Gridcoin "Fern" Release

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.



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.


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.


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



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.

For a more interactive view of changes, click here
In our current world; bordering on financial chaos, with tariff wars, Brexit and hyperinflation rife, you can count on Groestlcoin to consistently produce innovation that strikes to take the power away from the few and into the many, even after a full five and a half years of solid development.
Here is what the team has already announced in the last 3 months since the last development update:

What's Being Released Today?

Groestl Nodes

What am I?

Groestl Nodes aims to map out and compare the status of the Groestlcoin mainnet and testnet networks. Even though these networks share the same protocol, there is currently no way to directly compare these coins in a single location. These statistics are essential to evaluate the relative health of both networks.

Groestlcoin Transaction Tool

What am I?

This is a tool for creating unsigned raw Groestlcoin transactions and also to verify existing transactions by entering in the transaction hex and converting this to a human-readable format to verify that a transaction is correct before it is signed.



Groestlcoin AGCore

What am I?

AGCore is an Android app designed to make it easier to run a Groestlcoin Core node on always-on Android appliances such as set-top boxes, Android TVs and repurposed tablets/phones. If you are a non-technical user of Groestlcoin and want an Android app that makes it easy to run a Groestlcoin Core node by acting as a wrapper, then AG Core is the right choice for you.

wasabi never reconnects to Bitcoin Core and other issues

About a week ago I transferred some BTC into wasabi and queued it for CoinJoining. It has been a very slow process and it still hasn't finished. How long is it expected to take? And is the balance meant to be ground down into lots of 0.1xxx BTC outputs?
The last couple of nights I've left the wallet running only to wake up in the morning to find that it has made no progress overnight. Both times I see "Local Bitcoin Core disconnected" in the stdout shortly after I left it alone and it never reconnects after that. When I try to shut the wallet down to restart it, it just hangs and I have to explicitly 'kill' it.
Here's the output showing how there was a 9 hour gap shortly after Bitcoin Core disconnected:

Other times I see the balance dropping considerably, only to go back up when I restart the wallet.
One time I saw this error, about 'Index out of range':

Should I be making github issues each time I see weird behavior from wasabi, or is it already known that there are lots of problems with it? Am I doing something wrong to be having such an unstable experience with the wallet? I downloaded "Wasabi-1.1.4.deb".

Summary: pitfalls of paper wallets

Pitfalls and solutions of paper wallets

Creating paper wallets:

Problematic action: Create a paper wallet on a paper wallet service website without disconnecting from the internet. Reason: It's extremely insecure for many reasons, some being 1) the website is hacked with generated private keys sent to the hacker; 2) there may be malware in the browser or in the operating system that sends the private keys to the hacker. Solution: The bottom line is to disconnect the internet before creating the paper wallet. It's not secure enough because 1) the malware can save the private keys and wait for internet connection to send them out; 2) the malware can interfere with the generation process itself and give you a private key that is already known to the hacker, which is called backdooring the random number generator; 3) the private keys may exist on the hard disk therefore may be extracted by malware or after the computer is disposed. Better solution: Download the paper wallet app from an online computer. Copy it to an offline computer via a flash drive. Run it from there. Best solution: Use a live operating system, such as a Linux live CD, to run the paper wallet app. This is not ultimately bullet-proof, especially for high-value targets, because there exist malware that can hide in the BIOS and firmware of your computer and can infect your live operating system. It should be secure enough for average Joes.
Problematic action: Create a paper wallet without serious verifications. Reason: There may be incompatible issues with operating systems and browsers. Solution: Run tests on various operating systems and various browsers before putting BTC in. Make sure the generated private keys are identical. This applies to regular paper wallets and BIP38 paper wallets. Make sure the decrypted BIP38 keys are correct.
Problematic action: Create a brain wallet created by bitaddress.org or other brain wallets without key stretching. Reason: It has been proven insecure. Solution: Use WarpWallet or other brain wallets with key stretching, e.g., scrypt, bcrypt, sha512crypt, pbkdf2, and so on.

