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.

Instructions
Step 1: Go to https://reinproject.org/bitcoin-signature-tool/ (click Bitcoin QT)
Step 2: Go to https://paste.debian.net/1148565
Step 3: Copy the message without quotes
Step 4: Copy wallet address and digital signature (there are 144 pairs to choose from)
Step 5: Go to https://www.blockchain.com/explorer
Step 6: Copy the wallet address and click enter to see when the first transaction was made with that wallet (all from early days of Bitcoin)

What does this prove?
  • It proves someone else has private keys (passwords) for wallets Craig Wright claims to have access to in the court case (Craig may not even have access himself, although he claims he does). This means he either lied in court (purjury) or need to provide evidence he actually has access to these wallets too.
  • This proves someone involved in the early days of Bitcoin (mathematically verifiable) thinks Craig Wright is not Satoshi.
  • This does not mean Satoshi signed this message (it could be though). It does not matter anyway, we are all Satoshi.
Note: DO NOT COPY YOUR OWN PRIVATE KEY ONTO ANY OF THESE WEBSITES.

How-to: setup your multisignature Cold wallet in Bitcoin Core 0.20 (highest security setup)

Last release of Core is amazing !
The main new feature is sortedmulti descriptor. This allows you to import your multisig setup in Core almost as if it was Electrum when combine to the new PSBT export in GUI !
As it needs command line and some weird checksum, you also need to input very long command in the console and if you made a mistake, you cannot copy the last command you made. So take your time when the commands are long to check everything and don't miss anything, use copy paste before validating the long command. You only have to do this once fortunately :)
I detail here how you do it with a k of n setup, good luck:
And you are DONE ! You should get the exact same addresses than Electrum and you can created receiving addresses in Qt ! To send money, just go to the send section, use the new coin control feature and export a partially signed transaction. You can use HWI or Electrum to sign it with your hardware wallets !
Notice: You can import more or less than 2000 addresses of each type. If less, blockchain rescan is faster but you may need to redo what we have done here later when all addresses will have been used once. If more, it is the contrary.

You now have the most possibly secure setup in one software: multisig with hardware on the full node wallet. When Bitcoin Core 0.21.0 will be out, we will also have native descriptor wallet so maybe we will have HD version of this. But for now, this is the best you can do ! Enjoy :)

P.S. : if you like doing things in one shot you can do the last two steps in one big command: importmulti '[{"desc": "wsh(sortedmulti(k,[path1]xpub1.../0/*,[path2]xpub2.../0/*,...,[pathn]xpubn/0/*))#check_sum0", "timestamp": birth_timestamp, "range": [0,2000], "watchonly": true, "keypool": true}, {"desc": "wsh(sortedmulti(k,[path1]xpub1.../1/*,[path2]xpub2.../1/*,...,[pathn]xpubn/1/*))#check_sum1", "timestamp": birth_timestamp, "range": [0,2000], "watchonly": true, "internal": true}]'

Make your own stakebox. Ultimate beginners guide how to compile any wallet on AARCH64 (Raspbery pi and other SBC)

