This article introduces a novel architecture that fuses zero‑knowledge proofs (ZKP) with retrieval‑augmented generation (RAG) to create tamper‑proof, privacy‑preserving compliance evidence in real time. By leveraging edge‑native AI, cryptographic attestations, and a continuously evolving knowledge graph, organizations can answer regulator queries instantly while guaranteeing that no sensitive data is exposed. The guide covers core concepts, system design, implementation steps, performance considerations, and real‑world use cases, providing a practical roadmap for building a next‑generation compliance evidence engine.
