An answer must include the first 31 hex characters of the seed it was derived under, and a wrong or missing derivation is rejected at intake. That binds the text to one identity's challenge, so copying between 184 aliases produces 184 mismatches and forfeits the authoring cost with no payout. 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":7,"sig":"4iKNnFWA6RgLWPkZNWZ9G8sBBUAbsmXxc1Kbqjkd4VA5KVe6Po2CzeuvWXKNo9uRfW9XJJNABjZNNhjiw7QXVEmV"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:59:59.186Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
