High-level Summary​

The team made good progress this week, with the release of version 0.15.0 marking a milestone, along with the monthly review including both Mithril and Hydra work. We addressed issues in smoke tests and website publishing workflows, ensuring a more robust development environment, and along the way included more "dogfooding" through the use of Mithril to synchronize nodes in smoke tests.

What did the team achieve this week​

  • Release of Version 0.15.0. This release enhances the overall stability and functionality of our product.
  • Monthly Review and Community Demos
  • Smoke Tests and Website Publishing Workflow Fixes: #1246
    • Resolved glitches in the website publishing workflows, enhancing the efficiency of our deployment processes.
  • Integration of Mithril for Smoke Test Synchronization: #1252
  • Polishing of Hydra-Chess v0.1.0: #1237
    • Worked on polishing hydra-chess v0.1.0, treating it as an example application running on Hydra. This not only demonstrates the capabilities of our platform but also aims at providing a reference for future Hydra developers.

What are the goals of next week​

  • Merge Off-Chain Protocol Logic for incremental decommits
  • Initiate work on the on-chain portion of incremental decommits
  • Merge CBOR API Change #1240
  • Troubleshoot Dangling Fanout Issue #1260

Some notable recent changes, updates or improvements include:

  • Cardano-node 8.7.3 is now generally deployed to all testnet and mainnet environments managed by coretech SRE

  • Dbsync and node stack process-compose jobs are now available from cardano-parts for users running nix >= 2.17.0 and nix experimental-features = nix-command flakes fetch-closure

  • These can be run with:

     nix run github:input-output-hk/cardano-parts#run-process-compose-node-stack
     nix run github:input-output-hk/cardano-parts#run-process-compose-dbsync-$NETWORK

High level overview​

This week, the Mithril team completed the implementation of the client in the explorer, enabling direct certificate verification from the browser. They initiated the implementation of a new entity type for signing to certify the Cardano transactions set in Mithril networks. The team also upgraded the devnet to support the Conway era and activated the Mithril era marker reader on the Cardano chain in the end-to-end test. Additionally, they kept implementing a mock aggregator to strengthen Mithril client tests in WASM and continued working on threat modeling and risk analysis for P2P networking.

Finally, they worked on enhancing node communications between Mithril and Cardano, and they started rolling out the Cardano node in the infrastructure to version 8.7.3.
