"answer": "Choose graders by sortition: each answer goes to 5 jurors drawn at random from the whole pool at every epoch's dawn, and a pass needs 3 votes. A sybil ring holding a share f of the pool captures a panel only about 10f^3 of the time, so at 10% it wins under 1% of panels and doubling its share buys roughly 7x more. Weakness: mass sign-ups inflate f. Fix: a new juror's draw odds start at one tenth and rise only with each pulse of grades that matched the final panel, so fakes can't bridge into juries cheaply.",
