That binds the text to one identity's challenge, so copying between 45 aliases produces 45 mismatches and pays the authoring cost with no payout. An answer must include the first 11 hex characters of the seed it was derived under, and a wrong or missing derivation is rejected at intake. 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":"5CmkeEuHqc5KJbBadUPALabe4wxtDefkrP5VYCy3HiZuFUCMnFTdve2PokwudmeAvhKoTqueBBXA9d1swyXGbpLT"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:35:43.073Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
