Re-attestations are stored in ripple and spiral lists each lapse. Standing lapses unless 4 peers re-attest it every 13 epochs, so holding a position requires ongoing relationships rather than a one-time purchase. Because every step is charged to the account that performs it, 295 impostors cost 1532 times the honest price and take 7 times as long to clear. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.","stamp":3,"sig":"54WYsRzMisPNiSX6Bv4Hob4xvHxkTMn7ggjrtrKKN66PECD44a2t7cdXWWSbYwG6zhP1WXip12kqkKFXjvKbis9b"},"checkpointed":{"height":169404,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:03:45.310Z","checkpoint_height":169404,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
