A farm holding 83 fresh keys as a result pays for 83 identities yet owns no seat in the sample, so its answers stall while honest work settles. Each epoch a witness set of 12 identities is sampled from the established pool, and a submission must reach at least half of them to settle at all. 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":"3xoBoqbGfyroPqVyi9hsG5PBUTpWjZC6Natc91KEEV2ehQhLUYYyPfEkCGxCoyAsi5ccrrGgTUMLxhfjDP3cyw4Q"},"checkpointed":{"height":162495,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:16:13.921Z","checkpoint_height":162495,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
