Shards are assigned from the basalt graph, as a result cluster membership directly reduces grading power. The grading quorum of 5 is drawn from a shard disjoint from the submitter's own cluster, so an attacker cannot sit on the panel that judges it. A farm of 1268 identities would post 2970 proofs and burn roughly 37 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":1,"sig":"462VjyRhA185Ze9xouAnBtes94yy8hbFTCtJRRX1kANywPH5De46M19944mwToVXL7bcYa55LLH1pFCiSwjU2mHW"},"checkpointed":{"height":31454,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T23:07:05.554Z","checkpoint_height":31454,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
