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.

PSA: Enable Tor as a simple way to make your node reachable.

Become one of the 10% of node operators that receive incoming connections.
Installing bitcoin core is easy, and with pruning it really isn't the space sink it is characterized as. Even a modest computer can complete the initial block download (IBD) and become a full node. But what some users (90%) find a bit more challenging, is how to become a listening node. Listening nodes are an important part of the network, and are simple enough to enable. I can think of 4 ways to do it:
  1. Operate on an OS and Network that support uPnP, allowing bitcoin to open the ports for you.
  2. Subscribe to a VPN that allows you to open ports through their service.
  3. Manually configure your OS and network to forward port 8333 and 18333.
  4. Run Tor and direct bitcoin to listen through it.
I'll discuss #4. Obviously #1 or #2 are easier, but require a VPN subscription or uPnP enabled HW. And if you live in a dorm or don't control the network, Tor may be the only free option available.
As a bit of background, bitcoin supports three networks that your node can listen on:
Obviously, the more you enable, the better, but here are the basic steps for Tor in broad strokes. If you have any questions post them here and I'll see if we can't help you out:
  1. Download, verify1 and install Gpg4win
  2. Download, verify2, install, and launch Tor Browser
  3. Download, verify3, install, and launch Bitcoin Core
  4. Launch and Admin command console in the directory containing tor.exe
  5. Install the Tor service: tor.exe --service install
  6. CD to service dir: cd %windir%\ServiceProfiles\LocalService\AppData\Roaming\tor
  7. Create and edit a file called torrc with the contents suggested below
  8. Restart tor: tor.exe --service stop && tor.exe --service start
  9. Record the hostname: type .\HiddenService\hostname as
  10. Add the bitcoin.conf options suggested below
  11. Restart the bitcoin-qt program
  12. (Optional) Activate the bitnodes crawler at https://bitnodes.io/nodes/-8333/
It may take a while for your node to show up on bitnodes. I've found the check button sometimes has trouble with onions. Of course you don't need to do it, but it can provide a simple way to check status once your on the list.

torrc file: (replace c:\windows with the proper path as needed)

```

Change to C:\Windows\ServiceProfiles\LocalService\AppData\Roaming

Log notice file \tor\service.log

Bridges may be needed if the Gov't shuts down Tor exit nodes. Get Bridges by

emailing [email protected] from Gmail (only) and uncomment as follows:

Bridge obfs4 : cert= iat-mode=

HiddenServiceDir \tor\HiddenService HiddenServiceVersion 2 HiddenServicePort 8333 127.0.0.1:8333 HiddenServicePort 18333 127.0.0.1:18333 ```

bitcoin.conf file: (entries to be ADDED)

```

Change to what you recorded earlier

onion=127.0.0.1:9050 listen=1 externalip= discover=1 ```

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

  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

  1. Select the Receive tab in Bitcoin Core (testnet)
  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

Bitcoin Tor

Subject: PSA: Make your node reachable by using Tor
There is usually a post every few months with someone asking for tips on how to make their node reachable. It's always a hard question to answer since its impossible to know what type of routers and firewalls they are going to have to punch through. This is especially difficult in college dorms. One cheap (and easy) way around it is to to just jump through a few extra steps to make your bitcoin node a bitcoin onion node. Tor is great about traversing routers and firewalls like a hot knife through butter.
  1. Download, verify1, install and initialize Gpg4win
  2. Download, verify2, install, and launch Tor Browser
  3. Download, verify3, install, and launch Bitcoin Core
  4. Launch an Admin command console in the directory with tor.exe
  5. Install the Tor service: tor.exe --service install
  6. CD to service dir: cd %windir%\ServiceProfiles\LocalService\AppData\Roaming\tor
  7. Create and edit a file called torrc with the contents suggested below
  8. Restart tor: tor --service stop && tor --service start
  9. Record your onion hostname: type .\HiddenService\hostname as
  10. Add the bitcoin.conf options suggested below
  11. Restart the bitcoin-qt program
  12. Verify node connectivity at https://bitnodes.io/nodes/-8333/

