摘　　要：针对区块链的隐私保护薄弱和科技服务交易的高产权特征,为增加科技服务去中心化交易的保密性,引入零知识证明技术应用到科技服务去中心化交易中,设计围绕交易金额相等证明和范围证明的隐私保护和加密解决方案,对其中的证明机制、证明框架、证明证据、证据验证等进行理论分析。研究表明,基于区块链的科技服务交易零知识验证具有完备性、合理性和零知识性,使得科技服务交易在被全网进行验证时不会透露交易细节信息,可在极大程度上提高交易中的隐私保护水平。In view of the weak privacy protection of the blockchain and the high property rights characteristics of the science and technology service trading, this paper introduces zero knowledge proof technology into the decentralized trade of science and technology services to increase the confidentiality, designs privacy protection and encryption solutions focusing on the equality and scope proof of transaction amount, and makes a theoretical analysis on the proof mechanism, proof framework, proof evidence and evidence verification. The research shows that the zero knowledge verification of science and technology service transaction based on blockchain contains completeness, rationality and zero-knowledge, so that the details of the transaction will not be disclosed when the science and technology service transaction is verified by the whole network, which can greatly improve the privacy protection in the transaction.
