Ouroboros Peras

This week we:

  • Completed the initial plumbing needed for Peras to be supported by the HardFork Combinator. More concretely, this change splits the existing global Peras impementation so that:

    • Production code can be instantiated with real, cryptographically-signed votes and certificates, and
    • Test code can still used mocked values without crypto.

  • Addressed the new feedback we received for the open PRs (Peras 24, 25, 25.5, and 26).

  • Made progress with the Peras Testnet, having sucessfully built the latest version of the Peras code in ouroboros-consensus after manually integrating it into cardano-node. From here, it should be straightforward to continue porting new Peras changes incrementally as they come.
