摘要
零知识证明是现代密码学中的基本理论之一,在现代密码学前沿具有广泛的应用场景。随着零知识证明的工业化——简洁非交互零知识的知识论证(zero-knowledge Succinct Non-interactive Argument of Knowledge, zk-SNARK)的诞生,零知识证明在区块链领域得到了强有力的发挥,改进了早期区块链在隐私、效率和存储等多方面的问题,使得区块链能够在现代经济和社会中具有越来越显著的技术先进性。文章综述了零知识证明在区块链中,尤其是在公链项目中具有代表性的应用方式,旨在强调零知识证明等隐私计算技术是未来区块链与实体经济融合,并且发展良好区块链网络生态的必经途径。
Zero-Knowledge Proof is one of the fundamental theories in modern cyptography which can be widely used in application scenarios at the frontiers. Along with the industrialization of zero-knowledge proof, the naissance of zero-knowledge succinct non-interactive argument of knowledge(zk-SNARK), zero-knowledge proof has brought its superiority into full play in the domain of blockchain, ameliorating the existed issues of earlier blockchains in various aspects such as privacy, efficiency and storage, and enabling blockchains to be increasingly technologically advanced in modern economies and societies. This paper makes a survey on some representative applications of zero-knowledge proof in blockchain, especially in public chain projects, and aims to emphasize that privacy-preserving computation technologies such as zero-knowledge proof are a necessary way to integrate blockchains with the real economy and develop a good blockchain network ecology in the future.
