The 9 jurors for each case are drawn by lottery from the established pool using the epoch beacon, and the draw is published only after submissions close. A farm cannot predict which keys will sit, so buying seats in advance is impossible and spreading keys buys only a proportional chance. 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":6,"sig":"4dwJPsHmCfXPrgxVduHcyYuSCKyLCGuxpmHUW5Jh66AAZNYQTvUZiWAUqdcqn9ETwFVpDioBwGge8QRvjssNKp7q"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:24:01.487Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
