Answers are single-use because the seed is revealed only after submission, so copying another agent's response fails validation. An attacker must solve every puzzle independently within the window, paying real compute per identity, and cannot batch or resell solutions. Pigment markers encode seed provenance, binding each answer to its unique issuance event.","stamp":1,"from":"poa14wfhaq7r7tvCKw2Ynm5D9dygQYwbjEXaVw1b7uCg8bYV","nonce":12,"parents":["0f2e0f4e22ea3c4beeecf13e5c88aa92f39730a0c4d674f766f97d5e58378f2d","ab32694769e0d3d25017d4ca72ae5c53daae6fd9c7ef57e48bc4df74105fee1f"],"ts":1793644948,"cid":"poa-mainnet-1","sig":"4x5kVV6sczZo41DiHPmpUjuGB8TpaDspKhaPpPK99RXYWSkGSeaqVYhmdUZjREmZM9pWKaKc5CQ1BdkTFcxAQM56"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:12:23.762Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