I contemplated to wrote this for a long time, so it's finally time.
As you know a lot of altcoins uses PoS (Proof-of-stake) way of "mining" coins. Which basically means, that you hold coins on your unlocked wallet and you are receiving stakes as a reward. This requires very little power and it can bring you a lot of rewards, at just 10W from the wall.
So first I am using latest Raspbian on RPI4B 4GB in this example.Setting up Raspbian is not part of this process since it's very well documented. I recommend to change user from pi to something else due to security concerns and you can also do other stuff just search "security Raspberry PI" and you find a lot of articles, but this is not the focus of this guide.
I know there are a lot of guides on the internet, but I am using like 5 sources, so it's compiled what other people wrote and some of my research.
I am using AnyDesk insted of SSH or VNC server, because it works it's ligthweit and it just works.
So after you see the gui of Raspbian, just launch terminal (CTRL + ALT + T) and do basic thing:
sudo apt-get update && sudo apt-get upgrade
Than press Y and let it run, after is finished, we need to prepare so dependency packages. Since most of the wallets using Berkeley DB 4.8 we need to obtain it.
So in terminal wrote:
cd cd Downloads wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz tar -xzvf db-4.8.30.NC.tar.gz cd db-4.8.30.NC/build_unix ../dist/configure --enable-cxx make sudo make install 
So wait unti it's finished and than you can delete files in Downloads folder in gui or use:
sudo rm -r [folder] 
So next thing we need to install some libraries.
sudo apt-get install git build-essential libtool autotools-dev autoconf pkg-config libssl-dev libcrypto++-dev libevent-dev libminiupnpc-dev libgmp-dev libboost-all-dev devscripts libdb++-dev libsodium-dev 
And pres y and let it run. After that another set of libraries:
sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler libcrypto++- dev libminiupnpc-dev qt5-default 
And then again pres y and let it run. Some wallets need older version of libssl1.0-dev, so for for safe compiling we install that as well:
sudo apt-get install libssl1.0-dev 
Pres y and let it run. Warning don't use sudo-apt get autoremove, since it would wipe this package, since it's old.
Next thing we are going to obtain Bitcoin PPA filest, which can be done like this.
cd /etc/apt/sources.list.d/ sudo nano bitcoin.list 
Paste this in there:
deb-src http://ppa.launchpad.net/bitcoin/bitcoin/ubuntu artful main 
And CTRL+X and than y, then do this:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv C70EF1F0305A1ADB9986DBD8D46F45428842CE5E sudo apt-get update 
So now we are ready for compiling. So we are going create folders. CD yourself where this folder should be situated, if you for example have plugged in some external drive. Then:
mkdir Crypto cd Crypto 
And then we have to choose wallet which you want to compile. I am choosing Streamies (STRMS) as an example, since it's pretty good coin for staking. So:
mkdir Streamies cd Streamies 
Then go to the github page and click on the green button on the left and click copy to clipboard, which gives you git link.
git clone https://github.com/Streamies/Streamies.git 
Watch the output folder which it creates, it's stated in the first two lines and copy then by highliting the text and CTRL+SHIFT+C copy it to your clipboard.
cd Streamies (this is that git created folder) ./autogen.sh ./configure CPPFLAGS="-I/uslocal/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/uslocal/BerkeleyDB.4.8/lib" sudo make (this could take hours) sudo make install 
And you are done, files is going to be in folder /uslocal/bin (DO NOT delete git created folder, because you are going to need it for faster compiling, when wallet get's and update.)
cd /uslocal/bin 
Now you can list files by:
ls 
And then you can copy/move them where ever you want by using:
sudo mv * [destination full path] 
Let it run and go back to folder where you move those files.
sudo chmod +x streamies-qt (since we want to run wallet) 
In most cases compiled files are going to in format of "shared library" so we need to create script to run it. Open up a text editor from gui or through nano. And paste this to that file:
#!/bin/bash ./streamies-qt 
And save it as a sh file, for example run.sh. Then we need to make it runnable so:
sudo chmod +x run.sh 
Now to run it, it's just:
./run.sh 
And here we are glorious GUI wallet appears and you are done, you can paste blockchain, wallet.dat from other sources, so this migration is pretty easy and you, if you have it on for exaple flash disk.
So this is basic how to compile QT wallets on AARCH64. I am running 7 wallets, 2 of those are Masternodes and RPI 4B 4GB would handle way more, I am at best on half of my RAM.
Some wallets need more package, but it's not much of and issue, since compiling stops and you just copy paste nape which is missing put it in the google and add "apt-get" after the name of package and you are going to see, what is the name of the packages so it can be retreived from package assinstant aka apt-get. So basically:
sudo apt-get install [package name] 
Then press y and again wrote:
sudo make 
This process is going to continue where it was left off, so nothing is going to run from beginning.
Updating wallets is basically exactly same, just repeat steps from "git clone" and after that proceed as it was written above.
So I hope this helps some of you, to use this at home and not on some VPS, if you are anxious as me, to host my wallets on remote server.

#Reddcoin ($RDD) Core Wallet Release 3.0.1 - PosV v2 SuperMajority Consensus Upgrade at 45.6% - Required Upgrade

