Great tutorial, was easy to understand for a novice TypeScript coder.
You can use nodejs built in hashing library for making the sha256 hash so no need to import js-sha256 libraries ;)
var crypto = require('crypto'); var hash = crypto.createHash('sha256').update(block.key).digest("hex");here is my complete generateHash method:
public generateHash(block: BlockData): string { let hash = crypto.createHash('sha256').digest("hex"); // mining while(!hash.startsWith(Array(this.difficulty + 1).join('0'))) { block.nonce += 1; hash = crypto.createHash('sha256').update(block.key).digest("hex"); console.log(block.nonce, hash); } return hash; }I din know that, was finding a library which supporr types haha. Thanks for sharing about this.
