As the Guangdong-Hong Kong-Macao Greater Bay Area's economy continues to thrive, market demands for agricultural product quality are steadily increasing, with safety attributes and traceability becoming core requirements. Ensuring product quality and safety while optimizing logistics efficiency has made establishing cold chain traceability systems a critical practice. Leveraging IoT technology for full-process temperature monitoring and blockchain technology to ensure data authenticity and verifiability, along with building a unified information exchange platform to facilitate cross-regional collaboration, ultimately establishes a comprehensive traceability mechanism covering all stages from production to sales. The implementation of this system not only significantly reduces product losses during logistics and strengthens quality assurance but also enhances consumer trust in market products, providing robust support for regional agricultural modernization and efficient supply chain operations.