torrc file: (replace c:\windows with the proper path as needed)

```

Change to C:\Windows\ServiceProfiles\LocalService\AppData\Roaming

Log notice file \tor\service.log HiddenServiceDir \tor\HiddenService HiddenServiceVersion 2 HiddenServicePort 8333 127.0.0.1:8333 HiddenServicePort 18333 127.0.0.1:18333 ```

Forgot to upgrade your node? Here's how to get back onto the upgraded BCH network:

These instructions are for those who left old versions (0.20.12 or older) of Bitcoin ABC running through the May 15th, 2020 upgrade. Follow these instructions to get back on the main network.
If you are using bitcoin-qt, follow these steps:
  1. Stop your running node
  2. Delete the list of nodes you have banned: rm ~/.bitcoin/banlist.dat
  3. Download version 0.21.x from https://download.bitcoinabc.org/latest/
  4. Start up the new version (./bin/bitcoin-qt)
  5. Open Help -> Debug window
  6. In the console type reconsiderblock 00000000000000000033dfef1fc2d6a5d5520b078c55193a9bf498c5b27530f7
  7. Wait until your node is on the correct chain. This could take some time if your old node was running for a while, and other nodes banned you on the network. You can check that you are on the correct chain by typing getblockchaininfo and verifying the information with a public block explorer such as https://explorer.bitcoin.com/bch, https://blockchair.com/bitcoin-cash, or https://cash.coin.dance/.
If you are running bitcoind, follow these steps:
  1. Stop your running node
  2. Delete the list of nodes you have banned: rm ~/.bitcoin/banlist.dat
  3. Download version 0.21.x from https://download.bitcoinabc.org/latest/
  4. Start up the new version (./bin/bitcoind)
  5. Use bitcoin-cli to type: ./bin/bitcoin-cli reconsiderblock 00000000000000000033dfef1fc2d6a5d5520b078c55193a9bf498c5b27530f7
  6. Wait until your node is on the correct chain. This could take some time if your old node was running for a while, and other nodes banned you on the network. You can check that you are on the correct chain by typing ./bin/bitcoin-cli getblockchaininfo and verifying the information with a public block explorer such as https://explorer.bitcoin.com/bch, https://blockchair.com/bitcoin-cash, or https://cash.coin.dance/.

How I synced on a 2013 ultrabook in a few days

Note: I don't know exactly how long it took because I didn't do it in one go. I guess it was like 4,5 days doing it only at night. At some points(2015Q3, 2018Q2) it slows down and ETA goes up to 16 weeks or something.
The main bottleneck is IO. My 2013 mobile i3 has enough processing power to sync, I only used 3 threads and most of the time only one was close to 100%. The two directories that need to be written and read from intensively are chainstate and blocks/index. I pruned to 2GB and chainstate didn't go much over 3GB during the entire process. blocks/index is like 100MB.
The best solution is to move chainstate and blocks/index to a ramdisk. If you don't have enough ram the linux kernel has a thing called zram. Zram creates a compressed swap(cache) file in ram, this effectively increases your ram size at the cost of a bit of processing power and access speed(of the compressed part). On my machine I can net a bit more than 1GB of extra ram. That's right, with linux you can download more ram! The second best solution is to leave chainstate and block/index on a sdd. From what I've tested it should take up between 5 whole days and 2 weeks.
With regards to config, I didn't see much benefit in increasing the db cache over the default 450MB in bitcoin-qt. If I recall correctly, smaller prune sizes make chainstate larger.
After the initial sync keeping up to date is very easy on resources. You can catch up a week in a few minutes. At the moment bitcoind is using 400MB but I'm still working on bringing that number down.
Remember: If you want safety or if you want to help the network you need o run a full node. A full node is a node that verifies all transactions. A pruned node is a full node.
Edit: bitocoind really likes to hover around 400MB, sometimes it gets higher than that, some times it get's lower. A lot of that is data, not code, so if you start running out of ram your OS should drop those pages and get down to 250~300MiB. If you really want the memory to be this low all the time, on linux, you can either: Use cgroups to set the swappiness of the process to 99 so all data gets swapped but not code does; Use systemd and set MemoryLimit=300MiB(for example) so almost all data gets swapped but no code. I don't think any of those options are worth the small setup hassle.

