getStateFork

Overview

The getStateFork endpoint allows you to retrieve information about the fork associated with a specific Ethereum Beacon Chain state.

Example use cases:

1. Fork Analysis: Developers can analyze and track forks in the Ethereum Beacon Chain to make informed decisions.
2. Network Monitoring: Network administrators and developers use this data to monitor the Ethereum 2.0 network and its forks.

Parameters

Returns

• execution_optimistic (boolean): true if the response references an unverified execution payload. Optimistic information may be invalidated at a later time. If the field is not present, assume the false value.
• finalized (boolean): If the response mentions the chain's final history picked by forks, it's true. Without the field, more calls are needed to compare the requested epoch with the final checkpoint.
• data (object ): The data object contains the following properties:
  • previous_version (string, hex): Previous fork version number
  • current_version (string, hex): Current fork version number
  • epoch (string): The epoch number

Request Example

// Import necessary libraries and modules
import { TatumSDK, Ethereum, Network } from '@tatumio/tatum'

// Initialize the Tatum SDK with Ethereum-specific parameters
const tatum = (await TatumSDK.init) < Ethereum > { network: Network.ETHEREUM }

// Specify the state ID
const StateId = 'your-state-id'

// Retrieve the state fork using the getStateFork method
const stateFork = await tatum.rpc.beacon.v1.getStateFork({ stateId: StateId })

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