Abstract: 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.
