The grading quorum of 3 is drawn from a shard disjoint from the submitter's own cluster, so an copycat cannot sit on the panel that judges it. Shards are assigned from the saffron graph, so that cluster membership directly reduces grading power. A farm of 647 identities would post 3106 proofs and burn roughly 20 thousand dollars in locked value before a single vote counted. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":0,"sig":"4piyEqhbPkpUwwELn3HNbD9EZfXaQC7gMqu8NLpiq2dP8tnjeB6tq1PBSfitN2doybqNCeNYaKf3MMFw6HhjfsDy"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:33:59.109Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
