Abstract

The invention relates to a commodity tracing method and device based on a block chain, computer equipment and a storage medium. The method comprises the following steps: registering equipment information of each piece of commodity traceability equipment in a commodity operation process in an alliance chain server or a public chain server, wherein the equipment information comprises an equipment identifier, an equipment category and an equipment position; commodity traceability information is obtained through the commodity traceability device; when the commodity traceability information contains privacy information, uploading the commodity traceability information to the alliance chain server; when the commodity traceability information does not contain privacy information, uploading the commodity traceability information to the public chain server, wherein the alliance chain server is used for being inquired by authorized equipment, and the public chain server is used for being inquired by all equipment. According to the method, the privacy information of a commodity can be prevented from being leaked when the commodity information is traced.

Description

technical field [0001] This application relates to the field of computer technology, in particular to a method and device for commodity traceability based on blockchain. Background technique [0002] Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. The underlying technology of the currency is a series of data blocks associated with cryptographic methods. Each data block contains a batch of bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate The next block, with the development of blockchain technology, practice has proved that blockchain technology can better reduce the trust risk in the process of multi-party collaboration. The existing use of blockchain technology for product traceabi...
