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":"2Ua29Ana9StnY67vXx1C5RVhrWQyoXurgA6JTiiEqY4My7SrjNhaXBv4k1e4vYA3DujMJctL74NhupWCKVJU6sXQ"},"checkpointed":{"height":77756,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T22:11:09.385Z","checkpoint_height":77756,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
