The Traceability of Millet Based on Blockchain Smart Contracts in Agricultural Supply Chain

As global agricultural production and supply chains become increasingly complex, the demand for food safety and transparency is also growing. Agricultural traceability, as a process of tracing products from production to consumption, can help relevant departments locate the problematic links when agricultural products have issues. However, traditional agricultural traceability carries the risks of tampering with traceability data, as well as problems of information silos and opacity. Blockchain technology provides a reliable solution for agricultural traceability, ensuring data security and transparency, while also improving the efficiency and accuracy of traceability. This paper proposes a method based on blockchain smart contracts for millet information traceability. The method includes the architecture and algorithms of millet traceability based on blockchain smart contracts, as well as the interaction and process between the main participants and the smart contract. In addition, we conducted a performance evaluation of the designed smart contract.
