Tax payment credit investigation system based on block chain and processing method

Abstract

The invention belongs to the technical field of tax system credit investigation management, and discloses a tax payment credit investigation system based on a block chain and a processing method, andthe method comprises the steps: accumulating data of each mechanism to a unified block chain platform, and integrating all information; using a specific consensus algorithm to input credit data into the block chain, and analyzing and calculating individual credit scores to form a huge information set; meanwhile, enabling the open port to continuously accept resources to form an information network, so that all participants are equivalent and mutually beneficial; constructing a tax platform introducing an interstellar file system using the interstellar file system for uploading duplicate text information, and directly storing a returned hash value and a small tax payment data file on a block chain which is used for a tax system and a credit alliance and caching the value and file in a standby traditional database at the same time. According to a data sharing method based on the block chain, member nodes in the regional autonomous alliance are mutually constrained and supervised while sharing data, and 'information island 'phenomenon is solved.

Description

technical field [0001] The invention belongs to the technical field of taxation system credit investigation management, and in particular relates to a blockchain-based taxation credit investigation system and processing method. Background technique [0002] At present, the commonly used prior art in the industry is as follows: at present, the State Taxation Bureau divides the classification of tax credit ratings into five grades of A grade, B grade, C grade, D grade and M grade.
