ELECTRONIC WAREHOUSE RECEIPT SOURCE TRACING METHOD AND APPARATUS, COMPUTER DEVICE, AND STORAGE MEDIUM

摘要

The embodiments of the present application belong to the technical field of blockchains, are applied to the field of intelligent logistics, and relate to an electronic warehouse receipt source tracing method. The method comprises: according to transfer information of an electronic warehouse receipt, configuring different nodes in a blockchain system for different participants of goods, wherein goods identity information of the same goods is the same, goods identity information of different goods is different, and each node corresponds to the different participants of the goods; when electronic warehouse receipt information written by the participants via the nodes is received, encrypting, by means of a data key, the electronic warehouse receipt information written by each node; and when a source tracing request sent by any node is received, according to goods identity information carried in the source tracing request, determining the electronic warehouse receipt information, which is written by each node and corresponds to the goods identity information, and transmitting the electronic warehouse receipt information to the node, so as to complete information source tracing. Further provided are an electronic warehouse receipt source tracing apparatus, a computer device and a storage medium. The present application realizes the whole-process traceability of the electronic warehouse receipt, and improves the credibility of the warehouse receipt.
