Description

Commodity transaction method and system based on block chain

Technical Field

The invention relates to the field of block chains, in particular to a commodity transaction management method and system based on a block chain.

Background

In addition to the rapid advance of product sales, the widespread application of electronic commerce also brings the sweepness of counterfeit and inferior products, especially in the second-hand market, and even after the goods in the second-hand market are renewed in one-hand market, the phenomenon is particularly serious in the retail industry of electronic products. In order to solve the problem, many merchants provide services for verifying authenticity and inquiring the number of times of use, but due to frequent hacker events, bad merchants directly copy websites for verifying authenticity, directly buy database administrators or other personnel to modify the number of times of use of inquiry, and the services for relieving counterfeiting and faking become services which cause consumers to lose confidence. More bad merchants use the characteristic that the second merchant serves as a second hand by using four or five hands, and the first merchant serves as a first product by using defective products, returned products and second products; therefore, the problem that the product can be effectively traced back, the number of times of product hand turning is really recorded in the second-hand market, and the situation that the product is controlled and tampered by a bad merchant to be urgently needed to be solved is solved.
