Groestlcoin 6th Anniversary Release


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?

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.
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.


Live Version (Not Recommended)



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).




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.


Remastered Improvements



ALL NEW! – BIP39 Key Tool

Groestlcoin BIP39 Key Tool is a GUI interface for generating Groestlcoin public and private keys. It is a standalone tool which can be used offline.



Linux :
 pip3 install -r requirements.txt python3 bip39\ 


ALL NEW! – Electrum Personal Server

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

UPDATED – Groestlcoin Sentinel 3.5.06 (Android)

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

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= bind= #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.

A slightly overboard response to my threat model.

For what I hope are obvious reasons, I don't want, and probably will never post my threat model publicly online. However, regardless of that, what I'm sure you will extrapolate from this post is that I live my life, digitally in particular, with a fairly high level threat model. This is not because I'm some super sophisticated criminal mastermind, but rather, I am at this level because I genuinely love playing around with this stuff. And I just happen to understand the importance of privacy and just how vital it is to a truly healthy society. I would like to extend a thanks to ProgressiveArchitect for the sharing of the knowledge they have done on this subreddit, /privacytoolsio, and the like. We may have never interacted, but nevertheless, your input into this community is truly interesting and extremely informative and educating. I'm sure those of you familiar with PA's setup will be able to draw some parallels with mine and their's.
Thank you.
I hope you all enjoy reading this write up.
I run Qubes OS on a Lenovo ThinkPad X230 laptop. Specs for it are as following: - i7-3520M - 16GB RAM - 1TB Samsung 860 Evo SSD - Qualcomm Atheros AR9285 wireless card
Additionally, I used a Raspberry Pi Model 3B+ and a Pomono SPI clip to replace the stock BIOS firmware with coreboot+me_cleaner. This wasn't done out of any "real" concern for the Intel ME (though of course proprietary black-boxes like it should be avoided at all costs and not trusted), but rather for open source enthusiasm and for increased security and faster boot times than what the stock BIOS firmware allows for. On that note about the ME, I don't believe the conspiracy theories that claim that it is a state-sponsored attack method for surveillance. I believe that Intel had good intentions for improving the lives of IT professionals who need to manage hundreds, if not thousands of remote machines. However, it has proven time and time again to be insecure, and I don't need the remote management and the "features" that it provides on my machines.
In Qubes, I use a combination of AppVMs and StandaloneVMs for a variety of different purposes. All VMs use PVH over HVM, except for the Mirage Unikernel Firewall, which uses PV, and the sys-net and sys-usb StandaloneVMs which have to use HVM because of PCI device passthrough. Right now most of my VMs are AppVMs, but for maintenance and compartmentalization reasons, I am considering moving more towards StandaloneVMs, despite the increase in disk space and bandwidth usage for updates.
General route of from Qubes to the Internet for anonymous browsing, general private browsing, accessing Uni services, and Uni-related anonymous browsing respectively: 1. Qubes->sys-mirage-firewall->sys-vpn-wg->sys-corridor->sys-whonix->whonix-ws-15-dvm to the internet. 2. Qubes->sys-mirage-firewall->sys-vpn-wg to the Internet. 3. Qubes->sys-mirage-firewall->uni-vpn-wg to the Internet. 4. Qubes->sys-mirage-firewall->uni-vpn-wg->uni-corridor->uni-whonix->uni-anon-research to the Internet.

(Note: the VPN name is substituted in the "vpn" above. I had to remove it to comply with this subreddit's rules. It is easy to identify what VPN it is as it randomly generates a long numaric string and has fantastic support for WireGuard.)

Web Browsers: - Tor Browser (primary) in a disposable Whonix VM. - Firefox (secondary) with the about:config changes listed on and the following extensions: Cookies AutoDelete, Decentraleyes, HTTPS Everywhere, uBlock Origin (advance user, all third party content blocked and JavaScript disabled), and Vim Vixen. Used in my personal AppVM. - Ungoogled Chromium (Uni only) with standard uBlock Origin and cVim. Used only for Uni-related access in my uni-campus and uni-home AppVMs.
Search Engine: SearX, Startpage, and DuckDuckGo.
Password Manager: KeePassXC.
Office: LibreOffice.
Notes: Standard Notes.
Messaging: Signal Desktop.
Media Playback: mpv.
Emails: I access my personal email within my personal Qubes domain and my Uni email using my Uni Qubes domains. My emails are downloaded to a local repository using isync, send using msmtp, and read using neomutt with html emails converted to plain text using w3m. Emails are sent in plain text too. All of the attachments in the emails (PDFs mostly) are automatically opened in DisposableVMs.
My personal Posteo email account has incoming encryption setup. This means that I emailed my public GPG key to an address correlated to my actual Posteo email address so that all email that I receive is encrypted with my public key and can only be decrypted using my private key. So even if my emails were intercepted and/or my account broken into, the contents of them are safe since they are encrypted as soon as they hit Posteo's servers.
I have setup a number of Posteo aliases that are completely segregated from the email I used to register my account. One of those is considered my "professional" email for my current job. I have another couple aliases, one dedicated for 33mail and another dedicated for Abine Blur. I make use of 33mail alias addresses for catch-all email addresses for registering for accounts that need to be under a username associated with my name anyways. This is for purposes like putting different compartmentalized, but still related emails to put onto my Resume. I use a different alias for each Resume I put out online. That way, when that information gets sold, traded, etc., I can easily trace it back to who sold the information. For example, if I applied for a job online that required me to go through the process of registering an account through a third-party, say 'xyz Inc', the address I would register that account with would be [email protected], or something along those lines. Abine Blur is used much in the same manner but for accounts that don't need to be associated with my real name in any way, say online shopping on Amazon that I do under an many aliases, then ship to various address that I don't live at, but that I can visit with no problems. I use a different Blur address with each service like with 33mail for the same reasoning shown above.
The passwords for the accounts are encrypted and stored locally in each of the domains, however, my private key is stored in my vault domain, so even if an adversary were to compromise the domains, they wouldn't be able to steal my private key without exploiting the hypervisor. They would only be able to wait for me to authorize the usage of my private key in that domain, and even then, it could only be used to decrypt files. That is a concern that they can use my private key to decrypt messages, but they wouldn't be able to steal the key. With my personal email, the emails would also be encrypted locally anyway so they wouldn't be able to read them. My Uni email, in contrast, uses Outlook unfortunately, so there isn't any option to enable incoming encryption, and even if it was, I'm not sure how private it would be anyways.
For those looking for an in depth list of all my VMs, with explanations for the more obscure ones, I have listed them below. I have got a lot of templates, hence why I am considering moving over to StandaloneVMs, but as of right now:




