High level overview​

This week, the Mithril team released the 2630 distribution. This version promotes the DMQ node 0.7.0.0 as beta on the release-mainnet and release-preprod networks, activates the testing phase of the Cardano blocks and transactions certification on the pre-release-preview and release-preprod networks, removes the support for the CardanoImmutableFilesFull certificate type in the Mithril signer and aggregator, and includes various bug fixes and improvements.

The team also completed the assessment of the catchup from the genesis certificate for a SNARK follower aggregator and the encoding of the aggregate signature of the certificate message as bytes, and stopped forcing the rustls TLS backend in the future_snark feature of the STM library. They continued combining the dual MSM and accumulator pairing checks in the IVC proof verification, and reusing the cached unsafe SRS in the SNARK test setups.

They also completed the creation of a local IPFS network for a proof-of-concept of decentralized delivery of Cardano database artifacts, and continued implementing the aggregator CLI commands and the new chain adapter for on-chain configuration parameters, as well as the runbook documenting them.

Finally, the team upgraded the documentation website to Docusaurus 3.10.2 and tailwind v4, completed shipping the Mithril signer node binary in the Cardano node bundle, and continued upgrading to Cardano node v.11.1 and fixing the flakiness of the end-to-end tests in the CI.
