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.

Reddcoin (#RDD) May 2020 Team Update, or “New Wallets & What to Expect when You’re Expecting PoSV v2”

Link to Medium post -> https://medium.com/@techadept/reddcoin-rdd-may-2020-team-update-or-what-to-expect-when-youre-expecting-posv-v2-b708319221ce?sk=b5eafc57b67327d99a35380f390d77ca
Hey, ReddHeads!
To new ReddHeads, welcome! To old ReddHeads, welcome back! It’s an exciting time in Reddcoin (RDD) for a lot of reasons, and we, the Reddcoin Core development team, wanted to get a brief update out to touch base on some of the highlights.
Attached are some screenshots of our work to enhance security and interoperability, and to extend support to MacOS Catalina in our newest v3.10.1 wallet.
This wallet release also includes components and performance & security upgrades taken from the Bitcoin 0.10 codebase, and we will be following much of that same development and enhancement in our Reddcoin Core wallet in the future, with 0.11 up next.
This release is not a required upgrade (except for Catalina users), but will benefit user experience and security significantly. We’ll be publishing, of course, a full public changelog, hashes and commit list in Github along with open source code and compiled executables upon release.
But the major changes in Reddcoin v3 are just about to start, as PoSV v2 gets ready to activate. Released to the community on 12/24/19, the blockchain has (at time of writing) reached 8197 of the required 9000 block threshold, or 91.08% of our goal of supermajority. If you haven’t upgraded yet, or aren’t staking, it’s time.
After PoSV v2 activation, older (v2.x, v1.x) wallets will not be able to send transactions or stake.
We anticipate activation to be reached within a very short time period, especially once our Mac ReddHeads are able to participate, and as such we want to ensure that information for the general community is available and up to date.
1) AM I GOING TO LOSE MY REDDCOIN (RDD)??
a. NO. This is a soft-fork, and whether you’ve upgraded to a v3 wallet or not, you cannot lose your coins. The blockchain itself will remain the same, it is only the rules of staking that are changing. Older wallets WILL stop functioning immediately after the threshold is passed and PoSV v2 activates, but all that is required at that point to restore functionality is to install the new v3 wallet. If you need help, please join our Telegram or Discord live chats for community or Dev help directly. No ReddHead left behind!
2) WHAT DO I NEED TO DO??
a. If you’re staking, make sure you’re using a v3 wallet, preferably the latest version. Right now, that is v3.0.1, in a few days with the above noted release it will be v3.10.1. You may also wish to use the “Backup…” function at this time to make sure you have a backup of the only important file you need, the “wallet.dat” file. There are no mobile staking options at this time due to the nature of our PoSV protocol, but you can deposit coins in the dev team-run ReddBot on Telegram to stake if you have no other options until a mobile staking option is made available.
b. If you’re not staking, or are holding on Coinomi, or Guarda, or other 3rd party wallets, or on an exchange, or a paper wallet, you will also have no operational issues, but of course you’re encouraged to help secure the network and validate transactions, by starting to stake.
3) I’M BORED. ENTERTAIN ME!
a. OK. As successful as our first meetup was, we agree. Look for an upcoming benefit concert from Reddcoin and hopscotchmafiamusic.com at the end of this month. No, really. Free awesome music, cool people, come have a bit of fun with the ReddHead community virtually!
4) I’M HUNGRY. FEED ME!
a. Well…with the activation of PoSV v2, and the creation of Reddcoin’s self- funded development mechanism, we’re very excited to be able to provide at least some resources and RDD toward the Reddcoin Community Food & Supply Bank initiative in the near future. Reddcoin Core will also be donating any funds received in connection with the above concert event to worthy and working charities, especially if we can convince them to receive RDD (or BTC). Watch for further info about this and other charity initiatives to come. Our own efforts rely on PoSV v2 activation, but will be documented publicly and transparently as they evolve.
5) I WAS USING RDD AND THEN X (or Y or Z) HAPPENED AND NOW I’M BROKE AND SAD AND ANGRY. HELP ME!
a. Perhaps you’ve not heard about Reddcoin’s uniquely conceived “Reddcoin Restitution Fund”. Been hacked? Lost a few coins when your computer crashed or your brother formatted your hard drive? Reddcoin has committed a percentage of PoSV v2 funding to give back to users legitimately affected by events beyond their control.
Cases of extreme stupidity will be vetted on a case by case basis, obviously fraudulent claims will be laughed at, and all cases will be dependent on a reasonable standard of proof and verification. This is also going to be an evolving and good faith approach to giving back to our real ReddHead community, and will require both transparency and abuse-prevention to be successful, but we look forward to being able to help those who deserve and need it. NOTE: Trading and speculative losses aren’t covered in any of this. Obviously.
6) I WANT TO KNOW MORE!
We’re working right now to rebuild our main website www.reddcoin.com into a more informative and resource-rich site, but it’s a good starting point. We are in the process of updating our roadmap to cover the end of 2020 and the future as well, and both of those should be available and will be announced within the next month.

