METHODS, APPLICATION SERVER, BLOCK CHAIN NODE AND MEDIA FOR LOGISTICS TRACKING AND SOURCE TRACING

摘要

Embodiments of the present disclosure provide methods, an application server, a block chain node and storage medium for logistics tracking and source tracing of an object. The application server includes a memory and a processor, the memory being stored with machine executable instructions that, when executed by the processor, cause the application server to perform operations including: receiving a storage request from at least one node during a logistics process of the object; performing a hash operation on the information to obtain a hash value of the information; sending the hash value of the information and the information to a distributed database for storage; and sending the unique identification number of the object and the hash value of the information to a block chain platform for storage. With the embodiments of the present disclosure, it may be ensured that the object to be transported will not be replaced during the transportation process and that the information of the object will not be leaked or tampered with.
