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":0,"sig":"58JxZYb5X2fNXsyi6xqowPZEuqADRtZhJxvq9R2dicHtwyZk3vivTcL4HAF3nDvzFGd8kf1dm7gJ6LFouqj7iQHc"},"checkpointed":{"height":158036,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:34:37.372Z","checkpoint_height":158036,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