Printing paper wallets:

Problematic action: Use a wireless printer. Reason: It's insecure because wireless networks are insecure. Solution: Use a wired printer.
Problematic action: Use an advanced printer, which has internal storage, such as a hard drive. Reason: It is insecure because the private key of the paper wallet printed may be stored on the internal storage, therefore may be recovered if the printer is sold or scrapped. Solution: Use a dumb printer. Or keep the printer locked up and never sell or scrap it. Or smash the printer, including and especially the internal storage.
Problematic action: Leave the printer open for other people to access after printing without turning it off. Reason: It's insecure because the private key printed may still be in the memory of the printer. Solution: Turn the printer off after printing.
Problematic action: Leave the computer untreated after printing. Reason: It's insecure because the printer driver and/or operating system may be keeping copies of the documents you print in some sort of "spool" or print queue. Solution: Use a live operating system, such as a Linux live CD, to print.
Problematic action: Use a shared printer (at work or school, for example). Reason: It's insecure because 1) the printer may have a glitch and someone else may get your printouts; 2) the printing jobs may be centrally logged. Solution: Don't. Use your own printer.
Problematic action: Use a printer to print the private key or the QR code of the private key. Reason: See above. Solution 1: Don't use a printer for private key stuff. Hand-write the private key. Hand-draw the QR code if you and the helping checker are patient enough. Or ignore the QR code since hand-drawing the QR code of the private key may be too time-consuming. Double check. Then check it again, preferably on a different day. Get someone you trust to check it. Then get him/her to check it again, preferably on a different day. (Testing the private key in a wallet app can make it sure. But it comes with risks.) Solution 2: Don't use a printer for private key stuff. Use brain wallet. Write down the passphrase and the relevant information, e.g., the name of the tool used, e.g., WarpWallet, and the instructions. Store it the same way as a paper wallet. Save and store some copies of the tool, in case the future versions become incompatible. (There are pitfalls for creating man-made passphrases. It is beyond the scope of this post. In a nutshell, don't create the passphrase (solely) with your brain, and don't keep the passphrase (solely) with your brain.)

Spending from paper wallets:

Problematic action: Import a paper wallet private key into a wallet app, then spend directly from the paper wallet address.
Mistake: Expect the paper wallet automatically receives/holds changes, similar to a real-life wallet, which may not be the case. Reason: Early wallet apps didn't handle the changes correctly. The changes became the transaction fees of the miners. There is a misunderstanding of how Bitcoin works. There is no account balance of any kind in Bitcoin. There is only Unspent Transaction Outputs (UTXOs). The receiving addresses of changes, which will become the new UTXOs, must be specified when BTC is spent. Otherwise, the changes will automatically become the transaction fees. This depends on the implementation of the wallet app, which should not be trusted.
Mistake: Think nothing is wrong if changes are handled correctly. Reason: It's called address reuse, which is not recommended in Bitcoin because 1) it reduces anonymity of both the sender and all the consecutive receivers; 2) it reduces the security by exposing the public key, which is vulnerable to quantum computing. Addresses are hashes of public keys, which are safe from quantum computing.
Mistake: Destroy the paper wallet after it's imported into an HD wallet, thinking that it has become a part of the HD wallet and it's safe to destroy because the master seed of the HD has been backed up. Reason: It is not a part of the HD wallet. If the paper wallet (the paper) is destroyed and the app is uninstalled, the BTC is gone even if the HD wallet is recovered from its master seed.
The right way: Spend (transact) all BTC in a paper wallet to an address of your wallet app. It is called "sweeping", which is completely different from importing the private key. Spend BTC from there. After all the spending is finished, create a new paper wallet and transact all the remaining BTC to it. Store the new paper wallet. Keep the old one for future reference, or destroy it if you don't want the trace.

Destroying paper wallets:

Problematic action: Destroy a paper wallet after it is used. Reason: You may need to prove you had control of that address some day, e.g., for taxation purpose. In the case of a chain split, you may have a balance on the other chain. Solution: Don't ever destroy a paper wallet. Keep it on file. Mark it with the relevant information, e.g., "Used in April 2017". Unless you don't want to be tied to the address.

Pitfalls not specific to but more likely happen to paper wallets:

Problematic action: Google a famous wallet app, click the first link or the sponsored link, download/install it, and use it, without serious research. Reason: It's insecure because the wallet app may be a scam. Solution: Do thorough research prior to deciding which wallet app to use. Find the official site prior to downloading/installing it.

