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.

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.

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).

Remastered! – Groestlcoin WPF Desktop Wallet (v2.19.0.18)

Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode.
This wallet was previously deprecated but has been brought back to life with modern standards.

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.

Running a Bitcoin node on a $11.99 SBC

Running a Bitcoin node on a $11.99 SBC
Just wanted to let you guys know that I'm successfully running a (pruned) Bitcoin node + TOR on a $11.99 single board computer (Rock Pi S).
The SBC contains a Rockchip RK3308 Quad A35 64bit processor, 512MB RAM, RJ45 Ethernet and USB2 port and I'm using a 64GB SDCard. It runs a version of Armbian (410MB free). There's a new version available that even gives you 480MB RAM, but I'm waiting for Bitcoin Core 0.19 before upgrading.
To speed things up I decided to run Bitcoin Core on a more powerful device to sync the whole blockchain to an external HDD. After that I made a copy and ran it in pruned mode to end up with the last 5GB of the blockchain. I copied the data to the SD card and ran it on the Rock Pi S. After verifying all blocks it runs very smoothly. Uptime at the moment is 15 days.
I guess you could run a full node as well if you put in a 512GB SDcard.
The Rock Pi S was sold out, but if anybody is interested, they started selling a new batch of Rock Pi S v1.2 from today.
Screenshot of resources being used
Bitcoin Core info
Around 1.5 GB is being transferred every day
---
Some links and a short How to for people that want to give it a try:
  1. This is the place where I bought the Rock Pi S.
  2. Here you find more information about Armbian on the Rock Pi S. Flash it to your SDCard. Follow these instructions.
  3. Disable ZRAM swap on Armbian. If you don't do this eventually Bitcoin Core will crash. nano /etc/default/armbian-zram-config ENABLED=false
  4. Enable SWAP on Armbian sudo fallocate -l 1G /swapfile sudo chmod 600 /swapfile sudo mkswap /swapfile sudo swapon /swapfile sudo swapon --show sudo cp /etc/fstab /etc/fstab.bak echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
  5. Set up UFW Firewall sudo ufw default deny incoming sudo ufw default allow outgoing sudo ufw allow ssh # we want to allow ssh connections or else we won’t be able to login. sudo ufw allow 8333 # port 8333 is used for bitcoin nodes sudo ufw allow 9051 # port 9051 is used for tor sudo ufw logging on sudo ufw enable sudo ufw status
  6. Add user Satoshi so you don't run the Bitcoin Core as root sudo adduser satoshi --home /home/satoshi --disabled-login sudo passwd satoshi # change passwd sudo usermod -aG sudo satoshi # add user to sudo group
  7. Download (ARM64 version) and install Bitcoin Core Daemon
  8. Download and install TOR (optional). I followed two guides. This one and this one.
  9. Create a bitcoin.conf config file in the .bitcoin directory. Mine looks like this: daemon=1 prune=5000 dbcache=300 maxmempool=250 onlynet=onion proxy=127.0.0.1:9050 bind=127.0.0.1 #Add seed nodes seednode=wxvp2d4rspn7tqyu.onion seednode=bk5ejfe56xakvtkk.onion seednode=bpdlwholl7rnkrkw.onion seednode=hhiv5pnxenvbf4am.onion seednode=4iuf2zac6aq3ndrb.onion seednode=nkf5e6b7pl4jfd4a.onion seednode=xqzfakpeuvrobvpj.onion seednode=tsyvzsqwa2kkf6b2.onion #And/or add some nodes addnode=gyn2vguc35viks2b.onion addnode=kvd44sw7skb5folw.onion addnode=nkf5e6b7pl4jfd4a.onion addnode=yu7sezmixhmyljn4.onion addnode=3ffk7iumtx3cegbi.onion addnode=3nmbbakinewlgdln.onion addnode=4j77gihpokxu2kj4.onion addnode=5at7sq5nm76xijkd.onion addnode=77mx2jsxaoyesz2p.onion addnode=7g7j54btiaxhtsiy.onion ddnode=a6obdgzn67l7exu3.onion
  10. Start Bitcoin Daemon with the command bitcoind -listenonion
Please note that I'm not a professional. So if anything above is not 100% correct, let me know and I will change it, but this is my setup at the moment.

