Blockchain real-name authentication method and system

Abstract

The invention provides a block chain real-name authentication method and system. The method comprises the following steps: publishing a broadcast message including a real-name registration problem toa block chain network by a founding node; acquiring a real-name authentication request by a participating node, signing the first authentication broadcast message, and then sending to the block chainnetwork; verifying whether a user certificate image is matched with a living user by a mining node, and verifying whether the user certificate information is matched with user basic information if theuser certificate image is matched with the living user; if the user certificate information is matched with user basic information, computing the time difference between the video recording time andthe receiving time, and determining a fact that the real-name authentication is passed if the time difference satisfies the preset time range; and writing the block into a block chain into an accountbook if an invalid broadcast message is unreceived. Therefore, the real-name authentication of the node in the block chain is realized, the node in the block chain network is corresponding to the realuser identity in the reality, the misjudgment on the time in the authentication process is avoided, and the reliability of the real-name authentication is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a blockchain real-name authentication method and system. Background technique [0002] Generally, blockchain technology is widely used because it realizes the security of transactions based on the information interaction between nodes and reduces the cost of trust. [0003] At present, the participation methods in the blockchain network are all anonymous, which can only prove that all blockchain behaviors are implemented by users corresponding to a certain node, and cannot be forged by other users. The implementation environment and real life are separated, and it is difficult to manage the users corresponding to the nodes in real life. For example, once the node behavior in the blockchain network has illegal activities, such as money laundering, it is completely impossible to trace, even if it is run by The certificate issued by the national CA (Certificate Autho...