How to get free BCH, BTG, BTX, CLAM, SBTC, BCD, BTP and BTN and cash them out

*EDIT: a new version of this guide, multilingual and featuring a wallet checker (input your IP, see what you can fork and how much it is worth) is available at https://cryptodom.org *

Dear you all! I have been following closely the airdrops and especially the forks of the last month or so, and I am proud to announce I have just successfully claimed (&cashed) my BTF and my BTW. After claiming (&cashing), in order, BCH, BTG, BTX, CLAM, SBTC, BCD. Like most of you, if you are reading this, I am still looking for a solution for B2X, and I have also claimed but have so far been unable to cash out BTP and BTN.
*EDIT: Now created, transferred and cashed B2X, BTP and BTN - See EDIT at the end of the post
While doing all this, I did notice a couple of things: 1- It is extremely hard to find proper information about the forks (here’s a good starting point though: https://btcdiv.com/ ) 2- There are significant security risks involved with these procedures
I will try my best to try and explain you what I did, while also offering a service to do it for you for a fair fee if you still can’t do it/don’t feel safe doing it.
Here we go:
INTRO Before you start this, ask yourself a very important question: do I understand what I am doing? If the answer is YES, then you should have your private keys and you are good to skip the intro. Let me try to make this short and easy: you have some bitcoins, somewhere. In some cases you have direct access to the keys (LEDGER*, blockchain…), in other instances you don’t (crypto held on exchanges). If you DO have access to those keys, you need to do two extremely important things:
1- Write it down 2- Move your whole balance to another wallet/address
Please note that if you fail to implement number 2, any hacker claiming to “do this for you” will steal your bitcoins. As simple as that. No matter what you are claiming, taking the risk won’t be worth it, so MOVE YOUR BITCOINS from the address you stored the private keys of.
Please note: how much you can claim depends on how much was on the wallet you will be sweeping from at the time of the fork. Considering that the blockchain is free for everyone to explore, you can figure this out easily. In most cases, a blockchain explorer could help you know how much your keys are worth before you sweep them. Be aware that the maths are MORE OR LESS these: are you holding 5+ BTC since 2017 (the further the better)? Congrats, you are in for some real money. Conversely, if you have been holding <1 bitcoin you are probably just losing your time as whatever you’ll get won’t meet the thresholds for minimum transfers anyway (unless we are talking BTG and BCH, good luck with that).
Download COINOMI on your android (https://play.google.com/store/apps/details?id=com.coinomi.wallet) Open coinomi and set it up (create a wallet and write down details, thank yourself later) Now add BCH, BTG, BTX, CLAM as coins to your wallet and then claim them one by one in the same order To claim, go inside the coin’s screen and click the three dots on the top right of the page —> Sweep wallet (repeat for all coins)
Download these two apps on your android: BITHER, BITPIE (https://play.google.com/store/apps/details?id=net.bither / https://play.google.com/store/apps/details?id=com.bitpie) Open and setup both apps (create a wallet and write down details, thank yourself later) Now open BITHER and click the settings icon (top right), then ADVANCED OPTIONS —> IMPORT PRIVATE KEY —> FROM PRIVATE KEY TEXT (Important; use the "FROM PRIVATE KEY TEXT" option, NOT the one with the BITHER key!) to claim, go ADVANCED OPTIONS —> GET FORK COINS and take it from there (your private keys should have been imported and should show you how much they have on them (SBTC, BCD, BTF, BTW, BTP, BTN) At this point, all you need to do is to tell BITHER to transfer the free coins to a corresponding BITPIE address
PART 1/c - CLAIMING - DIG WALLETING SERVICES (UNTESTED) (BCH,BTG,SBTC,BCD,BTF,UBTC,B2X,BCX) Today I also chanced upon a site ( https://bitcoinforks.io/ ) , which gives a nice picture of the forks. Apparently, they also have an automatic “digger” that charges 10% to transfer the forked coins to a (fork) wallet of your choice. I have tried to test with UTBC but it told me I had no coins, which might actually be true. Some users on bitcointalk report success, so feel free to try with small amounts and see if it works for you. Please note they take a commission on the CLAIMING part, while, at least to my understanding, COINOMI and BITHER do not (even though BITHER forces you to transfer to a BITPIE address).
