High-level summary​

This week, the Hydra team released version 0.8.1, which includes several fixes and a user-wished extension of the persistence introduced by 0.8.0 of replaying server outputs to make clients like the hydra-tui be aware of the latest hydra-node state. The team also worked on the specification and closing gaps in the on-chain scripts, collaborated with the education team on a Hydra tutorial and also renamed the repository from hydra-poc to hydra!

What did the team achieve this week​

  • Implemented replaying of server outputs to address #580
  • Released version 0.8.1 containing this and other fixes Release notes
  • Worked on the bounded tx validity as one of the on-chain script fixes, but couldn’t finish it just yet #615
  • Collaborated with the education team on a Hydra tutorial.
  • Discovered and discussed issues with the “seen ledger”.
  • Renamed the Hydra repository hydra-poc -> hydra

What are the goals of next week​

  • Create and discuss an ADR about handling tx validity correctly.
  • Attend the Cardano Summit in Lausanne. Hydra will be topic of one talk! Save the date+time: "Developing Hydra" on Day 2, Nov 21st, 13:50 CET
  • Have a team workshop / hackathon after the summit:
    • Retrospective
    • Roadmapping session
    • Hack on something complex or useful

High-level summary​

This week, the Hydra team published together with Obsidian Systems a light paper on our "Hydra for Payments" project (Link). They have created a draft scope RFP for the external audit and worked with the internal audit team to clear up the specification. From the development side, they have fixed a bug with chain-following when using persistence and improved logs for better observability of hydra-node processes.

What did the team achieve this week​

  • Published Hydra for Payments light paper (Link)
  • Have a draft RFP ready for a first review internally
  • Answered the internal auditor’s questions
  • Fixed a bug with following the chain when starting with persistence (#599)
  • Minor improvements to logging for better observability (#598, #600)
  • Non-achievement: Needed to work around flaky TUI ci, follow-up issue if anyone wants to have a look (#590)

What are the goals of next week​

  • Implement event-sourced persistence #580
  • Close more gaps #452
  • Attend the Cardano Summit in Lausanne. Hydra will be topic of one talk! Save the date+time: "Developing Hydra" on Day 2, Nov 21st, 13:50 CET
