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 () => {
// Options are not mandatory, defaults values:
const options = {
interval: 1000, // interval for "update"
port: 3002, // puppeteer port
host: 'localhost', // puppeteer host,
threads: -1 // number of threads to start with, defaults to navigator.hardwareConcurrency see https://coin-hive.com/documentation/miner#constructor-options
}
// Create miner
const miner = await CoinHive('ZM4gjqQ0jh0jbZ3tZDByOXAjyotDbo00', options); // 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
-
CoinHive(siteKey)
: Returns a promise of aMiner
instance. It requires a Coin-Hive Site Key. -
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
: InformshashesPerSecond
,totalHashes
andacceptedHashes
. -
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_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_THREADS
: Number of threads
- Node v8+
