Randomness Beacons in Theory and Practice

Explore a 21-minute talk from Real World Crypto (RWC) 2025 where Joseph Bonneau discusses the theoretical foundations and practical applications of randomness beacons. This presentation was the opening talk in the Distributed Trust session chaired by Lenka Marekova. Gain insights into how randomness beacons function, their security properties, and their real-world implementations in cryptographic systems. The talk addresses both the theoretical underpinnings and practical challenges of deploying reliable sources of public randomness.