Phone: Motorola Moto G5s running Lineage OS 16.0 Pie no G-Apps or micro-G with the following Apps: - AdAway: Open Source hosts file-based ad blocker. (Requires root.) - AFWall+: Linux iptables front end. (Requires root.) - Amaze: File manager. - andOPT: 2FA app. I like it since it can export the entries to an AES encrypted file. - AntennaPod: Podcast manager. - AnySoftKeyboard - Simple Calendar - Simple Contacts Pro - DAVx5: CalDav syncronization with my calendar on my Posteo email account. - F-Droid - Fennec F-Droid: Web Browser. Has the same Firefox addons like on Qubes minus Vim Vixen. I used the app Privacy Settings to configure the about:config. - KeePassDX: Password manager. - KISS launcher - Magisk Manager - NewPipe: YouTube app replacement. - S.Notes: Standard Notes. - OsmAnd~: Maps and navigation. - Red Moon: Blue light filter. - SELinuxModeChanger: Exactly as it sounds. (Requires root.) - Shelter: Work profile manager. - Signal: Messaging. - Vinyl Music Player: Music player. - WireGuard: VPN protocol frontend. Is configured to use my VPN account. Is setup as an always-on and connected VPN.
As mentioned, I use Shelter to manage my work profile. In it I isolate the following apps: - Clover: *chan browser. - Orbot: For routing apps through Tor. Is setup as an always-on and connected VPN. - RedReader: Reddit client. - Tor Browser
Over the last several years, I have started using my phone less and less and taking advantage of less of what it has got to offer. I don't check email on my device. I have no real need to browse the Internet on it outside of watching videos using NewPipe, browsing Reddit, and various *chan boards.
On the Smart Phone side of things, I am considering purchasing an older used iPhone SE or 6S for use with MySudo when outside of my home as well as an iPod Touch for use on WiFi only for use inside my home. The iPhone would be kept inside of a faraday bag when I am at home and not using it. It would also be kept in the faraday bag whenever at home to avoid associating that device with my home address. The iPod Touch would be used for MySudo calls instead.
Future outlook and plan for my privacy and security:
To avoid as much deanonymisation of my privacy as possible, I'm only going to specify enough so that anyone reading this can get the jist of my situation in life. I am quite young (age 16 to 25) and I started along this privacy journey when I was even younger. I was never a very heavy social media user, however I did have an online presence if you looked hard enough. My name fortunately is a very common and short name, so that does help to bury information that I was not able to remove further in the vast trenches that is the Internet.
On the digital side of things, I mentioned that I have a dedicated Crypto AppVM for handling crypto currency transactions using Bisq. I have setup a dedicated bank account that I have periodically been transferring money into so that I can trade crypto. Unfortunately, I do not live in the US, so being able to effectively start trades with others is more difficult. I also do not have access to a credit card masking account like (that I absolutely would use given the ability). I plan on getting an anonymous VPS to host my own Tor exit node for better speeds and to mitigate the possibility of malicious exit nodes. The country I live in has been a proponent of absolute dragnet surveillance on all activities occurring online and in real life, though the former is far more visible on this subreddit. I will be using crypto with cleaned Bitcoin (as seen with ProgressiveArchitect's setup) for purchasing my VPN service, etc.
With future hardware, to replace my aging laptop, I am very hopeful for Xen, then eventually Qubes OS getting ported to Power9. When that happens I'll be getting a Raptor Computing Blackbird as a desktop. Maybe in the future I'll get a Purism Librem laptop, but for now my corebooted X230 works perfectly for my use cases. On that note, I have successfully build the Heads firmware for the X230 and I was able to get the minimal 4MB image flashed on my laptop. I did revert it back to my coreboot setup after playing around a little with it, and unfortunately I haven't had time since to do a full, complete flash of it.
On the physical/real life side of things, I plan on making use of various Trusts in order to hold assets, say to keep my name from being immediately visible on the title of my car. As of right now I am fortunate enough to have the title of my car under the name of someone who I trust. Unless I am legally required, and where there are immediate and absolute consequences, I use fake names in real life. With Uni, I am enrolled under my real name and address. This is a requirement and it is verified, so there is nothing that I can realistically do about it. As for other services, I plan on setting up a personal mailbox (PMB), etc if possible to use as a real, physical address that is associated with my real name and that is used for things like Government issued ID. In the future when I move again, I plan on renting a place in cash to try and keep my name dissociated with my real address. For those looking for reasoning on why one would want to do that, please read How to be Invisible by J.J. Luna. It's truly the Bible of physical privacy.
At this stage I am just going off on a ramble, so I should cut it short here.
I have just started and I live for this shit.

Bfgminer no longer works with Bitcoin Core 0.18.0

I use bfgminer as a stratum proxy running on rpi and connected to my BTC full node. Few friends of mine are mining using my stratum, but the setup stopped working as soon as i updated Bitcoin Core to 0.18.0. All was fine with previous version 0.17.1. My rpi can reach rpc port and also authentication is fine. I use same credentials for a long time on a web service to display info about my node and it works.
I didn’t not find in a changelog anything what could explain it.
What could be the problem? Is there any other sw i can run as stratum proxy on rpi?

/r/Monero - Newcomers Please Read. Everything You Need To Know.

What is Monero (XMR)?
Monero is a secure, private, untraceable (crypto-)currency. It is open-source and freely available to all. Don't believe us? Click here.
Monero is a tool that people can actually use. It makes receiving payments hassle-free, since merchants and individuals no longer need to fear the source of funds they are accepting. With transparent systems like Bitcoin, Ethereum, Verge, or Dash, these people need to hope (or spend substantial resources verifying) the sender did not use the funds illicitly. Furthermore, merchants do not want all their vendors known, and individually do not want everyone to know how much they are spending. If I spend more than I should at Newegg (store), that's my own business.
Monero is different because every transaction is always private. There is no way for pools and exchanges to opt out of sending private transactions. Thus, Monero's anonymity set far exceeds any other coin's anonymity set. Over 86,000 transactions in the past month of August, 2017 hid the sender and receiver, and about 99.95% of them also hid the amount (will increase to 100% of all new transactions in September)! There is no suspicion in using a private transaction, since all transactions are private. A single transaction does not stick out.*
This privacy is afforded with the best technology. I implore you to take a few minutes to learn about the four main technologies that Monero uses to provide privacy:
There are several other things that make Monero great! It has a smooth tail emission, dynamic blocks and fees, and an accessible Proof of Work (mining) algorithm.
*You can optionally choose a very large, unusual ringsize to make the transaction stick out. This is not recommended, and normal users who leave the ringsize at the default setting will not experience any issues. Also, it's possible for a user to manually add identifying information to the tx_extra field, which is something that a user must seriously go out of their way to do.
Now you know Monero (XMR) has the best technology. What else makes Monero (XMR) different than other cryptocurrencies?
P.S. Want a quick-start, simple your-grandma-could-do-it guide? Here's a great one!
Am I a bad person to consider using this?
No, Monero is freedom money. You can do whatever you want with it, whenever you want, where ever you want. We make it clear that you should own your wealth 100%. What you do with it, is none of our concern.
Where does the word Monero come from?
The word Monero comes from the language Esperanto. Monero means coin oand currency. The plural way of saying Monero in Esperanto and in our cryptocurrency is Moneroj.
How do I store Monero?

Is there a lightweight wallet for Monero?
Not yet, but you can use the official GUI with a remote node.
Are there any other ways to store Monero (XMR)?
Yes, there are many mobile wallets out there that allow you to store Monero (XMR). We do not recommend them, because they are not official releases of Monero. If you do decide to use other wallets, please make sure to do your research first before storing any Moneroj in the wallet. Anything used for Monero outside of official releases, will be used at your own risk. Some may be used for scamming purposes. If you still decide to take the risk; do not use them for large amounts. Also keep in mind that there is a high chance that Monero support will not be able to help you if you bump into any problems from applications outside of official releases. Why should you not use non-official wallets? Well would you buy a house and give your only key you have to the buildemanagement and wait for him/her to open the door to the house you supposedly own? No. Same goes with cryptocurrencies. You should always have possession of your private keys, and your Moneroj. Most non-official releases own your private keys, therefore you do not own the Moneroj.