How to get a public static ip for your local lightning node

My lightning node is a node that is running locally on my server hardware in my house down under, far from the New Jersey Digitalocean datacenter, which is what will come up if you look up the ip of the node. This is done via an OpenVPN tunnel from your local machine to a VPS. I am doing this by renting a VPS from Digitalocean for $20 a month (2 vCPUs, 2GB RAM) running Ubuntu 18.04. You can do this just as easily on a $5 a month VPS with 1 vCPU and 1GB RAM or even a $2.50 a month VPS from Vultr with 512MB RAM. I needed the extra power because I have many web services running there as well.
This setup allows me to have a highly available lightning node, not affected by my home IP address changing. If you are using a mobile connection or have a CGNAT, you wont be able to port forward for your lightning node. This setup allows you to do so. You can also use this to make a portable lightning node, which can get you a full lightning node wherever you have power and internet, without having to mess with network settings. If you don't want others to know your home IP, this is a good option for privacy.
  1. Setup a local lightning node, preferably on a linux machine. I followed the Raspibolt tu`ial (with some tweaks) on a 2 vCPU and 8GB RAM VM running Ubuntu 16.04.
  2. Get a VPS with a static IP address. Digitalocean and Vultr VPSs already are. This VPS wont need much power, so get the cheapest one you can.
  3. Secure the VPS. I used this tutorial. Essentially, setup a non root user, use ssh keys, and setup ufw. Also make sure to allow port 9735 through ufw for lightning. I also additionally made adjustments to the ssh config and installed fail2ban.
  4. Setup an OpenVPN server on the VPS. I used this tutorial.
  5. Install on OpenVPN client on the local linux machine and connect to the server. The tutorial from step 4 shows how to this. Keep this connected for step 6.
  6. SSH into the VPS and figure out the OpenVPN IP address of the client. It should be 10.8.0.x. To figure out the x, setup a simple python web server or something on the local machine on port 8000 or something and open the port on ufw in the local machine. Keep the OpenVPN connection, and use a new ssh session when accessing your local machine. Don't kill the OpenVPN connection, as it may complicate things when finding the ip.
    mkdir testweb
    cd testweb
    echo hello >> index.html
    sudo ufw allow 8000
    python -m SimpleHTTPServer 8000
  7. SSH back into the VPS. Run the curl command below, and try all the numbers between 2-10 for x. When you get hello as your output, then you found the right IP. I found mine at 6. You may have to try higher numbers, but this is unlikely. You can kill your python webserver on your local machine once you find it.
    curl 10.8.0.x:8000
  8. Once you have the IP, you want to make this static, so it doesn't change when you reconnect. This is done on the VPS side, so ssh back into the VPS. This tutorial worked for me. Just make sure to change values like the CommonName and and the IP to match yours (client1 and 10.8.0.x). If it doesn't work search "make openvpn ip static" and look around.
  9. SSH into your local machine, and make the OpenVPN connection persistent. You can kill the OpenVPN connection now. Doing this and this worked for me. If it doesn't work search "openvpn keepalive" or "openvpn auto connect linux" or "make openvpn connection persistent linux".
  10. Restart your local machine, and make sure it connects on boot. Do the python webserver test again, and make sure the same ip is shown on the VPS, and it is still accessible.
  11. SSH back into the VPS. Now, you have to port forward with iptables. you have to add the 2 lines below starting with -A PREROUTING in the same place in your /etc/ufw/before.rules file. Here is what mine looks like. Change the x to your OpenVPN IP. Do sudo ufw disable and sudo ufw enable to restart ufw to update your changes.
    *nat
    :POSTROUTING ACCEPT [0:0]
    -A PREROUTING -i eth0 -p tcp -m tcp --dport 9735 -j DNAT --to-destination 10.8.0.x:9735
    -A PREROUTING -i eth0 -p udp -m udp --dport 9735 -j DNAT --to-destination 10.8.0.x:9735
    -A POSTROUTING -s 10.8.0.0/8 -o eth0 -j MASQUERADE
    COMMIT
  12. SSH into your local machine. Change your lnd.conf to match with this setup, like changing the externalip. Here is what my config looks like, a slight tweak from the Raspibolt one:
    [Application Options]
    debuglevel=info
    maxpendingchannels=5
    alias=GCUBED [LND]
    color=#68F442
    listen=0.0.0.0:9735
    externalip=157.230.95.74:9735
    [Bitcoin]
    bitcoin.active=1
    bitcoin.mainnet=1
    bitcoin.node=bitcoind
    [autopilot]
    autopilot.active=1
    autopilot.maxchannels=5
    autopilot.allocation=0.6
  13. Do a sudo service lnd restart to restart lnd and apply the changes. Remember to do a lncli unlock after any restarts. Your lnd node should now have a public static ip. Look it up a few hours after you do this on 1ml, your ip should be the one of your VPS now.
I am monitoring this for free with uptimerobot. It will notify you if it has gone down. So far mine has been running for 3 days and hasn't gone down.
EDIT: Formatting
EDIT 2: The main reason I didn't use a ddns or a hidden service was mainly for high uptime, and low latency. I am planning on developing a lapp with this node and I didn't want to risk any downtime. Running lightning as a hidden service is a great idea as well, this tutorial shows how to achieve something similar with the clearnet.
EDIT 3: You can achieve a similar result from using TOR

