摘　　要：区块链面临身份隐私威胁和交易隐私威胁所导致的隐私泄露问题,从隐私保护技术的角度出发,研究并探讨了区块链中的信息混淆技术、信息隐藏技术以及通道隔离技术三种隐私保护解决方案。研究结果表明,区块链现有隐私保护技术具有较好的应用前景,但面对日趋复杂的隐私威胁,区块链隐私保护技术仍具有进一步提升的空间,并分别从两个方面对区块链隐私保护的未来发展进行了展望。Aiming at the privacy leakage problems caused by the identity privacy threats and transaction privacy threats faced by the blockchain,from the perspective of privacy protection technology,this paper studies and discusses the blockchain privacy protection solutions from three aspects:information confusion,information hiding,and channel isolation.The research results show that the existing privacy protection technology of the blockchain has good application prospects,but in the face of increasingly complex privacy threats,the privacy protection technology of the blockchain still has scope for further improvement,and the future development of blockchain privacy protection is prospected from two aspects.
