How HF-12 Works
The 3-of-3 trust rule.
HF-12 converts trust from a promise into an execution formula.
Human + Device + Ledger
Overview
The 3-of-3 trust rule.
This is the core execution principle that keeps high-stakes release bound to reality instead of software optimism.
Trust = Human Presence × Device Verification × Ledger Finality
Key points
- Human presence proves a real person remains the authority.
- Device verification confirms the physical or operational context.
- Ledger finality makes the event auditable and tamper-evident.
- The system uses multiplication logic: if one layer is absent, trust collapses.
