High level overview​

The Mithril team released a new 2313.0 distribution that implements minor improvements and bug fixes. They continued implementing the migration of the aggregator stores to a relational design. They finished adaptating and migrating the certificate, epoch settings, signed entity type, signer registration and open message stores. Additionally, they completed the refactoring of the dependency injector of the aggregator and simplified its multi-signer in order for it to sign multiple concurrent messages.

Finally, the team has worked on designing the new architecture of the network to support signing multiple types of data and upgraded the version of the Cardano node used in the Mithril testnets and devnet to 1.35.6.

High level summary​

This week the consensus team finished the UTxO-HD prototype refactoring. We are now working on improving the DB lock mechanism to improve performance. We also introduced several improvements to the file system abstraction and simulation layer (fs-sim), which culminated in the release of fs-sim-0.1.0.0 and fs-api-0.1.0.0 to CHaP.

On the Genesis front we distributed the updated Genesis design document, soliciting feedback from Networking Team and IOG Researchers. We also opened up a PR for the adversarial leader schedule QuickCheck generator, which is being reviewed.

On the support front, we got a new Consensus version that can use different fundamental VRF crypto primitives for Babbage and Conway eras.

On the tech debt front we fixed an bug in the followers logic, which was discovered by our QuickCheck property tests.
