Powers-of-Tau to the People: Decentralizing Setup Ceremonies

Authors: Valeria Nikolaenko, Sam Ragsdale, Joseph Bonneau, Dan Boneh


We introduce the first decentralized trusted setup protocols for constructing a powers-of-tau structured reference string. Facilitated by a blockchain platform, our protocols can run in a permissionless manner, with anybody able to participate in exchange for paying requisite transaction fees. The result is secure as long as any single party participates honestly. We introduce several protocols optimized for different sized powers-of-tau setups and using an on-chain or off-chain data availability model to store the resulting string. We implement our most efficient protocol on top of Ethereum, demonstrating practical concrete performance numbers.
