Introducing Ouroboros Phalanx – breaking the economics of grinding attacks
Phalanx aims to enhance Ouroboros with stronger randomness generation, preventing grinding attacks and delivering faster, more reliable transaction settlement
22 October 2025 9 mins read
Summary:
- Ouroboros Phalanx strengthens Cardano’s consensus foundation by addressing a subtle but important vulnerability in randomness generation known as grinding attacks
- By introducing verifiable delay functions (VDFs) and extending how randomness is built across epochs, Phalanx makes such attacks exponentially more costly and practically infeasible
- This upgrade not only…
Unlocking zero-knowledge proofs for Cardano: the Halo2-Plutus verifier
Learn about an open-source prototype bringing zero-knowledge proofs to Cardano for private, scalable, and interoperable applications