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).

ALL NEW! – Groestlcoin EasyVanity 2020

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.

(Upvote to the top) > SOLUTION FOR ZCLASSIC Eleos Wallet: "Wallet daemon can not be run. Check if daemon does not already run"

So I noticed a lot of people recently (including myself) are experiencing the error "Wallet daemon can not be run. Check if daemon does not already run" when trying to open up their ZCL Eleos wallet, and people are unable to access their funds or cannot export their private keys as well. A solution to this is now official (thanks to JBrutWhat from the BTCP team for helping me out on this.) Note: Post is being edited as more info becomes available to me.
This solution also works for users who are on the ZClassic Swing wallet experiencing the error "A general unexpected critical error has occurred: error: Couldn't connect to server, see the console output for more detailed error information!."
Eleos Wallet Troubleshooting section
ZClassic Electrum Wallet
  1. Create a new standard wallet and restore the 2FA wallet using your "seed" codes. DO NOT password protect this wallet.
  2. Disable the 2FA feature when presented with the option.
  3. Navigate to C:/Users/YOUR-NAME/AppData/Roaming/Electrum-zcl/wallets. Open the new standard wallet file with Notepad.
  4. You will need to gather the 2 private keys and one public key. To find this easily, press “CTRL+F” and search for “xprv”. Copy the 2 “xprv” values as well as the last “xpub” value. You will need these in a later step.
  5. Create a new “Multi-signature wallet”. Select “From 3 co-signers” on the first slider. Select “Require 2 signatures” on the second slider.
  6. To add the first co-signer, click “Use public or private keys”. Enter the first xprv key in this box.
  7. Add the second co-signer via a private key also.
  8. Add the third co-signer with the public key. Complete the set-up.
  9. Your wallet funds now have the ability to be sent from the multi-signature wallet.
For Users who were already using the Electrum wallet beforehand, you can go to file > new/restore wallet > next > import zclassic private keys and input the private key you obtained from the walletaid tool, and it should import the wallet into the electrum wallet. Then from there, go to file > backup wallet and export a copy of the wallet.dat file onto an offline USB.
Reminder: Backup and delete the private keys file from your desktop pc/hard drive, move it into an offline USB for safekeeping. Do not leave it on an online device.

Zoin Basics: A Beginner’s Guide to Obtaining Zoin

Welcome to Zoin! We want to start by thanking you for joining our amazing community. Zoin is a community-governed decentralized digital currency with privacy features (based on the Zerocoin protocol) and is developed by a diverse team from all around the world. There is no pre-mine and no founder’s reward for Zoin; additionally, it is strictly CPU-minable (see mining section below). Together, these features ensure fairness and transparency to everyone interested in obtaining Zoin. Through this guide you will learn about the current methods of acquiring Zoin for yourself.

How to Earn / Buy Zoin

Right now, there are two ways you can obtain Zoin. You can either use the Bitcoin/Zoin trading pair on Cryptopia exchange or you can mine for Zoin using your own hardware.
 

