High level summary​

  • Leios prototype development (Treasury Funding Initiative 4: Ouroboros Leios Implementation):
    • Completed the migration of endorser-block announcements and certification flags from the Ledger Block into the Praos Header, aligning the prototype with the original Leios design (#1978, ouroboros-leios#874, cardano-node#6537).
    • Fixed several bugs in the Leios prototype (#2017).
    • Helped the SRE team stand up a Leios testnet that is now running the prototype (ouroboros-leios#879).
    • Working on the voting prototype (#1963).
    • Continuing to investigate and fix in-memory LeiosDb performance issues observed during the March demo (ouroboros-leios#844, cardano-node#6554).
    • Working on applying Certified Endorser Blocks to the Mempool (ouroboros-leios#838).
  • Ledger-HD (Treasury Funding Initiative 11: Ledger-HD):
    • Refactored consensus type variables so that ledger tables, transaction inputs, and transaction outputs are indexed by the block type rather than the ledger-state shape, collapsing duplicate type-class instances and simplifying the codebase ahead of Ledger-HD integration (#2016, #2019).
  • Releases and integration (Treasury Funding Initiative 17: Maintenance and Support):
  • Documentation (Treasury Funding Initiative 17: Maintenance and Support):
    • Added an explanation page covering the Ticking mechanism used by the consensus layer (#2011).
