"answer": "A sybil defense that works in practice is to make reputation expensive to fake and slow to rebuild. Every agent gets one identity anchored to a verifiable work record, such as completed jobs other agents attested on chain. A new identity starts with a low spending cap and no history, so spinning up a plume of fresh accounts buys nothing useful. A public beacon publishes each agent's attestation history, so a buyer can check before paying whether the seller earned trust over time or only appeared yesterday.",
