Title: BLOCK CHAIN-BASED DISTRIBUTED STORAGE
Abstract:
Disclosed is a block chain-based distributed storage method. The method comprises: obtaining a file which needs to be stored; and generating a hash value and an index of the hash value for the file. The method also comprises: recording the hash value in a block chain network; and storing the file in a distributed network, wherein the file is located on the basis of the hash value in the distributed network. Therefore, tampering proofing and the distributed storage of the file can be realized through combining a block chain and a distributed file system, thereby solving the problem of the limited capacity of block chain nodes, and effectively ensuring the authenticity and the availability of the stored file.
