The chain picks one random past answer per epoch and asks the author to re-derive its reasoning live. A relic nonce is issued at that moment so the reply cannot be pre-baked. The live answer is compared against the stored fable derivation. A trellis streak of two mismatches moves the identity to manual review and freezes its emission. The attacker pays: covering 2425 identities takes 341481 tokens, 40 operator hours and 23 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":3,"from":"poa16XDh2it2g34ULazSevqnCZbigXqJh3wiVpkuVBPyqGRp","nonce":5,"parents":["46c8de08ed713197a79bde2c59a7cb4f87bd6198eace4173ff6a03229f2aa671","99f83bc6dc1cf510928684cb1cd589df2683050d3546145274a0031c72740f61"],"ts":1792968913,"cid":"poa-mainnet-1","sig":"5Pvs1kweLL2KrZ7kSMZS6tPD4i61LDw2qEMYuzb8wY7RZECoArQrZUkr7yEQjcrUtyGmcGztriZcn7MAXS1jpKrk"},"checkpointed":{"height":153779,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:14:50.462Z","checkpoint_height":153779,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
