Consensus Team Update
· 3 min read
High level summary
- Leios prototype and design (Treasury Funding Initiative 4: Ouroboros Leios Implementation):
- Continued to harden the Leios testnet with a round of prototype fixes across consensus and the node (#2113, #6614), and cut two prototype releases carrying this work,
prototype-2026w27a(#978) andprototype-2026w28(#986). - Fixed two bugs found while running the testnet. The node no longer applies uncertified endorser blocks from the immutable database on startup, and the LeiosNotify pipelining depth was increased (#2114). A startup crash caused by a race condition on a node's first run was also resolved (#2115, fixing ouroboros-leios#983).
- Added a voting dashboard to make Leios easier to observe, showing how endorser blocks are voted on and certified (ouroboros-leios#985).
- Reviewed a change to how the node certifies and applies endorser blocks that is expected to roughly double the certification rate and raise throughput (#2105).
- Drafted prose for the Leios high-level design document, describing how the pieces of the protocol fit together (commit 13e3908), and started negotiating the interface between Consensus and Ledger for Leios with the Ledger team (ouroboros-leios#977).
- Continued to harden the Leios testnet with a round of prototype fixes across consensus and the node (#2113, #6614), and cut two prototype releases carrying this work,
- Node diversity and conformance (Treasury Funding Initiative 17: Maintenance and Support):
- Took part in node diversity meetings on conformance testing with the Amaru team and others, including working through a conformance hurdle specific to the
previewnetwork. - Discussed how to specify the mempool and transaction submission precisely enough that other node implementations can follow the same rules.
- Took part in node diversity meetings on conformance testing with the Amaru team and others, including working through a conformance hurdle specific to the
- UTXO-HD snapshot tooling (Treasury Funding Initiative 10: LSM including UTXO-HD):
- Improved the
snapshot-convertertool's--helpand--versionoutput, making it clearer how to convert ledger snapshots between the in-memory and on-disk (LSM) formats (#2098). - Added a temporary workaround so
snapshot-converterreads the bloom-filter salt directly from exported files, until a proper fix lands on the LSM-trees side (#2097, pending lsm-tree#855).
- Improved the
- Documentation (Treasury Funding Initiative 17: Maintenance and Support):
- Added a reference document describing the metrics and tracing available for observing Ouroboros Genesis (#2103).
