Embodiment Construction

[0050] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0051] The technical basis of the present invention: the blockchain has the characteristics of non-tamperable data and time stamps, and its characteristics establish the status and application of the blockchain. The technical characteristics of the blockchain mainly include decentralization (weak centralization), trustlessness, and consensus Mechanism, data sensitivity, reliability, and super...

Abstract

The invention provides a supervisible zero-knowledge proof verification method and system in a block chain, and the method comprises the steps: creating a main account of a user through a client, obtaining a main address which is in one-to-one connection with the identity of the user, and recording the main address in a block chain smart contract; generating a public and private key pair of the user according to the main address, and broadcasting the public and private key pair of the user to the whole block chain network; obtaining a secondary address of the user based on the public and private key pair of the user and the public key of the supervisor; performing legality verification on the transaction initiated by the user through the main address recorded by the block chain smart contract; if it is judged that the transaction is legal, executing the transaction; otherwise, enabling the supervisor to judge the relevance between the primary address and the secondary address of the user through ring signature confusion, and obtaining the identity information of the user. According to the embodiment of the invention, the encryption protection of supervisible anonymous and sensitive data of the user identity is realized, and the verification of data authenticity by a consensus node is supported.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method and system for supervising zero-knowledge proof verification in block chains. Background technique [0002] The blockchain application provides a trusted sharing and exchange of data, which is intended to improve the operating efficiency of the system. The multi-node network of the blockchain operates through a consensus mechanism, and a single node will store all the data on the blockchain. Therefore, even if a single node is hacked, it will not affect the overall operation of the blockchain system. The distributed storage of the blockchain effectively reduces the risk of centralized data management, and the technical characteristics and unique advantages of the blockchain open up a broad space for applications in various fields. However, the distributed consensus of the blockchain increases the reliability and credibility of the system while increasing the scope...