Method 1: Trading Zoin on Cryptopia

To start, the easiest way to buy a cryptocurrency such as Ethereum or Litecoin is through Coinbase, where you can buy up to $500 worth of Litecoins (for example) using a credit card before you need to verify your identity. Coinbase accepts buyers from 33 countries across the world. A simple guide from Coinbase on buying Litecoin (or Ethereum) with your bank account / credit card is all you need to get started.
Once you have purchased either Litecoin or Ethereum (or another altcoin) you may login to Cryptopia exchange, after you’ve created an account. You must create a deposit address for the same coin that you previously bought on Coinbase or another exchange by clicking deposit under your account, and then typing the name of the coin you wish to deposit. This will generate an address for your Cryptopia trading wallet to receive coins. You can either copy / paste the address (never type it yourself without verifying it), or scan the QR code if you are sending from a mobile wallet.
Once you make a deposit to your Cryptopia wallet address you must wait for several confirmations before your funds are trade-able on Cryptopia. This usually takes around 30 minutes.
When the deposit is confirmed you may go to the Exchange Market section of Cryptopia and search for the coin you just deposited. Once you are there, create a sell order and wait for someone to buy it, or choose a buy order for the coin to trade it for Bitcoin right away. Since you just purchased your cryptocurrency, the price probably won’t be very different than when you bought it, but this depends heavily on the current state of the market. Look up how much the current buy orders are (in your country’s currency), if it is close to the price you bought it at then you can sell at that price. Remember, a sell order may not be filled right away, but choosing someone’s buy order will sell it to them instantly.
If you have successfully traded your altcoin for Bitcoin on Cryptopia, you may now use your Bitcoin to buy Zoin. You can buy Zoin through a buy order of your own (bid) or a sell order from someone else; again, this is entirely up to you and how you anticipate the market / price of coins.
Congratulations, you have successfully bought your first Zoin!
The next step is to transfer the Zoin you bought to your own personal Zoin wallet. To do this, download the wallet on your preferred platform and after installing and running the wallet for the first time, wait for the blockchain to fully sync.
 
  1. Close your wallet (if it’s open).
  2. Delete the following folders from %appdata% on Windows or Library/Application Support/Zoin on Mac: Blocks, Chainstate and the file peers.dat
  3. Download the latest blockchain file, extract using 7Zip or your preferred program.
  4. Paste the newly downloaded folders: Block, Chainstate and file peers.dat in ZOIN folder under %appdata% on Windows or Library/Application Support/Zoin on Mac
  5. Open the wallet and wait for it to synchronize. This should take less time than downloading the entire blockchain and syncing from scratch. The process should take around 30 minutes.
Go to the Receive tab and click on your address, then choose Copy Address. Paste that address on the Cryptopia withdraw page for Zoin and confirm that you want to withdraw. In a few minutes, your Zoin will show up in your wallet (it will be confirmed after 6 confirmations).
 
After your wallet is up to date and you’ve added some of your coins to it, you will want to make it safe in case something happens.
The first thing you want to do is to encrypt it. You can do this by clicking on Settings Encrypt Wallet
You should type in a passphrase that is safe and that you will remember, confirm this passphrase and proceed to encrypt your wallet.
Please be advised, once you set your passphrase you can’t forget it or all your funds will be lost!
Right after your wallet has been encrypted, you should make a backup of it. Click on File Backup Wallet and save the wallet as a wallet.dat file
If you want to open your wallet on another computer you may save the wallet file onto a flash drive or other backup device / method you may already have. Remember that if you encrypted your wallet before doing this backup you must know the passphrase in order to access your wallet.
 
Another way of recovering your wallet is by finding the private key for the wallet. This can be done in the wallet debug terminal (advanced). For accessing your wallet private key, you must do the following procedure:
If your wallet is encrypted: Click Help Debug Window Console (tab). In the console window, use the command walletpassphrase first:
walletpassphrase "YourPassphrase" 60 
Where "YourPassphrase" is the passphrase you used when you encrypted your wallet and 60 is the amount of time you want to unencrypt your wallet for (in seconds).
Next, use the dumpprivkey command in the following form:
dumpprivkey "wallet address" 
Replace "wallet address" with your own wallet address.
After entering these commands, you will receive your private key.
You may now write down and save this private key.
 

Method 2: Mining Zoin

The second way of obtaining Zoin is to earn it by mining, using your own hardware and a mining pool server (we recommend the official pool). Mining Zoin is possible with any modern computer as long as it has a CPU.
To start mining you need to have an account in a “pool”; this is a place where several computers (also known as workers) connect together to mine the blockchain. As we mine the blockchain, we find blocks which contain a reward (currently 12.5 Zoin) which is shared by the number of total miners depending on each person’s mining hashrate. The better your hardware is, the more Zoin you will receive from mining.
To get started, visit our official pool and create your mining account.
You will need to set up a worker. This is your mining device which should be assigned a name and password in order for the network to distinguish your mining rig from others. To do this, visit the Workers page.
The Username must be set for as many workers or computers you want to set up. For example, if the username you chose when signing up to our pool was “john123” and you set your first computer name to worker1. Then your username and worker will be: “john123.worker1”. If you set a second worker as worker2, your second worker name will be “john123.worker2” and so on. The password will be whatever you choose under the password that box, the password can be the same for all the workers.
 
