Mine cryptocurrency Monero (XMR) using Coin-Hive from node.js

This project has nothing to do with coin-hive.com

npm install -g coin-hive

const CoinHive = require('coin-hive');
(async () => {

  // Create miner
  const miner = await CoinHive('ZM4gjqQ0jh0jbZ3tZDByOXAjyotDbo00'); // Coin-Hive's Site Key

  // Start miner
  await miner.start();

  // Listen on events
  miner.on('found', () => console.log('Found!'))
  miner.on('accepted', () => console.log('Accepted!'))
  miner.on('update', data => console.log(`
    Hashes per second: ${data.hashesPerSecond}
    Total hashes: ${data.totalHashes}
    Accepted hashes: ${data.acceptedHashes}
  `));

  // Stop miner
  setTimeout(async () => await miner.stop(), 60000);
})();

Usage: coin-hive <site-key>

<site-key>: You CoinHive Site Key

Options:

  --interval  Interval between updates (logs)
  --port      Port for the miner server
  --host      Host for the miner server
  --threads   Number of threads for the miner
  --proxy     Proxy socket 5/4, for example: socks5://127.0.0.1:9050

• CoinHive(siteKey [, options]): Returns a promise of a Miner instance. It requires a Coin-Hive Site Key. The options object is not mandatory and may contain the following properties:

  • interval: Interval between update events in ms. Default is 1000.

  • port: Port for the miner server. Default is 3002.

  • host: Host for the miner server. Default is localhost.

  • threads: Number of threads. Default is navigator.hardwareConcurrency (number of CPU cores).

  • proxy: Puppeteer's proxy socket 5/4 (ie: socks5://127.0.0.1:9050).

• miner.start(): Connect to the pool and start mining. Returns a promise that will resolve once the miner is started.

• miner.stop(): Stop mining and disconnect from the pool. Returns a promise that will resolve once the miner is stopped.

• miner.kill(): Stop mining, disconnect from the pool, shutdown the server and close the headless browser. Returns a promise that will resolve once the miner is dead.

• miner.on(event, callback): Specify a callback for an event. The event types are:

  • update: Informs hashesPerSecond, totalHashes and acceptedHashes.

  • open: The connection to our mining pool was opened. Usually happens shortly after miner.start() was called.

  • authed: The miner successfully authed with the mining pool and the siteKey was verified. Usually happens right after open.

  • close: The connection to the pool was closed. Usually happens when miner.stop() was called.

  • error: An error occured. In case of a connection error, the miner will automatically try to reconnect to the pool.

  • job: A new mining job was received from the pool.

  • found: A hash meeting the pool's difficulty (currently 256) was found and will be send to the pool.

  • accepted: A hash that was sent to the pool was accepted.

• miner.rpc(methodName, argsArray): This method allows you to interact with the Coin-Hive miner instance. It returns a Promise that resolves the the value of the remote method that was called. The miner intance API can be found here. Here's an example:

var miner = await CoinHive('SITE_KEY');
await miner.rpc('isRunning'); // false
await miner.start();
await miner.rpc('isRunning'); // true
await miner.rpc('getThrottle'); // 0
await miner.rpc('setThrottle', [0.5]);
await miner.rpc('getThrottle'); // 0.5

All the following environment variables can be used to configure the miner from the outside:

• COINHIVE_SITE_KEY: Coin-Hive's Site Key

• COINHIVE_INTERVAL: The interval on which the miner reports an update

• COINHIVE_THREADS: Number of threads

• COINHIVE_PORT: The port that will be used to launch the server, and where puppeteer will point to

• COINHIVE_HOST: The host that will be used to launch the server, and where puppeteer will point to

• COINHIVE_PUPPETEER_URL: In case you don't want to point puppeteer to the local server, you can use this to make it point somewhere else where the miner is served (ie: PUPPETEER_URL=http://coin-hive.herokuapp.com)

• COINHIVE_PROXY: Puppeteer's proxy socket 5/4 (ie: COINHIVE_PROXY=socks5://127.0.0.1:9050)
