Description

Decentralized transaction object determination system and method

Technical Field

The invention relates to the technical field of block chains, in particular to a decentralized transaction object determination system and method.

Background

In the existing trade between the producer and the consumer, the trade is often completed through intermediaries such as an intermediary merchant and an e-commerce platform.

The consumer purchases the product through the intermediary, so that not only is the economic cost increased, but also the originality and the correctness of the product information can not be ensured, and the risk and the burden of using the product by the consumer are further increased.

When a consumer searches and purchases products on an e-commerce platform, search results may be inclined according to the platform fee paid by the producer, and it is highly probable that the products arranged in front are not really required by the consumer but are producers with more platform fees. Even some merchants pass platform fees to consumers as a production cost, further increasing the economic cost of the consumer.

From a technical point of view, the large and medium dielectric merchant platform at present can easily establish direct contact between a producer and a consumer. However, if the two are directly connected, the producer does not need to pay the platform fee, and the benefit of the intermediary is influenced. Therefore, a method for directly determining a transaction object by a producer and a consumer is lacking at present.
