Block chain-based commodity circulation information query system and method

Abstract

The invention discloses a block chain-based commodity circulation information query system and method. The system comprises a portable mobile terminal system and a block chain system, wherein the terminal system comprises an input module, a conversion module, a login module, a search module, an output module and a display module; the input module obtains a commodity code; the conversion module converts the obtained commodity code into a unique ID on a block chain; the login module obtains a public account registered in the block chain system of a public network by the terminal system, and logs in the block chain system; the search module is based on circulation information required for ID search; the output module outputs the information to users; the display module displays the information in the terminal system according to a time sequence; a classification unit of the display module classifies the information to realize display by types or levels; and a sharing unit of the display module performs information sharing among the users. A set of query system is established; and the query system is open, free of central storage and transparent in management, and supports a mobile phone end.

Description

technical field [0001] The invention relates to the field of commodity circulation information query, in particular to a blockchain-based commodity circulation information query system and method. Background technique [0002] Usually in daily life to query product information, the system flow is as follows figure 1 As shown, we can know the process of querying information about a product. This system has the following disadvantages: [0003] (1) Inquiry is mainly through the information number provided by the manufacturer; it is inconvenient to inquire if the source of the number is not unified; the method is not portable enough; [0004] (2) The database in the L2 link is closed in the hands of the manufacturer and is easily controlled by the manufacturer; [0005] (3) The L2 data center is not robust enough. When the data center is blocked or the server is paralyzed, it cannot be accessed; [0006] (4) The entire system is controlled by the manufacturer, and the authen...

[0005] (3) The L2 data center is not robust enough. When the data center is blocked or the server is paralyzed, it cannot be accessed;

[0006] (4) The entire system is controlled by the manufacturer, and the authenticity of the information is questionable, and may even be faked;

[0007] from figure 1 From the above, we can know that such an information system is relatively closed, there are still flaws, and the management transp