Reddcoin (RDD) Core Wallet v3.0.1 - January 09, 2020
Version 3.0.1 is the official release version of Reddcoin Core. It is available for download at Reddcoin Core's Github repository here: https://github.com/reddcoin-project/reddcoin/releases/tag/v3.0.1
This release features PoSV v2.supermajority activation and new staking ruleset (and minor misc fixes). v3.0.1 is still not yet MacOS Catalina compatible. We are still working and should have that fix issued very soon. Sincere apologies to our Mac-using ReddHeads.
It is particularly important that all users upgrade, as once PoSV v2 is enforced, version 4 blocks will be rejected from the network entirely.
Therefore v3.0.1 is a "strongly recommended" update for all users. Note: If you have already installed v3.0.0, this upgrade is not required. If you have not yet upgraded from v2.0.x or earlier, this is a REQUIRED upgrade. Please install the newest version v3.0.1 to avoid losing functionality during supermajority activation of PoSV v2.
Reddcoin Core version 3.0.1 is now available from: https://github.com/reddcoin-project/reddcoin/releases Release Notes are available here and replicated below in this announcement: https://github.com/reddcoin-project/reddcoin/blob/mastedoc/release-notes.md
This is a new major version release of Reddcoin.
Previously, the original and subsequent versions of Reddcoin were taken from a fork of the Litecoin code base.
With the release of Reddcoin V2.0.0, the code was based directly from a fork of Bitcoin. This allows for better source control and feature implementation from upstream changes into the future
With the release of Reddcoin V3.0.0, the PoSV stake reward has been improved to allow for a target 5% network growth, in process re-incentivizing individual network stakers and providing for integrated dev support.
Upgrading to this release is strongly recommended and required for continued operation. Once a supermajority of 90% is reached, old wallets will no longer accept the new v5 blocks.
Please report bugs using the issue tracker at github:
https://github.com/reddcoin-project/reddcoin/issues
How to Upgrade
If you are running an older version of Reddcoin, shut it down. Wait until it has completely shut down (which may take a few minutes for older versions). Run the installer (on Windows) or just copy over /Applications/Reddcoin-Qt (on Mac) or reddcoind/reddcoin-qt (on Linux).
Start wallet. All done!
Reddcoin v3.0.0 introduced an updated PoSV method to better distribute staking rewards and target a overall 5% network growth. Staking and relay policy enhancements 
To implement PoSV v2, Reddcoin Core's block templates are now for version 5 blocks only. When PoSV v2 consensus (Supermajority 9000/10000) is reached, only v5 blocks will be accepted by the network.This equates to approximately 90% of blocks being generated over 1 week period. Status at any time may be viewed in node debug.log

Have I lost my BSV?

HI guys
So, I've been hodling some BTC in a BitcoinQT wallet since before the BCH and BSV forks and I finally decided to claim them.
My BTC wallet had 4 private keys. I swept those private keys into my Electron Cash wallet, which I had restored from my Electrum wallet seed and had used previously to successfully split the BTC that was in the Electrum wallet.
So far, no problems. All the BCH showed up in Electron Cash. But then I tried the next step, which was use ElectrumSV to copy my Electron Cash wallet and use the built in splitting feature in ElectrumSV. That procedure worked perfectly when I split the BTC that was in my Electrum wallet, but this time, ElectrumSV only showed the BSV that was split from 1 out of the 4 private keys. The other 3 were missing.
The one that did show up, I had actually previously swept that key into my Coinomi BCH wallet before I rembered I had to split the BSV/BCH.
I'm hoping someone here can offer some guidance going forward. Were the coins double-spent whenI swept my BTC keys into Electron Cash? Any idea why ElectrumSV isn't acurately copying my Electron Cash wallet like it's supposed to? The transactions appear on the BCH blockchain, but not the the BSV blockchain. Should I just sweep those BCH keys into Coinomi at this point?
Hope this post wasn't too rambling and convoluted to follow! Any help would be greatly appreciated. Cheers!

Litecoin Support Phone Number +1(855)3008358 (Toll-Free Number)

Litecoin was released in October 2011 in the form of a client with an open source code on the Internet hosting GitHub by Charles Lee, a former Google employee. The crypto currency works according to the MIT/X11 license, which allows anybody to execute, modify and copy software as well as to distribute any modified copies. It was a fork of the Bitcoin-Qt client, differing primarily by having a decreased block generation time, increased maximum number of coins, different hashing algorithm, and a slightly modified GUI.
The Litecoin exchange rate gave a jump in November 2013: the capitalization of crypto currency exceeded 1 billion dollars.

Advantages and Disadvantages of Litecoin

Litecoin

Litecoin (LTC) is a decentralized cryptocurrency, a fork of Bitcoin intended by its designers to be more feasibly mined using consumer-grade hardware. Litecoin is a peer-to-peer crypto currency that was developed on the base of Bitcoin and has an open source code. Unlike Bitcoin, the Litecoin blockchain is able to process a greater number of transactions.
The creator of Litecoin – Charlie Lee, a former employee of Google – took the Bitcoin source code as a basis and created a crypto currency that needs 2.5 minutes to generate a block – this is 4 times faster than Bitcoin.The full emission of Litecoin makes out 84 million coins, which is also 4 times more than of Bitcoin. The start reward for a block made out 50 Litecoins, and now it is 25 Litecoins.