If you got this far and you now have a balance in any of the coins above, you should immediately transfer the “real” coins (BCH/BTG) out to a reputable exchange/wallet (not that I do not trust Coinomi but you never know), and try to convert the rest to a proper coin before moving it in bulk to an address of your choice. Apart from Coinomi, this is where it gets tricky. A lot of those coins are only listed on some obscure Chinese exchanges and it’s hard to even understand what the value of the coin is since it varies widely from one to the other. Some of those coins MIGHT one day make it to a major exchange, granted, but personally I couldn’t wait to dump all of them (I regret doing so with BTX though). So I went through the whole verification/blind trust process required by the shady sites and… I got my free coins converted into actual BTC/LTC. On that note, it must be noted that not content with applying daylight robbery fees the exchanges also require a minimum amount for you to be able to withdraw (and a verification with ID in some cases). Here is what I did and how it went: I got accounts on GATE.IO - BIT-Z.COM - BTCTRADE.IM* and somewhat made my money get out of there and safely into my ledger. Would I recommend those exchanges? Well… Personally I have nothing but praise for GATE.IO and BIT-Z.COM - They accepted my transfers speedily and I could trade and withdraw easily - no verification needed. As for BTCTRADE.IM, it did require verification and is by far the slowest of them all, but since I got money out (in the end) I can’t complain for the time being.
Note: problems getting verified with btctrade.com? Read this : https://www.reddit.com/BitcoinAirdrops/comments/7qqxv4/guide_claiming_and_dumping_bitcoin_faith_btf_fo
PART 3 - DO YOU NEED HELP? Some of you will laugh at my deal, since they are smart, tech savvy and are running several nodes of all the existing forked chains from a computer in their basement, interacting with the exchanges via API only. However, I expect the vast majority of you to be able to arrive to part 2 but then get stuck at moving the money to the Chinese exchanges. Let me reiterate that they worked for me, so I’d generally recommend them. In case you do NOT want to try and get through that yourself, I would like to help! Here is how:
PM to get in touch Transfer the forked coins to my bitpie/btctrade/gate.io/coinex addresses Wait for me to receive, transfer to the exchange, change it into LTC/BTC/BCH and send it back to you, minus a fee**
Please note that some transfers take time, and this is independent of me. I will, however, send you all the transaction details as I do the operations so that you can track it yourself.
*QUICK REMINDERS: BTCTRADE.IM withdrawal fee: btc: 0.001 BCH: 0.001
BITPIE EXCHANGE: BTF/BTW need 120 confirmations to transfer from bitpie to the exchange (my first BTF transfer took nearly 32 hours, BTW took 20)- you will be able to monitor that from your own bitpie wallet and you can ping me when it hits the magic number.
GATE.IO and BIT-Z.COM are faster (10+ confirmations I think) so I should use them if possible (depending on coin deposit availability).
**FEES You can check the value of the coins on the exchanges to get a rough idea of how much your coins are worth - I will send you all the transactions anyway but please do your research. Sometimes coins have high value on exchanges where deposits are not accepted, for instance, and tend to drop sharply in value as soon as the gates are opened. Depending on how much I will be moving for you, these are my fees: 5% (>2000 USD worth) 10% (between 500 and 1999 USD worth) 50 USD (<500 USD worth)
Oh and one last thing… Why would you trust me? If nothing, for the simple reason that I honestly told you exactly HOW to get the forked money and through which exchanges I cashed it out. I simply wrote the post that I wish I had found when I started doing this, and I hope that some of you will be lazy enough to use me for the most complicated part of the deal, giving me something in the process. If I get nothing out of it, I will be fine and happy to have spread some knowledge anyway!
EDIT 1 - 12:48 GMT 25-01-2018
I have tried DIG WALLETING (affiliate link: https://dig.walleting.services/#/aff/o5YP75ALDORdaAbmrJJx NON affiliate link: https://dig.walleting.services/#) and they did a great job. The hard part, as usual, was to have a proper address to transfer them to. Anyway... Now claimed and cashed UBTC as well as B2X (btctrade.im & exrates.me respectively - thanks #hniball)
Bither & Bitpie opened the exchange (on Bitpie). The process is a bit convoluted and you need to transfer the money in and out of the "pie bank" in order to dump. Prices are tanking fast and it takes hours to even transfer the money. Astronomical fees, but it worked and I cashed out BTP and BTF in BCH. Fun fact: I thought I had 5k USD in BTP (according to the BITPIE wallet). They eventually turned out to be 0.05 BCH (Thanks, BITPIE exchange). Reality check...
Given what I know now, I'd advise to use DIG WALLETING to send the forkcoins directly to my BITPIE addresses if you want me to do it for you (or send me the seed once you have emptied the wallet, that would work too). But, as usual, you are more than welcome to do it on your own.