Mining on Windows:
Now that your workers are set, you can go ahead and download mining software, which you can get from the Resources page of the official pool.
Once you have the mining software, open the compressed folder by extracting its contents and create a batch (.bat) file which will contain all the info necessary to mine Zoin into your account. To do this, open a text editor such as Notepad and save the file as .bat instead of .txt
 
This batch file must contain just one line:
cpuminer-aes-avx2.exe -a lyra2zoin -o stratum+tcp://zoin.netabuse.net:3000 -u username.workername -p workerpassword 
 
cpuminer-aes-avx2.exe is the .exe file that you want to use, it depends on your CPU.
Lyra2zoin is the algorithm used by Zoin, that should remain the same.
stratum+tcp://zoin.netabuse.net:3000 is the link to the official pool.
username.workername should be the username you set. (Example: john123.worker1)
workerpassword is the password you set for each worker.
Once you set this batch file, you can run it by double-clicking on it.
 
Note: Make sure that your Firewall / AV program isn’t blocking cpuminer-aes-avx2.exe or the .bat file in order for it to run successfully.
 
Mining on Linux (Advanced):
Type the following into the terminal one line at a time:
 
sudo chown -R $USER: $HOME 
 
sudo apt-get update 
 
sudo apt-get install automake autoconf pkg-config libcurl4-openssl-dev libjansson-dev libssl-dev libgmp-dev -y 
 
sudo apt-get install autotools-dev automake make libcurl4-openssl-dev g++ libssl-dev libgmp3-dev -y 
 
sudo apt-get install build-essential screen automake m4 openssl libssl-dev git libjson0 libjson0-dev libcurl4- openssl-dev autoconf python-software-properties -y 
 
sudo git clone https://github.com/JayDDee/cpuminer-opt 
 
cd cpuminer-opt 
 
./build.sh 
 
./cpuminer -a lyra2zoin -o stratum+tcp://zoin.netabuse.net:3000 -u USERNAME.WORKERNAME -p x -t x 
Replace USERNAME.WORKERNAME with your unique pool username and workername
 
Mining on Mac OS:
  1. Download and install Docker Community Edition
  2. Visit the Zoin Official Pool and create your mining account
  3. Setup a Worker
  4. Edit the line below to match your pool configuration:
 
docker run hmage/cpuminer-opt -a lyra2zoin -o stratum+tcp://zoin.netabuse.net:3000 -u USERNAME.WORKERNAME -p x 
 
hmage/cpuminer-opt is the miner that will be used by docker.
Lyra2zoin is the algorithm used by Zoin, that should remain the same.
stratum+tcp://zoin.netabuse.net:3000 is the link to the official pool.
USERNAME.WORKERNAME should be your unique username and workname (Example: john123.worker1)
If Docker up and running, open Terminal on your Mac (Command + Spacebar and type "Terminal") and paste the line you created. Docker will proceed to download the necessary programs and start mining right away. If you can see the Accepted green message you are mining and you can check all of the mining stats and your earnings from the pool on the main page.
Happy mining!

Lost Bitcoin

I mined bitcoin in 2011 or 2012- How do I find my old wallet?
I know for a fact that sometime in 2011or 2012 I signed up for a mining pool and ran the MacMiner app on my Mac OS X to mine bitcoin. I remember getting a wallet address - does this mean the wallet was for sure on an exchange or could it be in my email that I used back then. I got the old Mac out and tried to search for a wallet.dat file and could not find one but I'm not sure if I would have done this via an exchange or not. Any emails regarding signing up for an exchange or an "online" wallet. would be in an email that I don’t use anymore and I’m trying to recover my old p.w. to get access to that Do I have any hope? Am I searching in vain? What are the chances of recovering any bitcoin if I had that software running for approx. 6 months in 2011/2012 ?
Yes, I barely know what I'm talking about. I know this. Sorry in advance.

1. What is Nexus (NXS)?
Nexus is a digital currency, distributed framework, and peer-to-peer network. Nexus further improves upon the blockchain protocol by focusing on the following core technological principles:
Nexus will combine our in-development quantum-resistant 3D blockchain software with cutting edge communication satellites to deliver a free, distributed, financial and data solution. Through our planned satellite and ground-based mesh networks, Nexus will provide uncensored internet access whilst bringing the benefits of distributed database systems to the world.

