基于联盟区块链及IPFS技术的数字档案分布式应用平台设计研究

Research on the construction of digital archives distributed application platform based on consortium blockchain and IPFS technology

在互联网时代背景下,数字档案建设正快速推进。但是,目前已有的数字档案应用系统在存储容量、分布式容灾备份、有序共享及可溯源、确保安全性等方面存在明显瓶颈。如何利用包括区块链技术和分布式技术在内的新一代信息技术研发新的数字档案分布式应用平台已成为研究热点。首先,对数字档案分布式应用平台进行了需求分析。其次,进行了数字档案分布式应用平台所需的区块链分布式存储模型及数字档案移交模型等关键模型设计、区块链账本设计和分布式存储集群设计。接着,设计了基于Fabric联盟链和IPFS技术的数字档案分布式应用平台,并给出了档案移交及其密钥生成的智能合约算法实现等环节。最后进行了系统测试。相关工作为数字档案的海量分布式存储及容灾备份、有序共享及可溯源提供了新的、更可靠的技术保障。

In the context of the Internet era,the construction of digital archives is advancing rapidly.However,the existing digital archive application systems have obvious bottlenecks in terms of storage capacity,distributed disaster recovery backup,orderly sharing and traceability,and ensuring security.How to use the new generation of information technology including blockchain technology and distributed technology to build a new distributed application platform for digital archives has become a research hotspot.Firstly,the demand analysis of the digital archives distributed application platform is carried out.Secondly,the key model design,blockchain ledger design and distributed storage cluster design,such as the blockchain distributed storage model and digital file transfer model required by the digital archives distributed application platform,are carried out.Then,a distributed application platform for digital archives based on Fabric consortium chain and IPFS technology is constructed,and the implementation of the smart contract algorithm for archive handover and key generation is described.Finally,a system test was carried out.The related work provides a new and more reliable technical guarantee for the massive distributed storage and disaster recovery backup,orderly sharing and traceability of digital files.
