Title:
Implementation Study of Two Verifiable Delay Functions
Authors: Vidal Attias, Luigi Vigneri, Vassil Dimitrov
Abstract:Proof of Work is a prevalent mechanism to prove investmentof time in blockchain projects. However the use of massive parallelismand specialized hardware gives an unfair advantage to a small portion ofnodes and raises environmental and economical concerns. In this paperwe provide an implementation study of two Verifiable Delay Functions, anew cryptographic primitive achieving Proof of Work goals in an unpar-allelizable way. We provide simulation results and an optimization basedon a multiexponentiation algorithm.
