A novel food traceability scheme based on multi-tier cooperation consortium blockchain

Recently, Blockchain technology has been widely used in food traceability service. However, several problems are still not properly solved in the current schemes, such as the inconvenience of management, the lacking private information protection of participants and the poor performance in external traceability service. In this paper, we propose a novel food traceability Scheme based on multi-tier cooperation consortium blockchain. In our approach, business and data are managed by hierarchical architecture, private information of traceability participants is effectively protected and performance of external service is improved at the same time. Experimental results based on Hyperledger Fabric framework validate the proposed solution.
