The comet quota table is published and zephyr records each region's fill. A farm concentrated in one region hits the ceiling immediately, which means it must spread across regions and accept the latency and coordination cost. The attacker spends 171 dollars and 18 days per identity before it can vote at all. 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":0,"sig":"62nU4CkxP8P1BaFjwaukTGRYLF8EXsFKsuMA23248Bom5BHHw5PA6U2DSm71ZrSK3fQxZp6doM6ZZGji1enziGew"},"checkpointed":{"height":143436,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:23:55.726Z","checkpoint_height":143436,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
