The embodiment of the disclosure relates to block chain-based distributed storage, and discloses a block chain-based distributed storage method. The method includes: 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 includes: 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, according to the embodiment of the disclosure, tampering proofing and the distributed storage of the file can be realized through combining a block chain and a distributed file system, thus the problem of the limited capacity of block chain nodes is solved, and the authenticity and the availability of the stored file are effectively guaranteed. 本公开的实施例涉及基于区块链的分布式存储。公开了种基于区块链的分布式存储方法。该方法包括获得要被存储的文件并且生成针对该文件的哈希值和哈希值的索引。该方法还包括将哈希值记录在区块链网络中并且将文件存储在分布式网络中，其中文件在分布式网络中基于哈希值被定位。因此，本公开的实施例通过将区块链和分布式文件系统相结合，能够实现文件的防篡改和分布式存储，
