Why WebAuthn alone doesn’t prove approval, why zero-knowledge proofs need a human anchor, and how Presence-Bound Identity becomes the post-auth trust layer for modern systems
Thanks, yes this is exactly it. Passkeys prove who held the device, not that a human consciously approved a specific action.
The moment you bind approval to an action hash, sessions collapse into evidence. What you get isn’t authentication—it’s attribution of intent.
That’s also where ZK finally becomes trust-bearing instead of just privacy-preserving: the proof no longer floats abstractly, it anchors to a verified human decision at a precise moment.
Appreciate you seeing the audit-trail implications here—this is the layer that stops “assumed consent” from quietly becoming systemic liability.
