// Create a new block
const previousBlock = blockchain.getLastBlock();
const previousBlockHash = previousBlock.hash;
const nonce = 100; // For demonstration, in real-world scenarios, this would be calculated
const newBlock = blockchain.createNewBlock(nonce, previousBlockHash);

console.log('Blockchain:', blockchain.chain);
