Decentralized network file storage method and device, equipment and storage medium

The invention relates to the field of data management, and discloses a decentralized network file storage method, device and equipment and a storage medium, and the method comprises the steps: carrying out the fragmentation processing of original data, and generating a first number of fragmented data blocks; adding erasure codes to the fragmented data blocks to generate erasure code blocks; and copying each fragment data block and each erasure code block to generate a copy data block, and storing the copy data block in each storage node. By means of the mode, after original data are fragmented, the first number of fragmented data blocks are generated, the erasure codes are added to the fragmented data blocks, the second number of erasure code blocks are generated, the fragmented data blocks and the erasure code blocks are stored to the l eaf node, and after the DAG tree is generated, the third number of copy data blocks are generated; and the copy data blocks are stored in the storage nodes, so that the file
