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.

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.

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.

High level overview​

This week, the Mithril team focused on signing ancillary files in the Cardano database snapshots using an IOG key and on the proof of concept for the Mithril/ALBA aggregation proof system. They also worked on simplifying the aggregator’s command configuration and dependency injection. Additionally, they kept refactoring the STM cryptographic library to improve clarity.

Finally, the team investigated a communication problem in the signer when the attached Cardano node is restarted, and worked on accelerating the compilation time of the Rust nodes and libraries.

High level overview​

This week, the Mithril team started rolling out incremental certification of the Cardano database (also known as Cardano node database v2), which has been activated on the pre-release-preview test network.

They also completed adapting the infrastructure to support the aggregator’s prototype ‘follower’ mode and focused on signing ancillary files in the Cardano database snapshots using an IOG key. Work also continued on the proof of concept for the Mithril/ALBA aggregation proof system.

Finally, the team continued refactoring the STM cryptographic library to improve clarity and started refactoring the aggregator’s command configuration.
