High-level Summary​

This week, the team made finally progress on the model based testing framework (and reproducing a bug) by fixing issues related to fully validating Cardano transactions. They also enabled continuous deployment of hydra-explorer to http://explorer.hydra.family/heads, facilitating easier access for users. Furthermore, they improved code quality by incorporating Haskell linting into their CI workflow and addeda user-ished conversion of HeadId to CurrencySymbol.

What did the team achieve this week​

  • Fixed model based testing framework to fully validate Cardano transactions
  • Enabled continuous deployment of hydra-explorer to http://explorer.hydra.family/heads
  • Identified need for cardano-node 8.8 and cardano-api 8.38 (breaking changes) to continue integration with Conway networks
  • Added Haskell linting to our CI workflow - Minor addition to convert HeadId into CurrencySymbol #919
  • Reviewed a small refactor PR on our model-based test runner #1300

What are the goals of next week​

  • Fix the fanout after contest bug
  • Bite the bullet and have a non-mainnet compatible master to complete smoke tests on sanchonet
  • Specify the on-chain validators for incremental decommits

What did the team achieve this week​

  • Conducted yearly roadmapping sessions
  • Merged a breaking API change to drop JSON encoding of transactions #1213 - contact us if you were relying on this.
  • Completed off-chain logic for incremental decommits #1223
  • Implemented a hydra-explorer backend #1235

What are the goals of next week​

  • Publish the monthly report
  • Prepare PRs for hydra clients to switch to CBOR due to the changed API (see above)

High-level Summary​

The team made good progress this week, with the release of version 0.15.0 marking a milestone, along with the monthly review including both Mithril and Hydra work. We addressed issues in smoke tests and website publishing workflows, ensuring a more robust development environment, and along the way included more "dogfooding" through the use of Mithril to synchronize nodes in smoke tests.

What did the team achieve this week​

  • Release of Version 0.15.0. This release enhances the overall stability and functionality of our product.
  • Monthly Review and Community Demos
  • Smoke Tests and Website Publishing Workflow Fixes: #1246
    • Resolved glitches in the website publishing workflows, enhancing the efficiency of our deployment processes.
  • Integration of Mithril for Smoke Test Synchronization: #1252
  • Polishing of Hydra-Chess v0.1.0: #1237
    • Worked on polishing hydra-chess v0.1.0, treating it as an example application running on Hydra. This not only demonstrates the capabilities of our platform but also aims at providing a reference for future Hydra developers.

What are the goals of next week​

  • Merge Off-Chain Protocol Logic for incremental decommits
  • Initiate work on the on-chain portion of incremental decommits
  • Merge CBOR API Change #1240
  • Troubleshoot Dangling Fanout Issue #1260
