🚀 Features

Core Library Enhancements

• Chain Synchronization:

  • Intersection Finding: Automatically locate a starting point for synchronization between the client and the blockchain.
  • Real-Time Updates:
    • Roll Forward: Process new blocks as they are added to the blockchain.
    • Roll Backward: Handle reorganizations by reverting to the last common point.
  • Pipelining: Optimize synchronization performance with multiple simultaneous requests, reducing latency and maximizing bandwidth.
  • Era-Specific Synchronization: Focus on era transitions or specific block milestones.
  • Rate Limiting: Control block requests using the MaxBlocksPerSecond configuration, preventing overloads.
  • Multiple Parallel Connections: Initiate connections from different starting points, improving synchronization times and resource efficiency.

• Memory Pool Monitoring:

  • Acquire Mempool Snapshots: Use AcquireMempoolAsync to get consistent snapshots of the mempool for transaction querying.
  • Transaction Management:
    • Check for specific transactions with HasTransactionAsync.
    • Retrieve transactions sequentially using NextTransactionAsync.
  • Mempool Insights:
    • Query the size, transaction count, and capacity of the mempool using SizeOfMempoolAsync.
  • Release Resources: Free resources with ReleaseMempoolAsync when snapshots are no longer needed.
  • Graceful Shutdown: Cleanly close WebSocket connections with ShutdownAsync.
