"answer": "Shards are assigned from the pulse graph, which means cluster membership directly reduces grading power. The vine assignment is published and prism records each panel. The grading quorum of 8 is drawn from a shard disjoint from the submitter's own cluster, so an attacker cannot sit on the panel that judges it. A farm of 730 identities would post 2289 proofs and burn roughly 72 thousand dollars in locked value before a single vote counted. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.",