BiteBTC exchange has robbed me 370 000 ReddCoins

BiteBTC exchange has robbed me 370 000 ReddCoins
I found old hard drives that were in the cell and accidentally discovered that I had a wallet with ReddCoins - the cryptocurrency of the Reddit community. Due to my inattention, I lost over 90% of its contents. That's why I decided to warn everyone who would like to register on BiteBTC.com. This exchange market is just plain crooks, and the number of victims can be counted in at least hundreds of people.


Swapping ReddCoin with Ether

2019-05-02 Thursday

I was looking for an exchange market to send there ReddCoins I mined and swap them for Ether.

In the years 2014-16 I mined many altcoins like DogeCoin, LiteCoin, LeafCoin, SolarCoin, QuarkCoin and other unusual. I used various exchange markets and never got cheated. I always checked before sending my coins to anyone. This time I checked too few sources.

I found information about BiteBTC.com that there I can exchange pairs RDD/ETH on both website: CoinMarketCap.com and CoinpaPrika.com.

At this time on coinmarketcap.com was information about fire building in company in Singapure. It's been over a year since the event, the stock exchange is still functioning and is still on CoinMarketCap.com and CoinpaPrika.com, I decided it was not SCAM.

I registered with the Full KYC procedure, i.e. I sent a personal ID scan and a regular letter on which my address is displayed.

Confirmation that the account is fully active I received after minutes.

Sending ReddCoins to BiteBTC

2019-05-03 Friday

I send 120k RDD on BiteBTC.com wallet.

After exchanging them for about 1 ETH, I made the procedure for withdrawing funds to my wallet and sent a request to the support team how long I’ll be waiting for approval of the withdrawal.

I received an answer after minutes.
This answer convinced me and I decided to send more, it was 350k RDD.

Total I send 470 000 ReddCoins.

Then I exchanged the major part for Eteher and I made the next withdrawal procedures. In total, I setted withdrawal around 4.5 ETH (I have no confirmation in any form).

Account temporarily blocked

2019-05-04 Saturday

I received an email from the support team that my account was temporarily blocked and to unlock I’ve to send additional information about the funds I sent to BiteBTC.com.
From now, contact has stopped.

The support does not respond to any e-mail sent from me, and I sent them lots of e-mails.

My account in part is active, but I don’t have access to Ethereum, which I wanted to send.

Subpages like Verification, Balances, Orders history, Trades history, Transactions history, API keys, Settings czy Coin Redistribution are blocked and only you can see Profile page.


On the subpage where you can exchange the cryptocurrency, I can see the rest that was after setting the withdrawal procedure.

There are 0.14102608 ETH and 93260.01418987 RDD. However, I can not exchange, the message pops up that the account is not fully activated.


I started looking for more information about this exchange and found other victims on Telegram groups.

