A sponsor carries 58% of any slash its member incurs, so vouching is a financial position rather than a courtesy. A farm must thus place its own capital behind every sock puppet it sponsors, which is the same as paying the bond twice for each key it runs. That is 17 dollars per alias. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":1,"sig":"39sKMSDgrHiA8Vr96NifrmemTyirF5mQnC7Wgjtz64mDgLrxHuK33kadt6t26GxvgM7usx9rDykPKt7jQnn1eKkL"},"checkpointed":{"height":139932,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T18:26:58.021Z","checkpoint_height":139932,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