WALLETS, SETUP GUIDES & SNAPSHOTS
Just a reminder for the community and also for any new members, we have added a Wallet Setup Guides page, which takes any first time user of Mousecoin step-by-step through the process of installing their Mousecoin wallet and getting it online. The guide uses the latest blockchain snapshot found on the Wallet Downloads Page in the example explanation meaning that all new members of the Mousecoin community will be able to get their wallets online faster as the sync time should be minimal. We will be updating the blockchain snapshot at least once every month to ensure that people have access to the most up to date blockchain info. The latest blockchain snapshot was performed on the 1st June 2020.
The wallet version is currenty V1.0.0.0, with future releases of the Mousecoin wallet coming soon

POS & STAKING
In the last month we asked the community if they would be interested in being a part of a Community Staking Pool. After investigations into this finding security flaws in most platforms, as well as the lack of interest from members of the community we have decided to not go ahead with the Community Staking Pool. While we understand that there are members of the Mousecoin Community that are unable to stake themselves for whatever reason, and that there are a number of staking platforms that offer pool staking for MIC3 to help these people stake, we will not officially be supporting any staking platforms. We ask all Community members using these or thinking about using these to keep in mind that any MIC3 hosted on these platforms is not in their wallets, and therefore not controlled by them. Do proper investigations into any platform that you use for this as there is always the possibility of loss. We encourage all members of the Mousecoin Community to stake from their own wallet (where possible) as this helps us to secure the network. If you need help setting up your wallet, go to our Wallet Setup Guides page for step-by-step guides on setting up your Mousecoin wallet.
MOUSECOIN FAUCETS
We have updated the Mousecoin (MIC3) Faucets Page:
To make things clearer and we will be adding more faucets soon!
EXCHANGES
Last month we saw the edition of the USDT/MIC3 pair to nanu exchange. In our efforts to increase exposure of Mousecoin, we are still attempting to list on both ATAIX and Unnamed.Exhchange.
ATAIX We have risen to 18th position in the voting list on ATAIX, but we still need your votes. Remember you can vote every 24 hours for this listing, and you can share in 125,000,000 MIC3
📷
Unnamed.Exhchange The exchange listing for Unnamed.Exhchange is 0.05 BTC. For anyone unfamiliar with the exchange there are two ways that you can donate to the listing:
1. If you are already a member of, or wish to be a member of Unnamed.Exhchange (and why wouldn’t you), you can put funds towards our listing by tipping us through the trollbox (Mousecoins). If you wish to be a member of Unnamed.Exhchange, you can register here: https://www.unnamed.exchange/Login/Register
2. You can also donate to the listing fee through the following addresses: BTC – bc1qmaqzhfqcw0urva0rtgfz5qvq4rw7kdnp6j7754 LTC – ltc1qc775eeftdde2jrevnyukrd2w9853jy5gmtv6rn DOGE – DEnBpriaFnKiNeBv6Q7MVxMg5hLv5urQFg UTIP – AUTyu2JhGAaCkM3KAmeBopto2bNBchNJfE
If you would like to donate in another crypto available on Unnamed.Exhchange, we have opened up the chat on the Discord channel HERE to assist with this. Please request the address and we will provide it for you. ANY AND ALL DONATIONS ARE WELCOME!! This is a good exchange and getting a listing her should help lift the profile of MIC3.
We will be reporting balances to the discord channel https://discord.gg/cYuA8FA
COMMUNITY FUND
📷
In the last month the Community Fund has undergone a huge amount of change. We have completely moved all of our remaining balances away from 4Stake, with the MIC3 going to the Community Fund MIC3 account and the remaining crypto’s towards out listing on Unnamed.Exhchange. The Community Fund page on the website has also been updated to reflect all of the changes. It is an exciting time for the Community Fund as we have now reached a balance that will sustain itself. This is why we have introduced the Community Member payment, and are able to sustain the faucets we have on https://erex.io/freecoin/ and in the Phoneum Games. There is still more to come!

