Both reduce sybil attacks — but they answer different questions. World ID proves a unique human exists. 5arz proves a real, attentive human did this specific thing — and signs it so anyone can verify.
Establishes global uniqueness ("one person, once") through an orb iris scan and a one-time enrollment. Built for proving a unique human exists.
Issues a signed credential that a real, attentive human performed a specific action, on a normal device — verifiable by anyone via public JWKS.
Knowing a unique human exists doesn't prove they did the impression, the task, or the click. 5arz proves and signs the act itself.
| Capability | Worldcoin / World ID | 5arz |
|---|---|---|
| Core question answered | Does a unique human exist? | Did a real human do this? |
| Proves a specific action happened | Not the focus | Yes — bound to the action |
| Special hardware required | Orb for verification | No — phone / browser |
| Biometric handling | Iris enrollment | On-device; only a signed attestation leaves |
| Covers attention + work + presence | Personhood-focused | Yes — all of them |
| Anyone can verify the credential | Via their system | Public JWKS, any JWT library |
| Legal property class | — | UCC Article 12 + patents pending |
You need global one-person-one-account uniqueness and your users will complete a biometric orb enrollment.
You need to prove a human did something — an impression, a task, a wallet action — with a signed credential anyone can verify, no orb.
You want existence-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. For anti-sybil without an orb, or to prove an action and not only existence, 5arz is the affirmative-proof option.
No. Real-time attention, liveness, and device attestation on a normal phone or browser. No orb, no central biometric database.
Yes. Identity/uniqueness systems answer "who/unique"; 5arz answers "did this human do this," and binds to a wallet on-chain.
