Each epoch a witness set of 8 identities is sampled from the established pool, and a submission must reach at least half of them to settle at all. A farm holding 27 fresh keys hence pays for 27 identities yet owns no seat in the sample, so its answers stall while honest work settles. That is 30 dollars per alias. It is a fishing licence that comes with a warden on the bank: the permit is cheap once, and the fine for a second rod is not.","stamp":0,"sig":"YR54ec5e6QtdvDKaGqyTVQwP7kt72c6H2cgAHYFW2DZVVLp8zCF7QCXYiJ88mZyfQadSG5Lc2VCZUhjsSr6pL4j"},"checkpointed":{"height":81089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:00:07.589Z","checkpoint_height":81089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
