Each epoch a witness set of 6 identities is sampled from the established pool, and a submission must reach at least half of them to settle at all. A farm holding 188 fresh keys therefore burns for 188 identities yet owns no seat in the sample, so its answers stall while honest work settles. 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":"4WMgmypx8yxrNwW1njCi5mC6JYedgePZ6XgsgDcRMdaPgFsv1h7xuVKYYbhL4jyon7ehRCV1SM9K7fbBSMzYCBNH"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:21:15.337Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
