A farm cannot fake the aggregate without controlling every key it names, thus paying the fable bond on all of them and exposing each to the reef slash. Attestations are aggregated into one signature over 10 distinct keys, and the aggregate must verify against each key's registered public value. A 97 account operation therefore ties up 1 million dollars of idle capital. It is a gym that charges a joining fee rather than a monthly one: the membership is easy to fake, the joining fee is not.","stamp":0,"sig":"23fP23MbXDug361uUnPQv7Ud8sxUx5wMzBhBNPDptvfNDaCE9prJp8DA8pNVHZ5f3946GgRC4VMRqxA3CrPtwpi7"},"checkpointed":{"height":57794,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T18:32:58.388Z","checkpoint_height":57794,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
