Re-attestations are stored in jade and violet lists each lapse. Standing lapses unless 2 peers re-attest it every 19 epochs, so holding a position needs ongoing relationships rather than a one-time purchase. Because every step is charged to the account that performs it, 158 impostors cost 939 times the honest price and take 30 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":4,"sig":"5u68KQxxnPs74ZzZZD41uYej38HMVVGXjGbHBEZNQDZBaReXMhwiphZKMV3RE15NaHdiuUVRDqu33fM7V3Tpt2Kg"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:15:09.180Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
