get_block_info

{% hint style="warning" %}
Please note that you are able to get data only from block number 260742168 and newer.
{% endhint %}

Overview

The get_block_info method retrieves crucial information about a specific block in the EOS blockchain. It returns an object containing details such as block time, block number, previous block ID, producer, and transaction count. Similar to get_block but returns a fixed-size smaller subset of the block data.

// yarn add @tatumio/tatum

import { TatumSDK, Eos, Network } from '@tatumio/tatum'

const tatum = await TatumSDK.init<Eos>({ network: Network.EOS })

const blockInfo = await tatum.rpc.getBlockInfo()

await tatum.destroy() // Destroy Tatum SDK - needed for stopping background jobs

Example use cases:

1. Fetching Specific Block Details:
   Developers and users may utilize the get_block_info method to gather information about a particular block, aiding in debugging or validating blockchain states and transactions.

2. Block Verification:
   Validators and network participants can employ this method to verify the integrity and authenticity of a block, ensuring the security and reliability of the network.

3. Data Analysis and Chain Exploration:
   Blockchain analysts and enthusiasts might use get_block_info to study block patterns and transaction activities, gaining insights into the network’s operations and behaviors.

Request Parameters

The getBlockInfo method requires the following parameter in the request body:

• blockNumOrId (string, required): It could be either a block number or a block ID.

Return Object

The get_block_info method returns an object containing the following parameters:

• block_num (integer): The block number.
• ref_block_num (integer): The reference block number.
• id (string): The ID of the block.
• timestamp (string): The timestamp when the block was produced.
• producer (string): The name of the block producer.
• confirmed (integer): The number of confirmed transactions in the block.
• previous (string): The ID of the previous block.
• transaction_mroot (string): The Merkle root of the transactions in the block.
• action_mroot (string): The Merkle root of the actions in the block.
• schedule_version (integer): The schedule version.
• producer_signature (string): The signature of the block producer.
• ref_block_prefix (integer): The reference block prefix.
