getStateFinalityCheckpoints

Overview

The getStateFinalityCheckpoints endpoint allows you to retrieve the finality checkpoints associated with a specific stateId.

Example use cases:

1. Finality Assessment: Developers can use finality checkpoints to assess the level of finality reached by the Ethereum Beacon Chain. By examining the previous_justified, current_justified, and finalized checkpoints, they can determine the state of consensus and the security of the network.
2. Validator Monitoring: Validators in the Ethereum 2.0 network can use finality checkpoints to monitor the progress and stability of the network. They can track changes in the previous_justified and current_justified checkpoints to ensure they are participating in a secure and finalized chain.
3. Network Stability Analysis: Network administrators and developers can monitor the network's finality checkpoints to assess its stability. Sudden changes or deviations in the previous_justified, current_justified, and finalized checkpoints may indicate issues or attacks on the network, prompting immediate action.

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 finality checkpoints with the following structure:
  • previous_justified (object): Provides information about the previous justified beacon block.
    • epoch (string): The corresponding epoch
    • root (string): The corresponding root
  • current_justified (object): Provides information about the current justified beacon block.
    • epoch (string): The corresponding epoch
    • root (string): The corresponding root
  • finalized (object): Provides information about the finalized beacon block.
    • epoch (string): The corresponding epoch
    • root (string): The corresponding root

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 finality checkpoints using the getStateFinalityCheckpoints method
const finalityCheckpoints = await tatum.rpc.beacon.v1.getStateFinalityCheckpoints({ stateId: StateId })

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