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.
