v0.14.3

Tags or hashes:

• monad-bft (consensus): tag v0.14.3 (f2a2092b)
• monad (execution): tag v0.14.3 (7fcd693f7)

Highlights

• Authenticated UDP enforcement — Raptorcast now requires wire-authenticated UDP sockets (previously optional, now enforced)
  • Ref: monad-bft PR #2956

Notable robustness changes

• [Execution] Fix DbCache assert-fail when reading finalized state older than latest finalized block
  • Ref: monad (execution) PR #2190
  • Replaces assertion with explicit checks; fixes incorrect truncated value propagation when walking the chain back past the latest finalized block
• [Execution] Raise MIN_HISTORY_LENGTH floor from 257 to 300
  • Ref: monad (execution) PR #2217
  • Execution requires 256 history blocks for the block hash buffer; the old floor of 257 left only a one-block margin. Under disk pressure, history could shrink below 256 after a restart, forcing a full statesync. New floor gives ~44 blocks of headroom; also bumps the stored cap on existing DBs at init time so nodes carried over from an older binary aren't pinned at 257.
• [Execution] Fix evm-as PushLabel encoding at offset zero for pre-Shanghai targets
  • Ref: monad (execution) PR #2213
  • Fixes incorrect PUSH0 encoding in the EVM assembler for pre-Shanghai code paths

Notable performance changes

• [Execution] Extend trie span optimization to fnext, child_off, and SharedPtr arrays
  • Ref: monad (execution) PR #2176
• [Execution] Remove inflight read coalescing from rwdb find path
  • Ref: monad (execution) PR #2183
• [Execution] Elide DB fetch in State::is_touched
  • Ref: monad (execution) PR #2198
• [RPC] Skip redundant receipt conversion on log retrieval path
  • Ref: monad-bft PR #2839
  • Avoids building a full TransactionReceipt when serving log queries; goes directly from (TxEnvelope, Receipt) to ReceiptEnvelope, reducing overhead on eth_getLogs and related calls

Notable internal changes

• [Consensus] Peer discovery: require authenticated UDP in name records
  • Ref: monad-bft PR #2955
  • Enforces non-zero port policy for authenticated UDP; port 0 was used as an empty value in RLP-encoded peer entries and is now rejected
• [Consensus] Add full nodes message type and handling logic for peer reputation scoring
  • Ref: monad-bft PR #2914, PR #2915
  • Introduces a new message type for full nodes to send peer participation data to the publisher for reputation scoring
• [Consensus] Peer discovery: drop V1 wire name records
  • Ref: monad-bft PR #2952
  • Removes backward compatibility with V1 peer wire format; all peers must use V2 name records
• [Consensus] Expose block number by hash retrieval in archive
  • Ref: monad-bft PR #2980
  • Archive nodes now support block number lookup by block hash
• [Consensus] Raptorcast: round-robin mode for stake-proportional chunk assigner
  • Ref: monad-bft PR #2970
  • Adds round-robin assignment to the stake-proportional chunk assigner used in deterministic Raptorcast
• [Consensus] Raptorcast: require authenticated UDP socket
  • Ref: monad-bft PR #2956
  • Enforces authenticated UDP socket setup in raptorcast; previously optional
