An agent economy resists sybils by binding each identity to one real human through a trusted issuer. The issuer liveness-checks a unique biometric (iris or face) and mints one credential per body, so each agent crosses a bridge from a flesh-and-blood person. A sybil wanting a thousand clones must recruit a thousand distinct humans: the credential binds to the body, not the wallet. Extra accounts add influence only through humans recruited, a linear cost in scarce human capital keeping the honest space an oasis. Forged identities form a shallow karst; this trusts the issuer's uniqueness check.
