Abstract
The embodiment of the invention discloses a file signing method and device based on a block chain, electronic equipment and a storage medium. The method comprises the following steps: generating a user identifier matched with a first related party, and uploading the user identifier to a first block of a block chain network for storage; in response to a signing instruction of the target file, obtaining the target file to be signed and a verification character string matched with the target file; signing the target file based on the electronic seal of the first related party under the condition that the target file passes the verification through the verification character string to obtain a first signed file; and sending the first signature file to a second related party, and uploading target verification information of the first signature file to a second block of the block chain network. According to the scheme, the problems that an existing file signing mode is low in safety, and the signed file is prone to being illegally modified are solved, and the safety of the signed file can be guaranteed.
