Distributed Randomness using Weighted VRFs

ePrint Report: Distributed Randomness using Weighted VRFs

Sourav Das, Benny Pinkas, Alin Tomescu, Zhuolun Xiang

Generating and integrating shared randomness into a blockchain can expand applications and strengthen security. We aim to have validators generating blockchain randomness autonomously, and fresh shared randomness is generated for each block. We focus on proof-of-stake blockchains, where each validator has a different amount of stake (aka weight). Such chains introduce a weighted threshold setting where subset authorization relies on the cumulative weight of validators …
