| Abstract: In multimodal transportation of cold chain logistics, the uneven service capabilities among participants and the lack of mutual trust lead to low collaborative efficiency. Meanwhile, traditional temperature control and monitoring methods are plagued by issues such as data vulnerability to tampering and insufficient transparency, which seriously affect supply chain efficiency and food safety. To address these problems, this paper proposes an end-to-end traceability solution integrating highly trusted SoC(System on Chip) chips and blockchain. Specifically, embedded SoCs are adopted to achieve hardware-level tampe-r proof storage at the temperature data collection end; blockchain is utilized to ensure data integrity, traceability, and secure cross-entity sharing; and cloud computing is integrated to support efficient querying and rea-l time verification, covering the entire process. Application results indicate that this scheme significantly enhances the credibility and transparency of cold chain data, providing effective support for safeguarding food safety. |
