Title:
Fast SNARK-based Non-Interactive Distributed Verifiable Random Function with Ethereum Compatibility
Authors: Jia Liu, Mark Manulis
Abstract:Distributed randomness beacons (DRBs) are fundamental for various decentralised applications, such as consensus protocols, decentralised gaming and lotteries, and collective governance protocols. These applications are heavily used on modern blockchain platforms.
This paper presents the so far most efficient direct construction and implementation of a non-interactive distributed verifiable random function (NI-DVRF) that is fully compatible with Ethereum. Our NI-DVRF scheme adopts pairings and combines techniques from secret sharing, SNARKs, and BLS signatures.
The security properties of the resulting NI-DVRF scheme are formally modelled and proven in the random oracle model under standard pairing-based assumptions.
To justify the efficiency and cost claims and more generally its adoption potential in practice, the proposed NI-DVRF scheme was implemented in Rust and Solidity. Our NI-DVRF implementation is highly optimised and is currently being investigated for deployment on the multichain layer-2 scaling solution provided by Boba Network to power its DRB service. Our experimental analysis, therefore, also evaluates performance and scalability properties of the proposed NI-DVRF and its implementation.
