v0.16.2

Tags or hashes:

• monad-bft (consensus): tag v0.16.2 (4374d389e)
• monad (execution): tag v0.16.2+1 (aae93c535)

Highlights

• Raptorcast v1 publish — nodes now publish proposals in the v1 raptorcast wire format on both
  the primary and secondary paths.
• JSON-RPC error codes corrected across eth_call, eth_estimateGas, eth_simulateV1,
  debug_* and txpool_*.
• Raptorcast throughput improved ~16.7% under multi-target load.

Notable protocol changes

• [Consensus] Raptorcast advances to the accept_both_publish_v1 stage; nodes publish proposals
  in the v1 wire format on both primary and secondary paths.
  • Ref: monad-bft PR #3177
• [Consensus] AdvanceRound is published to full nodes via broadcast rather than secondary
  raptorcast, avoiding a collision with the proposal commitment under v1.
  • Ref: monad-bft PR #3176

Notable RPC/SDK changes

• [RPC] Fix JSON-RPC error codes and messages returned by the call, simulate, debug, txpool and
  websocket handlers.
  • Ref: monad-bft PR #3228
• [RPC] Fix zero-fee eth_calls — a zero maxFeePerGas is no longer raised to the base fee,
  matching geth and reth.
  • Ref: monad-bft PR #3164
• [RPC] Fix EIP-1898 compatibility for BlockTagOrHash.
  • Ref: monad-bft PR #3163
• [RPC] eth_createAccessList now accepts state overrides.
  • Ref: monad-bft PR #3179

Notable robustness changes

• [Consensus] A validator publishes only the first accepted proposal to its full nodes, so an
  equivocated proposal is no longer forwarded.
  • Ref: monad-bft PR #3180
• [RPC] Concurrency limiter for eth_feeHistory, bounding memory on large block ranges.
  • Ref: monad-bft PR #3212
• [EVM] Runloop fix for when the node resets to the start block number.
  • Ref: monad (execution) PR #2501

Notable performance changes

• [Consensus] Raptorcast avoids redundant wire-auth lookups in the authenticated send path —
  15,796 to 18,427 chunks/s.
  • Ref: monad-bft PR #3223

Notable internal changes

• [Node ops] Nodes can opt out of serving statesync requests. Optional node.toml setting,
  default unchanged.
  • Ref: monad-bft PR #3208
• [Node ops] Update the openssl crate to 0.10.81, closing seven advisories. Reached only
  through monad-rpc with a MongoDB archive backend configured; monad-node does not link it.
  • Ref: monad-bft PR #3191
• [EVM] Seed Address, bytes32 and StorageKey hashing per process, so colliding keys cannot
  be precomputed against node-local maps.
  • Ref: monad (execution) PR #2462
• [EVM] Replace silkpre's ECRECOVER precompile with a vendored monad_recover_address on system
  libsecp256k1. Adds a libsecp256k1-dev build dependency outside the published Docker images.
  • Ref: monad (execution) PR #2437
• [EVM] Allow dual-db commit in runloop_monad_ethblocks where secondary_db is optional.
  • Ref: cherry-pick from staging-v0.16.1 (df14e67bb)
• [EVM] Consolidate dual-db mirroring with for_each_db.
  • Ref: cherry-pick from staging-v0.16.1 (d836afc18)
