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.

High level overview​

The Mithril team released a new 2315.0 distribution that implements the first part of the migration of the aggregator stores along with minor improvements and bug fixes. They finished the migration of the aggregator stores to a relational design by completing the adaptation and migration of the signed entity, signer and single signature stores. They also created a new tick service that provides beacons to other services of the aggregator. Additionally, they started implementing the new new certifier service of the aggregator that is in charge of producing certificates for multi-signatures.

Finally, they completed the design and definition of the interfaces that must be implemented to provide certification for a new type of data in a Mithril network.

The Mithril team released a new 2313.0 distribution that implements minor improvements and bug fixes. They continued implementing the migration of the aggregator stores to a relational design. They finished adaptating and migrating the certificate, epoch settings, signed entity type, signer registration and open message stores. Additionally, they completed the refactoring of the dependency injector of the aggregator and simplified its multi-signer in order for it to sign multiple concurrent messages.

Finally, the team has worked on designing the new architecture of the network to support signing multiple types of data and upgraded the version of the Cardano node used in the Mithril testnets and devnet to 1.35.6.

High level overview​

The Mithril team released a new 2310.0 distribution that activates the era switch mechanism. They also kept implementing the migration of the aggregator stores to a relational design with the first adaptation of the stake pool store, and then the adaptation of the epoch settings & signed entity type stores. They have implemented the handling of the network API version from the Open API specifications and its automatic switch at era transition. Additionally, they optimized the stake distribution computation that now happens only once per epoch, and also enhanced the client multi-platform workflow to test the Docker images.

Finally, they have successfully completed the tests to create certificates and snapshots on a network running on the Cardano mainnet and they have fixed some bugs.
