How To Install Bitcoin Core on Ubuntu – Linux Hint

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.

[ANN][ANDROID MINING][AIRDROP] NewEnglandcoin: Scrypt RandomSpike

New England
New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/
NewEnglandcoin
Symbol: NENG
NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones.
Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt.
1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377
NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number
Bitcoin Fork - Suitable for Home Hobbyists
NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs.
The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

CPU Minable Coin Because of dynamic difficulty algorithm on top of scrypt, NewEnglandcoin is CPU Minable. Users can easily set up full node for mining at Home PC or Mac using our dedicated cheetah software.
Research on the first forked 50 blocks on v1.2.0 core confirmed that ASIC/GPU miners mined 66% of 50 blocks, CPU miners mined the remaining 34%.
NENG v1.4.0 release enabled CPU mining inside android phones.

Decentralization and Community Driven NewEnglandcoin is a decentralized coin just like bitcoin. There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG.
We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

ASIC/GPU Mining Pools Warning to Big ASIC Miners Due to DynDiff Algo on top of Scrypt, solo mining is recommended for ASIC/GPU miners. Further more, even for mining pools, small mining pool will generate better performance than big NENG mining pool because of new algo v1.2.x post hard fork.
The set up configuration of NENG for scrypt pool mining is same as a typical normal scrypt coin. In other word, DynDiff on Scrypt algo is backward compatible with Scrypt algo. Because ASIC/GPU miners rely on CPU miners for smooth blockchain movement, checkout bottom of "Latest News" section for A WARNING to All ASIC miners before you decide to dump big ASIC hash rate into NENG mining.
(1) Original DynDiff Warning: https://bitcointalk.org/index.php?topic=5027091.msg48324708#msg48324708 (2) New Warning on RandomSpike Spike difficulty (244k) introduced in RandomSpike served as roadblocks to instant mining and provide security against 51% attack risk. However, this spike difficulty like a roadblock that makes big ASIC mining less profitable. In case of spike block to be mined, the spike difficulty immediately serve as base difficulty, which will block GPU/ASIC miners effectively and leave CPU cheetah solo miners dominating mining almost 100% until next base difficulty reset.

What is the stable version?

I just compiled bitcoin cash from source, version 0.21.11, and it when I do getblockchaininfo I get the warning:
"warnings": "This is a pre-release test build - use at your own risk - do not use for mining or merchant applications"
So I tried with 0.21.10, 0.21.9, and even 0.21.8. They all give the same warning!
Here's what I did (on Ubuntu 20.04):
apt-get update
apt-get upgrade -y
apt-get install libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-test-dev libboost-thread-dev git bsdmainutils build-essential libssl-dev libevent-dev ninja-build python3 cmake libjemalloc-dev libminiupnpc-dev libdb-dev libdb++-dev libzmq3-dev -y
git clone https://github.com/Bitcoin-ABC/bitcoin-abc --branch v0.21.11 --single-branch
(cd bitcoin-abc && mkdir build && cd build && cmake -GNinja -DBUILD_BITCOIN_QT=OFF .. && ninja && strip src/bitcoind && strip src/bitcoin-cli && strip src/bitcoin-tx && ninja install)
What am I doing wrong? I am planning on mining so I am concerned by this warning.

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.

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?

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).

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.

cold storage compatibility issues

Hello, I have been a fan of electrum because of its offline capability. I like that I can use Bitcoin while storing my private keys on a computer that has the wifi card removed and hot glue stuffed in the Ethernet port. However it looks like maybe the electrum developers have over-promised and under-delivered in this regard. Or, maybe they simply do not have the time, energy, resources to make this work in real life.
Let me explain. I have an old-ass computer that is running Ubuntu 12 (precise), this computer has electrum 2.5.4 installed with a cold-storage wallet that has my private key.
I want to send some bitcoin from that address to a new wallet on my desktop so I can spend the bitcoin. So I installed electrum (newest version 3.3.8) on my desktop, imported the bitcoin address, and created a transaction. Then I sent the transaction to the offline computer out of band, and verified that the out-of-band transmission worked by comparing the hash of the txn file on both the offline and online machines. Then I tried to open the txn file on the offline machine with Electrum 2.5.4. Well, guess what, it didn't work. Electrum 2.5.4 printed to the console:
Traceback (most recent call last):
File "/uslocal/lib/python2.7/dist-packages/Electrum-2.5.4-py2.7.egg/electrum_gui/qt/main_window.py", line 2261, in do_process_from_file

