为实现更高效、更安全的数据共享,文章提出基于混合共识优化的区块链安全数据共享技术,通过权益证明(Proof of Stake,PoS)选举出一部分验证节点,然后采用拜占庭容错(Practical By-zantine Fault Tolerance,PBFT)算法达成共识.最后,研究将数据加密和共识算法相结合,设计出一种区块链安全数据共享方案.数据显示,在节点数量为120时,PBFT的交易时延为19ms,混合共识优化算法的交易时延为3ms.当并行事务数达到1000时,每秒事务执行量平均值为40.结果表明,研究提出的混合共识优化算法和区块链安全数据共享方案在提高区块链网络性能和能源效率、保障数据安全性和隐私保护方面具有一定的优势和可行性.
Application of Blockchain Security Data Sharing Technology Based on Hy-brid Consensus Optimization
To achieve more efficient and secure data sharing,a blockchain secure data sharing technology based on hybrid consensus optimization is proposed.A portion of verification nodes are selected through Proof of Stake(PoS),and then consensus is reached using the Practical By-zantine Fault Tolerance(PBFT)algorithm.Finally,the study combines data encryption and con-sensus algorithms to design a blockchain secure data sharing scheme.The data shows that when the number of nodes is 120,the transaction delay of PBFT is 19ms,and the transaction delay of the mixed consensus optimization algorithm is 3ms.When the number of parallel transactions reaches 1000,the average transaction execution rate per second is 40.The results indicate that the hybrid consensus optimization algorithm and blockchain security data sharing scheme proposed in the study have certain advantages and feasibility in improving blockchain network perform-ance and energy efficiency,ensuring data security and privacy protection.
