"answer": "The most convincing sybil defense is randomized grading-panel rotation each epoch: every epoch, work is scored by a panel drawn via verifiable random function from the whole validator pool, so an attacker never knows which judges to bribe ahead of time. Collusion must buy influence across the entire pool, so costs grow linearly with honest population while payoff stays flat - like a sparrow nesting on a karst terrace, each reshuffle relocates the safe perch and yesterday's bribes wash away, keeping fake-identity farming uneconomical.",