A cryptoforker's guide to free money - Part 1 (The holy ymgve script + what and where to exchange)

EDIT: a new version of this guide, multilingual and featuring a wallet checker (input your IP, see what you can fork and how much it is worth) is available at https://cryptodom.org

Hello my lovely forkers!
A while ago I made a post A cryptoforker's guide to free money - Part 2 (Coinomi, Bither, Bitpie, Walleting Services) where I explained how I used a combination of COINOMI and BITPIE (together with DIG WALLETING SERVICES) to get hold of most forked coins - And then how I sold them (main sites used: GATE.IO / BTCTRADE.COM / BIT-Z.COM / EXRATES.ME / COINEX.COM). Please refer to that for the instructions regarding Bither and Coinomi.
QUICK NOTE: If you are a seasoned forker, just look at point 4 and see if your pokem… I mean fork coins collection is complete :-p / If instead you are a total newbie, remember you can just do the “PREPARATION” part and then claim through DIG WALLETING (affiliate link: https://dig.walleting.services/#/aff/o5YP75ALDORdaAbmrJJx NON affiliate link: https://dig.walleting.services/# ) if the process is too hard/long/risky - these guys are reliable and provide a great service, especially for those who have a plethora of transactions and would need to hunt down every last key manually - they have a Reddit, too: you can reach them at Walleting_Services .
BEFORE YOU START: What is a fork? Is it really free money? Imagine you had a bank account at BTCbank and a card for it. Tomorrow BTCbank splits and half of its branches become BTC2bank. Nothing changes for you as a client of BTCbank, however there is something you can now do. You can move your money from your BTCbank account to a new BTCbank account, in practice making the card for your former account useless in the BTNbank branches but… NOT IN THE BTN2bank branches! So you can go there and get the equivalent of what you had in “free” money. Nothing illegal, nothing shady, no bugs or exploits: it’s all there by design. Keeping with the example though, it should be specified that you must have the “card” of your BTCbank, which in this case is a private key. If you have your BTC stored on papehardware wallet or anywhere else where you are in direct control of your private keys, well done! Those keys are your BTCbank card(s). If, on the other hand, you held your money on an exchange (Binance, Bitfinex, Bittrex, you name it), then your only chance is to wait and hope that the exchange decides to support the coin and gives you your share. It’s not impossible but it introduces a middleman. It’s like you are asking your uncle to have an account in his name at BTCbank and there is no guarantee that uncle will go to a new branch of BTNbank2 and use the card trick to get the free money and give it to you, no matter how much you ask him to. He could do it, he could not: it’s uncle’s call.
PREPARATION: First of all, a question: are you after the fork money to exchange it yourself or do you just want to claim it but want someone else to do all the exchange part for you? If you want to squeeze every last bit out of it, get ready to sign up to a few Chinese exchanges! You might as well do this now before you start, otherwise you’ll get stuck at the cashing part. Same goes for the script. No target address, no script. I warned you :) Anyway, here’s the list: • GATE.IOBTCTRADE.IMCOINEX.COMEXRATES.METRADESATOSHI.COMBIT-Z.COM
My personal favourite is GATE.IO, despite the 60 confirmations (up to 14 hours), but they all helped me one way or another, and most importantly they all allow withdrawal (BTCTRADE.IM wanted verification papers, the others didn’t). Also, make sure to have Coinomi, Bither and Bitpie installed on an Android phone.
STEP 1 - THE GOLDEN RULE Just like in the previous post, let me start off by warning everyone: what are you about to do is dangerous. You could lose your bitcoins. Are you scared? You should be, cause the threat is real. Nobody wants to lose 1 BTC to try and claim a few tens/hundreds of dollars, right? So, first and foremost, make sure that you MOVE your coins from wherever they are (ideally, an offline wallet like a ledger or a trezor), and then, once the wallet is empty, feel free to play around with its private keys, that will hopefully show some transferrable balance at the time of the fork.
STEP 2 - GETTING YOUR KEYS - https://iancoleman.io/bip39/
