(R)Icy-DVRF: A Robust Distributed Verifiable Random Function based on ROAST signatures
, AYWARE, Middle East Technical University, Middle East Technical UniversityAbstract
Ensuring robustness and liveness in distributed verifiable random functions (DVRFs) allows the protocol to maintain correct operation and guarantee output generation, even in the presence of malicious actors attempting to disrupt the process, delay cryptographic shares, or remain unresponsive. Because existing DVRF protocols typically rely on synchronous or semi-synchronous network assumptions, simultaneously achieving these properties remains a challenge. To address this limitation, this paper enhances the FROST-based Icy-DVRF protocol to achieve both robustness and liveness. Specifically, we propose (R)Icy-DVRF, a novel protocol that operates over an asynchronous network while maintaining a constant-size proof. This is achieved by integrating the ROAST wrapper framework into the underlying threshold signature mechanism.
