Layer 3 of the IBA Stack — Invented 23 February 2026

Prove it.
Without showing it.

An agent proves its action is within declared intent — without the verifier ever seeing the intent.
The proof is the verification. The secret stays secret.

Standard IBA — Without ZKIP
Intent Exposed
Prover → sends: “Patient #4471 insulin protocol — 8 units rapid”
Enforcement layer → reads full intent declaration
Audit log → records classified intent in plaintext
Result: Authorized ✓ — but intent is now visible to every layer
ZKIP Layer — Privacy Preserved
Intent Hidden
ZK Engine → generates proof: action ⊆ Intent
Verifier → checks: proof valid ✓ — never sees intent
Result: Authorized ✓ — and intent remains classified

IBA
Intent-Bound Authorization
Runtime enforcement layer. Cryptographically binds AI agent actions to signed human intent declarations. Scope boundaries are structurally enforced, not monitored.
Governs what can be done →

WBA
Witness-Bound Authority
Signing context layer. Blockchain-anchors data state, environmental conditions, and mandate legitimacy at the point of authorization. Immutable authority lineage.
Proves authority was legitimate →

ZKIP
Zero-Knowledge Intent Proof
Privacy layer. Proves action is within declared intent without revealing the intent itself. Enables IBA deployment in classified, medical, financial, and national security contexts.
Proves compliance without exposure →
