Abstract

The invention provides a block chain-based product traceability method. The method comprises the steps: obtaining a first ticket circulation record identification when a first ticket holder calls a ticket circulation interface, and judging whether the calling of the ticket circulation interface by the first ticket holder is a legal operation or not through an intelligent contract; if yes, judgingwhether ticket circulation is normal or not through a smart contract according to the first ticket circulation record identifier; if the ticket circulation is normal, broadcasting a first ticket circulation record to the block network, storing a second ticket holder to which the ticket flows by using the smart contract, and storing the first ticket circulation record into the block chain; receiving a ticket query command; if it is judged that the ticket corresponding to the ticket query command exists by using the smart contract, feeding back all ticket data of the ticket to an initiator of the ticket query command. The invention further provides a block chain-based product traceability device, electronic equipment and a computer readable storage medium, which all have the above beneficialeffects and are not repeated herein.

Description

technical field [0001] This application relates to the technical field of product traceability, and in particular to a blockchain-based product traceability method, a blockchain-based product traceability device, electronic equipment, and a computer-readable storage medium. Background technique [0002] The authenticity of products has always been a pain point that needs to be solved urgently in various industries. The high-frequency and large-scale commodity counterfeiting has made the public's demand for commodity traceability increasing. How to effectively trace the production and transportation information of commodities has become the focus of industry research. The existing traceability method is to store the commodity information in the server, and the user terminal can retrieve the commodity information to obtain the product information, but the stored information is easy to be tampered with. [0003] Therefore, how to provide a solution to the above technical probl...