d = TxDialog(tx, parent, desc, prompt_if_unsaved)
File "/uslocal/lib/python2.7/dist-packages/Electrum-2.5.4-py2.7.egg/electrum_gui/qt/transaction_dialog.py", line 48, in __init__

d[inputs] = list(parse_input(vds) for i in xrange(n_vin))
OverflowError: Python int too large to convert to C long
That's pretty frustrating, the first thing I tried was to install Electrum 2.5.4 on my Desktop and try to create a new unsigned transaction with Electrum 2.5.4. However, this is a no-go because old versions of Electrum cannot connect to Electrum servers any more. So I have to try to update the Electrum on the Offline computer. But I'm not even sure if this is possible considering how ubuntu 12 it's definitely out of support at this point and the offline computer does not even have python3 installed, let alone the GTK stuff or whatever is probably required to run Electrum.
I'm starting to regret choosing a GUI-based wallet for my offline storage considering how hard it is to actually use this and how it simply melts over time... even just 5 years is is enough time to completely melt and destroy this software and make it un-usable. Time Catches All. So now I have to go out and buy a new computer that can run the updated OS, so I can install the new version of Electrum, so I can access my bitcoin.
Do you have any other ideas? Has anyone else experienced anything like this?

[IDEA] [PROPOSAL] Monero Debian (deb) packages / Debian package repository deb.getmonero.org (I can do)

I have the skills to implement this if wanted.
Possible User Experience
This is a proposal, i.e. not implemented yet. Instructions for users, simplified.
How to install monero using apt-get
Download the repository signing key.
wget https://www.getmonero.org/monero.asc
Add the signing key.
sudo apt-key --keyring /etc/apt/trusted.gpg.d/monero.gpg add ~/monero.asc
Add APT repository.
echo "deb https://deb.getmonero.org buster main" | sudo tee /etc/apt/sources.list.d/monero.list
Update your package lists.
sudo apt-get update
Install monero.
sudo apt-get install monero
A few technical implementation details
I would simply grab the binaries provided by getmonero.org, download them, check software (gpg) signatures, put these into deb packages, add these to a repository, and upload the repository.
What I would not do is creating the binaries during package creation. While this is nice to have, it doesn't help user experience and blocks the progress on reaching this goal. See next chapter.
Why simply put the pre-build Monero binaries into a deb package?
1) After bitcoin existing for more than 10 years, being popular and being in Debian unstable (sid) it still never made its way into Debian testing, let alone stable. Reason being explained that a difference in underlying libraries (even just security fixes) during compilation may result in a network split. Binaries compiled during packaging on different versions of Linux distributions might have different libraries that might cause a network fork / chain split.
References:
(Note: above website saying Tags: fixed-upstream is probably a mistake as discussion at bottom says.)
2) The github issue of packaging monero stalled.
3) By shipping the same binaries as provided by getmonero.org reduces the chances of introducing a backdoor.
Many Options
Timeline
Doable quickly. The electrum (bitcoin) AppImage was recently added to a Debian package (binaries-freedom) by me and is now easily installable in Whonix. Pre-installed in testers version of Whonix already.
About Me
I am the founder of Whonix, which I am maintaining at present for more than 7 years.
Whonix (formerly TorBOX) is a Debian GNU/Linux–based security-focused Linux distribution. It aims to provide privacy, security and anonymity on the internet.
You can see an overview of packages I am maintaining on my github profile.
To proof that this forum account adrelanos corresponds the same person maintaining whonix.org, it is added here.
Questions
What happened to, what is the successor of the forum funding system?

(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

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.
