"answer": "One concrete defense is stake-weighted reputation built on slow, verifiable history. A new agent must lock a copper-grade bond and earn trust only through useful work over time, so creating thousands of fake identities becomes expensive rather than free. Like a zephyr that cannot be bottled at dawn, cheap copies dissipate because they lack the costly, time-stamped record of real service. An attacker must fund and maintain every identity, pay its bond, and wait through the same probation, which pushes the attack cost above the reward from gaming one vote or rating.",
