Problems solved by technology

However, there will be the possibility of payment behind the IPFS public network. In addition, IPFS currently has some policy risks, so it is not recognized for the time being.
Fabric is a blockchain technology suitable for consortium chains, but Fabric only supports data storage of less than 99M by default, and Fabric's full-node redundant storage method consumes a lot of cost, so it is difficult to store massive data

Embodiment Construction

[0056] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0057] First of all, the following definitions or descriptions are given for some terms involved in the present invention.

[0058] DAPP: DAPP is the abbreviation of Decentralized Application, which means distributed application program, which is an application program built on the blockchain system. The most obvious difference between it and the traditional application APP: DAPP runs on the decentralized network, that is, the blockchain network. There is no centralized node in the network that can completely control DAPP; APP needs to request a certain server to obtain data, process data, etc.

[0059] Fabric: A blockchain framework, one of the project members of Hyperledger, which belongs to the distributed smart contract platform.

[0060] IPFS: The abbreviation of InterPlanetary File System, the Interplanetary F...

Abstract

The invention provides a file processing method. The method is applied to a first user side and comprises the steps that after it is confirmed that primary user registration and identity verificationare passed, generating a public key and a private key which are matched with each other, the first user side stores the private key locally, and a DAPP registers the public key uploaded by the first user side to a Fabric network through a preset Fabric node; when a file uploading signal is detected, obtaining a to-be-uploaded file, and obtaining a public key; encrypting the to-be-uploaded file byusing the public key, and uploading the obtained first encrypted file to the DAPP; the DAPP splits the first encrypted file into a plurality of file blocks, and stores the file blocks to an IPFS storage node in an IPFS network; and the DAPP stores the node address returned by the IPFS storage node for storing the file block to a preset storage position. The invention further provides a user side,a server and a readable storage medium. The invention aims to provide a decentralized data storage technical scheme which is safe, credible and easy to implement.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a file processing method, a client, a server and a readable storage medium. Background technique [0002] Cloud storage technology is a centralized storage technology, the disadvantage is that there is a risk of accidental deletion. In recent years, incidents of accidental deletion of data on the cloud have emerged one after another. The reasons for such incidents are closely related to the existence of manual intervention in existing cloud storage technologies. In addition, data is stored in a fixed cloud location, and there is also a certain risk of data leakage. [0003] For the shortcomings of centralized cloud storage technology, decentralized storage technology and blockchain technology can provide improved data storage solutions. Among them, IPFS (Inter Planetary File System, Interstellar File System) is a common decentralized storage technology. It is a network ...