A response to the GRS Shill cries

First of all, I think it is right to say that it wouldn’t be fair for the recent reddit to be entirely attributed to the recent 130% rise in GRS price – The price has gone a lot higher when SegWit was activated and a lot higher in the runup to the previous release announcement (22nd September) and was arguably at the ‘floor’ when it was discovered by us.
I’d like to give a little bit of a backstory on the recent discovery of GRS by a small group of people in a hope you realise this isn’t just shilling some shit-coin for a pump and dump. It was never our intention to come across as shilling and certainly not our intention to attract ‘pump and dump’ groups. We merely searched for SegWit-activated coins, and the main one that kept popping up was Groestlcoin, in posts that didn’t even mention Litecoin or Vertcoin. We thought that it was worth investigating further and decided to do some more research, and the more we found we more we realised that this was a genuine diamond amongst the rocks. 254th in market cap, first to activate SegWit, Lightning Network in full development, the list was endless – and seemingly nobody knew about it which was insanity.
In several places we saw that no marketing was done or being actively planned, and it was up to the community to market the coin if they wanted to whilst the 20+ developers keep cracking on to try and be the first to more developments.
We contacted the lead developer, ‘Jackielove4u’ and started a plan to try and market the coin, first by creating a Discord channel for discussions and then by trying to get their great features out to the world and aim for slow-and-steady growth.
In hindsight, a bit more finesse would have been better and the reddit posts got a little out-of-hand, if I didn’t know any better I would have seen GRS as a coin being shilled too on Reddit, and I have accused people of doing the same with Vertcoin in the past. So I thought I’d try to clear up some misconceptions and give one targeted response post to the cries of shilling and try to give the facts to the best of my knowledge, whilst trying to give an unbias opinion as much as I can based on my views and the views of the response that we’ve had.
PROS:
• Segwit Enabled Enabled first)
• Low-Power Mining – This is a selling point but people have said the power consumption is on-par with Vertcoin. I think the mining uses 2 rounds of Groestl algorithm hashing to make it more secure but is still very low on power consumption and hardware wear
• Lightning Network currently in development
• They have had an easy miner solution since 2015 – Although I’d be the first to admit it is a little clunky, but is openly on Git for improvements.
• 3 iOS wallets (Including a shared wallet), 11 android wallets (1x Secure BIP147, 1x Including sending GRS via SMS, 1x ability to use NFC tags as encryption keys), 11 blackberry wallets (Secure), 3 web wallets and 10 desktop wallets with varying features / designs – More to come on the differences soon.
• Over 80 electrum servers
• Working testnet
• Hosts their own block explorer
• Officially maintained by the Bitcoin Debian packaging team
• Ubuntu PPA available
• ASIC resistant, profitable CPU and GPU mining (And has an ARM miner apparently!) We’re just brushing the surface of the great tech that is being developed by the GRS developers.
CONS:
• Elephant in the room – The name. People have called it ugly, most don’t know how to pronounce it (It’s Groosel-coin). The developers are open to a rebrand pending a community vote in 2018.
• I’ve heard a few times ‘that logo looks like a cross between google and wordpress’. Again the logo is open to rebrand/redesign pending a vote (open for suggestions/examples!) but there is some significance in it. The ‘2’ in the logo is for the 2 rounds of Groestl algorithm hashing that is used.
• Obviously little or no marketing up until this point. Marketing is important (if not vital) for the success of a coin so we’re trying to spread some awareness.
• Lots of internet posts saying that it is a scam coin. From what I can see it seems to be because the coin has been ‘pumped-and-dumped’ a few times? By that logic, most coins are scam coins? The block reward dropped 6% a week when it was first launched specifically to prevent pump-and-dumps.
• Rumours of a pre-mine of 0.2% (240,000 coins) when it was first created. I haven’t gotten to the bottom of this to confirm or deny, but if it was true it seems to have been given as rewards for some early marketing (where those odd naked women pictures come from) and some early bounty rewards to get the ball rolling. No pre-mine is ideal but its personally something I can look over now if it IS true.
• Over 70% of the mined coins are owned by the top 100 addresses. Again, this is clearly an issue that many other coins also are facing (albeit some to a lesser extent). I can only guess that the more time that passes being a lesser-known coin, the greater risk that this becomes as the same miners mine for a longer period of time. Not sure if this matters much but it’s also worth noting that 24% of the mined coins appear to be on Bittrex currently.
TL:DR – Trying not to shill GRS, just trying to get the word out. Criticisms about the coin have been noted by the developers and they are very open to change and improvements suggested if they are the popular vote. I recommend that you research more into the coin, coin the discord on https://discord.gg/8VURndr and make a decision based on your own research whether you'd see something in, and like to support the coin.
Apologies for such a long post..

(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.
