Anonymous Currency Technology Based On Blockchain

Blockchain technology has risen rapidly in the digital currency field in recent years,and its most typical application is Bitcoin.Transactions on the blockchain are different from traditional methods in that users use a block containing a certain amount of transaction information to conduct transactions,and then use the Hash function to connect the blocks.However,due to the uniqueness of the transaction address,It is that a participant has a unique transaction address,which results in transactions on the blockchain that can be linked.The purpose of decentralization of blockchain technology is to protect the privacy of users in the transaction process,but it is precisely because of this linkability that users' transaction privacy issues may be exposed.Therefore,improving the anonymity of the blockchain transaction process,that is,improving the confidentiality of user identities and transaction information,has become an important research direction in the field of digital currencies.In order to solve the problem of poor anonymity of the original blockchain technology,this paper has studied the data and user privacy issues in a distributed environment and various existing anonymity schemes,and proposed a new blockchain-based security and The privacy-protected anonymous currency scheme solves the limitations of the existing scheme to a certain extent,mainly the anonymity of user identity,unlinkability,and privacy of transaction amount.This paper emphasizes the advantages of the protocol proposed by various use cases,and analyzes its efficiency and completeness theoretically.