2. What benefits does Nexus bring to the blockchain space?
As Nexus has been developed, an incredible amount of time has been put into identifying and solving several key limitations:
Nexus is also developing a framework called the Lower Level Library. This LLL will incorporate the following improvements:
For information about more additions to the Lower Level Library, please visit here
 
3. How does Nexus secure the network and reach consensus?
Nexus is unique amongst blockchain technology in that Nexus uses 3 channels to secure the network against attack. Whereas Bitcoin uses only Proof-of-Work to secure the network, Nexus combines a prime number channel, a hashing channel and a Proof-of-Stake channel. Where Bitcoin has a difficulty adjustment interval measured in weeks, Nexus can respond to increased hashrate in the space of 1 block and each channel scales independently of the other two channels. This stabilizes the block times at ~50 seconds and ensures no single channel can monopolize block production. This means that a 51% attack is much more difficult to launch because an attacker would need to control all 3 channels.
Every 60 minutes, the Nexus protocol automatically creates a checkpoint. This prevents blocks from being created or modified dated prior to this checkpoint, thus protecting the chain from malicious attempts to introduce an alternate blockchain.
 
4. What is quantum resistance and how does Nexus implement it?
To understand what quantum resistance is and why it is important, you need to understand how quantum computing works and why it’s a threat to blockchain technology. Classical computing uses an array of transistors. These transistors form the heart of your computer (the CPU). Each transistor is capable of being either on or off, and these states are used to represent the numerical values 1 and 0.
Binary digits’ (bits) number of states depends on the number of transistors available, according to the formula 2n, where n is the number of transistors. Classical computers can only be in one of these states at any one time, so the speed of your computer is limited to how fast it can change states.
Quantum computers utilize quantum bits, “qubits,” which are represented by the quantum state of electrons or photons. These particles are placed into a state called superposition, which allows the qubit to assume a value of 1 or 0 simultaneously.
Superposition permits a quantum computer to process a higher number of data possibilities than a classical computer. Qubits can also become entangled. Entanglement makes a qubit dependant on the state of another, enabling quantum computing to calculate complex problems, extremely quickly.
One such problem is the Discrete Logarithm Problem which elliptic curve cryptography relies on for security. Quantum computers can use Shor’s algorithm to reverse a key in polynomial time (which is really really really fast). This means that public keys become vulnerable to quantum attack, since quantum computers are capable of being billions of times faster at certain calculations. One way to increase quantum resistance is to require more qubits (and more time) by using larger private keys:
Bitcoin Private Key (256 bit) 5Kb8kLf9zgWQnogidDA76MzPL6TsZZY36hWXMssSzNydYXYB9KF
Nexus Private Key (571 bit) 6Wuiv513R18o5cRpwNSCfT7xs9tniHHN5Lb3AMs58vkVxsQdL4atHTF Vt5TNT9himnCMmnbjbCPxgxhSTDE5iAzCZ3LhJFm7L9rCFroYoqz
Bitcoin addresses are created by hashing the public key, so it is not possible to decrypt the public key from the address; however, once you send funds from that address, the public key is published on the blockchain rendering that address vulnerable to attack. This means that your money has higher chances of being stolen.
Nexus eliminates these vulnerabilities through an innovation called signature chains. Signature chains will enable access to an account using a username, password and PIN. When you create a transaction on the network, you claim ownership of your signature chain by revealing the public key of the NextHash (the hash of your public key) and producing a signature from the one time use private key. Your wallet then creates a new private/public keypair, generates a new NextHash, including the corresponding contract. This contract can be a receive address, a debit, a vote, or any other type of rule that is written in the contract code.
This keeps the public key obscured until the next transaction, and by divorcing the address from the public key, it is unnecessary to change addresses in order to change public keys. Changing your password or PIN code becomes a case of proving ownership of your signature chain and broadcasting a new transaction with a new NextHash for your new password and/or PIN. This provides the ability to login to your account via the signature chain, which becomes your personal chain within the 3D chain, enabling the network to prove and disprove trust, and improving ease of use without sacrificing security.
The next challenge with quantum computers is that Grover’s algorithm reduces the security of one-way hash function by a factor of two. Because of this, Nexus incorporates two new hash functions, Skein and Keccak, which were designed in 2008 as part of a contest to create a new SHA3 standard. Keccak narrowly defeated Skein to win the contest, so to maximize their potential Nexus combines these algorithms. Skein and Keccak utilize permutation to rotate and mix the information in the hash.
To maintain a respective 256/512 bit quantum resistance, Nexus uses up to 1024 bits in its proof-of-work, and 512 bits for transactions.
 
