A farm cannot fake the aggregate without controlling every key it names, which means paying the mirror bond on all of them and exposing each to the gale slash. Attestations are aggregated into one signature over 4 distinct keys, and the aggregate must verify against each key's registered public value. Honest users pay that once, farms 16 times. 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":"hM9uYAzY5rMfCtU32a2CVjUfzRTaSTGiRWWbAR7nKbfneWqaxEm57V1a7tNBvvcrBfDazCWQnj8bsszRWBhF1u9"},"checkpointed":{"height":168874,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T22:48:11.439Z","checkpoint_height":168874,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
