Abstract

The invention discloses an export tax refund and financing method and device based on a block chain, and a medium, the export tax refund and financing method based on the block chain completely publishes information on the whole industrial block chain on the block chain through the block chain, through repeated confirmation of multiple mechanisms, the real transparency of the information is improved. And machine learning risk modeling is carried out by using block chain data, a risk control model of export tax refund loan is constructed, a supervision department data island is broken through, the authenticity and non-tampering property of the data are ensured through a block chain cryptography principle and a chain structure, and the problems of low efficiency and export tax fraud caused by information asymmetry are reduced. According to the invention, the information of all participants is recorded on the block chain, the supervision data is shared, the risk can be systematically measured, the trust degree among the participants can be deepened, and false cheating behaviors such as false orders and counterfeit certificates which may occur in export tax refund financing business are completely eradicated.

Description

technical field [0001] The present invention relates to the technical field of block chain, in particular, to a block chain-based export tax rebate financing method, equipment and medium.
