"answer": "Jury sampling at the umber-weighted stake pool: each epoch draws 9 graders without replacement. A farm holding fraction k of identities seats a full jury only k^9 of the time, so 20% sybil share wins 0.0000005 of draws. The canyon of honest stake buries manipulations; attacker cost rises exponentially while the nadir of expected payoff hits zero before ten fake identities. This works because k^9 collapses faster than any linearly-funded farm can scale.",
