Green Proof worker
Template for creating Green Proof worker using Nest. It mostly preconfigures communication with blockchain.
Example implementation:
import { Worker } from '@energyweb/worker';
const worker = new Worker({
privateKey: '035678b90179a...c4f078ac00bc45fc9fb674ddfe2f17c14f',
rpcUrl: 'https://rpc.url.com',
votingContractAddress: '0xCD2a3d9F938...c05AbC7FE734Df8DD826',
});
/*
* As first argument of callback function worker
* provides a runtime object with
* MerkleTree and VotingContract helpers
*/
worker.start(async ({ merkleTree, votingContract }) => {
// Get data that needs to ba validated
const input = await getInput()
// Execute some decentralized logic
const results = await decentralizedLogic(input);
// Create voting ID (it can be a hash of input data)
const inputHash = merkleTree.hash(input, 'input');
// Create merkle tree leaves of the results
const leaves = results.map((item, index) =>
merkleTree.hash(item, index));
// Create merkle tree
const { tree } = merkleTree.createMerkleTree(leaves);
// Get merkle tree root hash
const rootHash = tree.getHexRoot();
// Cast vote to voting contract
await votingContract.vote(inputHash, rootHash);
