Embodiment Construction

[0016] Various exemplary embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. The flowchart and block diagrams in the figures illustrate the architecture, functionality, and operation of possible implementations of methods and systems according to various embodiments of the present disclosure. It should be noted that each block in a flowchart or a block diagram may represent a module, a program segment, or a part of a code, and the module, a program segment, or a part of a code may include one or more An executable instruction for a specified logical function. It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or they may sometimes be executed in the reverse order, depending upon the functionality involved. It should also b...

Abstract

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.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the technical field of file storage, and more specifically relate to a blockchain-based distributed storage method and device. Background technique [0002] Blockchain is a decentralized storage and computing technology, which generates persistent and unmodifiable records by superimposing encrypted data blocks in chronological order, and will be stored in each node of the blockchain network, It enables collective maintenance of a reliable database in a decentralized manner. Each data block contains system data within a certain period of time, and generates data fingerprints to verify the validity of its information and link to the next database block. Therefore, the blockchain has technical advantages in terms of data tamper resistance, transparency and decentralization. [0003] Typically, Internet intermediaries use third-party digital signature companies to guarantee the authenticity of doc...
