Problems solved by technology

[0003] Existing healthcare product trading platforms lack an effective credit investigation system and comprehensive risk prevention measures. It is difficult to eradicate the counterfeit and shoddy products in the supply chain under the background of economic globalization and the safety risks caused by them. Customers are not only worried about the efficacy and In addition to security, they also care about the authenticity of the transaction information itself, so it takes time and energy to verify the authenticity of the transaction, which increases additional transaction costs;

[0004] Since there are a large number of health care products on the health care product trading platform, there are the following defects: 1. The needs of buyers cannot be accurately identified; 2. It is difficult for buyers to identify the true quality of health care products, and it is easy to buy products with poor quality at high prices; 3. There is no measurement scale and reference standard for the transaction price of health care products, resulting in no guarantee for the transaction. For this reason, we propose a transaction management system based on blockchain
