Release v0.16.0

Added

• GraphQL: More queries (snark pool, pending snark work, genesis block, ledger status).

Changed

• GraphQL: Added more fields to daemonStatus query.

Fixed

• GraphQL: Some issues with accounts.
• Block Producer: Corner case that caused the won slot search to sometimes be interrupted at epoch bounds.

Release v0.15.0

Added

• Restored support for snark workers.
• Archive: Support for storing blocks to AWS, GCP and filesystem.
• Tooling: WebRTC traffic sniffer.
• GraphQL:
  • sendPayment mutation.
  • sendDelegation mutation.
  • pooledUserCommands query.
  • pooledZkappCommands query.
  • Various other partially implemented queries expanded to ensure compatibility with the OCaml node.

Changed

• P2P: Wait until full validation is complete before broadcasting transactions and completed works.
• Transition frontier: Perform cheap consensus operation first, and then the more expensive proof verification.
• Transaction pool: Unified libp2p and webrtc logic for the initial phase of handling transactions received from gossip network. As a result, processing of transactions received during bootstrap is delayed until the initial sync is complete.
• Transaction pool: Suspend processing during block production.

Fixed

• Transition frontier: Rare race condition in the case of forks during block production that could result in dropping staged ledgers too early.
• Webnode: Replaced tokio channels which had a race condition that could crash the thread on WASM.
• Transaction pool: Verify zkApp proofs in a dedicated thread to avoid blocking the state machine.

Release v0.14.0

Changed

• Rust Toolchain: Updated the minimum required Rust toolchain to version 1.84.
• Proofs: Optimizations (MSM, field inversion) that speed up proof production.

Fixed

• P2P: Correct handling of yamux windows limits
• P2P: Wait until full validation is complete before broadcasting blocks.
• WebRTC/P2P: Handle propagation of messages received from the WebRTC network to libp2p's gossip network (blocks, snarks and transactions).
• Transaction pool: Fixed checks for deep account updates when pre-validating transactions.

Added

• Archive mode: Added support for archive mode, which allows the node to connect to an archiver process and store node data in a database.

Release v0.13.0

Fixed

• Mempool: Inside the transaction and snark pool reducers, only broadcast locally injected transactions and producer snarks. Libp2p layer takes care of diffs received from gossip already.
• P2P: Don't forget the initial peers list.
• WebRTC connection leaks.
• zkApp transaction proofs are now verified on a separate thread.
• Sometimes produced blocks were broadcasted too early.
• OneOrTwo::zip never panics now, on failure it returns an error.

Changed

• On native, use jemalloc as the default allocator.
• Allocations reduced considerably by using stack-allocated bignums in the VRF evaluator.
• The same thread is now reused to verify all block proofs.
• RUST_BACKTRACE is always set to full now.

Release v0.12.0

Fixed

• Properly handle time in cases in which the system goes to sleep.
• Various corner cases in block proof production.
• Improved ledgers sync during bootstrap (be smarter about which peers to query).
• P2P: More efficient memory usage when managing the p2p state.
• P2P: Lower outgoing traffic by being more conservative about what is broadcasted to each peer.
• P2P: Better handling of disconnections.
• VRF: Correctly handle cases in which the delegator table is empty.
• Webnode: Peer connection handling improvements.

Changed

• Rust Toolchain: Updated the minimum required Rust toolchain to version 1.83.
• Webnode: Reduced startup time by loading prover indexes in parallel to the bootstrap process.
• Webnode: Faster field operations (faster hashing and proving).
• Improved hashing performance by caching and reusing common prefixes.
• Added more pre-validation checks for blocks received from the network.

Added

• Webnode: Transaction propagation
• P2P: Support for specifying the external ip to be advertised.

Release v0.11.0

Added

• Webnode: Peer discovery and p2p based signaling (so that webnodes can find each other).
• Webnode: Connection authentication.
• Support for specifying external IPs.

Fixed

• Ledger: Fixed a regression introduced in v0.10.0 that caused the ZKApp precondition checks ordering to not match the OCaml implementation's exactly, which resulted in block application failures.
• Ledger: Corrected handling of custom tokens in the block application logic.
• P2P: Reduced excessive outgoing traffic.
• P2P: Yamux fixes and improvements (backpressure).
• Webnode: Staging ledger sync timeout.

Release v0.10.3

Added

• Support for name resolution in peer addresses.
• Block producer docker compose setup.
• WASM file containing the webnode is now included in the frontend image.
• Logging output to the filesystem in addition to stdout.
• Webnode: peer discovery and p2p based signaling.

Release v0.10.0

Added

• GraphQL endpoints for o1js.
• Support for batched verification of proofs.
• Enabled full proof verification of completed works included in blocks.

Changed

• Deduplication of zkApp logic.
• Various internal improvements.

Fixed

• Regression in the verification zkApp transactions with feature flags (introduced when upgrading proof-systems).
• Potential overflow in yamux.
• Added a missing check for next epoch seed finality

Release v0.9.0

Stability improvements release

Fixes

• Many bugfixes, performance, security and stability improvements.

Release v0.8.14

Fixed

• Correctly show transaction fee values in the frontend.
• Make sure that incorrectly encoded finite field values are handled properly.
