Blockchain technology comes from Satoshi Nakamoto and Bitcoin. It contains distributed data storage, point-to-point transmission, consensus mechanisms, encryption algorithms and other technologies. It is also one of the most secure information storage solutions now. The perfect combination of IPFS and blockchain enables users to use IPFS to store a large number of files, to ensure both the security of the file and the uniqueness of the file. This paper is based on IPFS, to improve and explore the traditional university file storage system.
