Method — Proof Layer

Definition, scope boundary, and structural model.

Definition

Proof layer describes a structural system layer that enables the creation, validation, and persistence of verifiable evidence across digital, physical, and hybrid environments.

It operates between data generation and decision-making processes, ensuring that claims, events, or system states can be substantiated through structured verification mechanisms.

Scope Boundary

Included

Evidence generation and capture mechanisms
Verification and validation structures
Proof persistence and traceability
Cross-system proof interoperability
Linkage between events and verifiable outputs

Excluded

Legal adjudication or enforcement processes
Regulatory interpretation or compliance certification
Operational system implementation guidance
Vendor-specific proof systems
Subjective trust assessment frameworks

Structural Phase Model

Phase 1 — Evidence Capture

A system records an event, state, or claim that requires verification.

Phase 2 — Proof Construction

Captured inputs are structured into verifiable proof formats or attestations.

Phase 3 — Validation

The constructed proof is evaluated against defined verification criteria.

Phase 4 — Persistence

Validated proofs are stored, linked, or made retrievable for future reference.
