High level overview​

This week, the Mithril team focused on supporting Cardano node v.10.4.1 and UTXO-HD in the aggregator, signer, and client.

They continued working on the DMQ node implementation, advancing the implementation of the local message submission and local message notification node-to-client mini-protocols in the Pallas library. They also worked on extending the aggregator metrics to record the usage of different client types.

Finally, they fixed a bug in the Cardano DB v2 snapshot that prevented full restoration and continued refactoring the STM cryptographic library.

High level overview​

This week, the Mithril team enabled incremental certification for the Cardano node database (version 2) on the release-mainnet network.

They continued work on the DMQ node implementation, completing the signature consumer and processor in the aggregator to support continuous signature handling, and added a mechanism to record the origin of each signature. The team also began adding support for UTXO-HD in the aggregator, signer, and client.

Finally, they addressed several bugs, improved CI workflows, and continued refactoring the STM cryptographic library.

High level overview​

This week, the Mithril team advanced the DMQ node implementation by finalizing the delayer and retrier decorators, enabling support for multiple signature publishers in the signer. They also implemented the signature consumer and processor in the aggregator to handle incoming signatures continuously.

The team re-implemented the GCP file uploader using a more robust library and addressed the cleanup of unexpected immutable files downloaded in snapshot archives.

Finally, they improved Cardano node restoration tests to ensure reliable restarts and continued refactoring the STM cryptographic library for better clarity.

High level overview​

This week, the Mithril team released the new distribution 2517.1, which addresses a client security issue discussed in this developer blog post. This version supports Cardano node v.10.3.1 and allows for signing ancillary files in the Cardano database snapshots using an IOG key. It also includes various bug fixes and improvements.

The team continued progressing on the DMQ node implementation by adjusting the cadence of the signer and aggregator state machines and developing the delayer and retrier decorators to support multiple signature publishers in the signer.

Finally, they worked on fixing some bugs in the infrastructure and kept refactoring the STM cryptographic library for improved clarity.

High level overview​

This week, the Mithril team released the pre-release version of the 2517.0-pre distribution. This version supports Cardano node v.10.3.1 and allows for signing ancillary files in the Cardano database snapshots using an IOG key. It also includes various bug fixes and improvements. The team continued implementing incremental certification for the Cardano database, also known as Cardano node database v2, which has been activated on the release-preprod test network.

The team has completed the proof of concept for the Mithril/ALBA aggregation proof system. They also simplified the configuration of the aggregator's commands and improved the dependency injection process. In addition, they implemented a publisher abstraction to facilitate the publication of signatures in the signer.

Finally, the team focused on speeding up the compilation time of Rust nodes and libraries, while continuing to refactor the STM cryptographic library for improved clarity.
