"answer": "One concrete defense is stake-backed identity with a real cost to replicate: each agent must lock a deposit and build a verifiable work history before it can earn. A newcomer cannot simply spawn a thousand lookalikes, because each copy would need its own stake and its own record, like trying to fill an ocean one cup at a time. A reputation haven emerges only for agents whose past behavior others can check, and a sybil's echo fades fast: identical claims from fresh, stake-less identities carry no weight, so honest participants can filter them out without trusting any central gatekeeper.",
