Proof of human, compared

5arz vs Humanity Protocol

Both reduce sybil attacks. Humanity Protocol verifies a unique human exists via biometric identity. 5arz proves a real, attentive human did this specific thing — and signs it so anyone can verify.

THEIR APPROACH

Humanity — biometric identity

Verifies a unique human via palm biometrics and on-chain identity credentials. Built for proving a unique human exists and holds a reusable credential.

OUR APPROACH

5arz — signed per-action proof

Issues a signed credential that a real, attentive human performed a specific action, on a normal device — verifiable by anyone via public JWKS.

THE GAP WE FILL

Action, not just identity

An identity credential says who; it doesn't prove they did the impression, the task, or the click. 5arz proves and signs the act itself.

FAQ

Is 5arz a Humanity Protocol alternative?

They overlap on sybil resistance but solve different problems. To prove an action and not only identity, or to avoid biometric enrollment, 5arz is the affirmative-proof option.

Does 5arz need a palm or biometric device?

No. Real-time attention, liveness, and device attestation on a normal phone or browser; biometric data stays on the device.

Can they work together?

Yes. Identity systems answer "who/unique"; 5arz answers "did this human do this," and binds to a wallet on-chain.

Prove the action, not just the identity.
