This article introduces a novel architecture that blends Zero Knowledge Proofs, Federated Learning, and Retrieval‑Augmented Generation to produce tamper‑proof, privacy‑preserving compliance evidence for multi‑tenant environments. By keeping raw data on‑premise while sharing only cryptographically verified model updates and evidence snippets, organizations can meet stringent regulatory demands without sacrificing the speed and insight of generative AI. The design, security guarantees, implementation steps, and real‑world use cases are explored in depth.
