This week, the Plutus team inspected Plutus behavior on-chain and worked on Plutus Application Backend (PAB) integration. They also made some changes to support the partial transaction format, and restructured the validation benchmarks. Additionally, they worked on regression testing and documentation to support the recent cost parameter changes.

The Marlowe team worked on custom deserialization of Merklization in independent Marlowe semantics. They also discussed processes for ensuring availability of Marlowe deployments, fixed some issues in the Marlowe Playground, and updated Marlowe Run and PAB interfaces. The team updated the Marlowe Run client to reflect the new design of the timeout step and made some additional Haskell types available in the Marlowe Run frontend code to support enhanced error handling.

They continued working on the E2E test diffusion and set up mini-protocol handlers for the testing node: hot chain-sync protocol with full blocks, warm ping-pong protocol, and the keep-alive protocol.

The team finished the refactoring of typed-protocol packages, which now contain the core types including Codec, the typed-protocols-cborg package containing utility functions for writing cborg codecs, typed-protocols-examples containing ping-pong and req-resp protocols, and tests. This is now in review, and once merged, libraries used in the production environment will no longer depend on typed-protocols-examples.
