Research on Cold Chain Logistics Information Platform Based on Block-chain Technology

Blockchain has become a national strategy. In this context, blockchain technology will be widely used in all walks of life in the future. The blockchain is essentially a kind of database, which has the characteristics of decentralization and data immutability, which can greatly improve the accuracy and security of data records. Therefore, applying this function to cold chain logistics can not only improve the cold chain The ability of temperature monitoring and logistics information traceability in logistics can bring a qualitative leap to the improvement of cold chain logistics informatization. This paper starts from the cold chain transportation scenario, combines blockchain, edge computing, and the Internet of Things, and starts from an engineering perspective to build an end-to-end cold chain logistics edge technology demonstration and verification system based on blockchain. Connect the temperature sensor through the IoT in-vehicle 4G industrial edge computing router. The backend data center uploads the hash value of the collected information file to the blockchain cloud processing, while verifying how the blockchain prevents data tampering.
