node-mtp-reference-stratum

This is a reference MTP Stratum pool to aid in programmer development of Zcoin MTP (Merkle Tree Proof) miners and pools that use the MTP Stratum Protocol. It is not intended to be used in production as is.

This stratum has been developed and tested on Node v8.12 and Ubuntu 16.04

Usage

The MTP Stratum can be used as a module in a pool:

const StratumPool = require('mtp-reference-stratum').StratumPool;

const pool = new StratumPool({
    config: config,
    authorizeFn: authorizeFn
});

pool.on(StratumPool.EVENT_SHARE_SUBMITTED, function (e) {
    console.log(e);
});

pool.start();

Configuration

const config = {
    address: 'TBVKqLhVBt4aCwM5aPvUin5YU4ATHWUNpC', // pool wallet address
    daemon: {
        host: '127.0.0.1', // daemon ip/hostname
        rpcPort: 17101,    // rpc port
        user: 'rpcuser',   // rpc user name
        password: 'x'      // rpc password
    },
    port: {
        number: 3000,      // port number
        diff: 1            // difficulty
    }
}

AuthorizeFn

The authorize function is used to accept or deny worker authorizations.

function authorizeFn(worker, callback) {
    /* The "worker" argument is an instance of class.StratumWorker.js */
    if (worker.ipAddress === 'badguy') {
        callback({
            isAuthorized: false,
            error: [20, 'No bad guys allowed', null] // optional
        });
    }
    else {
        callback({
            isAuthorized: true
        });
    }
}

Start Script

There is a start script (start.js) included which contains further examples. It can also be run in order to get a Stratum going for test purposes. You will need to open and modify the config inside before running it.
