【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 < n/3) of them are disloyal by using these lists. Finally, it is proved that the list distribution process is secure, and the proposed protocol satisfies the definition of the multi-valued detectable Byzantine agreement.