[TUTORIAL] -- How to SAFELY Claim New RNG Coins Using Your Private Keys

[TUTORIAL] -- How to SAFELY Claim New RNG Coins Using Your Private Keys

https://preview.redd.it/u4x1o4p37zc41.png?width=700&format=png&auto=webp&s=01d1ff52c0b7fc1c9ae5bb4f161979ad1f4bb559
I’m a longtime blockchain enthusiast and developer and one of my biggest gripes about this space is how quickly every new project is widely dismissed as a “scam” or “shitcoin” by so many people before it even gets off the ground. Sure, there is a lot of uncharted territory with pirates lurking to steal your bags left and right but with a small amount of personal education you can exist safely in the world of crypto I promise! With this article I aim to help lift your knowledge a little higher while helping keep your funds a little safer!

So What Is Happening?

On Tuesday February 18, 2020 a new coin named Ring (RNG) will be minted. This coin aims to bring two unique and fresh methods of proofing to the crypto game, quite literally: Agent-Based Hive Mining (borrowed from LCC) and Proof-of-Play Mining, where literal gameplay is used to hash and reward miners! To celebrate and help spread the word, the team is giving away claims of free RNG to all holders of the following coins:
  • Litecoin Cash (LCC)
  • Bitcoin (BTC)
  • Dash (DASH)
  • Dogecoin (DOGE)
It's being touted as the world's first crypto "4-way fork" but I'd really call it more of a "4-way claim" since its a brand new chain and not based on the code of any of the rewarded coins. It's simply a clever method of allowing a wider range of coin holders a chance to participate in the launch of these exciting new features!

How Will This Process Work?

On the 18th of February, a balance snapshot will be taken of the four chains listed above. Anyone holding a balance with any of these coins at the time of the snapshot will be forever eligible to claim their RNG at any time. Because the only way to prove ownership of a crypto address is to supply the private keys, and pretty much EVERYONE will tell you to guard those things with your life, below I will outline exactly what to do so there is absolutely 0% risk of losing a single satoshi! This method will apply to ANY claim rewards of any coin in the future as well. Always practice #SafeForking!

How Do I Safely Claim My RNG?

STEP 1 -- BEFORE THE SNAPSHOT -- VERIFY ACCESS TO YOUR PRIVATE KEYS
All core wallets will allow you to export a private key of any address in your wallet but many third party services like exchanges and hot wallets do not allow access to them. In these cases you will need to send your funds out of the third party service and into some kind of personal wallet where you can reach the private keys yourself. Then just wait for the snapshot to happen…
To make things easier on yourself, you can optionally collect your original coins into as few addresses as possible BEFORE the snapshot. Doing so reduces the number of keys you will need to empty and import later. It’s just less work!
\** SNAPSHOT HAPPENS HERE... ****
STEP 2 -- ATER THE SNAPSHOT -- EMPTY ALL ADDRESSES YOU WISH TO CLAIM
After the snapshot is confirmed, withdraw all coins OUT of each of your origin coin addresses into brand new addresses leaving the original ones quite empty. This way when you import later there is NO risk of losing anything! Also know that after you import these private keys you should never use them again for safety’s sake! It’s kind of the whole reason you’re even reading this article in the first place.
STEP 3 -- EXPORT PRIVATE KEYS FOR ALL ADDRESS YOU WISH TO CLAIM
This is the most difficult part, are you ready? Once each claim address is confirmed to be EMPTY, you must obtain each one’s private keys. This will entirely depend on the wallet you use (QT example below) but for all core wallets there is generally an option for exporting private keys somewhere in there. Collect them all!
How to Export QT Wallet Private Keys:⛔️ — DISABLE INTERNET FOR SAFETY — ⛔️- Open the QT wallet client- Click on HELP in the menu bar- Click on DEBUG WINDOW- Click on the CONSOLE tab- Click inside the input box at the bottom(if your wallet is locked…)- Type: walletpassphrase [Password] 600(this unlocks your wallet for 10 minutes)- Type: dumpprivkey [Address]- Copy the output hash, paste it into a list somewhere.(repeat as needed, clear your clipboard history after)- Type: walletlock (if applicable)⚡ — RE-ENABLE YOUR INTERNET —
STEP 4 -- IMPORT ALL PRIVATE KEYS INTO RNG CORE WALLET
\** PLEASE VERIFY THAT EVERY CLAIM ADDRESS IS EMPTY BEFORE CONTINUING... ****
The final step is to simply import each of these private keys into the new Ring Core Wallet to claim your free RNG rewards. The wallet handles this part automatically and you will see your new RNG balance right away. You can find this option under the File > Import Private Keys menu.
Importing a private key is the only way to prove ownership of a crypto address so this is unavoidable if you want to claim new coins from it. The steps above will allow you to prove ownership of your snapshotted address balance plus use its empty key to then claim your new coins thus keeping your original coins completely protected in the brand new address with a new private key (which you should now also keep VERY private!)
By emptying the address before you import it’s private key you eliminate the risk of theft entirely. One cannot take from an already empty jar. It should also be noted to NEVER use the imported address again as an added safety precaution*!*

