High level summary​

The SRE team continues work on cardano environment improvements and general environment maintenance.

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

  • For more details, see the merged cardano-parts process-compose PR

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.

High-level summary​

This week, the Hydra team improved Github actions workflows, addressed protocol parameter schema consistency in hydra-node, and made enhancements to log schema tests. They created an Architectural Decision Record (ADR) for Cardano transactions serialization in APIs, moved the hydra-chess project to a dedicated repository, and resolved a bug in quickcheck-dynamic and model tests.

There will be the monthly review meeting with demos on Hydra, Mithril and related projects. If this sounds interesting, join us in Google Meet https://meet.google.com/udc-zgyw-agd next week, January 19 2024 at 17:30 UTC.

What did the team achieve this week​

  • Github actions improvements and small fixes to the smoke tests #1242, #1233
  • Fixed protocol parameter schema consistency around hydra-node #1234
  • Log schema tests improvements and fixes #1244
  • Created ADR about Cardano transactions serialisation in our APIs #1215
  • Moved hydra-chess #1237 to a dedicated cardano-scaling organisation repository https://github.com/cardano-scaling/hydra-chess
  • Identified bug on quickcheck-dynamic / our model tests #1239

What are the goals of next week​

  • Monthly review meeting (January 19, 17:30 UTC) including several demos (from team and contributors)
  • Do release 0.15.0
  • Improve quickcheck-dynamic model to be more robust and cover more behaviour.
  • Draft POC about backend for a hydra-explorer that can track all heads on-chain.
