getLevelsSavepoint

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 (For this example, we use "NetXdQprcVkpaWU" as a placeholder)
const chainId = { chainId: 'NetXdQprcVkpaWU' };

// Fetch a list of savepoint levels for the specified chain
const savepointLevels = await tatum.rpc.getLevelsSavepoint(chainId);

// Log the list of savepoint levels
console.log('Savepoint levels:', savepointLevels);

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

Overview

The getLevelsSavepoint method allows you to retrieve a list of savepoint levels for a specific chain in the Tezos network. Savepoints are specific levels in the blockchain's history that can be used for various purposes, such as optimizing synchronization or rolling back to a specific point.

Example use cases:

1. Blockchain Optimization:
   Node operators and developers can use this method to obtain a list of savepoint levels to optimize their Tezos node's synchronization process by starting from a known savepoint.

2. Rollback Capability:
   Savepoints provide the ability to roll back the blockchain to a specific point in time. This can be helpful for handling issues or anomalies by reverting to a previous state.

3. Historical Data Retrieval:
   Researchers and analysts may use savepoints to fetch historical data for analysis and research purposes, ensuring consistent and accurate data retrieval.

Request Parameters

The getLevelsSavepoint method requires the following parameter:

• chainId (string, required):
  The identifier of the Tezos chain for which to retrieve the savepoint levels.

Return Object

The getLevelsSavepoint method returns an array of savepoint level objects, each containing relevant information about the savepoint level:

• block_hash (string): The hash of the block at the savepoint level, e.g., "BLockGenesisGenesisGenesisGenesisGenesisf79b5d1CoW2".
• level (integer): The level (block number) of the savepoint, e.g., 0.

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