How to use it

// Import required libraries and modules from Tatum SDK
import { TatumSDK, Tezos, Network } from '@tatumio/tatum';

// Initialize the Tatum SDK for Tezos
const tatum = await TatumSDK.init<Tezos>({ network: Network.TEZOS });

// Define the chain ID and block ID (Replace placeholders with actual values)
const params = { 
    chainId: 'YOUR_CHAIN_ID',           // Specify the chain ID (Network identifier)
    blockId: 'YOUR_BLOCK_ID',           // Optional: Specify the block ID (hash)

// Fetch the hash of a specific block by its ID
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();


The getBlockHash method allows you to retrieve the hash of a specific block within a Tezos chain. By providing the chain ID and block ID as parameters, you can access the unique hash associated with the chosen block.

Example use cases:

  1. Block Identification: Developers and applications can use this method to identify and reference a specific block on the Tezos blockchain using its hash.

  2. Transaction Verification: When verifying transactions or interactions with smart contracts, you may need the block hash as part of the verification process.

  3. Historical Data Retrieval: Researchers and analysts can retrieve block hashes for historical data analysis and record-keeping.

Request Parameters

The getBlockHash method requires the following parameters:

  • chainId (string, required): The identifier of the Tezos chain from which to retrieve the block hash.

  • block (string, required): The unique identifier (hash) of the block for which you want to retrieve the hash.

Return Object

The getBlockHash method returns a string representing the hash of the requested block.

(Note: The exact fields in the return object might vary based on the Tezos blockchain's implementation and version.)