#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

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

Windows
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
OSX
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet.
If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

UPDATED – Groestlcoin Sentinel 3.5.06 (Android)

Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets).
Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet.
Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.

Bitcoin Full Node - Raspberry Pi

On all the tutorials I see for running bitcoin on a raspberry pi, they all git clone bitcoin from github and build bitcoind from source. Is this necessary?

Can I not just download / verify signatures of bitcoind / bitcoin-qt from bitcoin.org and run the executables?
submitted by ribeyezz to BitcoinBeginners [link] [comments]

How will the (literally) growing problem of an enormous blockchain be addressed in the future?

To my knowledge, we need a complete history of the blockchain to be able to assure ourselves that transactions and balances are accurate.
Could 'someone' we trust cryptographically sign and verify a block in the middle of the chain? For instance, Mt. Gox could take block 210,000 and a snapshot of all known balances, and sign it with the private key and certificate they use for the website.
How do bitcoin wallets run on cell phones without a complete copy of the multi-gigabyte blackchain?
I quess my beef is that when I recently installed bitcoin-qt on a new computer, it took me like 2 days to download the history to be able to use my new wallet freely... Is this making any sense?

(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:

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.

[ELI5] How to send coins using Coinb.in

How to send coins from ANY wallet using https://coinb.in/#settings

Why?

Because cold wallets, such as those stored offline in a text file as I keep recommending in my standard advice below:
All you need is a text file to put your wallets in, like this example from https://walletgenerator.net/?currency=Dogecoin
1,"D7WBUpdgLRtG6WyPsqjhaKiJR65X8ZGnkZ","6KieLMW1poAzNVnmLuQZqA262gxEQ51eLGdDK8e2GL2B4LHCKKb" 2,"DM8LT16d49zHr8ByXbUwZb9UBXDGMaZRdc","6Ktgxdv6vN9v2bDHwcJBBb3oMRAgXJumESzBnxaXUSGFZoq6pWQ" 3,"D5UCa51AfxjtVHQ46oYXe2YfkctTeLXPhx","6L2WSPWadRYCwt2L1CxH6zC7PoTYY3KyjxdiUoCqi5eyq6hQKvj"
Use https://coinb.in/#settings to move coins. Download both sites and run them offline. Use https://bitinfocharts.com/dogecoin/ to check balances and transactions. See http://www.mocacinno.com/blog/create-sign-broadcast-transactions-using-coinb/ for coinb.in tutorial. And read the ELI5s (and my history) for more info.
Are without doubt THE SAFEST way to store your coins. Plus, they consume no resources. No bandwidth, no network stress for every node we have, no storage of 20Gb+ blockchains, no weeks of waiting for things to sync, no tearing your hair out and posting desperate pleas for help, and most importantly, no coins irretrievably lost because you or your client screwed up.

What?

Wallets, ALL WALLETS are nothing but numbers. Very large numbers, but fundamentally no different from “7”, “42”, “911” or a phone number. They cannot be created nor destroyed, and you either know them or you don’t. Anyone who knows a key can use it to spend any coins it controls. Anyone who doesn’t know it, can’t. Don’t be the guy who doesn’t know his own keys. Keep them safe. Make copies. Keep those safe. Don’t let your friends, kid brother or random burglar find them, but don’t lose them either.
The only other thing you need for a fully functional wallet is a way to spend coins. Coinb.in is such a way. There are others, such as DogeCoinMultiSig.org which tomcarbon built.
Oh, and you can and should download it and run it locally.

Where?

The default entry point for coinb.in is https://coinb.in/#settings because this settings page is very well hidden. Its in the tiny gear wheel on the Broadcast page.
Looking across the top of the page, you can see
  • + New
  • Verify
  • Sign
  • Broadcast
  • Wallet
  • About
We’re only going to use three of these. New, Sign, Broadcast.
