Problems solved by technology

[0004] Existing cloud storage relies on third-party large-scale storage providers to transmit and store data, such as 360 Cloud Disk, Baidu Netdisk, etc. These large-scale storage providers have all data backups and all user information, and are limited by the centralized architecture. Very vulnerable to various security threats

Abstract

The invention discloses a storage system based on a block chain, which comprises an application layer, a block chain network and a distributed storage network, wherein the application layer is used for an uploader to generate an uploading request, a storage user to generate a storage request and a downloader to generate a download request and for segmenting the file to be stored into a plurality of file fragments according to the uploading request; the block chain network is used for storing the uploading request, the downloading request and the meta information of the file and for carrying out authority verification on the downloader initiating the download request; the distributed storage network is used for storing the file fragments, performing the authority verification on the storageuser when the file is uploaded, and carrying out authority verification on the downloader when the file is downloaded. According to the storage system, the block chain technology is adopted to storethe meta information of the file in the block chain network, so that the file cannot be tampered, the safety is greatly improved, the stability which is provided by the electric power network is combined; and stable and safe cloud storage is realized.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a blockchain-based storage system. Background technique [0002] Cloud storage is a new concept extended and developed on the concept of cloud computing. It is an emerging network storage technology. A large number of different types of storage devices work together through application software to jointly provide data storage and business access systems. [0003] When the core of cloud computing system computing and processing is the storage and management of large amounts of data, a large number of storage devices need to be configured in the cloud computing system, then the cloud computing system will be transformed into a cloud storage system, so cloud storage is a data storage and management as the core cloud computing system. Simply put, cloud storage is an emerging solution to put storage resources on the cloud for people to access. Users can connect to the cloud th...
