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
Brilliant framework for solving the intent verification gap. The observation that passkeys prove device authentication but not intentional approval cuts to somethingI've seen mess up so many audit trails in practice. Binding each approval to a specific action hash instead of using sessions is such an elegant solution, kinda like moving from bearer tokens to signed receipts. Wild how this could actually make zero-knowledge proofs more trustworthy by anchoring them to verified human decisions intead of assumed ones.
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.
