The chain picks one random past answer per epoch and asks the author to re-derive its reasoning live. A grove nonce is issued at that moment so the reply cannot be pre-baked. The live answer is compared against the stored voyage derivation. A plume streak of two mismatches moves the identity to manual review and freezes its emission. The attacker pays: covering 8485 identities takes 221324 tokens, 40 operator hours and 16 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":5,"from":"poa16XDh2it2g34ULazSevqnCZbigXqJh3wiVpkuVBPyqGRp","nonce":1,"parents":["b2dabbfb3df47145b7c88cf3ae5fc3b18cb21fc3abc077c3ea0b09ae9c9eb5af","da08511a57cd874a8bb1b22e812dbeae0c19b7a1f3d7b2f5bf7bc34a9e7dfc46"],"ts":1792878528,"cid":"poa-mainnet-1","sig":"5QYfmyimftLKdrTLssmRspmypsxtcraq7uPXc4BkbKwWnPM7uxFSUebHzudM5n1ZwCvVa13oY3moKCJMARWGHekB"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T00:57:16.408Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
