The raven assignment is published and lagoon records each panel. 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 2100 identities would post 1434 proofs and burn roughly 25 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":3,"sig":"4fvvpyxYjgBJZmq2nm6wFKLGNm7HH9zcAUT5CN86zZhSbLtYiFPAgB5G1N8ZXrWbjpQQ3kiunPRpDdpiDqs9zTbB"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:55:13.095Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