For getting the keys, this is your number one option - with an offline version for paranoid available, no less. Use the seed (those 24 words in the case of ledger, for example) and after the calculation go get your keys in the chart at the end of the page. In case you have segwit addresses or special scenarios (like a wallet with a lot of operations over a long time), getting the keys, or the “right” keys, might take a while. Anyway: let’s look at the first line of the chart. In the first column you will find the address: copy and paste it onto https://blockchain.info/ and press enter to get the transaction history for that given address. Let’s suppose for the sake of this example that our address shows 2 transactions: one inbound for 2 BTC 1 year ago and anther one for the outgoing BTC 5 minutes ago (because before we started this we DID move them out, right?!?). What that means is that at the time of the forkS (in this case we’d get money from most of them) we had 2 BTC on that address. Great, so it’s loaded, and we need its key. Let’s go back to the chart on line one and let’s have a look at the third column: this is our private key. We will use it later to sweep or import in the various method outlined.
STEP 3 - THE SCRIPT - https://github.com/ymgve/bitcoin_fork_claimer
If you have ben around this subreddit long enough you surely read about the script… And spared a tender thought for ymgve who made this possible. Yet, no one really explains properly how to use it. Unfortunately I do not have the time to explain how to get python installed and running on a machine, you will have to figure it out on your own. Same goes for the fact that you might need to write “py” or “python” before the actual “claimer.py (…)” command. Let’s say you somehow get ready to run the script - now you do have a series of examples on the github page, but they are not so easy to understand for the uninitiated. Here is the relevant quote:
In blockchain.info mode it uses the blockchain.info API to query and validate information about the transaction you're spending from. This only works for transferring/claiming coins that existed on the BTC main chain pre-fork. SYNTAX: * claimer.py * EXAMPLE CLAIMING BTG - BITCOIN GOLD: * claimer.py BTG 4adc4(...) 5K2Y(...) 1HKqKTM(...) 1aa5cm(...)*
Let’s have a look at the example and remember what we did before in the “preparation” and “getting your keys” sections. In the former, we signed up at the exchanges so we now have the relevant deposit addresses, right? So let’s say we want to get fork XXX : let’s look for a deposit address of XXX and let’s call it DEPOXXX - Next, (hello, blockchain.info – here’s my wallet address from column one) we’ll look for the transaction ID (TRANSXXX) of the wallet (WALLETXXX) we have the private key of (PRIVATEXXX). We have it all now, so our script will be:
Admittedly, there is a more complicated method for FBTC and also some kind of manual mode to transfer just parts of the sum and set the transaction fees, if you need those, good luck :)
Also, I was contacted by ottoteixeira who reminded me he created a very useful script (I actually used it during my first attempts) - What it does is to create the scripts to run on ymgve's script. A script for the script, right - sounds complicated but it actually makes your life easier once you understood what you are doing. Give it a try: Otto's script - (requires minimal coding skills to edit the file with your own data)
BCH/BTG - Claim with Coinomi, move to Binance
SBTC/BCD - Claim with Coinomi, move to gate.io
CLAM/BTX- Claim with Coinomi, move to bit-z.com
BTP/BTN/BTW/BTF - Claim with Bither and exchange with Bitpie (move them to the bitpie bank once they cleared to be able to trade on the exchange)
B2X - Claim with script straight to exrates.me
BPA- Claim with Bither, no exchange accepting deposits so far
BTW - Claim with Bither, move to btctrade.com
BPA - Claim with Coinomi, no exchange accepting deposits so far
UBTC - Claim with script, send straight to btctrade.com
CDY - Fork of BCH, untested but should work with script straight to bitpie
BTV - Claim with script straight to coinex.com or bit-z.com
LBTC - Claim with the online wallet (http://lightningbitcoin.io/ ) (download, run, sweep keys) - can be traded through cryptosnake
LCH - Claim with online wallet (https://litecoinca.sh/#download ) (download, run, sweep keys) - can be traded on tradesatoshi.com
BTCP – I haven’t claimed it yet but some people seem to have made it. To keep up with the news, I follow the #bitcoinadrops discord channel, they talk about it and they are hilarious ☺
UPDATE: Can be claimed with Coinomi (only non segwit though, so I can't test at teh moment). Many successful reports of claiming already. First price I've seen was 0.002 - seems low compared to the hype. I was hoping for 0.02 :-p
BCK/BTSQ/BTT/WBTC - Claimable through the script apparently, I haven’t tested cause I have no target address
BTH/BCX - I am yet to find an address where to send them to :(
STEP 5 - FINAL NOTE: Oh no! After 2 days of python, apps, furious coin creation and shady Chinese exchanges you are done. Bonanza is over. Not quite! Here is a little reminder of where to find the info you want and need about the forks -
• cryptodom.org - start from here, always
BitcoinAirdropsTrades - end up here if you are the kind of person who wants to pre trade forks the moment the wallet hits Github :)
And that is all, folks :) Feel free to ask me questions if you are stuck or something is not clear, and I will try my best to answer you. If I helped you, feel free to tip your humble fellow forker here—>

