Features

Optimized pool server

• TCP (stratum-like) protocol for server-push based jobs
  • Compared to old HTTP protocol, this has a higher hash rate, lower network/CPU server load, lower orphan block percent, and less error prone
• Support for Cryptonight (Original, Monero v7, Stellite v7), Cryptonight Light (Original, Aeon v7, IPBC) and Cryptonight Heavy (Sumokoin) algorithms.
• IP banning to prevent low-diff share attacks
• Socket flooding detection
• Share trust algorithm to reduce share validation hashing CPU load
• Clustering for vertical scaling
• Ability to configure multiple ports - each with their own difficulty
• Miner login (wallet address) validation
• Workers identification (specify worker name as the password)
• Variable difficulty / share limiter
• Set fixed difficulty on miner client by passing "address" param with "+[difficulty]" postfix
• Modular components for horizontal scaling (pool server, database, stats/API, payment processing, front-end)
• SSL support for both pool and API servers

• Universal blocks and transactions explorer based on chainradar.com

Smart payment processing

• Splintered transactions to deal with max transaction size
• Minimum payment threshold before balance will be paid out
• Minimum denomination for truncating payment amount precision to reduce size/complexity of block transactions
• Prevent "transaction is too big" error with "payments.maxTransactionAmount" option
• Option to enable dynamic transfer fee based on number of payees per transaction and option to have miner pay transfer fee instead of pool owner (applied to dynamic fee only)
• Control transactions priority with config.payments.priority (default: 0).

Usage

Requirements

• Coin daemon(s) (find the coin's repo and build latest version from source)
  • List of Cryptonote coins

• Node.js v11.0+

  • For Ubuntu:

    curl -sL https://deb.nodesource.com/setup_11.x | sudo -E bash
    sudo apt-get install -y nodejs
    

  • Or use NVM(https://github.com/creationix/nvm) for debian/ubuntu.

• Redis key-value store v2.6+

  • For Ubuntu:

    sudo add-apt-repository ppa:chris-lea/redis-server
    sudo apt-get update
    sudo apt-get install redis-server
    

    Dont forget to tune redis-server:

    echo never > /sys/kernel/mm/transparent_hugepage/enabled
    echo 1024 > /proc/sys/net/core/somaxconn
    

    Add this lines to your /etc/rc.local and make it executable

    chmod +x /etc/rc.local
    

• libssl required for the node-multi-hashing module

  • For Ubuntu:

    sudo apt-get install libssl-dev

• Boost is required for the cryptoforknote-util module

  • For Ubuntu:

    sudo apt-get install libboost-all-dev

Seriously

Those are legitimate requirements. If you use old versions of Node.js or Redis that may come with your system package manager then you will have problems. Follow the linked instructions to get the last stable versions.

Redis warning: It'sa good idea to learn about and understand software that you are using - a good place to start with redis is data persistence.

Do not run the pool as root : create a new user without ssh access to avoid security issues :

bash
sudo adduser --disabled-password --disabled-login your-user

sudo su - your-user

1) Downloading & Installing

Clone the repository and run

npm update

git clone https://github.com/dvandal/cryptonote-nodejs-pool.git pool
cd pool

npm update

2) Configuration

Copy the

config_examples/COIN.json

3) Start the pool

node init.js

The file

config.json

-config=file

node init.js -config=config_backup.json

This software contains four distinct modules: *

pool

api

unlocker

payments

chartsDataCollector

telegramBot

By default, running the

init.js

-module=name

node init.js -module=api

Example screenshot of running the pool in single module mode with tmux.

To keep your pool up, on operating system with systemd, you can create add your pool software as a service.
Use this example to create the systemd service

/lib/systemd/system/cryptonote-nodejs-pool.service

sudo systemctl enable cryptonote-nodejs-pool.service
sudo systemctl start cryptonote-nodejs-pool.service

4) Host the front-end

Simply host the contents of the

website_example

Edit the variables in the

website_example/config.js

/* Must point to the API setup in your config.json file. */
var api = "http://poolhost:8117";

/* Pool server host to instruct your miners to point to (override daemon setting if set) */
var poolHost = "poolhost.com";
/* Number of coin decimals places (override daemon setting if set) */
"coinDecimalPlaces": 4,
/* Contact email address. */
var email = "[email protected]";
/* Pool Telegram URL. */
var telegram = "https://t.me/YourPool";
/* Pool Discord URL */
var discord = "https://discordapp.com/invite/YourPool";
/*Pool Facebook URL */
var facebook = "https://www.facebook.com/
5) Customize your website

The following files are included so that you can customize your pool website without having to make significant changes
to 
index.html
 or other front-end files thus reducing the difficulty of merging updates with your own changes:
* 
custom.css
 for creating your own pool style
* 
custom.js
 for changing the functionality of your pool website

Then simply serve the files via nginx, Apache, Google Drive, or anything that can host static content.

SSL

You can configure the API to be accessible via SSL using various methods. Find an example for nginx below:


Using SSL api in 
config.json
:


By using this you will need to update your 
api
 variable in the 
website_example/config.js
. For example:

var api = "https://poolhost:8119";


Inside your SSL Listener, add the following:

location ~ ^/api/(.*) {
    proxy_pass http://127.0.0.1:8117/$1$is_args$args;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

By adding this you will need to update your 
api
 variable in the 
website_example/config.js
 to include the /api. For example:

var api = "http://poolhost/api";

You no longer need to include the port in the variable because of the proxy connection.


Using his own subdomain, for example 
api.poolhost.com
:

server {
    server_name api.poolhost.com
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

ssl_certificate /your/ssl/certificate;
ssl_certificate_key /your/ssl/certificate_key;

location / {
    more_set_headers 'Access-Control-Allow-Origin: *';
    proxy_pass http://127.0.01:8117;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_cache_bypass $http_upgrade;
}
}

By adding this you will need to update your 
api
 variable in the 
website_example/config.js
. For example:

var api = "//api.poolhost.com";

You no longer need to include the port in the variable because of the proxy connection.

Upgrading

When updating to the latest code its important to not only 
git pull
 the latest from this repo, but to also update
the Node.js modules, and any config files that may have been changed.
* Inside your pool directory (where the init.js script is) do 
git pull
 to get the latest code.
* Remove the dependencies by deleting the 
node_modules
 directory with 
rm -r node_modules
.
* Run 
npm update
 to force updating/reinstalling of the dependencies.
* Compare your 
config.json
 to the latest example ones in this repo or the ones in the setup instructions where each config field is explained. You may need to modify or add any new changes.

JSON-RPC Commands from CLI

Documentation for JSON-RPC commands can be found here:
* Daemon https://wiki.bytecoin.org/wiki/JSONRPCAPI
* Wallet https://wiki.bytecoin.org/wiki/WalletJSONRPC_API

Curl can be used to use the JSON-RPC commands from command-line. Here is an example of calling

Monitoring Your Pool


To inspect and make changes to redis I suggest using redis-commander

To monitor server load for CPU, Network, IO, etc - I suggest using Netdata

To keep your pool node script running in background, logging to file, and automatically restarting if it crashes - I suggest using forever or PM2
