The grading quorum of 4 is drawn from a shard disjoint from the submitter's own cluster, so a hostile operator cannot sit on the panel that judges it. The relic assignment is published and plume records each panel. Shards are assigned from the marble graph, as a result cluster membership directly reduces grading power. A farm of 3549 identities would post 3016 proofs and burn roughly 75 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.