Oh and one last thing… I did help 4 people to sell some of their forked coins, two of them from Reddit. They are binsone and whospumpin. A lot of people are helping, I know… camku Playboy_BTC cryptosnake eliteluxurytrades - Personally I used cryptosnake twice and he was fair and square with me: honestly, all these guys can do some coins I do not handle (LBTC / LCH and even BTCP) - but hey, I am still your favourite one cause I showed you how to do it yourselves, no? So if you are being lazy, let me work for you and let’s share your profits at the usual rate of 5% (over 2k) / 10% (less than 2k) commission :-)

Effective mining with Barrenero

Hello !
I want to share with you the project I've been working on during last months: Barrenero.
Just when I began to mining cryptocurrencies I tried to build something to improve robustness in mining, providing a real-time data and status checkers for my miners.
After this, I found that current miner software is in a continuous evolution, so I'd need a proper method for updating my miners, easy and stable.
Due to I'm mining with some mates, I chose Telegram as our communication channel, so I use it to also interact with our miners, and share the status, information and so on.
What is Barrenero?
This projects aims to create a platform to develop and use cryptocurrency miners such as Ether, Storj... The main goal is to provide a flexible and robust set of services and tools for effective mining cryptocurrencies and performs real time checks over these miners.
Code repository can be found in this repository.
The full documentation, including installation and use instructions, can be found in readthedocs.
Barrenero consists of following services:
To Do
I'm the only developer working on this project and I'm spending much of my free time on it, so if you find it useful there is many ways to help. This project is free and open sourced, you can use it, spread the word, contribute to the codebase, star it in GitHub and help us donating:

Bitcoin.com Wallet / Paper Wallet

It would be cool if in the Bitcoin.com wallet would be a balance checker for the paper wallets.
I would like to scan the paper wallet with the camera and see the balance.

App to check paper wallet balance

A while ago I made an app initially just for myself to quickly check the balance of my paper wallets. I have now made it available on the app store (iPhone): link

What is the most efficient way of checking the balance of 10k+ addresses without having a full copy local? Or can I rent out a full node?

I am currently running a pywallet --recover on the entirety of my mac hd that was used since 2013. i previously scanned stuff like the windows VM i used most of the time and a timemachine image from late 2013 and was able to check the balance by tediously grepping solely the addresses into a newline seperated file with only addr's and used the unix split function to create 8 different 1k lists.
I would then import these as watch only into electrum but even with only 1000 electrum takes a really long time to sync (and as far as i can tell theres no log file to allow me to indicate progress. my network monitor often shows no data transfer leading me to believe that electrum is quitting querying)
I would like a solution that is both stable and efficient. You could query online api's but they rate limit real fast and even utilizing multiple ones, you're bound to hit the limit fast on 80% of them pretty quickly.
Also keep in mind that every bitcoin private key has both a compressed and uncompressed address so while pywallet may say 100 keys, its 200 addresses to check.
I also would like to be able to check this every once in a while to see if any of the addresses have seen new activity. Maybe every month or so, so i'm willing to wait an hour to do it but I would like to have some notion of progress and no ambiguous malfunctions like i experienced with electrum.
What I have used so far (and some might find useful for smaller amounts)
Does anyone have any solution? Is there a way to download the current state of the entire network address balances? Don't need to be cryptographically sound like building up a db or something because i can check it via third party. Having a list of all addresses with balances would allow for a grep that I could run overnight. While it probably would take a while, at least theres always going to be progress and one can tell where they are at on their list.
Side question: is there a way to convert hex keys en masse (or wif if it takes the extra step of converting back to hex ) to litecoin? I'm going to assume that some of the keys recovered by pywallet are litecoin keys. I would then need the same process for the ltc network which I imagine would be even tougher.
If I find some cash (which I am optimistic about) I will send you 50$ for linking to a solution that fits my needs to all above. At minimum I will pay 25$ even if theres no cash on my end.
