hasher-beamhash

This is a Node module for simple hashing and verifying Beam coin proof-of-work solutions. Most of the native code comes from or is adapted from Beam source code.

This module has been developed and tested on Node v10.17 and Ubuntu 16.04 for the Beam mining pool at MintPond.

Usage

Verify BeamHashII

const beamhash = require('@mintpond/hasher-beamhash');

/**
 * Verify a BeamHashII solution.
 *
 * @param inputBuf {Buffer}
 * @param nonceBuf {Buffer}
 * @param solutionBuf {Buffer}
 * @returns {boolean} True if valid, otherwise false.
 */
const isValid = beamhash.verify2(inputBuf, nonceBuf, solutionBuf);

if (isValid) {
    console.log('Valid solution');
}
else {
    console.log('Invalid solution');
}

Verify BeamHashIII

const beamhash = require('@mintpond/hasher-beamhash');

/**
 * Verify a BeamHashIII solution.
 *
 * @param inputBuf {Buffer}
 * @param nonceBuf {Buffer}
 * @param solutionBuf {Buffer}
 * @returns {boolean} True if valid, otherwise false.
 */
const isValid = beamhash.verify3(inputBuf, nonceBuf, solutionBuf);

if (isValid) {
    console.log('Valid solution');
}
else {
    console.log('Invalid solution');
}
