This library helps you to notarize and timestamp single documents or large sets of documents (with merkle trees), using the immutable lisk blockchain.
import { Notarize } from 'lisk-notarize';
const n = Notarize();
n.setFile('~/file1.txt');
const h = n.build();
console.log(`Root: ${h.root}`);
const txres = n.broadcast({
network: 'testnet',
secret: '...',
secret2: '...'
});
import { NotarizeTree } from 'lisk-notarize';
const n = NotarizeTree();
n.addFile('~/file1.txt');
n.addFile('~/file2.txt');
const h = n.build();
console.log(`Root: ${h.root}, Tree: ${h.tree}`);
const txres = n.broadcast({
network: 'testnet',
secret: '...',
secret2: '...'
});