5. What is the Unified Time protocol?
All blockchains use time-stamping mechanisms, so it is important that all nodes operate using the same clock. Bitcoin allows for up to 2 hours’ discrepancy between nodes, which provides a window of opportunity for the blockchain to be manipulated by time-related attack vectors. Nexus eliminates this vulnerability by implementing a time synchronization protocol termed Unified Time. Unified Time also enhances transaction processing and will form an integral part of the 3D chain scaling solution.
The Unified Time protocol facilitates a peer-to-peer timing system that keeps all clocks on the network synchronized to within a second. This is seeded by selected nodes with timestamps derived from the UNIX standard; that is, the number of seconds since January 1st, 1970 00:00 UTC. Every minute, the seed nodes report their current time, and a moving average is used to calculate the base time. Any node which sends back a timestamp outside a given tolerance is rejected.
It is important to note that the Nexus network is fully synchronized even if an individual wallet displays something different from the local time.
 
6. Why does Nexus need its own satellite network?
One of the key limitations of a purely electronic monetary system is that it requires a connection to the rest of the network to verify transactions. Existing network infrastructure only services a fraction of the world’s population.
Nexus, in conjunction with Vector Space Systems, is designing communication satellites, or cubesats, to be launched into Low Earth Orbit in 2019. Primarily, the cubesat mesh network will exist to give Nexus worldwide coverage, but Nexus will also utilize its orbital and ground mesh networks to provide free and uncensored internet access to the world.
 

The Nexus Currency (NXS):

1. How can I get Nexus?
There are two ways you can obtain Nexus. You can either buy Nexus from an exchange, or you can run a miner and be rewarded for finding a block. If you wish to mine Nexus, please follow our guide found below.
Currently, Nexus is available on the following exchanges:
Nexus is actively reaching out to other exchanges to continue to be listed on cutting edge new financial technologies..
 
2. How much does a transaction cost?
Under Nexus, the fee structure for making a transaction depends on the size of your transaction. A default fee of 0.01 NXS will cover most transactions, and users have the option to pay higher fees to ensure their transactions are processed quickly.
When the 3D chain is complete and the initial 10-year distribution period finishes, Nexus will absorb these fees through inflation, enabling free transactions.
 
3. How fast does Nexus transfer?
Nexus reaches consensus approximately every ~ 50 seconds. This is an average time, and will in some circumstances be faster or slower. NXS currency which you receive is available for use after just 6 confirmations. A confirmation is proof from a node that the transaction has been included in a block. The number of confirmations in this transaction is the number that states how many blocks it has been since the transaction is included. The more confirmations a transaction has, the more secure its placement in the blockchain is.
 
4. Did Nexus hold an ICO? How is Nexus funded?
The Nexus Embassy, a 501(C)(3) not-for-profit corporation, develops and maintains the Nexus blockchain software. When Nexus began under the name Coinshield, the early blocks were mined using the Developer and Exchange (Ambassador) addresses, which provides funding for the Nexus Embassy.
The Developer Fund fuels ongoing development and is sourced by a 1.5% commission per block mined, which will slowly increase to 2.5% after 10 years. This brings all the benefits of development funding without the associated risks.
The Ambassador (renamed from Exchange) keys are funded by a 20% commission per block reward. These keys are mainly used to pay for marketing, and producing and launching the Nexus satellites.
When Nexus introduces developer and ambassador contracts, they will be approved, denied, or removed by six voting groups namely: currency, developer, ambassador, prime, hash, and trust.
Please Note: The Nexus Embassy reserves the sole right to trade, sell and or use these funds as required; however, Nexus will endeavor to minimize the impact that the use of these funds has upon the NXS market value.
 
5. Is there a cap on the number of NXS in existence?
After an initial 10-year distribution period ending on September 23rd, 2024, there will be a total of 78 million NXS. Over this period, the reward gradient for mining Nexus follows a decaying logarithmic curve instead of the reward halving inherent in Bitcoin. This avoids creating a situation where older mining equipment is suddenly unprofitable, encouraging miners to continue upgrading their equipment over time and at the same time reducing major market shocks on block halving events.
When the distribution period ends, the currency supply will inflate annually by a maximum of 3% via staking and by 1% via the prime and hashing channels. This inflation is completely unlike traditional inflation, which degrades the value of existing coins. Instead, the cost of providing security to the blockchain is paid by inflation, eliminating transaction fees.

6. What is the difference between the LLD wallet and the Oracle wallet?
Due to the scales of efficiency needed by blockchain, Nexus has developed a custom-built database called the Lower Level Database. Since the development of the LLD wallet 0.2.3.1, which is a precursor to the Tritium updates, you should begin using the LLD wallet to take advantage of the faster load times and improved efficiency.
The Oracle wallet is a legacy wallet which is no longer maintained or updated. It utilized the Berkeley DB, which is not designed to meet the needs of a blockchain. Eventually, users will need to migrate to the LLD wallet. Fortunately, the wallet.dat is interchangeable between wallets, so there is no risk of losing access to your NXS.
 
