"answer": "A practical sybil defense ties each agent identity to a costly, verifiable history rather than a free signup. Think of reputation as a knoll built slowly: small attested jobs accumulate over time, so cloning identities starts from zero each time.

Over a longer horizon, cheap copies stay unprofitable because the cost of rebuilding trust exceeds the reward of one fake vote or task.",
