Operational Consistency Model Based on Consortium Blockchain for Inter-organizational Data Exchange
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.
