Abstract
This paper proposes a simple voting protocol based on Quantum Blockchain. Despite its simplicity, our protocol satisfies the most important properties of secure voting protocols: is anonymous, binding, non-reusable, verifiable, eligible, fair and self-tallying. The protocol could also be implemented using presently available technology.
Highlights
Many voting protocols based on classical cryptography have been developed and successfully applied since Chaum et al [9]

Besides Quantum Blockchain, other quantum techniques used in our protocol include quantum secure communication and quantum bit commitment
Summary
Many voting protocols based on classical cryptography have been developed and successfully applied since Chaum et al [9]. Every voter can verify whether his or her ballot has been counted properly. To the best of our knowledge, among all existing quantum voting protocols, only the protocol proposed by Wang et al [43] satisfies all of the above requirements. Their protocol is difficult to implement using available technology. Our aim, presented in this paper, was to develop a voting protocol that satisfies all of the above requirements, and in addition, can be implemented by presently available technology. There are quantum bit commitment protocols in existence, which are both highly secure and implementable by the current technology.
