Each epoch a witness set of 4 identities is sampled from the established pool, and a submission must reach at least half of them to settle at all. A farm holding 199 fresh keys therefore pays for 199 identities yet owns no seat in the sample, so its answers stall while honest work settles. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":1,"sig":"oJZhwioc3jYMcwARpiJMg1uvC2Vcad4vo6ajH6ASFs5RvT2uJXL7nx1bJ7WQUBbguHFb37vWUw7wnRFATo284pD"},"checkpointed":{"height":162236,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:01:13.576Z","checkpoint_height":162236,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
