Fig. 3 is a schematic diagram of a system in which a method for processing product information based on blockchain is applied to home appliances according to an embodiment of the present invention. Household appliances are circulated in each link of production, transportation and sales, and the circulation process and product information are recorded.

The home appliance production line 31 writes the digital certificate into the RFID tag of the product according to the self-defined rules, and binds it with the corresponding product. The trusted node 310 generates trusted digital certificates (that is, digital assets), and uploads the RFID trusted data and digital assets to the chain at the same time. The circulation of subsequent products is accompanied by the transfer of trusted credentials.

The home appliance production line 31 can also be configured with multiple circulation nodes 311 , such as one or more assembly nodes and one or more testing nodes. Assembly nodes are used to record assembly information, and detection nodes are used to record detection information.

A warehouse-in node 331 may be set at the home appliance storage warehouse 33 for recording storage information.

Multiple transfer nodes 321, such as sales nodes, transport nodes, and purchase nodes, may be set on the sales distribution line 32 of the home appliance.

The product 341 after the final sale can be traced by the user terminal 321 through RFID scanning to trace all the data generated in the circulation link of the product, thereby completing the traceability of the product. The terminal 321 accesses the blockchain through the network to obtain relevant information. In order to prevent counterfeiting, each time a product is produced, a corresponding credible certificate will be generated, and the circulation of the product will be accompanied by the circulation of the credible certificate. Only those who have both the product and the credible certificate corresponding to the product will be considered authentic. In this way, even if the label can be faked, the digital certificate cannot be faked. Thereby fundamentally put an end to the problem of fraud.

A series of product data recorded on the blockchain form the digital assets corresponding to the products, and the corresponding digital assets can be determined through the digital certificates owned by the user or user. In addition to assets with the physical attributes of products, users further obtain digital assets on the blockchain. For some special products (such as precious gifts, collectibles, works of art), etc., even if the physical attributes of the product are lost, it will not affect the value of the digital assets recorded on the blockchain.

The above-mentioned digital assets can be used as NFT (Non-Fungible Token, non-homogeneous assets), and its circulation process reflects its uniqueness and its own value. For example, for commodities with high value (such as collectibles, works of art), etc., the accumulation of information in each circulation process makes digital certificates form independent value on the blockchain. Through digital certificates, users can also indicate their rights to the corresponding digital assets or the rights they once had.

The method of this embodiment, when applied to high-value products (such as expensive gifts, collectibles, works of art), while the products are in circulation, digital assets can be accumulated and circulated accordingly; in some optional embodiments, even if the physical properties of the product Loss, the digital assets recorded on the blockchain still have the value of circulation.

So far, those skilled in the art should appreciate that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, without departing from the spirit and scope of the present invention, the disclosed embodiments of the present invention can still be used. Many other variations or modifications consistent with the principles of the invention are directly identified or derived from the content. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
