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.

High level overview

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.

High level overview

The Mithril team worked on deploying the era activation mechanism to their test networks and preparing the upgrade procedure to be implemented on the signer nodes run by the SPOs. They also refactored the state machines of the aggregator and signer nodes so that they can better handle critical errors, which lead to node panic, from recoverable errors. Additionally, the team continued the deployment of a new test network that runs on the Cardano mainnet and computes the stake distribution with the optimized unreleased Cardano CLI command.

Finally, they have designed the certification of generic types of data by a Mithril network and they have started implementing its first phase. Also they fixed a bug that made the client Docker image crash at startup.

High level overview

The Mithril team released a new 2306.0 distribution that implements minor fixes and updates and completes the wiring of the era activation markers reader into the signer and aggregator nodes. They also designed an event store in the aggregator and completed its implementation as a monitoring solution to provide figures for deployment rates of versions on signer nodes before activating an era switch. Additionally, the team created a dedicated command on their nodes’ CLI that allows generating and signing an era marker’s payload to be stored on the Cardano chain, as well as creating dynamic cases for the end-to-end tests they run on the CI.
