High-level summary​

This week, the Hydra team made significant progress on incremental decommits by closing the last gaps and cleaning up the specification. They collected scenarios and prepared for incremental commits, updated dependencies for compatibility with cardano-node 9.0.0, and continued tidying up documentation. Work continued on an easy spin-up of the getting-started demo via process-compose. Additionally, the team onboarded a new contributor and held an early design meeting about payment channels and Blockfrost. They also refined the SDK wallet idea.

What did the team achieve?​

  • Incremental decommit progress: closed last gaps, cleanup specification #1483
  • Collected scenarios and preparing for incremental commit #1484
  • Updated dependencies, compatibility cardano-node 9.0.0 #1481

High level summary​

While we are waiting for Chang hard fork we are focusing on as much testing as possible. Therefore all work that was done mostly related to writing unit tests and conformance testing.

High level overview​

This week, the Mithril team released the new distribution 2428.0, which includes support for Cardano node version 9.0.0, as well as bug fixes and optimizations. They also continued implementing the certification of Cardano transactions in Mithril networks by calibrating the signature parameters for mainnet, fixing a bug preventing the signature of the last block advertised as certified, optimizing a part of the artifact production that was blocking the certification, and starting removing the code reading transactions from the immutable files.

Finally, the team started working on the certification of the Cardano stake distribution and continued redacting a CIP for the diffusion of Mithril signatures through the Cardano network.
