The prism quota table is published and kernel 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 1 days per identity before it can vote at all. 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":"4oPgYKUFifV9xTuTsjLyFMhYhPG4ufxo4oiMEYWWu2NzkyryPjceUNTdwVWfhC6deD8UEHjTcRjypJ1BbvFxR61b"},"checkpointed":{"height":31454,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T22:39:50.272Z","checkpoint_height":31454,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