7. How do I change from Oracle to the LLD wallet?
Step 1 - Backup your wallet.dat file. You can do this from within the Oracle wallet Menu, Backup Wallet.
Step 2 - Uninstall the Oracle wallet. Close the wallet and navigate to the wallet data directory. On Windows, this is the Nexus folder located at %APPDATA%\Nexus. On macOS, this is the Nexus folder located at ~/Library/Application Support/Nexus. Move all of the contents to a temporary folder as a backup.
Step 3 - Copy your backup of wallet.dat into the Nexus folder located as per Step 2.
Step 4 - Install the Nexus LLD wallet. Please follow the steps as outlined in the next section. Once your wallet is fully synced, your new wallet will have access to all your addresses.
 
8. How do I install the Nexus Wallet?
You can install your Nexus wallet by following these steps:
Step 1 - Download your wallet from www.nexusearth.com. Click the Downloads menu at the top and select the appropriate wallet for your operating system.
Step 2 - Unzip the wallet program to a folder. Before running the wallet program, please consider space limitations and load times. On the Windows OS, the wallet saves all data to the %APPDATA%\Nexus folder, including the blockchain, which is currently ~3GB.
On macOS, data is saved to the ~/Library/Application Support/Nexus folder. You can create a symbolic link, which will allow you to install this information in another location.
Using Windows, follow these steps:
On macOS, follow these steps:
Step 3 (optional) - Before running the wallet, we recommend downloading the blockchain database manually. Nexus Earth maintains a copy of the blockchain data which can save hours from the wallet synchronization process. Please go to www.nexusearth.com and click the Downloads menu.
Step 4 (optional) - Extract the database file. This is commonly found in the .zip or .rar format, so you may need a program like 7zip to extract the contents. Please extract it to the relevant directory, as outlined in step 2.
Step 5 - You can now start your wallet. After it loads, it should be able to complete synchronization in a short time. This may still take a couple of hours. Once it has completed synchronizing, a green check mark icon will appear in the lower right corner of the wallet.
Step 6 - Encrypt your wallet. This can be done within the wallet, under the Settings menu. Encrypting your wallet will lock it, requiring a password in order to send transactions.
Step 7 - Backup your wallet.dat file. This can be done from the File menu inside the wallet. This file contains the keys to the addresses in your wallet. You may wish to keep a secure copy of your password somewhere, too, in case you forget it or someone else (your spouse, for example) ever needs it.
You should back up your wallet.dat file again any time you create – or a Genesis transaction creates (see “staking” below) – a new address.
 

Types of Mining or Minting:

1.Can I mine Nexus?
Yes, there are 2 channels that you can use to mine Nexus, and 1 channel of minting:
Prime Mining Channel
This mining channel looks for a special prime cluster of a set length. This type of calculation is resistant to ASIC mining, allowing for greater decentralization. This is most often performed using the CPU.
Hashing Channel
This channel utilizes the more traditional method of hashing. This process adds a random nonce, hashes the data, and compares the resultant hash against a predetermined format set by the difficulty. This is most often performed using a GPU.
Proof of Stake (nPoS)
Staking is a form of mining NXS. With this process, you can receive NXS rewards from the network for continuously operating your node (wallet). It is recommended that you only stake with a minimum balance of 1000 NXS. It’s not impossible to stake with less, but it becomes harder to maintain trust. Losing trust resets the interest rate back to 0.5% per annum.
 
2. How do I mine Nexus?
As outlined above, there are two types of mining and 1 proof of stake. Each type of mining uses a different component of your computer to find blocks, the CPU or the GPU. Nexus supports CPU and GPU mining on Windows only. There are also third-party macOS builds available.
Please follow the instructions below for the relevant type of miner.
 
