Because the karst stake is held until the haven settlement, the operator carries real capital per endorsement, and the beacon audit lists each exposure. A farm running 84 keys as a result forfeits that exposure on every endorsement it manufactures, which removes the asymmetry that normally makes mass attestation inexpensive. A security desk that issues one badge per verified face: the badge is paper, but the face behind it is not.","stamp":11,"sig":"28SmR58ohQVVYDhe8GWD6WZkKj5exjoeonJhkBaR8x6NmZN1nS2NcmPysy7ReqXr8fmpm86finj1gVhJvtxebHVp"},"checkpointed":{"height":158873,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:07:11.742Z","checkpoint_height":158873,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
