Research on Blockchain Consensus Mechanism for Judicial Depository Applications
Shuaiqi Liu, Qingxiao Zheng · 2023
Aiming at the efficiency and security of the blockchain application's consensus mechanism in the judicial depository field, this paper proposes an algorithm that integrates the PoS consensus mechanism based on node credibility with the Bitcoin-NG consensus mechanism. The method improves the security of the consensus algorithm by calculating and rewarding the credibility of nodes based on the improved Cobb-Douglas production function model. Moreover, by enhancing the key block generation algorithm in the Bitcoin-NG consensus mechanism, the consensus time of the blockchain network can be reduced, and the efficiency of the consensus mechanism can be improved. The experimental comparison results show that this improvement scheme can improve the throughput and security of the blockchain system. Applied in the judicial field, this scheme can achieve a credible, secure and efficient judicial depository.
