Hydra Team Update

· 2 min read

High-level summary​

This week, the Hydra team worked on aligning the specification with the current incremental decommit implementation, added decommit to model-based tests and also discussed the incremental commit protocol extension with researchers. The team also updated to cardano-api 8.40 and tests against cardano-node 8.9.0, which unblocked a possible release and re-enabled smoke tests on public networks. They also groomed a new /commit endpoint interface from a user discussion and discussed restructuring of the Hydra documentation. The team also prepared a Conway-supporting hydra-node on branch lc/conway-support for early adopters (Hi @Juantxu and @ash 👋). Some internal refactoring prepared for upcoming streaming plugins by SundaeLabs and minor fixes to the TUI and hydra-explorer rounded off the week.
