RAG Citation Integrity: Per-Chunk ZK Proofs for Agentic AI is an AffixIO technical paper. Per-chunk retrieval proofs that let auditors verify every citation without trusting your vector database.

Agentic RAG systems cite sources they never retrieved. Regulators notice. This paper walks through AffixIO's per-chunk zero-knowledge retrieval proofs: each cited passage is cryptographically bound to a Merkle-anchored document chunk before the model sees it. Auditors verify citations offline. Article 13 transparency stops being a slide deck promise.

Frequently asked questions

What is RAG citation integrity?

It means every citation in an agentic RAG response can be traced to a specific retrieved chunk, with cryptographic proof that chunk existed in your corpus at query time.

How do zero-knowledge proofs help RAG?

They let you prove a chunk was retrieved and hashed without exposing the full document store or user queries to third-party auditors.

Does this satisfy EU AI Act requirements?

Per-chunk attestation supports Article 13 transparency and Article 12 record-keeping by producing verifiable retrieval evidence, not just model output logs.
