High level overview​

The Mithril team has released the new distribution 2248.1 of their nodes. They have published the first version of the Mithril cryptographic library on crates.io, the Rust community’s crate registry. They have implemented an optimization on the individual signatures that no longer embed the verification key and stake. They have also enhanced their testing strategy by implementing a workflow that tests that the client binaries produced for multiple platforms (Linux, MacOS and Windows) are able to verify and restore snapshots.

Finally, they have kept on simplifying the aggregator node's multi-signer by removing the signer registration and the certificate creation from its responsibilities.

High level overview​

The Mithril team worked on finalizing their release process by adding new features: publishing their cryptographic library to the Rust community, adding node versions manifest in the release notes, and signing the binaries embedded in the distributions. They deprecated the declarative signer node registration that will be decommissioned in a few weeks. The team also completed the automatic store upgrade process for the signer and aggregator nodes.

Finally, the team continued working on the redaction of the CIP that will allow the decentralization of Mithril by using the Cardano networking layer.

Low level overview​

• Implemented custom Mithril SPOs on testing/pre-release networks #563
• Deprecated Signer Declarative Pool Id registration mode #585
• Completed the second stage of the store automatic migration process #600
• Completed the deployment pipelines to crates.io registry #588
• Completed automatic generation of nodes/libraries versions manifest in releases notes #599
• Completed CI/CD handling of PR from forks #597
• Worked on the CIP design for Mithril piggybacked on the Cardano network layer #586
• Worked on signing the artifacts released in the distributions by the CI/CD #587
• Worked on multi-platforms end to end test #601
• Worked on the refactorizaton of the aggregator multi-signer engine #398

High level overview​

The Mithril team has released their second distribution 2246.1 following the activation of the alpha version of the new release process. They continued refining its implementation and added a new set of artifacts to the distributions, such as Debian packages and macOS/Windows binaries. The team also enhanced the Mithril Explorer, which now provides more detailed information about epoch settings and easier access to multiple aggregators for the users. They have also worked on an enhanced mechanism for node versioning, storage, and communication protocol. They also implemented version detections for the signer and aggregator nodes, designed the automatic store upgrade feature for these nodes, and enhanced the documentation of the configuration parameters of the several Mithril networks.

Finally, the team continued working on the elaboration of the CIP that will allow the decentralization of Mithril by relying on the Cardano node network layer.

Low level overview​

• Released a new Mithril distribution 2246.1
• Completed the first stage of the store migrations process #562
• Added a Mithril API version that is now exposed in the headers of the requests sent and received by the nodes #565
• Enhanced the explorer UI with epoch settings information and aggregators management on browser local storage #576
• Prepared a Daedalus synchronization benchmark video with/without Mithril #606
• Upgraded the Cardano nodes of the testing Mithril networks to 1.35.4 #594
• Worked on implementing SPO tests nodes on testing Mithril networks #563
• Worked on the CIP design for Mithril piggybacked on the Cardano network layer #588
• Worked on the refactorizaton of the aggregator multi signer engine #398

This sprint, the team has been working on the new continuous integration and delivery (CI/CD) pipelines and the automated deployment of environments as part of the new version of the release process. They also coordinated the migration of the pioneer SPO nodes to these new Mithril networks. They have been implementing the automatic data storage upgrade of the signer and the aggregator nodes. Finally, on the crypto side of things, we've implemented an efficiency improvement on the size of the mithril certificates.
