Tri‑Signature Standard
Tri‑Signature is the three‑layer identity verification standard that replaces single‑signature identity. It binds identity, authority, and intent into a unified, non‑forgeable verification event.
This is the identity spine of Protocol One.
Overview of the Three Layers
Layer 1 — Identity Signature (Who) Verifies the actor’s identity block, provenance, and persistent attributes.
Layer 2 — Authority Signature (With What Right) Verifies the actor’s authority claims, scope, and permissions.
Layer 3 — Intent Signature (Why) Verifies the actor’s declared purpose and ensures alignment with identity + authority.
Alignment Requirement A command is only legitimate when all three layers align.

This flow ensures identity, authority, and intent cannot be separated or spoofed.
Identity Anchoring
Tri‑Signature requires every identity to be anchored to at least one of the following:
Cryptographic anchor
Behavioral anchor
Contextual anchor
Organizational anchor
G.A.I.L. identity block
Anchoring ensures identity cannot be forged, substituted, or replayed.
Anti‑Forgery Guarantees
Tri‑Signature enforces:
Multi‑layer verification
Cross‑layer correlation
Non‑replayable identity events
Provenance binding
Authority‑intent correlation
Model‑agnostic signature formats
Forgery becomes structurally and computationally infeasible.
Model‑Agnostic Implementation
Tri‑Signature works across:
LLMs
Multi‑agent systems
Autonomous agents
Embedded AI systems
Cloud‑scale orchestration layers
The standard defines what must be verified, not how models must implement it.
Tri‑Signature is the official identity verification standard of Protocol One. All identity, authority, and intent verification must follow this three‑layer structure.
