where I live. They know I have this classified information and will not stop until they get what they want. I don't want to die. I am scared for my own life and safety of my family at this point in time. At this time I am writing this on my phone, I can see a black SUV parked 4 cars to my left in the Walmart parking lot. It may just be my anxiety but there are two men sitting in the front. I may be dead within the next day or taken. Who put that fucking tape at my dumpster in the beginning? Was it them? Did they watch what I did everyday and find my daily routine and match that to when I would take the trash out? Could they have placed the tape at a spot I could visibly see all on purpose, knowing that I would pick it up and listen to it. All for what though? Why me? What is the point of going after a teenage kid? I might just be going crazy because of all this. I would like to express....
Whatever does happen to me, just know if you do find a cassette tape at the dumpster, don't play it.
Until next update,
-Colin
Note - My automatic posts I have set up go off in the next 48 hours of inactivity of the account. I have hid the USB and a GPS coordinate of where it is hidden will go out to someone that I trust very well.

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.
