Implementation Study of Two Verifiable Delay Functions

Abstract

Proof of Work is a prevalent mechanism to prove investment of time in blockchain projects. However, the use of massive parallelism and specialized hardware gives an unfair advantage to a small portion of nodes and raises environmental and economical concerns. In this paper, we provide an implementation study of two Verifiable Delay Functions, a new cryptographic primitive achieving Proof of Work goals in an unparallelizable way. We provide simulation results and an optimization based on a multiexponentiation algorithm.
