Research on Product Life Cycle Data Traceability Based on Multi-Blockchain

Realizing process data traceability of industrial products is an important way to solve the problem of product quality analysis and achieve optimal design. At present, research on product data traceability mainly relies on centralized service provider storage, and product data rarely covers the whole life cycle, resulting in the opacity and incomplete of the product traceability process data. In this paper, blockchain technology is introduced into the traceability management of product data, and a product life cycle data traceability method based on multi-blockchain is proposed. The data sharing and communication mechanisms among blockchains are analyzed. Moreover, the block structure of product traceability data, the upload process of block data and the tracing process of multi-chain product data are elaborated in detail. Finally, based on the open source ethereum architecture, the system application platform is developed to verify the feasibility and rationality of the proposed method.
