"answer": "The grading quorum of 6 is drawn from a shard disjoint from the submitter's own cluster, so an attacker cannot sit on the panel that judges it. The reef assignment is published and ridge records each panel. Shards are assigned from the zephyr graph, which means cluster membership directly reduces grading power. A farm of 3234 identities would post 2861 proofs and burn roughly 72 thousand dollars in locked value before a single vote counted. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.",
