How to Use

// 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 
const chainId = { chainId : 'CHAIN_ID'};

// Fetch the details of the latest (head) block on the specified Tezos chain
const latestBlockDetails = await tatum.rpc.getBlocksHead(chainId);

// Log the latest block details
console.log('Latest Block Details:', latestBlockDetails);

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

Overview

The getBlocksHead method allows you to retrieve details about the latest (head) block on a specific Tezos chain. You can use this method to access key information about the most recent block, such as its hash, level, timestamp, and more.

Example Use Cases

  1. Real-Time Data Display:
    Developers can use this method to display real-time information about the latest block on a blockchain explorer or monitoring dashboard.

  2. Transaction Monitoring:
    Applications monitoring the Tezos blockchain can utilize this method to keep track of incoming transactions and their details.

  3. Network Analytics:
    Researchers and analysts can gather data from the latest block for network performance analysis and reporting.

Request Parameters

The getBlocksHead method requires the following parameter:

  • chainId (string, required):
    The identifier of the Tezos chain for which you want to retrieve the latest block details.

Return Object

The getBlocksHead method returns an object with details of the latest (head) block:

  • protocol (string): The protocol identifier, e.g., "PtNairobiyssHuh87hEhfVBGCVrK3WnS8Z2FT4ymB5tAa4r1nQf".
  • chain_id (string): The chain's unique identifier, e.g., "NetXdQprcVkpaWU".
  • hash (string): The hash of the latest block, e.g., "BLVRfBFc8Mb7s4PUacDfaeQTPj9HtzTNEArM1Ni1YbxRuK73htp".
  • level (integer): The level (block number) of the latest block, e.g., 4456790.
  • proto (integer): The protocol version, e.g., 17.
  • predecessor (string): The hash of the block's predecessor.
  • timestamp (string): The timestamp of the latest block, e.g., "2023-10-24T11:21:30Z".
  • validation_pass (integer): The number of validation passes, e.g., 4.
  • operations_hash (string): The hash of the operations included in the latest block.

(Note: There are additional fields in the response not covered in this list, such as fitness, context, and signature which provide further information about the block. The exact fields in the return object might vary based on the Tezos blockchain's implementation and version.)
