On-Chain and Off-Chain Collaborative Management System Based on Consortium Blockchain
Abstract
The blockchain system can provide a trust infrastructure for sharing data among untrusted parties. However, storing the original shared data directly on the blockchain is not suitable for large-scale data sharing scenarios. Therefore, we designed a data sharing system architecture in which data hashing and response records are stored on the blockchain and the original data is stored in the off-chain database. This architecture can alleviate the system overload and protect privacy problems to a certain extent. This paper proposes a three-tier system structure to ensure the function of the network. Subsequently, formulate request rules, deploy smart contracts, and build a platform based on the alliance chain. Finally, the system functions and performance are analyzed and compared through experiments. The results show that the system can realize efficient and transparent information sharing while satisfying on-chain and off-chain collaborative management, and the system has certain advantages in function, overall performance and throughput performance.
