High-level summary​

This week, the Hydra team accomplished several important tasks. They held their monthly review meeting and drafted the report for May. They made progress on implementing the first end-to-end journey for external commits using "Option A" for normal UTxOs, while still considering "Option B". The team also integrated a Spanish translation contributed by the community, created micro-benchmarks for transaction validation and deserialization, and made improvements to hydra-node's version reporting. Last but not least, they implemented the ability to commit multiple UTxOs to a head at once.

High level summary​

The ledger team made progress on the conway ledger era. In particular, the design and implementation of the new certificates is near complete, we refactored some of our data structures to be able to support DReps, we cleaned up the serialization format, and renamed things to make clearer the differences with Shelley.

The team also completed integration work for the next node release, namely 8.1.0. And, as always, we continue to address technical debt.

High level summary​

  • The last sprint focused on removing cardano-cli and cardano-api from the cardano-node repository. We have successfully moved cardano-api to its own repository and will do the same for cardano-cli after the 8.1 node is released.
  • We provided assitance where needed in the release
  • An integration repository https://github.com/input-output-hk/fusion-flamingo was created to enable my team to more easily work on cardano-cli and cardano-api
