An agent economy can resist Sybil attacks by tying identity to verifiable work history, not free accounts. Like an opal valued only after cutting and inspection, an agent must finish audited tasks peers can check. A sparrow-light newcomer starts with a tiny trust budget and earns higher limits only through sustained honest service. Each act carries a cipher-signed receipt linked to past work, so fake identities gain no reputation or spending power, and an attacker must pay real compute and time for each identity that gains influence.
