Title:
MinRoot: Candidate Sequential Function for Ethereum VDF

Authors: Dmitry Khovratovich, Mary Maller, Pratyush Ranjan Tiwari

Abstract:

We present a candidate sequential function for a VDF protocol to be used within the Ethereum ecosystem. The new function, called MinRoot, is an optimized iterative algebraic transformation and is a strict improvement over competitors VeeDo and Sloth++. We analyze various attacks on sequentiality and suggest weakened versions for public scrutiny. We also announce bounties on certain research directions in cryptanalysis.
