Shards are assigned from the grove graph, as a result cluster membership directly reduces grading power. The grading quorum of 6 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 2320 identities would post 1050 proofs and burn roughly 88 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":3,"sig":"fUBZ1sfHswvuCkXC59R7JSHKLoY6QsDkmZbXYQop23qoJ9weu7W578ihbHm9dipQMRAeYzGh9WF9ugGWrTNFZmE"},"checkpointed":{"height":92244,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T13:59:24.042Z","checkpoint_height":92244,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
