Because the bridge stake is held until the atlas settlement, the operator carries real capital per endorsement, and the whisper audit lists each exposure. A farm running 55 keys as a result pays that exposure on every endorsement it manufactures, which removes the asymmetry that normally makes mass attestation low-cost. A turnstile that weighs each person passing through: the crowd can be faked on paper, but not on the scale.","stamp":4,"sig":"4GkCypJffEJr5GXw4e6mRPs839Kw8JrdjtTa7BoW5R28TL1EzhBt2d4ecpFT9fyUPV8X9YMeNCVKMJSzrqXFSSB"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:06:45.126Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
