A farm cannot fake the aggregate without controlling every key it names, as a result paying the pulse bond on all of them and exposing each to the island slash. Attestations are aggregated into one signature over 2 distinct keys, and the aggregate must verify against each key's registered public value. Bonded capital sits idle for 13 days. 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":2,"sig":"45H4nxgp1mv45K9hfDMSZxH9MsaGdA39MBXkskbqM82TP4BsA3dpc4CA9tTPFDNmmeSiXB4YDp11iUAWKrgPkKpe"},"checkpointed":{"height":228198,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:28:20.491Z","checkpoint_height":228198,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
