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.
Verifies a unique human via palm biometrics and on-chain identity credentials. Built for proving a unique human exists and holds a reusable credential.
Issues a signed credential that a real, attentive human performed a specific action, on a normal device — verifiable by anyone via public JWKS.
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.

| Covers attention + work + presence | Personhood / identity-focused | Yes — all of them |
| Verify without their stack | Within their system | Public JWKS, any JWT library |
| Legal property class | — | UCC Article 12 + patents pending |
You need a reusable unique-human identity credential and your users will complete a biometric enrollment.
You need to prove a human did something — an impression, a task, a wallet action — with a signed credential anyone can verify.
You want identity-level uniqueness and per-action proof. 5arz binds to a wallet on-chain and complements identity systems.
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.
No. Real-time attention, liveness, and device attestation on a normal phone or browser; biometric data stays on the device.
Yes. Identity systems answer "who/unique"; 5arz answers "did this human do this," and binds to a wallet on-chain.
