High level summary​

The SRE team continues work on cardano environment improvements and general environment maintenance.

Some notable recent updates or improvements include:

  • Work on cardano-parts repo continues and was utilized by the sanchonet-demo repository for demonstration purposes
  • Work on a new capkgs repository started -- "Content Addressed Packages"
    • This repository provides common Cardano release and pre-release binaries in a pure content addressed nix package type via flake output
    • These packages don't have the associated IFD, long eval times and large source dependencies that the originating source repositories often do
    • Consumers of such packages, such as devShells or nixos machines, can benefit from the improved performance this offers