How Much RNG Will I Receive?

Litecoin Cash holders will receive the highest claim ratio (5000 LCC = 1 RNG) as the LCC team are the ones responsible for creating Ring and wanted to extend a heart-felt thank you to the LCC community for their years of support. All other coins will be based on a 1:1 ratio with the value of Bitcoin at the time of the fork. This of course means 1 BTC = 1 RNG. For DASH and DOGE, however, their BTC market prices will determine their reward ratios. (For example if DASH is trading at 0.015 BTC each, then each DASH coin will net you a reward of 0.015 RNG to match.) Of course you don't need whole coins to claim, partial decimals work just fine!

What Value Will RNG Have?

That, my friends, is entirely up to the markets. No one in the history of crypto has had a perfect track record of price predictions so I'm not even going to try here. I will say, though, having gotten to play with their Testnet a bit so far that I am very impressed with the new Proof-of-Play method and how they have initially implemented it. It bodes very good things for the future of their project and this coin so I personally would expect its value to hold and most likely rise steadily as more people become aware of this groundbreaking new tech and it's potential to expand outward!

Is Litecoin Cash Still Going To Exist?

Absolutely! At least, from what I can gather. LCC has it's own purposes and will continue to be developed on. Ring is not meant to be a replacement or upgrade of any kind to Litecoin Cash. It is an entirely different proofing algorithm and a different mission statement altogether. It's more so meant to help expose the amazing new technologies developed on the LCC blockchain to a wider audience beyond simply its own fan base. If anything it'll act a sister chain that can help expose more folks to LCC in the future!

Disclaimer

While I am a moderator for the Litecoin Cash Discord server, I am writing this from an independent point of view as an educated crypto enthusiast with a passion for helping others navigate these waters. Having been an initial forker and third party developer on top of LCC myself, I feel I have some valuable insight into the direction the team is taking and I wanted to offer some sound advice for the upcoming Ring fork before the FUD gets caked on too thick.
I know a lot of people get scared easily in crypto because of the rampant scamming that goes on but I've watched this team work their asses off for two years to get out from under the stain of Charlie Lee's very biased, uneducated "its a scam" tweet which was endlessly parroted throughout the Litecoin community with nothing but blind party loyalty and no due diligence. The LCC folks are kind, wonderful hard-working people with big hearts and ambition and they have actually developed a unique proofing methodology that is likely going to impress a lot of people!
So before you go jumping on the "it's just another shitcoin" bandwagon please stop and take a real hard look at both Litecoin Cash (LCC) and Ring (RNG): two viable projects with something to bring to the table! If nothing else, hey, just claim your new coins and dump them off for some free money. You literally cannot lose if you PRACTICE SAFE FORKING!!!
Good luck, cryptonauts!

After asking here about setting up bitcoin payments for my new online store, I have some feedback as a new user (warning - long post).

