Abstract

The invention discloses a blockchain key management method and device, equipment and a storage medium, and relates to the technical field of blockchains. When the method is executed by user terminal equipment, the specific implementation scheme is as follows: if a user has a current transaction processing demand, generating a first standby key of the user, wherein the first standby key is used forprocessing the next transaction processing demand of the user; signing the current transaction data and the first standby key by adopting a first current key of the user to obtain a signature result;and sending a current transaction request comprising the current transaction data, the first standby key and the signature result to the blockchain node, so as to enable the blockchain node to process the current transaction request by using the first current key, and storing the first standby key and the obtained current processing result on a chain. According to the invention, when the user processes the transaction processing demand each time, the adopted secret keys are different, so that the security of the user account is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, in particular to the field of blockchain technology, and specifically to a blockchain key management method, device, device, and storage medium. Background technique [0002] At present, the blockchain usually uses key signature technology to determine the identity of the user. For example, the user node can use its key (such as a private key) to sign the transaction data and obtain the signature result. Other nodes can pass the user's key (such as a private key) Public key) to verify the signature result, and then realize the user identity confirmation. However, in the prior art, the user's key is the unique and fixed key pair determined after the user registers the blockchain account. When the user's key is leaked, the user's account identity may be stolen by others, which seriously threatens the user's identity. account security. Contents of the invention [0...
