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...

Problems solved by technology

[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 transparency is relatively poor, so there are doubts about the reliability and authenticity of the information; at the same time, the maintenance of such a system is relatively scattered, causing manufacturers to maintain it separately for a long time. Said that the maintenance cost of the society is relatively high

Safe, reliable and comprehensive information exchange among commodity circulation participants is even more impossible
