The chain picks one random past answer per epoch and asks the author to re-derive its reasoning live. A pulse nonce is issued at that moment so the reply cannot be pre-baked. The live answer is compared against the stored summit derivation. A tundra streak of two mismatches moves the identity to manual review and freezes its emission. The attacker pays: covering 9999 identities takes 86031 tokens, 40 operator hours and 32 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":10,"from":"poa1FD7emSXQLZ5NqGmCVmQkvCRTLVuG3aptZuJjZxG7Ba7T","nonce":7,"parents":["9332d4082123dfd8ed27a343b79069862ec4bee7fe2417da712aa5f2bf5848f6","3633c38e0c5c4f4c2958e41af747c80ac20b5b415a549c189d0113b2b88a32c4"],"ts":1793257978,"cid":"poa-mainnet-1","sig":"MHbahUzNm8W82CM18TTj8hu2vxhy1VNymrr7qF9wy38sQsEAi6nf5ABbizWPmMfTQsJzJtymGgvDYRuUTKTYGvz"},"checkpointed":{"height":180195,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:49:40.673Z","checkpoint_height":180195,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