A tour of the Gridcoin wallet

Hey guys, I thought I would put together an in-depth tour of the Gridcoin wallet software for all of our recent newcomers. Here I'll be outlining all the features and functions the windows GUI wallet has to offer, along with some basic RPC command usage. I'll be using the windows wallet as an example, but both linux and macOS should be rather similar. I'll be including as many pictures as I can as embedded hyperlinks.
Edit: Note that since I originally made this there has been a UI update, so your client will be different colors but all the button locations are in the same place.
This is my first post like this, so please forgive me if this appears a little scatter-brained.
This will not cover the mining setup process for pool or solo miners.
When you launch the wallet software for the first time you should be greeted with this screen.


After that prompt, you should be left sitting on the main overview tab with several fields on it.
From top to bottom:


Now onto the other tabs on the left side. Currently we're on the Overview tab, lets move down to the Send tab. This tab it pretty self-explanatory, you use it if you want to send coins, but I'll go over the fields here:
  • Pay To: Enter a valid gridcoin address to send coins too. Gridcoin addresses always start with an S or and R.
  • Label: Enter a label here and it will put that address in your "address book" under that label for later use. You can leave it blank if you don't want it in your address book.
  • Message: Enter a message here if you want it attached to your transaction.
  • Amount: How many coins you want to send.
  • Add Attachment: Leave this alone, it is broken.
  • Track Coins: This doesn't do anything.


Now down to the Receive tab. Here you should have a single address listed. If you double click on the label field, you can edit it's label.
  • New: Generate a new address.
If you click on an address, the rest of the options should be clickable.
  • Copy: Copy the selected address to your clipboard.
  • Show QR Code: Show a scan-able QR code for the selected address.
  • Sign Message: Cryptographically sign a message using the selected address.


The Transactions tab is pretty boring considering we have no transactions yet. But as you can see there are some sorting tools at the top for when you do have transactions listed.


The Address Book is where all the addresses you've labeled (that aren't yours) will show up.
  • Verify Message: Verifies a message was signed by the selected address.
The rest of the functions are similar to the functions on the Receive tab.


Onto the Voting tab. There wont be any polls because we aren't in sync yet.
  • Reload Polls: Pretty self-explanatory, I've never had to use this.
  • Load History: By default, the wallet will only display active polls. If you want to view past polls you can use this.
  • Create Poll: You can create a network-wide poll. You must have 100,000 coins as a requirement to make a poll. (Creating a poll does not consume the coins)
Here's what the Voting tab will look like once you're in sync


Now onto the context bar menus on the top.
Under File you have:
  • Backup Wallet/Config: This lets you backup your wallet configuration file just in case.
  • Export: You can export your Transactions tab or Address Book in CSV format.
  • Sign message: Does the same thing as on the Receive tab.
  • Verify message: Does the same thing as on the Address Book tab.
  • Exit: Close the wallet.
Under Settings you have:
  • Encrypt Wallet: Encrypts your wallet with a password. (we'll come back to this)
  • Change Passphrase: Allows you to change your encryption password.
  • Options: Opens the options menu. (We'll come back to this)
Under Community you have:
Under Advanced you have:
  • Advanced Configuration: Opens the Advanced Configuration menu. (Not so advanced if you ask me)
  • Neural Network: Allows you to view solo miners project statistics. It will be largely blank if you're not in sync yet.
  • FAQ: Don't touch this, It is broken.
  • Foundation: Don't touch this, It is broken.
  • Rebuild Block Chain: Starts the client syncing from 0. Don't worry, using this will not make you lose coins.
  • Download Blocks: Downloads the latest official snapshot, can help speed up syncing. The download progress tends to sit at 99.99% for a long time, don't worry, it's working.
Under Help you have:
  • Debug window: Opens the debug window. (We'll come back to this)
  • Diagnostics: Don't touch this, it is broken. This has since been fixed. You can use this to see if there is anything wrong with your setup.
  • About Gridcoin: Opens the About Dialog. This gives you your client version and other information.


Now back to the options menu under Settings > Options.
Here we have the options menu main tab:
  • Pay transaction fee: The transaction fee that will be automatically paid when you make a transaction.
  • Reserve: You can reserve an amount so that it will always be available for spending.
  • Start Gridcoin on system login: Pretty self-explanatory
  • Detach databases at shutdown: Speeds up shutdown, but causes your blockchain file to no longer be portable.
On the Network tab:
  • Map port using UPnP: Attempts to connect to nodes through UPnP.
  • Connect through SOCKS proxy: Allows you to connect through a proxy.
The window tab is pretty self-explanatory.
The Display tab is also pretty self-explanatory, with the exception of:
  • Display coin control features (experts only!): This allows you to have a great deal of control over the coins in your wallet, check this for now and I'll explain how to use it further down. Don't forget to click "Apply".


Now that all of that is out of the way. The first thing you'll want to do is encrypt your wallet. This prevents anybody with access to your computer from sending coins. This is something I would recommend everyone do.
Go to Settings > Encrypt Wallet and create a password. YOU CANNOT RECOVER YOUR COINS IF YOU FORGET YOUR PASSWORD.
Your wallet will close and you will have to start it up again. This time when it opens up, you should have a new button in the bottom left. Now if you want to stake you will have to unlock your wallet. Notice the "For staking only" box that is checked by default. If you want to send a beacon for solo mining or vote, you will need to uncheck this box.


Before we continue, Let's wait until we're in sync. Depending on your internet speeds, this could take from several hours to over a day or 2. This can be sped up by using Advanced > Download Blocks, but this can still take several hours.
This is what an in-sync client should look like. Notice the green check to the right of the Receive tab. All of these icons give you information when you hover your mouse over them.
The lock
The arrow tells you if you're staking. If you aren't staking, it will tell you why you're not staking. If you are staking it will give you an estimated staking time. Staking is a very random process and this is only an estimate, not a countdown.
The connection bars tell you how many connections to the network you have.
The check tells you if you're in sync.


Now I've said "stake" about a million times so far and haven't explained it. Gridcoin is a Proof of Stake (PoS) coin.
Unlike bitcoins Proof of Work (PoW), PoS uses little system resources, so you can use those resources for scientific work. PoS works by users "Staking" with their balance. The higher the balance, the higher the chance to create, or "stake" a block. This means you need to have a positive balance in order to stake. Theoretically, you can stake with any amount over 0.0125 coins, but in practice it's recommended to have at least 2000 coins to reliably stake.
Staking is important for solo miners, because they get paid when they stake. Pool miners don't need to stake in order to get paid however. So if you want to solo mine, you'll need to buy some coins from an exchange or start in the pool first and move to solo when you have enough coins.
In addition to Research Rewards for miners, anyone who holds coins (solo miners, pool miners, and investors) gets 1.5% interest annually on top of your coins. So it can be beneficial for pool miners to stake as well.
Here is a snippet of what a research rewards transaction looks like from my personal wallet. I have a label on that address of "Payout address" as you can see here.


