LDBC (Logistics Data Block Chain) is a fusion of the Internet of Things theory and blockchain technology, committed to creating a big data blockchain that connects everything. The traditional IoT operating platform adopts centralized technology, and both data collection and operation are based on the premise that any party participating in the IoT is responsible. Due to the slow development of trust mechanisms, it seriously hinders the development of the IoT market. In response to the problems that arise during the process of the Internet of Things, IoT focuses on the data acquisition, data concurrency, and data coexistence issues faced by the application of blockchain technology in the IoT industry. Combining blockchain IoT big data, a new generation IoT system architecture is constructed, mainly used in the logistics industry....
