Business interaction method and device based on block chain network, equipment and storage medium

Abstract

The invention discloses a business interaction method based on a block chain network, which is applied to a business initiator, and comprises the following steps: when the business initiator is aboutto join in the block chain network, sending information to be verified to a supervisor; receiving first anonymous identity information returned by the supervisor, the first anonymous identity information being anonymous identity information of the service initiator in the block chain network generated based on the first real identity information after the supervisor verifies the to-be-verified information successfully; and after the supervisor uploads the public key of the service initiator and the first anonymous identity information to the block chain network, using the first anonymous identity information to carry out service interaction with the service opponent on the block chain network. By applying the technical scheme provided by the embodiment of the invention, the anonymous transaction of the service initiator on the block chain network is realized, and the security of service interaction on the block chain network is improved. The invention further discloses a service interaction device and equipment based on the block chain network and a storage medium, and the corresponding technical effects are achieved.

Description

technical field [0001] The present invention relates to the field of security technology, in particular to a business interaction method, device, equipment and storage medium based on a block chain network. Background technique [0002] With the rapid development of computer technology and Internet technology, blockchain technology has gradually emerged, and blockchain networks have been increasingly widely used in financial and other fields. [0003] As a distributed public ledger, the blockchain network is jointly maintained by multiple nodes. The information in the ledger is transparent to all participants, such as business initiators and business counterparties. Since the data is open and transparent in the blockchain ledger, the identity information and private information of the participants will be disclosed and cannot be protected once they are uploaded to the chain. [0004] In the current blockchain network, the business initiator uses its own real identity inform...

AI Technical Summary

Problems solved by technology

In this way, it is easy to reveal the real identity of the business initiator, and criminals can easily learn and count business interaction-related information through on-chain transactions, which may easily cause business or other secrets to be leaked, making the business interaction security of the blockchain network lower.
