category-labs/monad-bft v0.14.0-rc.1

on GitHub

v0.14.0-rc.1 is ready for testing. This release includes ~400ms faster receipt queries, a new eth_fillTransaction RPC endpoint, lower-latency websocket notifications, and numerous robustness and performance improvements across consensus and execution.

Note: This is a pre-release for testing and validation only. Not recommended for production use. If you run into any issues, please include Release: v0.14.0-rc.1 in the name of any issues you create.

⚠️ Breaking Changes

• Auth UDP now required — self_auth_port and authenticated_bind_address_port fields in node.toml are now required. Nodes without these fields will fail to start. (PR #2891)
• raptor10_fullnode_redundancy_factor max lowered from 7→3 (default is 3, most nodes unaffected). (PR #2852)

Tags or hashes:

• monad-bft (consensus): tag v0.14.0-rc.1 (d1d17916)
• monad (execution): tag v0.14.0-rc.1 (54e132cfa)

Highlights

• ~400ms faster receipt queries — Receipts now tracked in chainstate buffer and available at Proposed time, eliminating trie lookups.
• eth_fillTransaction — New RPC endpoint to get a fully populated transaction without signing.
• Websocket notifications on proposed blocks — newHeads and logs subscriptions now emit on proposed blocks instead of voted, reducing notification latency.
• Archive: per-source AWS profile support — Archiver source/sink/fallback now supports --profile flag for AWS credentials isolation. Reads from .aws/credentials and .aws/config. (PR #2865)
