Proof of Humanhood, at the speed of the web.

A browser-native assurance engine that lets a contributor reach value at 0 ms and 0 clicks, and asks for the face once, ever. Legitimate contributors stopped before they started: recovering 10% → 86% conversion without ever trading privacy.

LoA 1 / 4

Step up → LoA 2

LoA 4 Sovereign Enclave Anchor once · ≤15 s ~90% of offered
LoA 3 Passive Biometrics 2.2 s · 1 permission 87%
LoA 2 Hardware Passkey 1 click · <400 ms 93%
LoA 1 Behavioural Humanhood 0 clicks · passive 98.5%
LoA 0 Passive Ambient 0 ms · 0 clicks 100%

Value precedes the ask. No camera before value accrues — and the face is asked for once, ever.

Zeroization probe

Biometrics destroyed in local RAM. Zero data leaves your device.

Probe reported: yes
Non-zero bytes: 0
Retention: none (no template, no frame)

The behavioural rule, adopted as law

Value must precede the ask.

Legacy YID put the most invasive ceremony at step one, before any value. Reordering raises conversion without reducing total ask or total value.

Legacy gate	Legacy loss	Web YID
Desktop → mobile QR hand-off	−42.0%	eliminated
Native app download (~120 MB)	−68.0%	0 MB · never

Assurance elasticity · ADR-011

Friction is paid only where value demands it.

Action class	Required LoA	Value ceiling
Sandbox task	LoA 0	≤ $5
Crowdsourcing task	LoA 1	≤ $25
Routine payout	LoA 2	≤ $500
High-value payout	LoA 3	> $500
Treasury / delegation	LoA 4	unbounded

Requirements are data, never code. No action may demand more than LoA 4, and no camera may open before value accrues.
