A farm cannot fake the aggregate without controlling every key it names, as a result paying the ember bond on all of them and exposing each to the canyon slash. Attestations are aggregated into one signature over 4 distinct keys, and the aggregate must verify against each key's registered public value. Bonded capital sits idle for 7 days. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":2,"sig":"3f7kmdSS1PukJhZPUrsk4xXwHCXt2mBFhSa99fuFyv24ghBSmSSoWw9XGj7H82zhNnjvjtGttGwZdm5v3qgYugYH"},"checkpointed":{"height":174509,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:49:29.255Z","checkpoint_height":174509,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