Now, keep in mind that coinb.in is an old Bitcoin tool which tomcarbon added Dogecoin to. Sometimes it thinks its dealing with Bitcoin still, so if you see anything odd, go and make sure you’ve selected Dogecoin in the Settings page.

When?

This tool should be the only place you spend coins. Sure, some clients may look more convenient, but they all suffer from a very big coin-losing flaw. Whenever you split a UTXO, they create a new wallet to send the change to. And they DON’T TELL YOU! This means unless you back up after every transaction, you run a high risk of finding all your coins have ‘disappeared’ from your wallet, and you don’t recognise where they went.
So if you use a client for the convenience as well as a text list of your wallets, you won’t know to add a new wallet to your masterfile. Its best to ditch the clients entirely.

How?

Now we come to the nitty-gritty. Lets use those three wallets above and assume that #1 is the source, #2 the destination and #3 the change wallet. Note that these won’t actually work, as none of them have ever been used, but they will do as examples.
New Transaction
Located at the bottom of the New menu, this will give you a page to enter your wallets and amounts.
In the top field, you enter your source address or Key. If you use the key, it will calculate the address when you click the Load button, which should match what you expected. Note that Load only brings in the first 100 UTXOs. This is so that you can retrieve coins from high-volume wallets which would kill any client. Coinb.in is in fact the ONLY WAY to do this, as even QT falls over around 600 UTXOs.
You will see the total balance that was loaded in the Transaction Fee field. And also in the Inputs tab, where you can go to adjust which UTXOs to spend.
Now you need to add the wallet(s) and amounts to send to them. Lets suppose the source contained a single UTXO for 1,000 Doge. You want to send 500 of them. So you would enter the #2 address in the Address field, and 500 in the Amount field. The Fee now changes to 500, which is not what you want.
So you click the + button to bring up a new line, enter the change address and the other 500, making the fee zero.
And you’re done. Check that the Fee is indeed zero. Check that the amounts shown in the Outputs and Inputs tabs match exactly.

THIS IS CRITICAL!

There is a bug which will send all the coins to the miners if the Outputs exceed the Inputs. I would have expected the Fee to show as negative in such a situation, but it doesn’t. BE WARNED!
Once everything looks right, hit the Submit button.
This will give you a block of hex code. Copy it.
Sign
Go to the Sign tab and paste it. Add your private key for the source wallet and click Submit. Note this can be done offline for safety.
This will give you another block of hex, the SIGNED transaction.
Broadcast
Copy this and paste it in the Broadcast tab and click Submit.
That’s it. Your coins are on their way. Make a cuppa and settle in while they arrive in a minute or three.
Note: All fields retain their values unless you refresh the page! This can be a boon when doing multiple transactions, such as when emptying a huge wallet. But it can also be a trap for the unsuspecting. Refresh or close the window when you’re done.

Who?

Who should use this?
Absolutely EVERYONE!
Even if you’re wedded to your client in some satanic blood-contract, you should still know how this works, because sooner or later you’re going to have a problem you can’t fix without it.
Definitely download the site and store it on every device you have. On every USB backup of your wallets. On your phone (well, except iOS which doesn’t do local HTML), etc, etc, etc.
Oh, and if you’re a programmer SmartyShibe, do consider improving the code over on GitHub.

Why there isn't a zip file of the blockchain for the first 3 years for quick download?

So if the blockchain is a pain in the ass to download for the first time, why can not be in a zipfile for the first X years, and only the last few weeks or months need to be downloaded/upgraded? Is that really that hard to implement?
If bitcoin will really take off, there will be more and more transactions, so the blockchain is getting bigger and longer faster, so it would make sense that past months would be in an easily handable zip file. Even if this zipfile updated just bimonthly, that means that new users need to download only the last 2 months transactions, the previous years should be a quick download....
