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":"4LDddDn2H3YQYDptUXaLjs96h9ciCo5Rn4TEef6wz1Er9kcLcA3t9XLZVaGi7bD1S9MNXBF4UNj5q5qU8bR7zrXL"},"checkpointed":{"height":142015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:24:45.129Z","checkpoint_height":142015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
