Automobile valuation system and method based on block chain

Abstract

The invention discloses an automobile valuation system and method based on a block chain, and the method comprises the steps: firstly proposing a loyalty degree, a reward and punishment mechanism anda reputation leasing concept which are combined with a service address, a reward and punishment reputation verification excitation model and a formula analysis argumentation according to a verification economic idea and a reputation verification contract interaction relation; secondly, designing and realizing a task scheduling algorithm and a revenue distribution algorithm in a pass scene; and finally, designing and realizing application transformation of the Bancor protocol in the intelligent contract. The problems are solved by using a plurality of technologies such as a block chain, an IPFSand a database, more technical advantages are brought, and the truth and credibility of the second-hand vehicle data are ensured by using the traceability and tampering difficulty of the second-handvehicle data; the system is linked by compiling the intelligent contract, so that the system can continuously run under the condition of no operation, and the operation and maintenance cost is reduced; by redesigning the data model, the privacy of the data can be ensured, and the shareability of the data can also be ensured.

Description

technical field [0001] The present invention relates to the field of block chain technology, and more specifically relates to a block chain-based automobile valuation system and method.
