Distributed Randomness Beacons

Joseph Bonneau

8.22.23

Distributed randomness beacons enable a group of participants to create a common, public, random value, even in the presence of some dishonest participants. Applications include lotteries and gaming, consensus protocols, fair transaction ordering, election audits, and even zero-knowledge proofs. They have attracted particular attention in the cryptocurrency space. Joe Bonneau (a16z crypto) presents a high-level survey of approaches to building distributed randomness beacon protocols, based on the Systematization of Knowledge (SoK) published at IEEE Security and Privacy 2023.