At this point you'll need some coins. You can use one of our faucets like this one or this one to test coin control out.
First let me explain what a UTXO is. UTXO stands for Unspent Transaction Output. Say you have an address with 0 coins in it, and someone sends you 10 coins like I've done here. Those 10 coins are added to that address in the form of a UTXO, so we have an address with one 10 coin UTXO in it.
Now we receive another 5 coins at the same address, like so. Now we have an address with one 10 coin UTXO and one 5 coin UTXO. But how do we view how our addresses are split up into different UTXOs?
Earlier we checked the "Display coin control features" box in Settings > Options > Display. Once that's checked you'll notice there's another section in the Send tab labeled "Coin Control Features". If you click the "Inputs" button, you'll get a new window. And look, there's our 2 UTXOs.
All UTXOs try to stake separately from each other, and remember that the chance a UTXO has to stake is proportional to it's size. So in this situation, my 10 coin UTXO has twice the chance to stake as my 5 coin UTXO. Now wallets, especially ones that make a lot of transactions, can get very fragmented over time. I've fragmented my wallet a little so I can show you what I'm talking about.
How do we clean this up? We can consolidate all this into one UTXO by checking all the boxes on the left and selecting OK.
Now pay attention to the fields on the top:
  • Quantity: The total amount of UTXOs we have selected.
  • Amount: The total amount of coins we have selected.
  • Fee: How much it would cost in fees to send all those UTXOs (more UTXOs = more transaction data = more fees)
  • After Fee: Amount - Fees.
  • Bytes: How large the transaction is in bytes.
  • Priority: How your client would prioritize making a transaction with this specific set of UTXOs selected had you not used coin control.
  • Low Output: If your transaction is less than 0.01 coins (I think).
  • Change: What you will get back in change.
  • custom change address: You can set the address you get your change back at, by default it will generate a new address.
So let's fill out our transaction so we end up with 1 UTXO at the end.
In "Pay To:" Just put any address in your wallet, and for the amount put what it has listed in the "After Fee" Field. Just like this.
Notice how we get no change back.
Now click "Send", we'll be prompted to enter our passphrase and we're asked if we want to pay the fee, go ahead and click "Yes".
Now if we go back to the Overview tab we get this funky icon. If you hover your mouse over it, it says "Payment to yourself", and the -0.0002 GRC is the network transaction fee.
(Ignore the first one, that was me fragmenting my wallet)
Now if we look at the Coin Control menu, we can see that we've slimmed our wallet down from 7 UTXOs to 1.
Now why would you want to use coin control?
2 Situations:
  1. UTXOs less than 0.0125 coins cannot stake. So you can combine a lot of tiny, useless UTXOs into 1 bigger one that can stake.
  2. After a UTXO stakes, it cannot stake for another 16 hours. So if you have 1 large UTXO that is big enough to stake more than once every 16 hours, you can split it into smaller UTXOs which can allow you to stake slightly more often.
  3. By default, the wallet will always generate a new address for change, which can make your wallet get very messy if you're sending lots of transactions. Keep in mind that more UTXOs = larger transactions = more fees.
Sidenote - When you stake, you will earn all research rewards owed reguardless of which UTXO staked. However, you'll earn the 1.5% interest for that UTXO. Not your whole wallet.


A fork is when the network splits into multiple chains, with part of the network on each chain. A fork can happen when 2 blocks are staked by different clients at the same time or very close to the same time, or when your client rejects a block that should have been accepted due to a bug in the code or through some other unique circumstance.
How do I know if I'm on a fork?
Generally you can spot a fork by looking at the difficulty on your Overview tab. With current network conditions, if your difficulty is below 0.1, then you're probably on a fork.
You can confirm this by comparing your blockhash with someone elses, like a block explorer.
Go to [Help > Debug Window > Console]. This is the RPC console, we can use to do a lot of things. You can type help to get a list of commands, and you can type help [command you need help with] (without the brackets) to get information on a command. We'll be using the getblockhash [block number] command.
Type getblockhash [block number] in the console, but replace [block number] with the number listed next to the "Blocks:" field on the Overview tab.
This will spit out a crazy string of characters, this is the "blockhash" of that block.
Now head over to your favorite block explorer, I'll be using gridcoinstats. Find the block that you have the hash for, use the search bar or just find it in the list of blocks.
Now compare your hash with the one gridcoinstats gives you. Does it match?
If it matches, then you're probably good to go. If it matches but you still think you're on a fork, then you can try other block explorers, such as or
If it doesn't match, then you need to try to get off that fork.
How do I get off a fork?
  1. Just wait for an hour or two. 95% of the time your client is able to recover itself from a fork given a little time.
  2. Restart the client, wait a few minutes to see if it fixes itself. If it doesn't restart again and wait. Repeat about 4 or 5 times.
  3. Find where the fork started. Using the getblockhash command, go back some blocks and compare hashes with that on a block explorer so you can narrow down what the last block you and the block explorer had in common. Then use reorganize [the last block hash you had in common]. Note that reorganize takes a blockhash, not a block number.
  4. Use Advanced > Download Blocks.
  5. If none of this works, you can take a look at social media (reddit/steemit) and see what other people are saying.


Your configuration file depends on your operation system:
  • On Windows: %appdata%\GridcoinResearch\
  • On Linux: ~/.GridcoinResearch/
  • On MacOS: /Users/USERNAME/Library/Application/Support/GridcoinResearch/
And it should look like this.
If you open up your gridcoinresearch.conf, you'll see the default one it generated. Note that if you entered your email earlier, the first line will have your email on it instead of "investor". If you decided you want to solo mine but didn't enter your email when you first started the wallet, go ahead and put your email on the first line in place of "investor". If you're a pool miner, just leave it as "investor".
Next, it's recommended that you use the addnodes on the gridcoin wiki. So our gridcoinresearch.conf will look like this.
A useful line for solo miners is PrimaryCPID=[YOUR CPID]. Sometimes your wallet can pick up on the wrong CPID so it's good to have that in there if you're solo mining.


A listening node is a node that listens for blocks and transactions broadcasted from nodes and forwards them on to other nodes. For example, during the syncing process when you're getting your node running for the first time, you're downloading all the blocks from listening nodes. So running a listening node helps support the network.
Running a gridcoin listening node is simple. All you need to do is add listen=1 to your gridcoinresearch.conf and you need to forward port 32749 on your router.
If you don't know how to port forward, I'd suggest googling "How to port forward [your router manufacturer]".