I wanted to check back in firstly to thank all of the people who gave me help and advice. I run a small business and my grandson recently convinced me to open an online store. After some brisk trade on the website, he mentioned Bitcoin.
I did some preliminary reading, and made a reddit account to ask for some advice.
The first thing that I discovered is that not only are most of the people that I interacted with very friendly, they were giving me HONEST advice. I received private messages containing a surprising amount of detail regarding other peoples personal experience accepting bitcoin and how to decide if it was right for me. Not just mindlessly pushing it.
After a day of chatting here, and a long conversation with my grandson I decided to take the plunge. Here starts my feedback about Bitcoin, rather than the excellent community here.
Setting up a 'core' wallet on my desktop machine was a bit of a pain. I didn't spot anywhere on the download page warning of the insane amount of time it takes to sync. Neither did I spot any warning about just how big the 'blockchain' is. It DOES say that it takes up 'a lot of space and memory' but that's hardly a technical description. I later installed Mycelium on my phone, and THAT was a perfect example of how software should work. Setup was quick and easy and the interface is really user friendly. I know it sacrifices some security, but that is a worthwhile trade off in my opinion for people new to bitcoin.
I originally tried to set up my store using Bitpay as a merchant per the advice here, but apparently it was throwing up errors after my grandson installed it on my site. I allowed him to try Bitcoinpay instead, as he claimed it would work 'out of the box' which is important for myself as I don't have the expertise to solve problems.
While I saw no reviews or recommendations for Bitcoinpay, I've tested it using some bitcoin kindly tipped to me in my last post. The money from my test transaction is now sitting in my bank account as £. The fee at bitcoinpay is 0.8% and I lost about another 1.5% in currency conversion (they pay out in euros, so it's my banks lousy conversion rate to blame, not bitcoin). It's still significantly cheaper than Paypal, and will allow me to offer better deals for bitcoin customers. Everyone wins.
So in closing, the community is excellent and supportive, the full wallet is a pain, Mycelium kicks ass and setting up a store that accepts bitcoin was trivially easy once I had access to all of the right resources. I now have an online presence which is capable of accepting Bitcoin, and at a greatly reduced risk to myself in comparison to Paypal.
Even if I never get a single customer paying with bitcoin, it was still worth setting it up as I've learned a LOT during the process.
Thanks everyone.

Bitcoin-Qt has been running for over a week and still hasn't synced

I downloaded and started the Bitcoin-Qt wallet over a week ago, and it's still at blocks from 29 weeks ago. The wiki says that it takes about a day... Is this normal?
Thanks.

[TUTORIAL] -- How to SAFELY Claim New RNG Coins Using Your LCC Private Keys

[TUTORIAL] -- How to SAFELY Claim New RNG Coins Using Your LCC Private Keys

https://preview.redd.it/9csw52aw30d41.png?width=700&format=png&auto=webp&s=53ceb329c9772d7f0abbcc56b44ba405e34dd8a8
I’m a longtime blockchain enthusiast and developer and one of my biggest gripes about this space is how quickly every new project is widely dismissed as a “scam” or “shitcoin” by so many people before it even gets off the ground. Sure, there is a lot of uncharted territory with pirates lurking to steal your bags left and right but with a small amount of personal education you can exist safely in the world of crypto I promise! With this article I aim to help lift your knowledge a little higher while helping keep your funds a little safer!

So What Is Happening?

On Tuesday February 18, 2020 a new coin named Ring (RNG) will be minted. This coin aims to bring two unique and fresh methods of proofing to the crypto game, quite literally: Agent-Based Hive Mining (borrowed from LCC) and Proof-of-Play Mining, where literal gameplay is used to hash and reward miners! To celebrate and help spread the word, the team is giving away claims of free RNG to all holders of the following coins:
  • Litecoin Cash (LCC)
  • Bitcoin (BTC)
  • Dash (DASH)
  • Dogecoin (DOGE)
It's being touted as the world's first crypto "4-way fork" but I'd really call it more of a "4-way claim" since its a brand new chain and not based on the code of any of the rewarded coins. It's simply a clever method of allowing a wider range of coin holders a chance to participate in the launch of these exciting new features!

How Will This Process Work?

On the 18th of February, a balance snapshot will be taken of the four chains listed above. Anyone holding a balance with any of these coins at the time of the snapshot will be forever eligible to claim their RNG at any time. Because the only way to prove ownership of a crypto address is to supply the private keys, and pretty much EVERYONE will tell you to guard those things with your life, below I will outline exactly what to do so there is absolutely 0% risk of losing a single satoshi!

