High-level summary​

This week, the Hydra team worked on multiple fronts. They finished the investigation about the broken head on mainnet and re-opened their persistent head instance. The team also fixed the monthly report publication on their website and started sketching ideas and further improvements. Also, they are on the last mile to deliver a new feature which will allow parties to commit funds from extern wallets. Finally the team started to work on optimizing the performance on their benchmarks.

What did the team achieve this week​

  • Finished investigation on broken head on mainnet #897 and re-opened it.
  • Added support for externally committing regular utxo #887
  • Fix monthly report publication on docs website and published the monthly report. Odd problems when publishing monthly report:
    • Make us think about if we should change something about the website #908
    • Open issue to docusaurus #9036
  • Fixed a bug in the benchmark process #910
  • Explored performance of the hydra-node{.verbatim} and identified a bottleneck.
  • Timed transaction feature is being used by the auction project 🎉

What are the goals of next week​

  • Complete performance analysis and start/plan improvements and provide regular benchmarks for Hydra #186
  • Add hydra as tool to developer platform #872.
  • Authenticate network messages #727.
  • Complete journey for external commits using multiple script UTxOs #903
  • Start implementing Option B for external commits #215.

High-level summary​

This week, the Hydra team has put their effort on finding solutions on many different problems, such as our broken head on mainnet #897, our fragile monthly report publications on the website and implementing “Option A” for external commits #215. Although most of these items are still open, huge progress has been made. To accelerate the investigation, they improved their logging to give more precise errors when a transition requirement fails, and to reduce duplication on effets logged content. Last but not least, the team is exploring formal methods and attended a workshop on formalizing cryptographic protocols in Agda.

What did the team achieve this week​

  • Continued investigating broken head and opened an issue to keep track #897.

    As part of this issue, improvements were made to the node logs:

    • Give a precise error when a transition requirement fails #895.

    • Reduce duplication for effects logged content by using sequential eventId and effectId pair #896.

  • Fixed references in the hydra specification #893.

  • Attended a workshop on formal methods and crypto in Agda.

What are the goals of next week​

  • Investigate and re-open our team-internal head on mainnet.
  • Improve and provide regular benchmarks for Hydra #186.
  • Complete journey for external commits implementing “Option A” and start implementing “Option B” #215.
  • Authenticate network messages #727.
  • Add hydra as tool to developr platform #872.
  • Fix monthly report publication on docs website.

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.

What did the team achieve this week​

  • Held the monthly review meeting (recording + slides) & drafted the report for May.
  • Have a first end-to-end journey for external commits implementing “Option A” for normal UTxOs #887 (still considering “Option B”).
  • Integrated the spanish translation #866.
  • Created micro-benchmarks for transaction validation and deserialization #884.
  • Improve hydra-node –version reporting on non-released builds #849
  • Some minor CI improvements following up last weeks changes.
  • Allow commit transactions with multiple UTxO #774.

What are the goals of next week​

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.