Logs of yesterday's dev meeting

 Dev meeting?  Would say so, yes  The people are still exhausted from the payment ID meeting :)  Guess we could ping some people  vtnerd, moneromooo, hyc, gingeropolous, TheCharlatan, sarang, suraeNoether, jtgrassie  Anyone up for a meeting?  Yep I'm here  Here  o/  Perhaps we should just start and people will eventually hop in?   oof   sorry guys, I'm working on the new FFS and I forgot all about this. Got a couple of new volunteers.   This literally might be able to launch tomorrow.  I know that. It's called "flow" :)  I could run if you're out of time?   go for it dEBRUYNE   you guys are going to like this new FFS. We're like 99% done.  Hi  rehrar: someone else do the milestone thing already?  All right, jtgrassie, perhaps you'd to start w/ briefly describing your most recent PR?   oneiric, xiphon did everything   like....everything  As far as I can see, it allows the user to push his transaction over I2P, thereby masking the origin IP of the sendeuser  great  And it hooks into vtnerd's PR right?  Sure. It basically just builds on vtnerds Tor stuff.  sorry dEBRUYNE  Really not much added.  I have it running and tested.  From the perspective of the user, what needs to be configured exactly?  Nice  Assuming the PR is included in the release binaries  I'm using knacccs i2p-zero duirng testing but will of course work with any i2p setup   sorry dEBRUYNE <= Np  Looks a little like dams breaking, now that we have some dark clouds over Kovri and people take matters into their own hands ...  User needs to run i2p, expose a socks service and and inbound tunnel.  Basically same as Tor  Okay, so should be reasonable as long as we write proper documentation for it (e.g. an elaborate guide)  rbrunner, yes, knaccc credit for jumping on i2p-zero really  dEBRUYNE: documentation monero side is kindof done. i2p side is very much implementation specific.  I suppose we could write some guides for the most popular implementations?  e.g. i2p-zero aims to be zero conf, but i2pd or Kovri would be differnet.  I see, great  vtnerd___: Do you want to add anything?  could amend the current kovri guide for monero use from --exclusive-peer to the new proxy support  Now I have i2p-zero running and tested with the #5091, I plan to jump back over to helping knaccc on getting that polished.  I added support for socks proxy in the basic wallets  ^ excellent  Yes vtnerd___ I havent tested it yet but looks sweet.  So connections to `monerod` over Toi2p are possible within wallet cli and wallet rpc  Awesome  This also implies auth+encryption even if ssl is not in use (when using an onion or i2p address)  All right  moneromooo: are you here? If so, could you perhaps share what you've been working on?  I am.  I revived the SSL PR, more stuff on multi sender txes, an implementation of ArticMine's new block size algorithm.  I presume a multi sender tx works similar to multisig insofar as the senders have to exchange data before the transaction can be performed right?  Yes.  There are 2 SSL PRs. What's the diff?  Theoretically this would also allow the sender to provide an output right? Which would be kind of similar to Bitcoin's P2EP  The second one adds some things like selecting a cert by fingerprint.  Yes.  (for the first sentence)  All right, awesome  For anyone reading, this breaks the assumption of the inputs belonging to a single sender, which makes analysis more difficult  Nice side-effect.  Much work coming for the various wallets to support that  rbrunner: Anything you'd like to share in the meeting btw?  Yes, just a little info  I have started to seriously investigate what it would mean to integrate Monero into OpenBazaar  I have already talked with 2 of their devs, was very interesting  In maybe 2 or 3 weeks I intend to write a report  Too early to tell much more :)  Soon^tm I guess :)  Yep  Currently wrestling with Go debugging  whole new world  moneromooo: Has pony recently shared any insights regarding the upcoming 0.14 release btw?  No.  All right  I would love to see the tor & i2p PR's merged sooner rather than later so we can get more testing done.  ^ +1  Isn't that famous early code freeze already on the horizon?  fluffypony, luigi1111 ^  I suppose I could provide a little update regarding the GUI btw  As always, lots of bug fixes and improvements :-P  selsta has recently added a feature to support multi accounts  dsc_ has revamped the wizard and will now start working on implementing the different modes and a white theme  dsc_ is working fulltime on the GUI already?  yes  :)   dsc_ is bae  In light of the recent payment ID discussion, we've also, by default, disabled the option to add a payment ID unless the user explicitely activates the option on the settings page  rehrar ^  nice   I spoke about this yesterday at the coffee chat, this is not a good decision.  How does it handle integrated addresses? The same way?  rehrar ?   For the next many months, we are still stuck with PAyment IDs in the ecosystem. Making it harder for people to access them will make Monero suck so hard to use for the average person for many months.  i agree with rehrar   Remove the option of Payment IDs when we remove Payment IDs  rehrar: The new GUI release won't be live until probably mid march though  Which is a few weeks in advance of the scheduled protocol upgrade   Payment ID removal comes in October   right, but Payment IDs are not removed in March  Did we not have loose consensus on removing the old, unencrypted payment IDs in march?   they are removed in October  We had discussed a deprecation in March  and a ban in October   ok, then if we are going to do that, we have to commit to it and contact the exchanges like Binance that use them and get rid of them in the next few months  (of unencrypted)   Binance is huge, and if they still use them, then people will be very upset that they can't deposit or use Payment IDs easily   I'm just speaking from a UX perspective.  I thought it was unencrypted in April and possibly encrypted in October  Yes I do agree  Timeline and notes:  impossible to remove them for march, many exchanges still use them  We can defer it to the 0.15 release if needed  Well, that wasn't the impression for them log that I just read today  This was all discussed in the earlier meeting linked above   We have to force the ecosystem off of Payment IDs before we remove them from the UI, is all I'm saying  Remove != make difficult to use  ... or make them more difficult there, right?  ping sgp_   sarang, I understand, and I agreed with you during that meeting. But then I started thinking of it as a UX person, which I am.   And that huge massive problem leapt out at me  i think making them difficult to generate is a good idea but making them difficult to consume and use is a bad idea  well, maybe not a good idea, but a better idea   ^  If we defer the decision to depriciate long payment IDs to october, won't we have the same issue then?  The UI can gave an expandable payment ID field like MyMonero and we can still call it deprecated   It is foolhardy to remove an option that the ecosystem uses. So I suggest we keep the Payment ID in the UI until October when they are completely banned.   no dEBRYUNE, because they will be banned via consensus  sgp_ imo it may be a misdirection of dev resources to add that since things are proceeding in the short term rather than long term  but this is a relatively minor point  Nothing matters til exchanges change  All right   The issue is that consensus will still have them in April, and exchanges won't upgrade because they are still allowed. Thus they must still be in the UI.  endogenic these changes are already merged in the GUI to hide it like you do  ok   But when they are banned, exchanges are forced to upgrade or stop using Monero, so we can remove them safely because they won't be in use  rehrar: that's a strong assumption   sarang that they will upgrade?  yes   if they don't, then they can't use Monero  If exchanges require pid, users need a way to set a pid. Making it hard for the user in the interim is just going to be a nightmare.   we have decided to take our "stand" in October  A way that is not too hard, then  To be clear, we still intend to deprecate long encrypted payment IDs in April right? But no enforcement until October   the term "deprecated" doesn't mean much if it's still allowed, and used in popular places   yes, as far as I understand it   jtgrassie, exactly  True I suppose  dEBRUYNE: we need to be more specific when talking about deprecation   the person who suffers is the user  There are two proposals for GUI deprecation:  1. Hide it in the send screen with a simple option to expand (currently merged iirc)  2. Hide it completely in the send screen unless users enable the field in advanced settings (PR'd but not merged yet iirc)  What are the arguments for 2?   Both are poor options, but 1 is better than 2 by a long shot   Well the people who need to be made to "suffer" are the exchanges. And I don't see a way to make exchanges "suffer" other than by having their suffering customers complain to them constantly that they need to update.  ^  CLI has something similar where users need to set a manual payment ID transfer mode. Not sure if it's merged yet   the way to make the exchanges suffer is when we ban PIDs. They either upgrade or don't use Monero.  exact;y  Agree with rerahr here  have exchanges been provided with clear, practical, sufficient technical upgrade plans for supporting what they're doing with PIDs but with subaddrs?    Both are poor options, but 1 is better than 2 by a long shot <= I wouldn't call 1. a poor option. Have you actually checked how it looks?  Because it states "Payment ID" and a user has to click on the + to expand the field  endogenic: yes the email when out. Blog post coming soon, but contains the same info as the email  also the exhcnages' users are often using wallets that don't support subaddresses  ok great   as well, it should be noted that the timeline for exchanges to upgrade is September, not October when the fork is.  Which wallets are that?  Rehrar: I don't see option 1. causing any issues/confusion  i guess it doesnt matter too much if withdrawing as a personal user the main address should suffice   Because September is when the new versions will be coming out without PIDs in the UI  If there's opposition to 2, 1 is fine. We can still call it deprecated which is the optics we need anyway   exchange users are often just using other exchanges lol. No wallets involved.   dsc_ dEBRUYNE, ok, I trust you guys here then  rbrunner: i was thinking mymonero last i heard  Ok  pigeons: rbrunner yes receiving on subaddresses won't be supported yet  sending to them has been possible though  and yes as learnandlurkin says often they withdraw to other systems like exhcnages that also dont yet support subaddresses  I really can't come up with any good argument for 2. right now  endogenic: seems not much of an issue then. Exchanges will typically support withdrawals to both subaddresses and plain addresses (especially if we are going to force them to use subaddresses)  For deposits, MyMonero works properly if the user sends to a subaddress  Actually the second solution was already merged:  Maybe not enough eyes watching :)   The important thing is to have done something to justify having a big "DEPRECATED IN APRIL" stamp on PIDs to spook exchanges in the interim  This was for solution 1:   The Monero Community Workgroup will start making noise everywhere we can to exchanges, and everywhere else that will listen. Try to get on those garbage news sites also.   So everyone knows that deprecated in April, and banned in September  Hey, for solution 1, write "Payment ID (optional, deprecated)" or similar there  rbrunner: noted  rehrar: probably wait until the blog post, but it should only be a few days   Maybe a Reddit sticky post would be useful?   With the blog post   If people are over freaking out about the hashrate  or terabyte blockchain :)  sigh  Any questions for the MRL side?  Is someone checking ArticMine's block size changes for weird behaviour in some cases etc ?  How would such testing work? Private blockchain?  I'm waiting on cost information from ArticMine to complete the model  Or just simulations?  Also, smooth suggested a mean rather than median for the 100000 block op. It would indeed be much nicer if it doesn't make the change worse.  You mean computationally or what?  Nicer ? Yes.  no sorting needed for mean  I'll add a separate sim for that  Well, just nicer. Forger the much.  Forger the Much sounds like the formal name of a Lord of the Rings character  :)  To close the payment ID discussion, in essence, we agree that we shouldn't make it difficult for the user to add a payment ID right (until 0.15 is released)  ?  I don't. I did make it harder.  In the CLI, somewhat other story, I would say  than the GUI  People there are used to juggle with options and CL parameters  rehrar: I recommend opening another issue to reverse 1866 and we can gather feedback on it there  Sounds good, to me at least   Dudes, if I do a Jitsi stream right now to show the new FFS in action, would you guys be interested in watching it?  I'd watch it, if the meeting is formally done  sure  yeah, can I start one and record it?   I'll give it in like fifteen minutes   I'll let you all know, stand by  I have a question on tx_extra if no one else has anything to talk about  People have said you can put arbitrary data in there in whatever format you want as long as you're willing to pay for it. However, do you need to mine the transaction for it to be included? I didn't think nodes would block transactions with arbitrary tx_extra data  It'll be in nodes' txpool when you relay it. A wallet could see it before it's mined.  moneromooo: will it be mined though?  by others  Is it valid ?  assume it's otherwise valid  Does it have a high enough fee ?  assume it does yes  I ran into conflicting information here:  Then it will probably be mined.  I once had the idea to put "my" MMS messages in there, looked at the code, and found no hard blocks for tx_extra data  That answer looks incorrect.  It is incorrect  If it will be mined, then that meets my assumption. There seems to be some misconception that people will not mine transactions with arbitrary tx_extra. I can add some comments there  And please don't spam it, and don't put fingerprintable stuff in it. It's meant to be here for *useful* stuff that's "uniform" enough.  It will be mined, whether a wallet *displays* the tx_extra is a different question.  I don't think any wallet currently displays that  it soes if its a pid  I think  Yeah, of course :)  Great, that answers my question

