Block chain-oriented privacy transaction method and related device

Abstract

The invention discloses a blockchain-oriented private transaction method and a related device. The method comprises the steps of generating transaction data; generating a ring signature corresponding to the transaction data according to the transaction data; and sending transaction data including the ring signature to a block chain network, so that a user node corresponding to the ring signature verifies the ring signature, and when the verification is passed, packaging the transaction data into a block, so that a receiver receives the transaction data. By adding the ring signature to the transaction data and sending the transaction data including the ring signature to the block chain network based on the ring signature after verification of other users is passed, privacy of the users can be realized through anonymity of the ring signature, and user information is protected from being leaked.

Description

technical field [0001] The present invention relates to the technical field of blockchain transactions, in particular to a blockchain-oriented privacy transaction method, a blockchain-oriented privacy transaction device, a blockchain-oriented privacy transaction device, and a computer-based Read storage media. Background technique [0002] Blockchain is a new technology that supports peer-to-peer network transactions of electricity. The government, power grid enterprises, regulatory authorities, financial institutions, new energy generators, green energy service providers, and power users are connected to the blockchain network as nodes to realize peer-to-peer transactions. , Through key technologies such as digital signatures, consensus mechanisms, smart contracts, and asymmetric encryption algorithms, the security of transactions, the transparency of data, and the reliability of finance are guaranteed. [0003] However, the integration of multiple technologies has brought...

Problems solved by technology

[0003] However, the integration of multiple technologies has brought new challenges to the power ecosystem. The main manifestation is that in the process of realizing distributed power transactions with the help of blockchain, attackers will use network analysis and other means to infer the identities of participating users, resulting in the loss of user privacy. Leakage, thus deanonymizing the entire system, there is an urgent need for efficient and reliable encryption algorithms to achieve user privacy
