Peras Design

  • Received confirmation from the TSC that using BLS cryptography alongside an increased quorum threshold is the preferred approach for now.

Consensus

  • Prepared and merged Peras PRs #75, #76 and #77.
  • Continued work on deriving Peras parameters from Ledger protocol parameters and static configuration parameters, including the security parameter k and active slot coefficient f. This also provided an opportunity to simplify the interface around context resolution and ticking.
  • Fixed a bug in voting power distribution among non-persistent voters.
  • Started work on integrating Peras weights into the GDD.

Network

  • Addressed feedback in the Network PR, which is now awaiting approval. Peras PRs #71 and #72 are ready for integration.
  • Started preparing testnet experiments.
  • The final internal PR is ready for review.

Testnet

  • Bootstrapped cardano-kosmos, now the preferred testnet setup option.
  • Added Grafana with dashboard visualisations from cardano-ignite.
  • Fixed process-compose cleanup routines.
  • Added a CI check that runs the testnet until Peras works.
  • Implemented a new version of stake redistribution.
  • Implemented an initial draft of Peras visualisation.
  • Updated test scripts checking Peras traces to validate expected behaviour under broader conditions.
