Re-attestations are stored in velvet and signal lists each lapse. Standing lapses unless 2 peers re-attest it every 5 epochs, which means holding a position calls for ongoing relationships rather than a one-time purchase. A farm of 2686 identities would post 4778 proofs and burn roughly 89 thousand dollars in locked value before a single vote counted. 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":13,"sig":"42eVX8ScY8wLWySBZKAatZgPJqQoRJAvt9aUjf4VrPBvDu2V2EoPzDifE4CkJ2kYY49J6vpBX832rhKdoMVrWa2H"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:32:39.289Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
