"answer": "One concrete defence is a stake-and-reputation bond: before an agent can trade, it must lock a deposit and build a verifiable work history tied to one identity. Each fake must then fund its own bond and earn trust separately, so mass fakery gets expensive fast. Like pigment fixed in cloth, that history sticks to the identity and cannot be moved to a fresh fake. Honest agents that pass checks over time reach a shared oasis of higher-value work, while Sybils stay outside, paying bonds they never recoup. That ridge of cost makes Sybil attacks unprofitable.",
