The Plutus team released version 1.29.0.0 of the Plutus libraries, which includes CIP-69 and CIP-117 implementations. The Mithril team improved the throughput of the prover route, transitioned to a chain point-based beacon for faster transaction signing, and prepared a threat modeling explainer for the documentation website. The ledger team continued testing the Conway era and fixed several bugs related to DRep expiry and committee voting thresholds. Intersect updates included interim constitutional committee elections and joining Hyperledger and the Linux Foundation. In Catalyst, town hall 165 shared updates, including the end of the community review period for LV0s and LV1s, and the start of LV2 moderation on June 13. The alternative voting mechanism achieved milestone 1 and was presented during town hall 165. The education team continued working on Mastering Cardano, supporting the DRep Pioneer Program, and preparing for the next Cardano Developer course.

The consensus team advanced the UTXO-HD project using simple diffs, improving mempool benchmarks. They released quickcheck-state-machine library v0.10.0 and rebased UTXO-HD on node v8.11. Technical working groups under Intersect were established, with Plutus and consensus meetings set for early June. Updates on UTXO-HD and Ouroboros Peras were provided. The Hydra team released node v0.17.0, featuring new commit transaction mechanisms and networking upgrades. The Mithril team released a protocol insights dashboard, updated the explorer page, and improved transaction certification. SanchoNet invites community testing for on-chain governance as per CIP-1694, with updated documentation. Project Catalyst hosted town hall 164, with the community review stage ongoing and Fund12 voting registration open. The education team is preparing lectures for the Cardano Developer Course, supporting the DRep Pioneer program, and writing content for Mastering Cardano.

Community-led governance takes another step forward

Cardano’s minimum viable on-chain governance framework outlines the transition towards on-chain governance, starting with an interim period for bootstrapping via formal rules. Key dates for community involvement include May 28 for registration opening, June 10 for closing, and June 13-23 for voting. An interim Constitutional Committee of seven members, including three elected community members, will oversee the initial phase. Community members passionate about governance are encouraged to apply.

This week, the ledger team focused on conformance testing, completing tests for CERT and RATIFY rules and improving the constraint-generators framework. They also fixed the stake pool operator stake distribution calculation for voting. The Plutus team developed guardrail scripts for Conway governance actions, fine-tuned the PlutusV3 cost model, and collaborated with MLabs on new bitwise primitives. The Mithril team worked on Cardano transaction certification, scaling proof generation, low-latency certification, and a new explorer page for SPOs. They upgraded the testing network and removed deprecated commands. Work continued on SanchoNet documentation and the DRep Pioneer program with Intersect. Fund12 reached the proposal finalization stage, and development on Hermes and Catalyst voices progressed well. The education team is planning the next Cardano Developer course, advancing the Mastering Cardano series, and preparing an educational video about the constitutional committee.

Research on MACS Algorithm Enhancing UTxO Coin Selection

The Cardano Foundation emphasizes innovation and research in blockchain technology. Their research paper, “MACS: A Multi-Asset Coin Selection Algorithm for UTxO-based Blockchains,” presented at the 2023 IEEE International Conference on Blockchain, highlights the benefits of the MACS algorithm. MACS optimizes transaction fees, UTxO pool size, and user privacy, improving UTxO-based blockchains. Though tested in simulations, it shows promise for enhancing cost, speed, and privacy in blockchain transactions, with further real-world testing needed.
