Changelog

All notable changes to ant-protocol will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

[2.3.0]

Changed

  • ADR-0004 (commitment-bound quote pricing): verify the new signed commitment fields (committed_key_count, commitment_pin) on single-node and merkle quote types; centralise StorageCommitment, commitment_hash, sidecar handling, and the shared calculate_price. Requires evmlib 0.9.0. Breaking wire change — part of the coordinated ADR-0004 cutover (evmlib → ant-protocol → ant-node/ant-client).

[2.0.0] — Unreleased

First release of the 2.x series. Not wire-compatible with previous 1.x releases published from a different repository under the same crate name.

Added

  • chunk — chunk protocol messages (ChunkMessage, ChunkPutRequest/Response, ChunkGetRequest/Response, ChunkQuoteRequest/Response, MerkleCandidateQuoteRequest/Response), protocol constants (CHUNK_PROTOCOL_ID, PROTOCOL_VERSION, MAX_CHUNK_SIZE, MAX_WIRE_MESSAGE_SIZE, DATA_TYPE_CHUNK, CLOSE_GROUP_SIZE, CLOSE_GROUP_MAJORITY, XORNAME_LEN), ProtocolError, and payment proof tag bytes (PROOF_TAG_SINGLE_NODE, PROOF_TAG_MERKLE).
  • data_types — address helpers (compute_address, xor_distance, peer_id_to_xor_name) and the DataChunk container.
  • chunk_protocol::send_and_await_chunk_response — subscribe/send/poll helper for chunk-protocol request/response exchanges over a saorsa-core::P2PNode.
  • payment::SingleNodePayment with pay (on-chain payment) and verify (on-chain verification) methods. verify rejects proofs whose median quote has zero price or zero paid amount.
  • payment::proof — PaymentProof, ProofType, and the serialize_single_node_proof / serialize_merkle_proof / deserialize_proof / deserialize_merkle_proof / detect_proof_type helpers.
  • payment::verify — ML-DSA-65 signature verification (verify_quote_content, verify_quote_signature, verify_merkle_candidate_signature).
  • devnet_manifest — DevnetManifest and DevnetEvmInfo POJOs for the devnet on-disk handoff file.
  • Transitive-dep re-export modules evm, transport, pqc so downstream crates can consume evmlib, saorsa-core, and saorsa-pqc through a single version pin.

Wire-level semantics

  • ChunkMessageBody, ChunkPutResponse, ChunkGetResponse, ChunkQuoteResponse, MerkleCandidateQuoteResponse, ProofType, ProtocolError, and Error are #[non_exhaustive].
  • ChunkMessage::decode rejects inputs larger than MAX_WIRE_MESSAGE_SIZE before deserialization.
  • chunk_protocol::send_and_await_chunk_response uses Instant::checked_add on the deadline to avoid panicking on out-of-range durations.
