Quantum Multi-valued Byzantine Agreement Based on d-dimensional Entangled States

Abstract

Byzantine agreement has always been an important research topic of distributed computing and has been widely applied to blockchain technology in recent years. We propose a quantum protocol for solving multi-valued detectable Byzantine agreement problem in this paper. Each general is firstly distributed a list that no one else knows based on d-dimensional entangled states. Then the n generals can reach an agreement in which t (where t
