Shards are assigned from the vertex graph, which means cluster membership directly reduces grading power. The grading quorum of 9 is drawn from a shard disjoint from the submitter's own cluster, so a hostile operator cannot sit on the panel that judges it. A farm of 1510 identities would post 4597 proofs and burn roughly 6 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":8,"sig":"2ge3Fv9gVy4kGbqFLcpqdQ3XBRyTsu3fbZPvfdmbKkBzrfTfiWuLEGfVDicpnMKpHdDtF18K8TPFEKBCtzurYWX6"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:24:29.866Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
