A luminous verified, unique human with a glowing proof credential
Anti-sybil · proof a real, unique human is behind the account

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, unique, live human, attested by identity + on-device liveness. Pay per check.

Use cases

Where it stops the bleeding

Airdrops & quests

One human, one claim

Block sybil farms from draining token drops, quests and rewards — gate on a verifiable unique-human credential.

Marketplaces

Real buyers & sellers

Cut fake listings and bot accounts; verify the human behind a high-trust action.

Ticketing · dating · reviews

No bots, no scalpers, no fakes

Verify real fans, real people, and real reviewers — without collecting and storing their biometrics yourself.

DeFi · RWA lending

A verified human behind the wallet

As tokenized assets become collateral, gate borrowers and depositors on a wallet-bound, anti-sybil personhood credential — compliance without the PII. Bind a wallet via /api/agents/wallet/challenge; on-chain protocols read isVerifiedHuman(wallet).

FAQ

Questions, answered

What is proof of personhood?+

Verifiable evidence that a real, unique, 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 a unique and live human, and biometrics stay on-device; only a signed attestation leaves.

How do I stop sybils in an airdrop or marketplace?+

Gate the action on a Proof-of-Personhood credential — one verified human, one claim — blocking sybil farms from draining drops, quests, tickets, or reviews.

How much does a check cost?+

Plans: Free (10,000 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.
