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":"5LSVypcQtCfiNLoqSAivqV5T4gMDx6c7JE63gKwLKWbkeQg1jcKWTewHmLfaDjHisxvjoWm2UY3gmCC1pLTVUurk"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:57:33.550Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
