Abstract

The application provides a second-hand car transaction method and server, and the method comprises the following steps: receiving second-hand car sales information and a sales intelligent contract submitted by a seller client, registering the second-hand car sales information and sales intelligent contract in a block chain and broadcasting in the whole network; receiving a second-hand car transaction request submitted by a buyer client; searching matched second-hand car sales information according to the second-hand car transaction request and sending the matched second-hand car sales information to the buyer client; executing a target sales intelligence contract according to target second-hand car information selected by the buyer client; generating a second-hand car sales contract according to an execution result of the target sales intelligent contract, and registering in the block chain after obtaining confirmation by the buyer client and the seller client. In the process, the server registers the sales information of a second-hand car seller and the information of second-hand car purchase of a second-hand buyer in the block chain, so as to ensure that the second-hand car transaction data are secure and cannot be tampered, and ensure the security of the transaction data and the transparency of the transaction.

Description

technical field [0001] The present application belongs to the technical field of vehicles, and in particular relates to a second-hand car transaction method and server.

In traditional offline second-hand car transactions, second-hand car service personnel (such as intermediary personnel) generally collect cars offline, and then use personal experience to evaluate the condition of the second-hand car and the selling price. When the buyer comes to buy a car, he will negotiate with the buyer to determine the price of the used car. [0003] Although there is a vehicle evaluation link in the online used car transaction, the transaction platform is an online centralized platform, and the accuracy and fairness of the data in the transaction platform cannot be guaranteed. Therefore, the evaluation of all aspects of used cars by...