The early smart contracts of Era Swap Ecosystem like TimeAlly, Newly Released Tokens, Assurance, BetDeEx of Era Swap Ecosystem, are deployed on Ethereum mainnet. These smart contracts are finance-oriented (DeFi), i.e. most of the transactions are about spending or earning of Era Swap tokens which made paying the gas fees in Ether somewhat intuitive to the user (withdrawal charges in bank, paying tax while purchasing burgers) but transactions that are not token oriented like adding a nominee or appointee voting also needs Ether to be charged. As more Era Swap Token Utility platform ideas kept appending to the Era Swap Main Whitepaper, more non-financial transaction situations arise like updating status, sending a message, resolving a dispute and so on. Paying extensively for such actions all day and waiting for the transaction to be included in a block and then waiting for enough block confirmations due to potential chain re-organizations is counter-intuitive to existing free solutions like Facebook, Gmail. This is the main barrier that is stopping Web 3.0 from coming to the mainstream.
As alternatives to Ethereum, there are few other smart contract development platforms that propose their own separate blockchain that features for higher transaction throughput, but they compromise on decentralization for improving transaction speeds. Moreover, the ecosystem tools are most advancing in Ethereum than any other platform due to the massive developer community.
With Era Swap Network, the team aims to achieve scalability, speed and low-cost transactions for Era Swap Ecosystem (which is currently not feasible on Ethereum mainnet), without compromising much on trustless asset security for Era Swap Community users.

Introduction to Era Swap Network

Era Swap Network (ESN) aims to solve the above-mentioned problems faced by Era Swap Ecosystem users by building a side-blockchain on top of Ethereum blockchain using the Plasma Framework.
Era Swap Network leverages the Decentralisation and Security of Ethereum and the Scalability achieved in the side-chain, this solves the distributed blockchain trilema. In most of the other blockchains, blocks are a collection of transactions and all the transactions in one block are mined by a miner in one step. Era Swap Network will consist of Bunches of Blocks of Era Swap Ecosystem Transactions.


Layer 2

Scalable and Secure

A miner mines all the blocks in a bunch consequently and will commit the bunch-root to the ESN Plasma Smart Contract on Ethereum mainnet.

Development Overview
Initially, we will start with a simple Proof-of-Authority (PoA) based consensus of EVM to start the development and testing of Era Swap Ecosystem Smart Contracts as quickly as possible on the test-net. We will call this as an alpha-release of ESN test-net and only internal developers will work with this for developing smart contracts for Era Swap Ecosystem. User’s funds in a Plasma implementation with a simple consensus like PoA are still secured as already committed bunch-roots cannot be reversed.
Eventually, we want to arrive on a more control-decentralized consensus algorithm like Proof-of-Stake (PoS) probably, so that even if the chain operator shuts down their services, a single Era Swap Ecosystem user somewhere in the world can keep the ecosystem alive by running software on their system and similarly more people can join to decentralize the control further. In this PoS version, we will modify the Parity Ethereum client in such a way, that at least 50% of transaction fees collected will go to the Luck Pool of NRT Smart Contract on Ethereum mainnet and rest can be kept by miner of the blocks/bunch of blocks if they wish. After achieving such an implementation, we will release this as a beta version to the community for testing the software on their computers with Kovan ERC20 Era Swaps (Ethereum test-net).

