The Mithril team progressed on incremental certification of the Cardano database and prepared for the upcoming 'Pythagoras' era transition. The Leios team advanced both Haskell and Rust implementations to enhance performance and simulation fidelity.

The January 24, 2025, development report highlights consensus team progress on security, documentation, and Peras workstream improvements. The UTXO-HD branch achieved successful local chain synchronization. The performance team benchmarked node v.10.1.4 and introduced a tracing Discord channel. Plutus added the Fix construct and CLI tool guides. Hydra completed custom ledger experiments and restored hydra-explorer. Mithril advanced incremental database certification. The Leios team benchmarked efficient VRF cryptography.

The January 17, 2025, development report focuses on final preparations for the Plomin hard fork, including bug fixes and code simplifications. Stake pool operators are urged to upgrade to node v.10.1.4. Lace v.1.18.2 improved crash recovery and fixed CIP-95 bugs. Mithril certified stake distribution on the mainnet and upgraded to node v.10.1.4. The Ouroboros Leios project progressed simulations to enhance network throughput. Voting for the Plomin hard fork continues.

The January 10, 2025, development report highlights the release of Cardano node v.10.1.4, preparing for the Plomin hard fork with enhanced mempool safeguards. The consensus team improved time management and block-fetch synchronization. Plutus Core is finalizing the data-backed ScriptContext API for better script performance. Hydra advanced incremental commits and multi-version support for its explorer, while Mithril released distribution 2450.0, supporting Cardano node v.10.1.3.

The December 13, 2024, development report concludes the year, with updates resuming January 10, 2025. The networking team, in collaboration with the Cardano Foundation, noted 98.4% of transactions are included within two blocks, showing minimal congestion. The consensus team advanced UTXO-HD and reviewed low participation handling. Daedalus v.7.0.2 launched, enabling users to delegate voting power to DReps or select automatic voting options, enhancing governance participation.

The SRE team released Cardano node v.10.1.3 and DB Sync updates, improving mainnet bootstraps and dashboards. The ledger team fixed a bug in protocol version 10 and added a query for DRep voting stake distribution. Mithril advanced incremental certification and enhanced certificate verification. The Constitutional Convention in Buenos Aires and Nairobi ratified a new Cardano constitution. Catalyst Fund13 voting continues until December 12, with over 1.5 billion ada in voting power. The education team held Cardano Days sessions and demonstrated live node use with a mobile SPO learning lab.

The consensus team refined Praos documentation and addressed chain growth violations. DB Sync v.13.6.0.2 improved rollbacks, Lace v.1.17.5 enhanced syncing, and Hydra advanced API filtering. Mithril introduced a one-line installer and new certifications. Catalyst Fund13 voting began on November 28, and the Constitutional Convention on December 4–6 will address the Cardano constitution. A proposal suggests renaming Chang #2 to the Plomin hard fork.

The core technology teams released components compatible with the latest Cardano node, including DB Sync and Cardano wallet updates. The ledger team shared the ImpSpec framework, while performance teams enhanced benchmarking and locli analysis. Mithril prepared for the Pythagoras era, and Hydra's Doom tournament qualifiers start December 3. The Constitutional Convention will vote on the Cardano constitution, and the community may rename Chang #2 to the Plomin hard fork.
