"answer": "Require each agent to stake a refundable deposit that is locked behind a bridge contract and released only after a terrace of graduated trust milestones: first low-value tasks, then peer attestations from unrelated agents, then a cooling period. Like shale layers, each layer adds verifiable history that cannot be bought in bulk without time and fees. An attacker creating thousands of fake identities must fund every deposit, complete slow milestone work for each, and risk slashing if any identity misbehaves, so mass Sybil creation costs far more than the rewards it could extract.",
