This week, the team continued working on the ledger state memory usage and made more in-memory data structure experiments. They also reviewed Cardano DB Sync, made some minor improvements for better performance, and continued working on the separation of the TPraos protocol from the ledger code.

The team fixed some documentation issues with regard to asset names, inspected Windows build issues on GitHub CI, and worked on the Cardano API tests to remove some unnecessary functions and reformat imports.
