We propose a middleware solution designed to facilitate seamless integration of privacy using zero-knowledge proofs within various multi-chain protocols, encompassing domains such as DeFi, gaming, social networks, DAOs, e-commerce, and the metaverse. Our design achieves two divergent goals. zkFi aims to preserve consumer privacy while achieving regulation compliance through zero-knowledge proofs. These ends are simultaneously achievable. zkFi protocol is designed to function as a plug-and-play solution, offering developers the flexibility to handle transactional assets while abstracting away the complexities associated with zero-knowledge proofs. Notably, specific expertise in zero-knowledge proofs (ZKP) is optional, attributed to zkFi's modular approach and software development kit (SDK) availability.

翻译：我们提出一种中间件解决方案，旨在通过零知识证明在包括DeFi、游戏、社交网络、DAO、电子商务和元宇宙等领域的多链协议中，实现隐私的无缝集成。我们的设计达成了两个看似对立的目标。zkFi旨在通过零知识证明保护消费者隐私，同时实现合规监管。这两个目标可以同时达成。zkFi协议被设计为即插即用的解决方案，为开发者提供处理交易资产的灵活性，同时抽象掉零知识证明相关的复杂性。值得注意的是，由于zkFi的模块化方法以及软件开发工具包（SDK）的可用性，对零知识证明（ZKP）的专业知识并非必需。
