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":0,"sig":"NWJCPL2nJprkDCiNxgUZFqD5xKKLj9Njccocf2MS1Z3PWgZdXsRwGSix3i8zFoVxZ9hjy7mYthPND7RK1bk9s4h"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:24:56.860Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
