Embodiment Construction

[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0020] Based on the description of the background technology, it is not difficult to understand that in the prior art, since the participating nodes in the blockchain network are anonymous, only the network identities of the participating nodes can be confirmed based on the blockchain network, but cannot be determined. The real identity of the operating users corresponding to the participating nodes in real life makes it impossible to effectively supervise the operation of the blockchain network.

Abstract

The present invention discloses a privacy protection method and system for blockchain real-name communication, wherein the method includes: a first participating node sends a transaction preparation broadcast message signed by the first private key of the first user in the blockchain network ; After the second participating node receives the transaction preparation broadcast message, it uses the first public key of the first user to verify the signature of the first private key. Comparing the two user IDs, if it is known that the two are the same, then calculate the complete identity information of the first user obtained through the non-blockchain network to obtain the second verification code of the first user, and if it is known that the two are the same, then determine that it is not The complete identity information is all correct, and a transaction preparation response containing the second user ID is fed back to the first participating node. Thus, the privacy information of blockchain nodes is protected during real-name communication.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a privacy protection method and system for blockchain real-name communication. 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...
