Abstract

The invention relates to the technical field of automobile trading, in particular to a method, a device, a device and a storage medium for sharing automobile data based on a block chain. The methods include: the host plant node obtains a unique identification corresponding to the automobile information and the automobile information, generating an automobile detail block, and uploading the block in the block chain system to form a new block chain; the host plant node broadcasts the uploaded automobile detail block to other nodes; after receiving the broadcasting, the other nodes record the unique identification, the automobile information and the hash value; The dealer node obtains maintenance information, generates maintenance blocks, and uploads and broadcasts them. The invention introduces a block chain system and constructs an information sharing system for automobiles from production to sale by virtue of the decentralization characteristic of the block chain, realizes the purposeof multi-participation of each link and joint maintenance of automobile data on the block chain, and provides reliable automobile data for the estimation of used automobiles.

Description

technical field [0001] The present invention relates to the technical field of automobile transactions, in particular to a block chain-based automobile data sharing method, device, equipment and storage medium. Background technique [0002] In the second-hand car trading market, the valuation of second-hand cars is very important. The general process of second-hand car valuation is usually the second-hand car dealer picks up the car, inspects the car, and evaluates the pre-sale price. When evaluating the pre-sale price of a used car, the pre-sale price is comprehensively evaluated according to the following indicators: [0003] 1. Credible indicators: brand, model, license plate time, appearance and interior wear; [0004] 2. Untrustworthy indicators: mileage, overhaul, major accident, replacement of auto parts, daily use. [0005] Among them, for untrustworthy indicators, second-hand car dealers cannot obtain accurate data, but other links in the automobile industry chai...
