Release v0.3.0

Changes

• Rust Toolchain: Updated the minimum required Rust toolchain to version 1.77.
• Networking:
  • Libp2p Replacement: Transitioned from libp2p to a custom internal networking implementation. The transition will be finalized in the next release, completely removing the libp2p dependency.
    • Gossipsub: Pending support. Current version of the node performs initial bootstrapping but cannot stay synchronized with network broadcasts.
    • Kademlia: Partial implementation includes bootstrapping and FIND_NODE server/client functionalities.
    • Identify Protocol: Absent in this release, rendering the node unusable as a seed node.
• Frontend:
  • Mobile Compatibility: Enhanced support for mobile platforms, improving user experience across various devices.

Fixes

• Staged Ledger: Resolved an issue where the ledger reconstruct step would block the state machine.
• Node Communication: Fixed a bug where nodes did not respond to ledger queries from bootstrapping peers, enhancing network cooperation.
• Frontend:
  • Test Stability: Addressed and fixed previously failing tests.
• Backend:
  • HTTP RPC: Corrected an error triggered when querying the /state endpoint.

Additions

• Bootstrap Efficiency:
  • Ledger Synchronization: Optimized the snarked ledger synchronization process during bootstrap, significantly reducing the time required.
  • Genesis Ledger Loading: Enhanced the loading mechanism for the genesis ledger, achieving much faster startup times.
• Frontend Enhancements:
  • Network Node DHT view.
  • Network Bootstrap Stats for real-time monitoring of network bootstrap statistics.
  • Main Dashboard view.
• Backend Improvements:
  • JsonPath Support: Enhanced the /state HTTP RPC endpoint with JsonPath support, offering more flexible state querying capabilities.
