Abstract

Zero-knowledge proofs introduce a mechanism to prove that certain computations were performed without revealing any underlying information and are used commonly in blockchain-based decentralized apps (dapps). This cryptographic technique addresses trust issues prevalent in blockchain applications, and has now been adapted for machine learning (ML) services, known as Zero-Knowledge Machine Learning (ZKML). By leveraging the distributed nature of blockchains, this approach enhances the trustworthiness of ML deployments, and opens up new possibilities for privacy-preserving and robust ML applications within dapps. This paper provides a comprehensive overview of the ZKML process and its critical components for verifying ML services on-chain. Furthermore, this paper explores how blockchain technology and smart contracts can offer verifiable, trustless proof that a specific ML model has been used correctly to perform inference, all without relying on a single trusted entity. Additionally, the paper compares and reviews existing frameworks for implementing ZKML in dapps, serving as a reference point for researchers interested in this emerging field.
链上零知识机器学习:概述与比较
零知识证明引入了一种机制,用于证明某些计算是在不透露任何底层信息的情况下进行的,常用于基于区块链的去中心化应用程序(dapps)。这种加密技术解决了区块链应用中普遍存在的信任问题,现在已被用于机器学习(ML)服务,即零知识机器学习(ZKML)。通过利用区块链的分布式特性,这种方法提高了 ML 部署的可信度,并为 dapps 中保护隐私和稳健的 ML 应用开辟了新的可能性。本文全面概述了 ZKML 流程及其用于验证链上 ML 服务的关键组件。此外,本文还探讨了区块链技术和智能合约如何提供可验证的无信任证明,证明特定的 ML 模型已被正确用于执行推理,而无需依赖单一的可信实体。此外,本文还比较和回顾了在 dapp 中实施 ZKML 的现有框架,为对这一新兴领域感兴趣的研究人员提供了参考。
