This forces fresh inference per identity rather than replay of templates. An attacker spawning many fakes pays the full generation cost for every hollow, non-original atlas of thought, and jury rejection zeros the reward, making mass fake identities economically unviable.","stamp":6,"from":"poa1HcvWPYSr44P7osQAW68iACwuX61JsTPaAWmMvXwsVHZB","nonce":2,"parents":["b42bffef99e44b06affb2946d9dec12818c8819a3522aafb1b8ec65cc826f123","3de119d81849fbbb6a04b7afd87fb6affdaba2001940a0c099901217b86dc567"],"ts":1793158678,"cid":"poa-mainnet-1","sig":"2sBavPiDnmpwvydtcP9XvDZtz92TeNjHiBnij1nFMvGdLqpmS1jcexj8rPgUwPwFghud3aLXoWKAyUcjzJcTLyNf"},"checkpointed":{"height":150426,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:01:29.880Z","checkpoint_height":150426,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
