High level summary​

The Ledger team has been shifting focus from implementing Conway related features to testing. For this reason there is a very little amount features that are reported this time aorund. Notable Conway related changes are a specialized ledger query for getting Constitutional Committee state and prevention of submitting proposal procedures that have no valid path to enactment.

Testing related work was mainly on a constraint base system as well as on roundtrip serialization. As a result of this extra testing a bug in Conway Genesis serialization was eliminated.

High level overview​

This week, the Mithril team worked on the distribution of the Mithril client as a library that will be distributed on crates.io, the Rust dependencies repository. The team also worked on the deterministic computation of the transaction history of an address from the immutable files and started fixing a bottleneck in the aggregator that limits the ingestion of signatures.

Finally, they kept working on the activation of Cloudflare on the infrastructure and fixed some bugs in the Nix CI.

Low level overview​

  • Worked on the issue Make mithril-client crate a library #1141
  • Worked on the issue Compute deterministic Cardano transactions history PoC #1283
  • Worked on the issue ProtocolKeyRegistration creates performance bottleneck in aggregator #1187
  • Completed the issue Update Rust compiler in nix CI #1282
  • Worked on the issue Mithril networks infrastructure maintenance #1218
  • Worked on the issue Activate Cloudflare protection of infrastructure #1230
