// Define the input parameters in a single object
const params = {
    round: 12345,  // Specify the round from which you want to fetch block hash information (integer).
};

// Get the block hash for the specified round
const blockHash = await tatum.rpc.getBlockHash(params);

// Log the block hash
console.log('Block Hash:', blockHash);

// Always destroy the Tatum SDK instance when done to stop any background processes
await tatum.destroy();
