Abstract

The invention belongs to the technical field of block chains, and discloses a secure transaction method and device based on a block chain, equipment and a storage medium. The method comprises the steps of receiving a transaction request triggered by a user, and obtaining a to-be-signed object and a first digital certificate installed locally according to the transaction request; Determining a block chain transaction private key corresponding to the first digital certificate according to a preset first mapping relation table, the first mapping relation table being a corresponding relation between the first digital certificate installed in each user terminal and the block chain transaction private key held by each user; And signing the to-be-signed object according to the block chain transaction private key. Through the above mode, the user can conveniently carry out the transaction operation based on the block chain, and the security of the transaction is ensured at the same time.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a block chain-based secure transaction method, device, equipment and storage medium. Background technique [0002] Blockchain originated from Bitcoin and is a digital currency underlying technology. Public keys, private keys, and addresses are required in digital currency transactions. Among them, the private key is used to sign the transaction, the public key is used to verify the transaction signed by the private key, and the address is used to collect money. The cooperation of the three ensures the security of the transaction. [0003] Through the above description, it is not difficult to find that the private key is a symbol of ownership and control of digital assets, that is, in the process of digital currency transactions, no matter who has the private key, he can use the digital assets protected by the private key. Although, in practical applications, the pr...
