zk-threshold-proof/src/hash.js

A lightweight SDK to generate and verify ZK proofs that assert a private value is greater than or equal to a threshold.

const crypto = require('crypto');

function getCommitmentHash(publicSignals) {
  const hash = crypto.createHash('sha256');
  const data = publicSignals.join(',');
  hash.update(data);
  return '0x' + hash.digest('hex');
}
