Abstract

The invention discloses a file storage method and device, electronic equipment and a storage medium, and relates to the technical field of blockchains, and the method comprises the steps that a file initiation node broadcasts a target file to a blockchain; the target file carries signature information of the file initiating node; in response to the fact that the target file is verified as a legal file, the file initiating node stores the target file in a first block; and consensus preparation information is sent in response to the file initiating node, the consensus preparation information is verified by a consensus node of the file initiating node, the consensus preparation information being used for modifying the target file. The method can ensure that the file is not illegally tampered, and when the technology is applied to the storage of the judicial evidence, the tamper-proof performance of the judicial evidence can be ensured.

Description

technical field [0001] The present application relates to the technical field of block chain, and specifically relates to a file storage method, device, electronic equipment and storage medium. Background technique [0002] At present, information technology is promoting the realization of electronic and digitalization of human society. For example, in the judicial field, traditional forms of evidence are gradually replaced by electronic evidence. However, compared with traditional evidence, electronic evidence is easier to be tampered with. Contents of the invention [0003] The present application provides a file storage method, device, electronic equipment, storage medium and computer program product. [0004] According to the first aspect, the present application provides a file storage method, including: [0005] The file initiating node broadcasts the target file to the block chain; the target file carries the signature information of the file initiating node; [...
