File storage method and apparatus for blockchain network

A file storage apparatus for a blockchain network, comprising:

• one or more processors, and a memory coupled to the one or more processor and stored with a plurality of modules executable by the one or more processors, wherein the plurality of modules comprises:
• a partitioning module, configured to partition an input file into a plurality of file blocks;
• a relationship establishing module, configured to establish a corresponding relationship between index values of a plurality of storage nodes and identifications of the plurality of storage nodes;
• a Hash operation module, configured to perform a Hash operation on one of the plurality of file blocks and obtain a first identification according to a result of the Hash operation and the corresponding relationship;
• a storing module, configured to store the one of the plurality of file blocks to a first storage node corresponding to the first identification.

A file storage apparatus for a blockchain network, comprising:

• one or more processors;
• and one or more memories coupled to the one or more processors, the one or more memories storing program instructions for causing, when executed, the one or more processors to perform:
• S1 partitioning an input file into a plurality of file blocks;
• S2, establishing a corresponding relationship between index values of a plurality of storage nodes and identifications of the plurality of storage nodes;
• S3, performing a Hash operation on one of the plurality of file blocks, and obtaining a first identification according to a result of the Hash operation and the corresponding relationship;
• S4, storing the one of the plurality of file blocks onto a first storage node corresponding to the first identification.