Era Swap Decentralised Ecosystem
Following platforms are to be integrated:
  1. Era Swap Token Contract (adapted ERC20 on Ethereum) The original asset will lie on Ethereum to avoid loss due to any kind of failure in ESN.
  2. Plasma Manager Contract (on Ethereum) To store ESN bunch headers on Ethereum.
  3. Reverse Plasma Manager Contract (on ESN) Bridge to convert ES to ES native and ES native to ES. User deposits ES on Mainnet Plasma, gives proof on ESN and gets ES native credited to their account in a decentralised way.
  4. NRT Manager Contract (on Ethereum or on ESN) If it is possible to send ES from an ESN contract to luck pool of NRT Manager Contract on Ethereum, then it’s ok otherwise, NRT Manager will need to be deployed on ESN for ability to add ES to luck pool.
  5. Era Swap Wallet (React Native App for managing ESs and ES natives) Secure wallet to store multiple private keys in it, mainly for managing ES and ES native, sending ES or ES native, also for quick and easy BuzCafe payments.
  6. TimeAlly (on Ethereum or on ESN) On whichever chain NRT Manager is deployed, TimeAlly would be deployed on the same chain.
  7. Assurance (on Ethereum or on ESN) On whichever chain NRT Manager is deployed, TimeAlly would be deployed on the same chain.
  8. DaySwappers (on ESN) KYC manager for platform. For easily distributing rewards to tree referees.
  9. TimeSwappers (on ESN) Freelance market place with decentralised dispute management.
  10. SwappersWall (on ESN) Decentralised social networking with power tokens.
  11. BuzCafe (on ESN) Listing of shops and finding shops easily and quick payment.
  12. BetDeEx (on ESN) Decentralised Prediction proposals, prediction and results.
  13. DateSwappers (on ESN) Meeting ensured using cryptography.
  14. ComputeEx (on Ethereum / centralised way) Exchange assets.
  15. Era Swap Academy (on ESN / centralised way) Learn. Loop. Leap. How to implement ES Academy is not clear. One idea is if content is constantly being modified, then subscription expired people will only have the hash of old content while new content hash is only available to people who have done Dayswapper KYC and paid for the course. Dayswapper KYC is required because this way people won’t share their private keys to someone else.
  16. Value of Farmers (tbd) The exchange of farming commodities produced by farmers in VoF can be deposited to warehouses where the depositors will get ERC721 equivalent tokens for their commodities (based on unique tagging).
  17. DeGameStation (on ESN) Decentralised Gaming Station. Games in which players take turns can be written in Smart Contract. Games like Chess, Poker, 3 Patti can be developed. Users can come to DeGameStation and join an open game or start a new game and wait for other players to join.

Alpha-release Development Plan
  1. Deploying Parity Node customized according to Era Swap Whitepaper with PoA consensus.
  2. Setting up Plasma Smart Contracts.
  3. Creating a bridge for ERC20 Swap from Ethereum test-net to ESN alpha test-net.

Alpha Version
Era Swap Network Version 1 : Specification
The Version 1 release of ESN plans to fulfill the requirements for political decentralisation and transparency in dApps of Era Swap Ecosystem using Blockchain Technology. After acquiring sufficient number of users, a version 2 construction of ESN will be feasible to enable administrative decentralization, such that the Era Swap Ecosystem will be run and managed by the Era Swap Community and will no longer require the operator to support for it's functioning.
Era Swap Network (ESN) Version 1 will be a separate EVM-compatible sidechain attached to Ethereum blockchain as it’s parent chain. ESN will achieve security through Plasma Framework along with Proof-of-Authority consensus for faster finality. The idea behind plasma framework is to avoid high transaction fees and high transaction confirmation times on Ethereum mainnet by instead doing all the ecosystem transactions off-chain and only post a small information to an Ethereum Smart Contract which would represent hash of plenty of ecosystem transactions. Also, to feature movement of Era Swap Tokens from Ethereum blockchain to ESN using cryptographic proof, reverse plasma of Ethereum on ESN will be implemented.
Also, submitting hash of each ESN blocks to ESN Plasma Smart Contract on Ethereum would force ESN to have a block time equal to or more than Ethereum’s 15 second time as well as it would be very much costly for operator to post lot of hashes to an Ethereum Smart Contract. This is why, merkle root of hashes of bunch of blocks would instead be submitted to ESN Plasma Smart Contact on Ethereum.
Actors involved in the ESN:
  1. Block Producer Nodes Lesser the number of nodes, quicker is the block propagation between block producers which can help quick ecosystem transactions. We find that 7 block producers hosted on different could hosting companies and locations reduces the risk of single point of failure of Era Swap Ecosystem and facilitates 100% uptime of dApps. Block Producer Nodes will also be responsible to post the small information to the Blockchain.
  2. Block Listener Nodes Rest of the nodes will be Block Listeners which will sync new blocks produced by the block producer nodes. Plenty of public block listener nodes would be setup in various regions around the world for shorter ping time to the users of Era Swap Ecosystem. Users would submit their Era Swap Ecosystem transactions to one of these public nodes, which would relay them to rest of the Era Swap Network eventually to the block producer nodes which would finalize a new block including the user transaction.
  3. Bunch Committers This will be an instance in the block producers which will watch for new blocks confirmed on ESN and will calculate bunch merkle roots and will submit it to ESN Plasma Smart Contract. This instance will also post hash of new Ethereum blocks to ESN (after about 10 confirmations) for moving assets between both the blockchain.
  4. Users These will be integrating with dApps which would be connected to some public ESN nodes or they can install a block listner node themselves. They can sign and send transactions to the node which they are connected to and then that node will relay their transactions to block producer nodes who would finalise a block including their transaction.

Bunch Structure

A Bunch Structure in Smart Contract will consist of the following:
• Start Block Number: It is the number of first ESN block in the bunch.
• Bunch Depth: It is Merkle Tree depth of blocks in the bunch. For e.g. If bunch depth is 3, there would be 8 blocks in the bunch and if bunch depth is 10, there would be 1024 blocks in the bunch. Bunch depth of Bunches on ESN Plasma Contract is designed to be variable. During the initial phases of ESN, it would be high, for e.g. 15, to avoid ether expenditure and would be decreased in due course of time.
• Transactions Mega Root: This value is the merkle root of all the transaction roots in the bunch. This is used by Smart Contract to verify that a transaction was sent on the chain.
• Receipts Mega Root: This value is the merkle root of all the receipt roots in the bunch. This is used to verify that the transaction execution was successful.
• Timestamp: This value is the time when the bunch proposal was submitted to the smart contract. After submission, there is a challenge period before it is finalised.

