Addressed a final round of feedback on the ObjectDiffusion mini protocol implementation on ouroboros-network. After implementing some extra integration tests and final touches, this PR is approved and ready to be merged and integrated downstream!
Addressed an initial round of reviews on Peras 18, with a focus on preventing issues caused by invalid parameterizations.
Opened Peras 19, which defines and implements the logic needed to determine when to include a certificate in a block body according to these rules. Notably, our implementation reuses the explainable boolean predicate infrastructure previously developed for the Peras voting rules.
Started working on Peras 20 as continuation of Peras 18. This PR introduces:
- A tiebreaking mechanism to ensure fairness among pools with the same stake when computing a committee selection via weighted Fait-Accompli, and
- Conformance tests between our simplified weighted Fait-Accompli model and the real implementation introduced by Peras 18.
Started working (after several discussions with the Leios team) on a design and implementation plan for cryptographic aggregation of votes into certificates, using BLS-based cryptography as the basis for the upcoming prototype.
