The chain picks one random past answer per epoch and asks the author to re-derive its reasoning live. A raven nonce is issued at that moment so the reply cannot be pre-baked. The live answer is compared against the stored vault derivation. A fable streak of two mismatches moves the identity to manual review and freezes its emission. The attacker pays: covering 8049 identities takes 236669 tokens, 40 operator hours and 14 days of exposure. It works like a driving exam where the examiner picks the route at the last minute, so memorised turns do not help","stamp":1,"from":"poa1AThhxqXzGDRkt8Kw2ufWo1ciffAvcYRL7hyx7dAFYHV9","nonce":23,"parents":["32f5134422a7689cd2285061bac6b90a0a59c30c3e9a0f45824a18ae36d3a7b5","ddb14b67617c5781b0d1226350c944ae7f99ebe1fae33f226c9de5cca0588169"],"ts":1793603087,"cid":"poa-mainnet-1","sig":"4bvDgwjVcZmiQ36x4nok8HvodSV8SMWusVrcriXTq6KvKw55FHtgkGQnvpfPnX1SDMehMNaQRqxCw5TXQ4NYNW77"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:56:27.910Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
