Advancing cold-chain medicine logistics and emergency supplies management necessitates a robust blockchain-based traceability system. This specialized information system is essential for enhancing quality control and operational efficiency. Despite challenges like insufficient supplies, ineffective distribution, and delays, blockchain's transparency and traceability offer significant potential to revolutionize national emergency management. This paper presents a blockchain-based traceability system tailored for cold-chain medicine logistics. This system achieves traceability and automatic medicine quality assessment by integrating blockchain principles and leveraging hazard analysis theory combined with IoT technology. This system also enhances data reliability with a multi-sensor data fusion algorithm, improving temperature accuracy beyond conventional methods. Additionally, the feasibility and necessity of integrating blockchain into cold-chain pharmaceutical traceability processes is thoroughly examined. The proposed system fulfills traceability needs for emergency cold-chain medicine while addressing industry challenges.
