Embodiment Construction

[0092] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0093] Before introducing the blockchain file sharing method, device, storage medium and electronic equipment provided by the present disclosure, the application scenarios and related terms of each embodiment of the present disclosure will be introduced first. The blockchain is a decentralized distributed database system that is jointly maintained by all nodes in the blockchain network. It consists of a series of data blocks generated based on cryptographic methods, and each data block is a block in the blockchain. blocks. According to the order of generation time, the blocks are linked together in an orderly manner to form a data chain, which is vividly cal...

Abstract

The invention relates to a blockchain file sharing method and device, a storage medium and electronic equipment. The method comprises the steps: encrypting a source file according to a target encryption mode under the condition that the method is applied to a file sender; segmenting the encrypted source file to obtain at least one segmented file; uploading the segmented file to a block chain network for storage, wherein the segmented file comprises an identity verification sequence generated based on an encryption key, the identity verification sequence is used for a file receiver to verify whether the received file is the segmented file or not, and the encryption key is a key used by the target encryption mode. According to the scheme, the file uploaded to the blockchain is encrypted, sothat other blockchain nodes cannot obtain detailed information of the file except the specified file receiver, and authority management of the file on the blockchain is realized.

Description

technical field [0001] The present disclosure relates to the technical field of block chains, in particular, to a block chain file sharing method, device, storage medium and electronic equipment. Background technique [0002] Blockchain is a technology that can collectively maintain a reliable database through decentralization and trustlessness. It can store transactions that occurred within a period of time in units of blocks, and use cryptographic algorithms to connect the blocks in chronological order to form a data structure similar to a chain. Since blockchain technology has the characteristics of distributed ledger, decentralization and non-tampering, it has high application prospects in many aspects. [0003] In related scenarios, the blockchain nodes can share files based on the blockchain network. However, since the distributed ledger must be verifiable to all nodes, the ledger needs to be open to all nodes, which makes file permission management more difficult. ...
