Research on the Used Car System Based on Blockchain and Cryptographic Technology

Abstract

Different countries have different issues with related to topic of used car in all of world, and used car issues involve very wide range of fields, such as environmental protection, market economy, sales services, information systems, regulations and policies, components, materials, and logistics so on. In this study the authors would like to propose a scheme of used car transaction information system from perspective of mathematical modelling. We introduce the concept of a third party appraiser as an arbitrator between buyers and sellers in this solution. In order to avoid collusion between third parties and sellers, the blockchain and cryptography technology be used to prevent collusion and ensure fair and just transactions.
