基于私有链的存证云盘系统方案设计

Scheme Design of Cloud Storage System Based on Private Chain

提出一种区块链的私有链架构,利用中心化的网络优势,解决云盘海量文件并发存证的高性能问题;利用中心化的审计中心提供记账账本以及离线监督的方式实现全网共识机制;并设计了一种堆叠式安全文件系统,能够与云盘的分布式文件系统有机融合,对存储在云盘上的文件实现透明的存证处理。为私有网络环境特别是内外网隔离的环境提供了一种有效的区块链应用模式。

This paper proposes a private chain architecture for blockchain, which uses the advantages of a centralized network to solve the high-performance problem of concurrency and storage of massive files in cloud disks; It uses a Centralized Center Auditor（CPA） to provide the account book and off-line implementation to achieve the entire network consensus mechanism;We designed a stackable security file system which can be integrated with the cloud disk distributed file system, it can store the certificate transparently while user stores files. The private blockchain architecture proposed in this paper provides an effective blockchain application model for the private network environment, especially the isolation of internal and external networks.
