Block chain big data security processing system

The invention, which relates to the technical field of big data security protection, discloses a block chain big data security processing system comprising a data acquisition module, a big data storage module, a security processing module and an exception feedback module. And the data acquisition module is used for acquiring data of each block in the block chain, setting acquisition duration and acquisition interval, and realizing real-time acquisition and uploading of system network data. According to the invention, security processing is carried out on a large amount of data in the block chain through the security processing module, the problems of attack defense, data protection, crash recovery and the like in current data interaction, circulation, sharing and security defense are solved, DDOS attacks are relieved, user information, important data and the like are all comprehensively and effectively protected, and the security of the block chain is improved. The safety state of the block chain data is moni
