This study aims to construct a traceability system tailored for the mango industry in Panzhihua City, Sichuan Province, which integrates the decentralized and immutable nature of blockchain with the real-time data acquisition capabilities of the Internet of Things (IoT) to enhance the transparency and traceability of the mango production chain. The article elaborates on the system design rationale, architecture construction, database design, deployment and implementation of smart contracts, IoT data processing mechanisms, as well as the application of query optimization and fault-tolerant algorithms. Through actual deployment and testing, the system's effectiveness and reliability have been verified, significantly improving the accuracy and efficiency of mango traceability and providing solid technical support for quality and safety control in the mango industry of Panzhihua City.
