【Abstract】Referring to the consensus mechanisms of traditional blockchain, a new consensus mechanism of quantum blockchain is designed based on the randomness and the irreversibility of quantum measurement and quantum zero-knowledge proof. This new consensus mechanism does not involve a great deal of computing resources and hence has fewer energy consumption, shorter time delay and higher throughput. Furthermore, the new consensus mechanism could withstand 51% attack.

【摘要】参照传统区块链的共识机制，基于量子测量的随机性和不可逆转性以及量子零知识证明，设计了一种新的量子区块链共识机制。这种新的共识机制不涉及大量的计算资源，因此能源消耗少，时间延迟短，吞吐量大。此外，新的共识机制可以抵御51%的攻击。
