Is this a real human?
Now you can prove it.
Bots and sybils drain airdrops, fake reviews, scalp tickets and flood marketplaces. 5arz issues a cryptographically verifiable Proof-of-Personhood credential — a real, ID-verified, live human, attested by identity + on-device liveness. Pay per check.
Where it stops the bleeding
One human, one claim
Raise the cost of farming token drops, quests and rewards — gate on verifiable proof that an ID-verified, live human is behind each claim.
Real buyers & sellers
Cut fake listings and bot accounts; verify the human behind a high-trust action.
No bots, no scalpers, no fakes
Verify real fans, real people, and real reviewers — without collecting and storing their biometrics yourself.
A verified human behind the wallet
As tokenized assets become collateral, gate borrowers and depositors on a wallet-bound personhood credential — compliance without the PII. Bind a wallet via /api/agents/wallet/challenge; on-chain protocols read isVerifiedHuman(wallet).
How it's different from face/iris "proof of human"
| Iris/face proof-of-personhood | 5arz | |
|---|---|---|
| Hardware | Special orb / face scan | None — phone + standard identity check |
| What's proven | Unique biometric identity | Unique + live human, identity-backed |
| Biometric data | Often centrally enrolled | Stays on-device; only a signed attestation leaves |
| Bonus | Personhood only | Same human can also carry Proof-of-Human-Fulfillment for actual work |
Patent distinction: 5arz verifies a live human (and their work), not just a static biometric. US 63/979,052 + 63/979,474.

Questions, answered
What is proof of personhood?+
Verifiable evidence that a real, ID-verified, live human — not a bot or duplicate — is behind an account. 5arz issues it as a signed credential, backed by identity + on-device liveness.
How is this different from orb / face-scan personhood?+
No special hardware — just a phone and a standard identity check. We prove an ID-verified and live human, and biometrics stay on-device; only a signed attestation leaves.
How do I raise the cost of farming in an airdrop or marketplace?+
Gate the action on a Proof-of-Personhood credential — every claim is bound to a government-ID-verified, live human with a stable per-account reference you can rate-limit on. The credential does not assert cross-account uniqueness — pair with your own duplicate controls for strict one-per-person gates.
How much does a check cost?+
Plans: Free (1,000 seals/mo + 10 document checks, no card), Starter $99/mo, Growth $499/mo, Scale $2,499/mo. A human never pays to complete their verified human profile.
