    • HTTP RPC: Corrected an error triggered when querying the /state endpoint.

Added

  • 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.

0.2.0 - 2024-02-29

Changed

  • Default Rust toolchain switched to stable channel (as of 1.75).
  • Internal refactoring to how leaf actions in the state machine are organized.

Fixed

  • Node can now connect to the current berkeleynet after updates to:
    • Wire type definitions.
    • Verification, proving and circuits.
    • Ledger and transaction application logic.

Added

  • Ledger tests on CI.

0.1.0 - 2024-02-02

Fixed

  • Optimized scan state to reduce memory usage by avoiding duplication of data.
  • Updated proof verification to be compatible with the current berkeleynet (rampup4).

Added

  • Introduced support for producing proofs (blocks, payments, zkApp transactions, and merge proofs) compatible with the current berkeleynet (rampup4), with pending support for generating circuits.
  • Added the ability to produce blocks (excluding user transactions) for testing purposes.
  • Implemented pruning of inferior blocks post synchronization with the best tip.
  • Enhanced the testing framework and debugging support as follows:
    • Improved compatibility with the OCaml node within the testing framework.
    • Introduced declarations for essential invariants to be verified by the test framework, simulator, and replayer.
    • Integrated SNARK worker into the simulator for SNARK production.
    • Added functionality to store dumps of blocks and staged ledgers for inspection upon block application failure due to mismatches.

0.0.1 - 2023-12-22

First public release.

Added

  • Alpha version of the node which can connect and syncup to the berkeleynet network, and keep applying new blocks to maintain consensus state and ledger up to date.
  • Web-based frontend for the node.
