【摘要】 区块链是一种以密码学算法为基础的点对点分布式账本技术,然而,公开透明的区块链账本辅以社会学挖掘、数据挖掘等统计学方法,使得用户的隐私面临重大威胁,因而隐私保护成为当前区块链技术研究的热点。总结了已有的隐私保护方案,重点聚焦于零知识证明技术,阐述并分析了零知识证明应用到区块链隐私保护方案中的技术挑战,并给出了具有指导意义的解决方案。更多还原

【Abstract】 Blockchain is a peer-to-peer distributed ledger technology based on cryptography,However,open and transparent blockchain ledger,combined with sociological mining,data mining and other statistical methods,brings a major threat to user’s privacy.Therefore,privacy protection becomes a hot issue on the blockchain technology research.The existing privacy protection schemes were summarized,especially focusing on the zero-knowledge proof techniques.The technical challenges in applying zero-knowledge proof to blockchain privacy protection schemes were expounded and analyzed,and position solutions to these challenges were given.更多还原
