A Blockchain Consensus Optimization-Based Algorithm for Food Traceability

At present, blockchain technology is more and widely used in the field of food traceability, good results have been achieved. However, many current technologies algorithms are not developed for specific situation resulting resource waste low computational efficiency. In view these problems, this paper analyzes summarizes classic distributed consensus mechanism technology, focusing on PBFT (practical Byzantine fault tolerance) existing problems related to improvement scheme. order solve problem efficiency a algorithm traceability scenario, proposes suitable scenario based clustering credit. addition, differences between improved classical time communication times analyzed through experiments simulations. The significantly improved, which can greatly reduce application difficulty traceability.
