High level overview​

The Mithril team completed the design of the signer deployment model for the SPOs to run Mithril on their Cardano mainnet infrastructure, and implemented the associated Mithril Relay in the Mithril networks. They started working on the design and implementation of a stress test tool for benchmarking the aggregator performances. They worked on the refactoring of the Mithril Stake Distribution entity and the uniformization of the date types in the nodes. They also worked on implementing a new tool command in the aggregator and its first sub-command that helps avoiding re-genesis of the certificate chain when the structure of the certificate is updated. Additionally, they worked on implementing some monitoring for the Mithril infrastructure, and worked on a retry mechanism for the artifact creation of the aggregator.

Finally, they fixed some bugs, and they completed the upgrade of the Mithril networks to Cardano node v.8.1.1.

High level overview​

The Mithril team completed the implementation of the new sub-command for restoring a Mithril stake distribution in the client. They also updated the client’s developer documentation and architecture documentation, and did some refactoring on the client and its dependency injection mechanism. Additionally, they completed and deployed infrastructure enhancements on the test Mithril networks. They also completed the performance tests of the new stake distribution computation on the Cardano mainnet.

Finally, the team worked on fixing a bug on the client multi-platform test, a bug on the aggregator state machine, and some flakiness on the CI.

High level overview​

The Mithril team released a new 2321.1 distribution that fully implements the mechanism developed to sign generic data. They completed the upgrade of the Cardano node in the Mithril networks to v.8.0.0 and the implementation of the new computation of the stake distribution. They refactored the state machines of the signer and aggregator, and the signed entity service of the aggregator. Additionally, they worked on adapting the client and implementing a new sub-command for restoring the Cardano immutable file snapshots.

Finally, the team worked on adding a new certificate list route in the aggregator REST API, and started enhancing the infrastructure of the Mithril networks.

High level overview​

The Mithril team released a new 2318.0 distribution that implements the last migration phase of the aggregator stores and embeds a bug fix for the signer registration. They also completed the implementation of the interfaces defined to provide certification for the immutable full snapshot of Cardano files and Mithril stake distribution. They finalized the implementation of the framework to sign generic types of data in the aggregator and the signer nodes. They also updated the runtime of the aggregator to handle open messages associated with the available types, and evolved the REST API of the aggregator to deliver the artifacts for these types. Additionally, they have upgraded the network explorer in order to display the artifacts and certificates for these different types.

Finally, the team started designing an on-chain decentralized signer registration process, and started implementing the new stake distribution computation available from Cardano node 8.0.0 (along with the backward compatibility for previous 1.35.x versions).

High level overview​

The Mithril team completed the implementation of the new certifier service of the aggregator, which is in charge of producing certificates for multi-signatures. They also finished implementing the interfaces defined to provide certification for the full immutable Cardano files snapshot and the Mithril stake distribution. Additionally, they have completed the refactoring of the multi-signer in the aggregator. The team also fixed the bug in the signer registration that was responsible for gaps during the signature phase for some signers, and they upgraded the Cardano node used in the Mithril testnets and devnet to version 1.35.7.

Finally, they have worked on designing a decentralized registration for the signers that takes place on the Cardano chain.
