Trusted Collection Mechanism of Short Shelf-Life Food Based on Multi-Chain Blockchain

Due to their high freshness, good taste, and convenience, short shelf-life foods are playing an increasingly important role in people's daily diet. The short shelf-life food supply chain has the characteristics of a short lifecycle, fast information exchange at each link, and a large number of participants, leading to issues such as low credibility of multi-source data and insufficient standardization of regulatory processes in the production, processing, and sales of short shelf-life foods. Currently, relying solely on rapid inspection equipment and individual enterprise information systems cannot meet the trustworthy security requirements of the entire chain. Therefore, this paper proposes a trusted management framework and collection mechanism for short shelf-life foods based on blockchain and trusted security protocols. Firstly, a trustworthy information management framework for short shelf-life food supply chains is constructed based on a multi-chain blockchain. Then, a trustworthy transmission protocol for short shelf-life foods is designed based on cryptography and transmission protocols, and the process is implemented using RFID as the carrier. Finally, based on the Chainmaker open-source blockchain framework, a trustworthy management system for short shelf-life foods is designed, implemented, and tested. This research can provide a trustworthy execution environment for the information management of short shelf-life food supply chains, and provide information security for food quality and safety.
