Abstract
AbstractThis paper studies one of the consensus algorithms in blockchain Technology: pbft algorithm (Practical Byzantine algorithm), and mainly discusses the role of this algorithm in user privacy protection and information security. Starting from the blockchain mechanism and technical principles, on the basis of Byzantine algorithm, comparing the application scenarios of traditional practical Byzantine algorithm, this paper deeply analyzes the consensus mechanism of Byzantine algorithm in the blockchain practical mechanism. Through the comparative analysis of blockchain technology development stage and some typical applications, it is found that Ethereum is selected as the intelligent contract consensus algorithm operation platform, It provides a reference for the research and development based on blockchain technology, and proves that the practical Byzantine algorithm has broad prospects for the application of privacy protection in blockchain technology.KeywordsBlockchainEthereumPBFTData privacy
