This pool is being further developed to provide an easy to use pool for Ethereum Classic miners. This software is functional however an optimised release of the pool is expected soon. Testing and bug submissions are welcome!
- Support for HTTP and Stratum mining
- Detailed block stats with luck percentage and full reward
- Failover geth instances: geth high availability built in
- Separate stats for workers: can highlight timed-out workers so miners can perform maintenance of rigs
- JSON-API for stats
- New vue based UI
- Supports Ethereum Classic, Mordor, Ethereum, Ropsten, ubiq
Dependencies:
- go >= 1.19
- core-geth
- redis-server >= 2.8.0
- nodejs >= 4 LTS
- nginx
sudo apt-get update && apt-get upgrade
sudo apt-get install golang
sudo apt-get install rsync
sudo apt-get install git
sudo apt-get install ipset
sudo ipset create blacklist hash:ip
sudo apt-get install npm

It is recommended to bind your DB address on 127.0.0.1 or on internal ip. Also, please set up the password for advanced security!!!
sudo apt-get install nginx

Now install node.js. *Note the command name changes in ubuntu, nodejs instead of node. This is to avoid a name conflict with a package called node in ubuntu.
sudo apt-get install -y nodejs
Install bower. NOTE: Used by https://github.com/adiwg/mdEditor
npm WARN deprecated bower@1.8.2: ...psst! Your project can stop working at any moment because its dependencies can change. Prevent this by migrating to Yarn: https://bower.io/blog/2017/how-to-migrate-away-from-bower/
/usr/bin/bower -> /usr/lib/node_modules/bower/bin/bower
YOU HAVE BEEN WARNED
sudo npm install -g bower
I highly recommend to use Ubuntu 20.04 LTS.
- First install: sudo apt-get install build-essential
- install sudo apt-get install make
- install sudo apt-get install git
- install core-geth.
Run console

geth account new --datadir /home/pool/classic/.ethereum/
If you use Ubuntu, it is easier to control services by using serviced.
sudo nano /etc/systemd/system/geth.service
Copy the following example
[Unit]
Description=geth
After=network-online.target
[Service]
ExecStart=/home/pool/core-geth/build/bin/geth --miner.threads=1 --datadir /home/pool/classic/.ethereum/ --syncmode "snap" --http --http.api eth,net,web3,txpool,miner --miner.etherbase=0x95f296f317E8E3AFb3DEf009173E77cCe00B5aeC --mine --cache=8000 --maxpeers 100 --password="/home/pool/.pw" --allow-insecure-unlock --http.port "8545" --nat "any" --unlock 0x95f296f317E8E3AFb3DEf009173E77cCe00B5aeC --miner.extradata ys --classic --snapshot=false --port 30305
User=pool
Restart=always
RestartSec=3
[Install]
WantedBy=multi-user.target
Then run core-geth by the following commands
$ sudo systemctl enable geth
$ sudo systemctl start geth
If you want to debug the node command
$ sudo systemctl status geth
Firewall should be opened to operate this service. Whether Ubuntu firewall is basically opened or not, the firewall should be opened based on your situation. You can open firewall by opening 80,443,8008,30305.
Clone & compile:
git clone https://github.com/yuriy0803/open-etc-pool-friends.git
cd open-etc-pool-friends
go build
nano ~/open-etc-pool-friends/www/config/environment.js
Make some modifications in these settings.
ApiUrl: '//your-pool-domain/',
HttpHost: 'http://your-pool-domain',
StratumHost: 'your-pool-domain',
PoolFee: '1%',
The frontend is a single-page Ember.js application that polls the pool API to render miner stats.
./open-etc-pool-friends api.json
Install nodejs. I suggest using LTS version >= 4.x from https://github.com/nodesource/distributions or from your Linux distribution or simply install nodejs on Ubuntu Xenial 16.04.
NOTE: at this point keep your nodejs version <= 19.x.
The frontend is a single-page Ember.js application that polls the pool API to render miner stats.
cd www
Change ApiUrl: '//example.net/' in www/config/environment.js to match your domain name. Also don't forget to adjust other options.
Install deps
sudo npm install -g ember-cli@2.18
sudo npm install -g bower
sudo chown -R $USER:$GROUP ~/.npm
sudo chown -R $USER:$GROUP ~/.config
npm install
bower install
ember install ember-truth-helpers
npm install jdenticon@2.1.0
Build.
chmod 755 build.sh
./build.sh
It is required to run pool by serviced. If it is not, the terminal could be stopped, and pool doesn’t work.
sudo nano /etc/systemd/system/api.service
Copy the following example
[Unit]
Description=api
After=network-online.target
[Service]
ExecStart=/home/pool/open-etc-pool-friends/open-etc-pool-friends /home/pool/open-etc-pool-friends/api.json
User=pool
Restart=always
RestartSec=3
[Install]
WantedBy=multi-user.target
Then run api by the following commands
sudo systemctl enable api
sudo systemctl start api
If you want to debug the node command
sudo systemctl status api
As you can see above, the frontend of the pool homepage is created. Then, move to the directory, www, which services the file.
Set up nginx.
sudo nano /etc/nginx/sites-available/default
Modify based on configuration file.
# Default server configuration
# nginx example
upstream api {
server 127.0.0.1:8080;
}
server {
listen 80 default_server;
listen [::]:80 default_server;
root /var/www/etc2pool;
# Add index.php to the list if you are using PHP
index index.html index.htm index.nginx-debian.html;
server_name _;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
}
location /api {
proxy_pass http://127.0.0.1:8080;
}
}
After setting nginx is completed, run the command below.
sudo service nginx restart
Status all.
sudo journalctl -f
You can customize the layout using built-in web server with live reload:
ember server --port 8082 --environment development
Don't use built-in web server in production.
Check out www/app/templates directory and edit these templates
in order to customise the frontend.
Configuration is actually simple, just read it twice and think twice before changing defaults.
Don't copy config directly from this manual. Use the example config from the package, otherwise you will get errors on start because of JSON comments.

}If you are distributing your pool deployment to several servers or processes, create several configs and disable unneeded modules on each server. (Advanced users)
I recommend this deployment strategy:
- Mining instance - 1x (it depends, you can run one node for EU, one for US, one for Asia)
- Unlocker and payouts instance - 1x each (strict!)
- API instance - 1x
- Unlocking and payouts are sequential, 1st tx go, 2nd waiting for 1st to confirm and so on. You can disable that in code. Carefully read
docs/PAYOUTS.md. - Also, keep in mind that unlocking and payouts will halt in case of backend or node RPC errors. In that case check everything and restart.
- You must restart module if you see errors with the word suspended.
- Don't run payouts and unlocker modules as part of mining node. Create separate configs for both, launch independently and make sure you have a single instance of each module running.
- If
poolFeeAddressis not specified all pool profit will remain on coinbase address. If it specified, make sure to periodically send some dust back required for payments.
To use this pool on the mordor testnet two settings require changing to "mordor"
network in your config.json (this sets backend (validation,unlocker) to mordor paramaters) APP.Network in your www/config/environment.js (this sets the frontend to mordor paramaters) rerun ./build.sh
First, install the Certbot's Nginx package with apt-get
sudo apt-get update
sudo apt-get install python3-certbot-nginx
And then open your nginx setting file, make sure the server name is configured!
sudo nano /etc/nginx/sites-available/default
. . .
server_name <your-pool-domain>;
. . .
Change the _ to your pool domain, and now you can obtain your auto-renewaled ssl certificate for free!
sudo certbot --nginx -d <your-pool-domain>
Now you can access your pool's frontend via https! Share your pool link!
