High level overview​

This week, the Mithril team released the 2603.1 distribution. This version introduces support for the DMQ protocol, preliminary support for decentralized configuration, implementation of the Blockfrost API to fetch stake pool operators' pool tickers and names, and various bug fixes and improvements.

The team also focused on implementing the pre-aggregation SNARK primitives in the STM library and continued work on the non-recursive SNARK circuit MVP, including golden tests.

Additionally, they kept working on the new certification for Cardano blocks and transactions, implementing the signable builder and artifact routes in the aggregator REST API. They also completed documenting proposals for increasing the adoption of Mithril and DMQ nodes in Cardano.

Finally, the team fixed some bugs in the DMQ publisher and follower aggregator and continued updating the protocol security page.
