This week, the Mithril team continued working on the aggregator's prototype 'slave' mode to support signer registration across multiple aggregators. This feature is being stabilized and tested. They also focused on implementing incremental certification of the Cardano database, emphasizing feature stabilization, production readiness, testing, and optimization. Additionally, the team started refactoring the cryptographic library to improve clarity and maintainability and kept working on signing ancillary files in the Cardano database snapshots with an IOG key.

Finally, the team enhanced the database tooling for migration and maintenance and fixed some flakiness in the CI.

This week, the Mithril team continued implementing incremental certification of the Cardano database, focusing on feature stabilization and production readiness. They also worked on supporting the upcoming Cardano node v.10.2 and documenting the certification process for each certifiable data type.

Finally, the team completed cleaning up legacy code from the 'Thales' era and started working on a slave mode for the aggregator signer registration.

This week, the Mithril team released the new distribution 2506.0, which fixes a certificate chain security issue discussed in this developer blog post

The team continued implementing incremental certification of the Cardano database, completed the client library, client CLI, and monitoring, fixed bugs, and worked on unstable features. Additionally, they worked on decommissioning the testing-sanchonet Mithril network and ending support for macOS x64 pre-built binaries in the CI.

Finally, the team fixed all remaining flakiness in end-to-end tests in the CI and worked on cleaning up legacy code from the 'Thales' era.
