How hard are verifiable delay functions?

Cryptography and Security 2022-11-16 v1

Abstract

Verifiable delay functions (VDF) are functions that take a specified number of sequential steps to be evaluated but can be verified efficiently. In this paper, we introduce a new complexity class that contains all the VDFs. We show that this new class VDF\mathbf{VDF} is a subclass of CLS\mathbf{CLS} (continuous local search) and Relaxed-Sink-of-Verifiable-Line is a complete problem for the class VDF\mathbf{VDF}.