- Copy the output hash, paste it into a list somewhere.
(repeat as needed, clear your clipboard history after)
- Type: walletlock (if applicable)

The Xtrabytes scam needs to be shut down and the people need to face criminal charges

I came across something the other day that caught my attention. I decided to finally read their first ever post: https://bitcointalk.org/index.php?topic=1793468.0 on bitcointalk.org. Until now, I had only looked at the first page or two. Some interesting bits from the first few pages:
1 year and 10 months later, we have no actual proof that he is a real person (at least not who he claims to be). The proof he is a real developer is extremely limited. We have zero proof that he is capable of developing what he claims he has. XBY has been anything but transparent. All 3 of these claims appear to be to entice people into buying into the Xtrabytes scam.
This should have NEVER been done, though it’s not surprising that C-Cex would do something so incredibly stupid. They should have delisted XBY, which would have forced Borzalom to start from scratch and apply for listing on the exchange with a new coin he created. Had they done this, it’s likely this whole scam would have never happened, as he has shown no development skills whatsoever and likely could not have made anything from scratch.
All that is IF it even is the true story. I don’t believe it to be. I believe Borz was in on Bitmox, which is why he had the source code. No chat with C-Cex ever happened, which is why the messages between Borz and C-cex support that are included in the post are plaintext when other bits of info are snippets and screenshots. He didn’t provide a snippet picture because the conversation never happened. There is further proof that it didn’t happen if you look at the language used by both Borz and the support person - they use the same language, which is notable by the overuse of adverbs, such as ‘very’ and ‘perfectly’. Borz typed these messages himself.
No additional code has ever been shown. The new algorithm he claims to have created, Proof of Signature, has never been seen or proven. Given the details, It’s likely that he never did any additional coding after the hard fork and the code is nearly the exact same as when he closed it.
If you care to continue reading, they get called out be being a scam within the first few pages by multiple users. The delays and stalls start almost immediately. Borz has never shown any additional code, as it doesn’t exist.
Some additional links:
This has all been discussed many times and this Bitcoin Talk post does a great job putting all the pieces together.
Here is a post that contains a message from CCR says the patent is all a delay tactic.
Within these posts, there are messages from CCR saying that he’s been selling his XBY. https://imgur.com/a/QtMXi0q
You can find Borzalom‘ real identity, as well as old posts from 3 coins, like Identity, that he copied from someone else and then shut down abruptly out of nowhere. He claims he’s from Hungary, but he had a business registered in Florida. Everything points to him living in Florida. He’s not deaf and he’s not a world class coding god.
It kind of becomes a rabbit hole of sorts, but if you care to read, it’s quite interesting and IMO proves without a doubt XtraBytes is 100% a scam.
Nothing has changed. Borzalom and CCR are criminals. They deserve to be in prison. There is enough proof of XBY being a fraud and conversely no proof their technology exists whatsoever.
XtraBytes needs to be shut down and the people responsible need to face criminal charges, that includes all their mods and team members that KNOW this is a scam, but keep it up because they’re being paid.

Did I fuck up?

I was trying to fix a problem with bitcoin-qt, it wasn't recognizing the block chain. Apparently the solution to this was to delete everything except wallet.dat and run bitcoin-qt again so it would re-download the blockchain. I know it's stupid, and I was kind of in the mindset "I can't really do any damage cause it will just be moved to the recycle bin" but I didn't back up the wallet.dat file. When I ran bitcoin-qt the it looks like it overwrote the wallet file as it now saws my balance is 0 BTC. Looking back on it it seems obvious that I was meant to move the wallet file out and then use it to replace the new one it made.
Is there any way to get it back, or is it gone forever, it was only about $100 worth so I'm not that upset about losing it.
Edit: There were no previous versions to restore to, I'm downloading recuva now.
Edit2: Recuva didn't find anything with .dat or .bak in ...AppData/Roaming/Bitcoin. I'm running a deep scan now.
Edit3: I'm synced with the block-chain, so that's not the reason its not showing a balance.
Final Edit: It has a happy ending! I remembered I had cloned my hard-drive a few months ago and was able to recover the wallet.dat file off that!
Thanks for all the help.

Blockchain and BitCoin QT sharing same wallet...

So I started out with a blockchain.info wallet, which I got on very well with: using easily, web access, client side encryption etc...
I then ventured into BitCoin QT, which I downloaded and synced with the swarm, but now I have two wallets...
What I am wondering, is am I able to export my blockchain.info wallet.dat, into BitCoin-QT so that I am running a single wallet in bit instances?? (Also would prefer not to switch blockchain to the wallet setup in BitCoin-QT which I know you can do (importing into blockchain.info) - basically I would like to export my blockchain.info wallet...
Also, might I run into any issues if I manage to do the above?
I am running BitCoin-QT on OSX if that is of any significance...
Thanks!

