Equihash Proof of Work for Node

Equihash is a tunable asymmetric proof of work algorithm where it is difficult to generate a proof, but easy to verify one. The algorithm makes it difficult to build custom hardware to generate the proof by ensuring forced CPU and memory trade offs. The algorithm is useful for cryptocurrency mining as well as building solutions that require a proof of work capability.

Installation

install equihash

The Equihash API

• solve(input, options, callback(err, proof))
• verify(input, proof)

Usage Example

t equihash = require('equihash')('khovratovich');

nput seed for equihash (up to 512 bits)
t input = crypto.createHash('sha256').update('test1234', 'utf8').digest();
t options = {
 90,
 5


hash.solve(input, options, (err, proof) => {
(err) {
return console.log('Failed to generate proof:', err);


nsole.log('Equihash proof:', proof)
nsole.log('Valid proof? ', equihash.verify(input, proof));

Test Suite
