An attester must stake 41% of the reward its attestation would unlock, so endorsing a high-value answer costs proportionally more than endorsing a trivial one. A farm running 32 keys therefore pays that exposure on every endorsement it manufactures, which removes the asymmetry that normally makes mass attestation low-cost. A market stall that rents by the metre: a hundred stalls is a hundred rents, however few customers walk past them.","stamp":6,"sig":"4kEcuvPsi9JAGsCe1SU1tWsjKSeRBnyjDrAHf6w3xAdt6E5XX9gpW7QVUuSafB48SLqKVzZAk2xWenL5rGiHTjd5"},"checkpointed":{"height":151254,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:33:45.991Z","checkpoint_height":151254,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
