High level overview​

The Mithril team released a new 2304.1 distribution that enables the backward/forward compatibility mechanism implemented for seamlessly rolling out soft updates to Mithril networks. They completed the implementation of the era reader trait that powers the era switch behavior. The team finalized the development of the era reader adapter that retrieves era activation markers from transactions on the Cardano chain. They also completed the relational design of the aggregator store.

Finally, they created new SPO nodes on the Mithril networks and upgraded the Cardano node to version 1.35.5 on their devnet and infrastructure.

High level overview​

The Mithril team released a new 2302.0 distribution that activates the optimization of the snapshot digest computation on the signer and aggregator nodes. They have implemented a backward/forward compatibility mechanism for handling seamless soft updates of the Mithril networks without using synchronous updates when possible. The team also worked on the proof of concept to rely on an on-chain transaction to synchronously trigger the era switch of all the signer and aggregator nodes.

Finally, they finished upgrading the devnet, fixed the flakiness issues in the end-to-end tests of the CI, and upgraded the SPO documentation to set up a Mithril signer node.

High level overview​

The Mithril team has been designing a mechanism for handling seamless updates of the Mithril networks in case of breaking-changes that require synchronous update of the signer nodes. This design has been formalized in an ADR. They have been working on an implementation of a proof of concept to rely on an on-chain transaction to synchronously trigger the version switch of all the signer nodes. They have also worked on implementing prototype solutions to minimize the use of breaking changes where soft updates are possible.

Finally, they have worked on upgrading the devnet and fixing some flakiness in the end to end tests of the CI.

Low level overview​

  • Implemented the redaction of an ADR for handling graceful updates of the Mithril Network #671
  • Worked on a proof of concept to handle backward compatibilty of exchanged messages with protobuf #677
  • Worked on a proof of concept to handle backward compatibilty of exchanged messages with avro #678
  • Worked on a proof of concept for reading/writing era activation markers with a Cardano chain transaction #672
  • Worked on upgrading the Cardano node of the Mithril devnet, as well as fixing flakiness of the CI #523
  • Prepared and tested the new 2302 distribution pre-release 2302.0-prerelease
  • Updated the documentation for SPO to build a signer node in order to better reflect the new release process #681

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.

Low level overview​

  • Implemented removing verification key and stake from single signatures #619
  • Completed the extraction of the signer registration from the multi-signer #642
  • Completed the extraction of the certificate creation from the multi-signer #638
  • Implemented a workflow to test client binaries (Linux / MacOS / Windows) #601
  • Completed the signature of the artifacts produced by the CI #587
  • Fixed the protocol parameters transition #627
  • Worked on optimizing the snapshot digest computation #510
  • Worked on enforcing the API protocol versions in the client and signer #633
  • Worked on deactivating the non certified signer registration mode #621
  • Worked on the re-genesis of the test networks #651

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
