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