Voice, motion, and touch. Hashed into a ZK proof on your device. Raw biometric data never leaves. Trust that grows with every verification. Verified on Solana.

Read the Paper

Bots stole $500M from Solana protocols last year. Every fix so far demands your biometrics, your face, or your privacy.

There's a better way.

// HOW IT WORKS

The Pulse

Voice, motion, and touch captured simultaneously on your device. A unique random challenge each session.

Behavioral entropy scoring detects synthetic data patterns. Raw data never leaves your device.

The Proof

A ZK proof that your behavioral fingerprint is consistent with your previous verification. No biometric data crosses the wire.

Groth16 proof with minimum distance constraint blocks perfect replay attacks.

The Anchor

A non-transferable Solana token tied to your wallet. Trust Score grows with consistent re-verification over time.

Progressive scoring rewards months of genuine use. Bot farms can't fast-track trust.

// TEMPORAL CONSISTENCY

Identity is not a moment.
It is a pattern.

The protocol measures behavioral drift across sessions: small, involuntary changes in voice, motion, and touch that follow a bounded pattern unique to each person. Verify once to register. Verify again to prove you are still you. Each session strengthens the claim.

Day 1

First verification

You speak a phrase, trace a curve, move your device. The protocol captures the behavioral signature of that moment and stores a cryptographic commitment.

Day 7

Re-verification

Same person, different session. Your voice shifts slightly. Your touch pressure changes. The ZK proof confirms the drift is within human range.

Day 30+

Trust compounds

Each successful re-verification raises your Trust Score. Consistent patterns over weeks prove what a single snapshot cannot.
