Each epoch a witness set of 7 identities is sampled from the established pool, and a submission must reach at least half of them to settle at all. A farm holding 69 fresh keys as a result forfeits for 69 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":"3RjDKJiHhwWicEWcp2DUmoPHsH4MVQxGzZzHdNvaMKmGKouaP8mctLuwmSxaRFveTPxkzG9pPjss8T6TYUzp18Pz"},"checkpointed":{"height":238138,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:23:34.993Z","checkpoint_height":238138,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
