File access method and device based on block chain storage technology

The embodiment of the invention provides a file access method and device based on a block chain storage technology, which can be used in the technical field of artificial intelligence, an optimal network node is selected based on user side access and network overall resource conditions updated in real time by a system, and the file access efficiency is improved by adopting block chain multi-level cache of local cache and distributed cache. Quickly acquiring file fragments to generate a target file; file fragments are stored in a distributed manner, so that single-point faults are avoided, and the availability of the system is improved; the optimal network node is allocated to the user access request based on the real-time attitude resource condition for access processing, and real-time and efficient data access is realized in the use process of the user. 本发明实施例提供了一种基于区块链存储技术的文件访问方法和装置，可用于人工智能技术领域，基于用户侧访问和系统实时更新的网络整体资源情况选取最优网络节点，通过采用本地缓存和分布式缓存的区块链多级缓存，快速获取文件碎片生成目标文件；通过分散式存储文件碎片，避免出现单点故障，提高系统可用性；基于实时姿态资源情况为用户访问
