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. A farm holding 75 fresh keys therefore burns for 75 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":3,"sig":"2Tj7vm1yu2i6nMcZMGPVxcZAgqkbsPZNbwPmD4iUqLqcpMJ9a2XZ1zb4HcUXUvGXskZVnGGzfC5z9L1hP5AWd4M8"},"checkpointed":{"height":84386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T05:30:54.880Z","checkpoint_height":84386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
