Fig. 3 is a schematic diagram of a system in which a block chain-based product information processing method according to an embodiment of the present invention is applied to an electric home appliance. The household electrical appliance product is circulated in production, transportation and sale links, and the circulation process and product information are recorded.
The household appliance production line 31 writes the digital certificate into the RFID tag of the product according to a customized rule, and binds the digital certificate with the corresponding product. The trusted node 310 generates a trusted digital certificate (i.e., digital asset) and chains up the RFID trusted data and the digital asset simultaneously. The circulation of subsequent products is accompanied by the transfer of the trusted voucher.
The home appliance production line 31 may also be configured with a plurality of streaming nodes 311, such as one or more assembly nodes and one or more detection nodes. The assembly node is used for recording assembly information, and the detection node is used for recording detection information.
A warehousing node 331 may be provided at the household appliance repository 33 for recording warehousing information.
A plurality of circulation nodes 321, such as a sales node, a transportation node, and a purchase node, may be provided on the sales distribution line 32 of the home appliance.
The final sold product 341 can be traced by the user terminal 321 through the RFID scanning method to the data of all the production and circulation links of the product, thereby completing the tracing of the product. The terminal 321 obtains the relevant information through the network access block chain. In order to prevent counterfeiting, each product is produced, a corresponding credible certificate is generated, the circulation of the product is accompanied with the circulation of the credible certificate, and only the credible certificate corresponding to the product and the product which are owned simultaneously is considered as a genuine product. Thus, even if the label can be counterfeited, the digital certificate cannot be counterfeited. Thereby fundamentally avoiding the problem of counterfeiting.
A series of product data recorded on the blockchain form digital assets corresponding to the products, and the corresponding digital assets can be determined through digital certificates owned by users or users. The user further obtains the digital assets on the blockchain in addition to the assets having the physical attribute of the product. For some special products (such as famous gifts, collections, artworks) and the like, the value of the digital assets recorded on the blockchain cannot be influenced even if the physical attributes of the products are lost.
The digital assets can be used as NFT (Non-variant Token), the circulation process of the digital assets embodies uniqueness, and the digital assets have values. For example, for goods with higher value (such as collections, artworks) and the like, the information is accumulated in each circulation process, so that the digital certificate forms independent value on the block chain. The user may also indicate, via the digital voucher, his rights to the corresponding digital asset or rights that he has ever possessed.
The method of the embodiment is applied to high-value products (such as famous and precious gifts, collections and artworks), and digital assets can be accumulated and circulated correspondingly while the products are circulated; in some alternative embodiments, the digital assets recorded on the blockchain are still of value for circulation even if the physical attributes of the product are lost.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
