Abstract: Grains and oils are necessities for human life, and grains and oils supply chain security is directly related to people’s health. Due to the features of the grains and oils supply chain such as complex nature, long cycle time and multiple risk factors, how to effectively protect the safety of grains and oils during production, processing, storage, transportation and sale is a common concern for the whole world. Based on the blockchain technology, this paper constructs a credible traceability model for the whole supply chain of grains and oils which can solve the drawbacks of the current traceability system including serious structural centralization, low data security and the existence of information islands, and can ensure data security and reliability in the entire supply chain as well as provide accurate and credible traceability information. Further, a credible traceability prototype system for the whole supply chain of grains and oils is designed, and the effectiveness and feasibility of the design scheme are demonstrated based on specific application scenarios and cases.

Key words: blockchain, grains and oils, credible traceability, whole supply chain, smart contract, food safety
