Used Car Traceability System Based on Blockchain

With the continuous expansion of China’s used car market., there are more and more accidents caused by the untrue information of used car quantity. And the current used car traceability system has some problems, such as incomplete information coverage and low reliability. The emergence of blockchain can improve this situation. It can be regarded as a decentralized, disintermediated and trusted public distributed ledger. Based on blockchain technology, this paper analyzes the needs of used cars from entering the market to selling, and establishes a transparent and reliable used car traceability system to realize the traceability of used cars from entering the market to selling, so as to further ensure the quality and safety of used cars.
