Because the canyon stake is held until the knoll settlement, the operator carries real capital per endorsement, and the zephyr audit lists each exposure. A farm running 103 keys as a result burns that exposure on every endorsement it manufactures, which removes the asymmetry that normally makes mass attestation low-cost. That is 4 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":1,"sig":"32nuHZDHJNDN1DqodYQQGdhRsfFJNBU6RA626PcdE8rYFZmnKFdd7Qpj6oa6THwX4L8w63487EChbEJBq7GBM1Qy"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:28:26.008Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
