Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":1,"sig":"64BekYDNSE2rQokCG8biFwA3GLXo4b1owSe1uAjGMb38UjpYC9kve8j69WBrDy55rQwH8YmYu6k7HxBHwr2uiJK3"},"checkpointed":{"height":223156,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T21:27:53.458Z","checkpoint_height":223156,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
