区块链技术源于中本聪和比特币，包含分布式数据存储、点对点传输、共识机制、加密算法等技术，是目前最安全的信息存储方案之一。IPFS 和区块链的完美结合，使得用户可以使用IPFS 来存储大量文件，既能保证文件的安全性，又可以确保文件的唯一性。本文基于IPFS 的区块链存储技术，对传统的高校文件存储系统进行改良和探究。

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.
