Blockchain-based data sharing method for multi-value chain collaboration

To solve the problems of inconsistent description of data, existence of data tampering, and lack of trust be-tween data sharing enterprises during the multi-value chain collaboration based on third-party platform, a blockchain-based data sharing method for multi-value chain collaboration was proposed. The framework of blockchain-based multi-value chain collaborative data sharing was proposed, which consisted of data source layer, data Integration layer, blockchain Service layer, multi-value chain collaborative data sharing layer and multi-value chain collaborative service layer. The data resource metadata model and establishment method for multi-value chain collaborative data integration and sharing were proposed. Then, the mechanism of multi-value chain collaborative data up-linking and the process of data integration, storage to blockchain, sharing were explained. The effectiveness of the proposed method was verified through a real case study of data sharing for multi-value chain collaborative repairment Services in the automotive industry. By utilizing the features of transparency, traceability, immutability of blockchain and the encryption algorithm, the security and trustworthiness of the data resource sharing process were guaranteed, which could better promote the development of multi-value chain collaborative Services. © 2024 CIMS.