Prime Mining:
Almost every CPU is capable of mining blocks on this channel. The most effective method of mining is to join a mining pool and receive a share of the rewards based on the contribution you make. To create your own mining facility, you need the CPU mining software, and a NXS address. This address cannot be on an exchange. You create an address when you install your Nexus wallet. You can find the related steps under How Do I Install the Nexus Wallet?
Please download the relevant miner from http://nexusearth.com/mining.html. Please note that there are two different miner builds available: the prime solo miner and the prime pool miner. This guide will walk you through installing the pool miner only.
Step 1 - Extract the archive file to a folder.
Step 2 - Open the miner.conf file. You can use the default host and port, but these may be changed to a pool of your choice. You will need to change the value of nxs_address to the address found in your wallet. Sieve_threads is the number of CPU threads you want to use to find primes. Ptest_threads is the number of CPU threads you want to test the primes found by the sieve. As a general rule, the number of threads used for the sieve should be 75% of the threads used for testing.
It is also recommended to add the following line to the options found in the .conf file:
"experimental" : "true"
This option enables the miner to use an improved sieve algorithm which will enable your miner to find primes at a faster rate.
Step 3 - Run the nexus_cpuminer.exe file. For a description of the information shown in this application, please read this guide.
 
Hashing:
The GPU is a dedicated processing unit housed on-board your graphics card. The GPU is able to perform certain tasks extremely well, unlike your CPU, which is designed for parallel processing. Nexus supports both AMD and Nvidia GPU mining, and works best on the newer models. Officially, Nexus does not support GPU pool mining, but there are 3rd party miners with this capability.
The latest software for the Nvidia miner can be found here. The latest software for the AMD miner can be found here. The AMD miner is a third party miner. Information and advice about using the AMD miner can be found on our Slack channel. This guide will walk you through the Nvidia miner.
Step 1 - Close your wallet. Navigate to %appdata%\Nexus (~/Library/Application Support/Nexus on macOS) and open the nexus.conf file. Depending on your wallet, you may or may not have this file. If not, please create a new txt file and save it as nexus.conf
You will need to add the following lines before restarting your wallet:
Step 2 - Extract the files into a new folder.
Step 3 - Run the nexus.bat file. This will run the miner and deposit any rewards for mining a block into the account on your wallet.
For more information on either Prime Mining or Hashing, please join our Slack and visit the #mining channel. Additional information can be found here.
 
3. How do I stake Nexus?
Once you have your wallet installed, fully synchronized and encrypted, you can begin staking by:
After you begin staking, you will receive a Genesis transaction as your first staking reward. This establishes a Trust key in your wallet and stakes your wallet balance on that key. From that point, you will periodically receive additional Trust transactions as further staking rewards for as long as your Trust key remains active.
IMPORTANT - After you receive a Genesis transaction, backup your wallet.dat file immediately. You can select the Backup Wallet option from the File menu, or manually copy the file directly. If you do not do this, then your Nexus balance will be staked on the Trust key that you do not have backed up, and you risk loss if you were to suffer a hard drive failure or other similar problem. In the future, signature chains will make this precaution unnecessary.
 
4. I am staking with my Nexus balance. What are interest rate, trust weight, block weight, and stake weight?
These items affect the size and frequency of staking rewards after you receive your initial Genesis transaction. When staking is active, the wallet displays a clock icon in the bottom right corner. If you hover your mouse pointer over the icon, a tooltip-style display will open up, showing their current values.
Please remember to backup your wallet.dat file (see question 3 above) after you receive a Genesis transaction.
Interest Rate - The minting rate at which you will receive staking rewards, displayed as an annual percentage of your NXS balance. It starts at 0.5%, increasing to 3% after 12 months. The rate increase is not linear but slows over time. It takes several weeks to reach 1% and around 3 months to reach 2%.
With this rate, you can calculate the average amount of NXS you can expect to receive each day for staking.
Trust Weight - An indication of how much the network trusts your node. It starts at 5% and increases much more quickly than the minting (interest) rate, reaching 100% after one month. Your level of trust increases your stake weight (below), thus increasing your chances of receiving staking transactions. It becomes easier to maintain trust as this value increases.
Block Weight - Upon receipt of a Genesis transaction, this value will begin increasing slowly, reaching 100% after 24 hours. Every time you receive a staking transaction, the block weight resets. If your block weight reaches 100%, then your Trust key expires and everything resets (0.5% interest rate, 5% trust weight, waiting for a new Genesis transaction).
This 24-hour requirement will be replaced by a gradual decay in the Tritium release. As long as you receive a transaction before it decays completely, you will hold onto your key. This change addresses the potential of losing your trust key after months of staking simply because of one unlucky day receiving trust transactions.
Stake Weight - The higher your stake weight, the greater your chance of receiving a transaction. The exact value is a derived by a formula using your trust weight and block weight, which roughly equals the average of the two. Thus, each time you receive a transaction, your stake weight will reset to approximately half of your current level of trust.
