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.

This week, the Hydra team has worked on several fronts, including improvements of their CI speed, logs, documentation pages and adding the support for timed transactions. They also updated the "Coding Standards" for the project, improved the troubleshooting page on their website and wrote a section about how to operate a hydra node. Finally the team completed a feature request that allows clients to submit and validate transactions to their hydra nodes using time validity ranges, ensuring isomorphism with L1.

  • Complete validation of timed transactions feature #196.
  • Write “ops” instructions and troubleshooting #569 and improve logs.
  • Remove --ledger-genesis argument to hydra-node options #863.
  • Fix issue with garbage collected caches by using a new cardano-scaling.cachix in more workflows #877.
  • Use nix to build test binaries to increase CI speed #867.
  • Updated our Coding Standards.

What are the goals of next week​

  • Monthly report & review meeting.

High-level summary​

This week, the Hydra team worked on several fronts, including fixing state machine continuity on-chain, discussing voting project solutions, exploring adding Hydra support to kupo, and improving API navigation with a sidebar. The team also updated dependencies and fixed issues in their test suites. Moving forward, the team plans to hold the next monthly review meeting, address a user issue, prepare for the 0.10.0 release, and work on a dirt road fix for the rollbacks issue with proper test coverage.

What did the team achieve this week​

  • Fixed scripts to enforce state machine continuity on-chain #777.
  • Took part in a twitter space on “Scaling Cardano”.
  • Joined a CBIA meeting to discuss Cardano network protocols & how to specify them.
  • Discussed potential solutions of ensuring vote uniqueness in the voting project.
  • Updated dependencies to match cardano-node master to prepare for upcoming releases and hard-forks
  • Explored adding Hydra support to kupo, a lightweight Cardano chain indexer - some more work required.
  • Improved navigation of the API Reference with a sidebar, see unstable API version.
  • Fixed two things in our test suites (random port conflicts and an arithmetic underflow in smoke test)

What are the goals of next week​

  • Monthly review meeting (join via Discord or AddEvent) & report
  • Dirt road fix for rollbacks #784 properly covered by a test.
  • Groom and ideally address user issue #823.
