cryptonote-nodejs-pool

High performance Node.js (with native C addons) mining pool for CryptoNote based coins. Comes with lightweight example front-end script which uses the pool's AJAX API. Support for Cryptonight (Original, Monero v7, Stellite v7), Cryptonight Light (Original, Aeon v7, IPBC) and Cryptonight Heavy (Sumokoin) algorithms.

Table of Contents

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
  • RBPPS (PROP) payment system

Live statistics API

  • Currency network/block difficulty
  • Current block height
  • Network hashrate
  • Pool hashrate
  • Each miners' individual stats (hashrate, shares submitted, pending balance, total paid, payout estimate, etc)
  • Blocks found (pending, confirmed, and orphaned)
  • Historic charts of pool's hashrate, miners count and coin difficulty
  • Historic charts of users's hashrate and payments

Mined blocks explorer

  • Mined blocks table with block status (pending, confirmed, and orphaned)
  • Blocks luck (shares/difficulty) statistics
  • 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).
  • Set payment ID on miner client when using "[address].[paymentID]" login
  • Integrated payment ID addresses support for Exchanges

Admin panel

  • Aggregated pool statistics
  • Coin daemon & wallet RPC services stability monitoring
  • Log files data access
  • Users list with detailed statistics

Pool stability monitoring

  • Detailed logging in process console & log files
  • Coin daemon & wallet RPC services stability monitoring
  • See logs data from admin panel

Extra features

  • An easily extendable, responsive, light-weight front-end using API to display data
  • Onishin's keepalive function
  • Support for slush mining system (disabled by default)
  • E-Mail Notifications on worker connected, disconnected (timeout) or banned (support MailGun, SMTP and Sendmail)
  • Telegram channel notifications when a block is unlocked
  • Top 10 miners report
  • Multilingual user interface

Pools Using This Software

Usage

Requirements

 curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash
 sudo apt-get install -y nodejs
  • 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

  • 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 :

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

To login with this user :

sudo su - your-user

1) Downloading & Installing

Clone the repository and run npm update for all the dependencies to be installed:

git clone https://github.com/HospitalCoin/hospital-pool-nodejs.git pool
cd pool

npm update

2) Configuration

3) Start the pool

node init.js

The file config.json is used by default but a file can be specified using the -config=file command argument, for example:

node init.js -config=config_backup.json

This software contains four distinct modules:

  • pool - Which opens ports for miners to connect and processes shares
  • api - Used by the website to display network, pool and miners' data
  • unlocker - Processes block candidates and increases miners' balances when blocks are unlocked
  • payments - Sends out payments to miners according to their balances stored in redis

By default, running the init.js script will start up all four modules. You can optionally have the script start only start a specific module by using the -module=name command argument, for example:

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 Then enable and start the service with the following commands :

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 directory on file server capable of serving simple static files.

Edit the variables in the website_example/config.js file to use your pool's specific configuration. Variable explanations:

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:

Curl can be used to use the JSON-RPC commands from command-line. Here is an example of calling getblockheaderbyheight for block 100:

curl 127.0.0.1:18081/json_rpc -d '{"method":"getblockheaderbyheight","params":{"height":100}}'

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