Bitcoin-qt crashes when starting up

I've been trying to run Bitcoin-qt today without success. I've tried the obvious things, like restarting my computer, but that's about the limit of what I can think of to try.
Does anyone have suggestions? I'm on Mac, running OS X 10.7 Lion. And if it can't be fixed, can anyone recommend an alternative client?

How I lost all of my hard earned money.

So, like many people I started getting involved in Bitcoin fairly recently ~Fall 2011. When I started I vowed to only spend what I earned. So I overclocked my home server's and my laptop's GPU to do some mining. I earned a lot of bitcoins fairly quickly with 2 machines running and the relatively low difficulty of hashing at the time. Whenever I had enough bitcoins I would buy things from btcdeals (got some pretty cool stuff from them) and bitcoincodes (get WoW for leaving my computer on when not in use? hell yea). I got excited with the rises and pissed at the falls but I still enjoyed it. I used to have ~2BTC but I foolishly reformatted my computer holding my bitcoins without making a backup. It was only after a fresh OS install did I realize my mistake. I managed to recover a whopping .08BTC from the hard drive... the rest of my private keys were just gone.
I now use blockchain.info online wallet and have it backed up to my dropbox... too bad hindsight is 20/20.
Back to the mine with my GPUs.

(Updated) [Staking] Reddcoin Core client GUI wallet on a Raspberry Pi Model 3B

Intro

This thread is an update to my first Reddcoin staking tutorial that was written 7 months ago.
 
The reason for the update
My Reddcoin Core software crashed and became unusable. My Raspberry Pi 3B would lag and freeze, I couldn't stake anymore.
 
Instead of just redoing everything the same way, I wanted to see if I could improve on 3 points:
 
The updates
 
If you would like to tip me
Writing a tutorial like this takes time and effort; tips are appreciated. My Reddcoin address: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.
     

Overview

 

Steps

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
     

Video

https://www.youtube.com/watch?v=Snr5e8bzftI
This video shows how long it takes to start Reddcoin Core.   TL;DR:
     

Extra

Backup
Backup your wallet to prevent losing the RDDs in your wallet! There are two methods to backup, do both. Make new backups if you create a new receiving address!
 
 
   
Boot with only 1 USB drive plugged in:
Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly.   If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
   
Connection issues If you have issues syncing the blockchain because you have 0 network connections, please follow the instructions in this thread.
   
Start Reddcoin Core easier
Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
   
Minimization options
Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
   
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
 
   
Chromium as browser: The updates break Firefox, the browser crashes when you try to run it. Install another browser, Chromium, to solve this issue.
   
Updates / Upgrades
If Software Updater shows up and tells you that there is updated software available, do not install the updates using Software Updater. Use LXTerminal to update Lubuntu.

How to Download and Verify the Armory Bitcoin Wallet Blockchain Wallet  How To Create Blockchain Bitcoin ... How to hack a bitcoin wallet (blockchain) - YouTube How to Sync your Bitconnect QT wallet NEW updated Be Careful while Copy/Pasting Bitcoin Wallet Address - YouTube

1. Install Bitcoin-Qt Since version 0.9, Bitcoin-Qt was renamed to Bitcoin Core t o reduce confusion between Bitcoin-the-network and Bitcoin-the-software. Bitcoin Core is a full Bitcoin client. It is a thick client, meaning it requires the full blockchain (explained below) on local disk to operate and expose blockchain back to the network to help relay and verify transactions. After installing the bitcoin client (Qt) a friend got interested as well. He doesn't have as fast an internet connection, though, so I thought of burning some DVDs with the blockchains for him to have. I saw this question on how to transfer blockchain from PC to Mac and the solution was to copy the whole "Bitcoin" folder. However, that folder ... Copy the Bitcoin Data Directory . Having found the default data directory, we can now copy it. Be sure that Bitcoin Core has been shut down and is no longer running. The software occasionally takes a minute or two to completely exit. Begin by renaming the Bitcoin Core data directory. Use the name bitcoin-backup. Don’t move the renamed folder. Copy your backed-up wallet.dat into your bitcoin data directory. If you are copying in a backed-up wallet.dat that was last used on a Bitcoin version prior to 0.3.21 into an existing profile, delete files blk*.dat to make the client re-download the block chain. The binary files for Windows, Mac and Ubuntu differs. But Yes, the wallet backup file, database file and other core files such as: wallet.dat, wallet.keys, lmdb (data.mdb, lock.mdb), blk*.dat, .ldb files are compatible across platforms. So you can basically move your wallet to Raspberry Pi or another computer or different operating system without having to download the entire blockchain again.
