technical field

The invention relates to the technical field of blockchain, in particular to a blockchain-based authentication and transaction traceability method, system and storage medium.

Background technique

The source of commodities is one of the indicators to measure the quality of commodities, and it can also reflect the value of commodities to a certain extent. Commodities with specific origins, manufacturers and other sources represent its special value, such as jade raw materials from Hotan in Xinjiang, and products from major mines in Myanmar. The jade products processed with them have higher collection value; some luxury decorations (watches, leather bags, etc.), because the origin has better processing technology and better raw materials, etc. When the country sells, it must also prove its source, which is used to prove the identity of the product and ensure that it is not an imitation; some distinctive agricultural products, such as green products from a certain farm, also need to use its proprietary source to prove that it is different. For other common agricultural products, there are many situations that need to prove the origin of commodities. Commodity traceability is the demand of many merchants, and it is also the demand of consumers to understand commodity attributes and commodity quality. Solving the problem of commodity traceability is very important for promoting commodity circulation and commodity trading Significance.

In the early traditional source of goods, the source of the origin and the manufacturer were written in the form of proof, and endorsed by the company's own reputation or by the relevant industry associations and management departments. For example, when imported goods are exported in the country of origin, there are customs confirmation The certificate of origin, which proves the manufacturer and city of the source of the goods.

With the development of technology, information technology means and equipment are gradually applied to the work of commodity traceability. Enterprises or third-party companies will record the source, processing, transportation, distribution, retail and other commodity circulation processes by establishing commodity traceability transaction systems. In the process, each link usually confirms the information of receiving and sending the goods to the next link, as well as the transfer of the ownership of the goods during the transaction process, forming a complete chain of commodity circulation information records, so as to trace the source and destination of the goods, and to the goods. Identity uniqueness and legality are authenticated.

However, with the popularization of technology, for example, in the field of cultural relics protection, simple traceability technologies such as QR codes, barcodes, and ID cards have gradually become able to be cracked and copied at low cost over time. It is impossible to carry out effective anti-counterfeiting, identification and traceability in the field of anti-counterfeiting and identification of articles, as well as in the circulation of articles.

At the same time, with the development and application of blockchain technology, the previous centralized verification and recording methods can no longer meet the requirements of security and reliability.
