High-level summary​

This week the team focused on exploring the event sourced persistence in order to improve hydra-node performance. Because of this work the team noticed we need to refactor the emit snapshot emission logic and update the spec in the light of new changes. They also took the time to revisit their goals and product plans for the next quarter as well as doing some security fixes related to multisignatures.

What did the team achieve this week​

  • Finished spike about performance improvements of event sourced persistence #963.
  • Refactor snapshot emission in protocol logic.
  • Revisited our roadmap and goals.
  • Prepared and conducated a learning session on lean-waste.
  • Improve security of multi-signature checks, see this Github security advisory.
  • Implemented a cache friendly way to version our binaries #962.

What are the goals of next week​

  • Implement Event sourced persistence #913.
  • Remove deprecated internal commit #954 and close #728.

High-level summary​

This week the Hydra team accomplished some nice progress. They secured the network layer further by implementing authentication of the messages between the peers in the Head protocol. In the process they also managed to separate HeartBeat messages from the protocol ones which somewhat improved the quality of code in Hydra. The team also finished work related to sending only transaction ids in ReqSn messages, fixed an issue in the smoke tests, and improved benchmark publishing on the website.

They also listed Hydra as a tool on the Cardano developer portal, providing more visibility for the project. The team clarified the path forward for L2 protocol improvements and explored an alternative CI approach using cabal instead of nix. Additionally, they released version 0.11.0, marking another milestone in the project’s development.