Converting ES-ERC20 to ERC-NA and BACK

On Ethereum Blockchain, the first class cryptocurrency is ETH and rest other tokens managed by smart contracts are second class. On ESN, there is an advancement to have Era Swaps as the first class cryptocurrency. This cryptocurrency will feature better user experience and to differentiate it from the classic ERC20 Era Swaps, it will be called as Era Swap Natives (ES-Na). According to the Era Swap Whitepaper, maximum 9.1 Million ES will exist which will be slowly released in circulation every month.
Era Swaps will exist as ES-ERC20 as well as in form of ES-Na. One of these can be exchanged for the other at 1:1 ratio.
Following is how user will convert ES-ERC20 to ES-Na:
  1. User will give allowance to a Deposit Smart Contract, and following that call deposit method to deposit tokens to the contract.
  2. On transaction confirmation, user will paste the transaction hash on a portal which will generate a Proof of Deposit string for the user. This string is generated by fetching all the transactions in the Ethereum Block and generating a Transaction Patricia Merkle Proof to prove that user’s transaction was indeed included in the block and the Receipts Patricia Merkle Proof to confirm that the user’s transaction was successful.
  3. Using the same portal, user will submit the generated proofs to a Smart Contract on ESN, which would release funds to user. Though, user will have to wait for the Etheruem block roots to be posted to ESN after waiting for confirmations which would take about 3 minutes. Once, it’s done user’s proofs will be accepted and will receive exact amount of ES- Na on ESN.
Following is how user will convert ES-Na to ES-ERC20:
  1. ES-Na being first class cryptocurrency, user will simply send ES-Na to a contract.
  2. User will paste the transaction hash on a portal which will generate a Proof of Deposit for the user. Again ES-Na being first class cryptocurrency, Transaction Patricia Merkle Proof is enough to prove that user’s transaction was indeed included in the block. Another thing which will be generated is the block inclusion proof in the bunch.
  3. User will have to wait for the bunch confirmation to the Plasma Smart Contract and once it’s done, user can send the proof to the Plasma Smart Contract to receive ES-ERC20.


Since the blocks are produced and transactions are validated by few block producers, it exposes a possibility for fraud by controlling the block producer nodes. Because ESN is based on the Plasma Model, when failure of sidechain occurs or the chain halts, users can hard exit their funds directly from the Plasma Smart Contract on Ethereum by giving a Proof of Holdings.

HOld ES Tokens Swapping with New ES Tokens

The old ES Tokens will be valueless as those tokens will not be accepted in ESN because of NRT (New Released Tokens) and TimeAlly contracts on mainnet which is causing high gas to users, hence reducing interactions. Also, there was an event of theft of Era Swap Tokens and after consensus from majority of holders of Era Swap Tokens; it was decided to create a new contract to reverse the theft to secure the value of Era Swap Tokens of the community. Below is the strategy for swapping tokens:
TimeAlly and TSGAP: Majority of Era Swap Community have participated in TimeAlly Smart Contract in which their tokens are locked for certain period of time until which they cannot move them. Such holders will automatically receive TimeAlly staking of specific durations from the operator during initialization of ESN.
Liquid Tokens: Holders of Liquid Era Swap Tokens have to transfer the old tokens to a specified Ethereum wallet address managed by team. Following that, team will audit the token source of the holder (to eliminate exchange of stolen tokens) and send new tokens back to the wallet address.

Post-Genesis Tokens Return Program

Primary asset holding of Era Swap tokens will exist on Ethereum blockchain as an ERC20 compatible standard due to the highly decentralised nature of the blockchain. Similar to how users deposit tokens to an cryptocurrency exchange for trading and then withdraw the tokens back, users will deposit tokens to ESN Contract to enter Era Swap Ecosystem and they can withdraw it back from ESN Contract for exiting from ecosystem network. The design of the token system will be such that, it will be compatible with the future shift (modification or migration of ESN version 1) to ESN version 2, in which an entirely new blockchain setup might be required.
To manage liquidity, following genesis structure will be followed:

Holder ES-ERC20 ES-Na
Team Wallet 1.17 billion (Circulating Supply) 0
Locked in Smart Contract 7.93 billion (pending NRT releases) 9.1 billion
Though it looks like there are 9.1 * 2 = 18.2 Billion ES, but the cryptographic design secures that at any point in time at least a total of 9.1 billion ES (ES-ERC20 + ES-Na) will be locked. To unlock ES-Na on ESN, an equal amount of ES-ERC20 has to be locked on Ethereum and vice-versa.
9.1 billion ES-ERC20 will be issued by ERC20 smart contract on Ethereum Blockchain, out of which the entire circulating supply (including liquid and TimeAlly holdings) of old ES will be received to a team wallet.
TimeAlly holdings of all users will be converted to ES-Na and distributed on ESN TimeAlly Smart Contract by team to the TimeAlly holders on their same wallet address.
Liquid user holdings will be sent back to the users to the wallet address from which they send back old ES tokens (because some old ES are deposited on exchange wallet address).
ES-Na will be issued in the genesis block to an ESN Manager Smart Contract address. It will manage all the deposits and withdrawals as well as NRT releases.

Attack Vectors

Following are identified risks to be taken care of during the development of ESN:
Network Spamming: Attackers can purchase ES from the exchange and make a lot of transactions between two accounts. This is solved by involving gas fees. A setting of 200 nanoES minimum gas price will be set, which can be changed as per convenience.
DDoS: Attackers can query public nodes for computationally heavy output data. This will overload the public node with requests and genuine requests might get delayed. Block producers RPC is private, so they will continue to produce blocks. To manage user’s denial of service, the provider in dApps needs to be designed in such a way such that many public nodes will be queried simple information (let’s say latest block number) and the one which response quickly to user will be selected.
AWS is down: To minimize this issue due to cloud providers down, there will be enough nodes on multiple cloud providers to ensure at least one block producer is alive.
User deposit double spending: User deposits ES on Ethereum, gets ES-Na on ESN. Then the issue happens that there are re-org on ETH mainnet and the user’s transaction is reversed. Since ETH is not a fixed chain and as per PoW 51% attack can change the blocks. As Ethereum is now enough mature and by statistics forked blocks are at most of height 2. So it is safe to consider 15 confirmations.
Exit Game while smooth functioning: User starts a hard exit directly from Plasma Smart Contract on Ethereum, then spends his funds from the plasma chain too. To counter this, the exit game will be disabled, only when ESN halts, i.e. fails to submit block header within the time the exit game starts. This is because it is difficult to mark user’s funds as spent on ESN.
Vulnerability in Ecosystem Smart Contracts: Using traditional methods to deploy smart contracts results in a situation where if a bug is found later, it is not possible to change the code. Using a proxy construction for every ecosystem smart contract solves this problem, and changing a proxy can be given to a small committee in which 66% of votes are required, this is to prevent a malicious change of code due to compromising of a single account or similar scenario.
ChainID replay attacks: Using old and traditional ways to interact with dApps can cause loss to users, hence every dApp will be audited for the same.


Era Swap Network is an EVM-compatible sidechain attached to the Ethereum blockchain through Plasma Framework. This allows off-chain processing of Era Swap Ecosystem transactions and posting only the hash of the bunch to Ethereum. This greatly reduces the high network fee and confirmation time issues faced by the current Era Swap Ecosystem DApps deployed on Ethereum. Also, having a separate EVM-compatible blockchain tailored to Era Swap Ecosystem improves the user experience to a higher extent. Since by design, Plasma Framework makes the Era Swap Network as secure as the Ethereum Network, user's funds on the network would be secure as well.
We believe Era Swap Network will help scale dApps of Era Swap Ecosystem to onboard the increasing numbers of users.

Bitcoin uses peer-to-peer technology to operate with no central authority or banks; managing transactions and the issuing of bitcoins is carried out collectively by the network. Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part . The mining pool has the lowest share reject rate (0.15%) we've ever seen. Other pools have over 0.30% rejected shares. Furthermore, the pool has a super responsive and reliable support team. Slush Pool is the 1st mining pool with more than 1.2M BTC mined since 2010. Explore features such as advanced payouts, monitoring and more. An example of such devices are ASICminer’s Erupter Blade and Erupter Cube Bitcoin ASICs – these devices have a built-in miner software, however it uses the older getwork protocol and you would need to use a local stratum proxy in order to be able to set these devices to mine on a stratum-based BTC mining pool.
