Usage

The stratum can be used as a module in a pool:

const Stratum = require('kawpow-stratum').Stratum;

class MyStratum extends Stratum {
    /* Override */
    canAuthorizeWorker(client, callback) {
        // implement your own logic
        if (client.minerAddress === 'bad') {
            // do not authorize worker
            callback(null/*error*/, false/*isAuthorized*/);
        }
        else {
            // authorize worker
            callback(null/*error*/, true/*isAuthorized*/);
        }
    }
}

const stratum = new MyStratum({
    coinbaseAddress: 'XyAY3TE3K29nrzQ2oo8JXyVPyGF3f7tq6P', // Only legacy addresses are supported for now
    blockBrand: 'Labyrinth solo miner',
    host: "0.0.0.0",
    port: {
        number: 3010,
        diff: 24 // Generally one share per 20-30 seconds is considered great. A good formula to start is hashrate in MHs*1.5
    },
    rpc: {
        host: '127.0.0.1',
        port: 4571,
        user: 'rpcuser',
        password: 'rpcpassword'
    },
    jobUpdateInterval: 55,
    blockPollIntervalMs: 250
});

stratum.on(Stratum.EVENT_SHARE_SUBMITTED, ev => {
    console.log(ev.share);    
});

stratum.init();

Start Script

There is a start script (start.js) included which contains a ready configuration fir mining.You will need to open and modify the config inside before running it.
