摘要
在跨组织的数据共享与交换中,维护较强的操作一致性是实现有效的数据同步的重要技术保障.以区块链技术为基础,提出了一种提高跨组织数据交换操作一致性性能的模型,将联盟链作为写前日志,供数据库回溯未完成同步的数据,在联盟链中增设了指针结构,以降低回溯时长.同时,设计了链上存储请求的数据结构及共识算法,通过设置准入机制验证用户身份,保护数据安全以及用户隐私.最后通过仿真实验验证所提模型的有效性,并探讨了不同参数对相关性能指标的影响.结果表明,在不同的参数设定下,所提模型均能保障跨组织数据交换过程中的强一致性;且与基准模型相比,具有更高的请求执行效率;当链上数据量较大时,指针结构能够进一步提升模型性能.
Abstract
In the context of inter-organizational data sharing and exchange,maintaining strong operational consistency is a crucial technical foundation to achieve effective data synchronization.Based on blockchain technology,a model to enhance the operational consistency for inter-organizational data exchange is proposed.The model leverages a consortium blockchain as a write-ahead log,enabling databases to backtrack incomplete synchronizations.Within the consortium blockchain,a pointer structure is implemen-ted to reduce the time required for backtracking.Additionally,data structures and consensus algorithms are designed for on-chain storage of requests.An access control mechanism is set up to verify user identities,ensuring data security and user privacy.Final-ly,simulation experiments are conducted to validate the reliability of the proposed model and explore the impact of a series of pa-rameters on different evaluation metrics.The results indicate that under various parameter settings,the proposed model ensures strong operational consistency for inter-organizational data exchange.Furthermore,compared to existing baselines,it exhibits higher request execution efficiency.Moreover,the pointer structure further enhances the model's performance,especially when there is a large amount of data stored on the chain.
