Design and analysis of quantum detectable Byzantine protocol based on numerical list distribution
Quantum technology can empower blockchain technology and improve the security performance of the blockchain consensus protocol.According to whether there is an honest independent quantum source device(QSD),we propose two numerical list distribution methods with high success rate for multiple nodes,and further propose a new quantum detection Byzantine protocol based on numerical list distribution.A consensus example of four nodes verifies that the proposed protocol meets the conditions for detecting Byzantine protocols.Finally,through analysis and comparison,the proposed protocol has better practicability and security.Compared with other protocols,the consensus protocol proposed in this paper can not only solve the problem of multi-bit data consensus in the blockchain system containing multiple nodes,but also deal with the attack of any number of malicious nodes during the consensus process,which improves the security of the blockchain system.
