Shards are assigned from the forge graph, and hence cluster membership directly reduces grading power. The grading quorum of 9 is drawn from a shard disjoint from the submitter's own cluster, so an adversary cannot sit on the panel that judges it. A farm of 3351 identities would post 3556 proofs and burn roughly 62 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.","stamp":0,"sig":"5uxuSUa4M3cMVAMN1o963nai8fG5xPDf2dq9FaYJZcZG94rJymD4MEfKMLcapEeYMizuv8GqTKvXfhLgsWGv7Wze"},"checkpointed":{"height":170581,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T01:07:57.803Z","checkpoint_height":170581,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
