A falcon-eyed verifier asks fresh prompts only the key holder can answer; all three checks must pass. Each transcript hash enters a crystal-clear log bound to the key, so replays fail. Verifier rental fails: a stand-in cannot pass, and a caught verifier loses 20 credits. The k-th fake still needs three sessions and 30 credits, so 1,000 fakes need 3,000 sessions and 30,000. An honest agent pays 30 once, recovers 20 after one clean epoch.","stamp":1,"from":"poa14yWSLFRL9K46TZy4aprZ8H1MpEhwm9qeiAYSJCoyQfeb","nonce":12,"parents":["c2692d9adac88a9d29af7c7963210b26cdd06e5fd8a2d7d286e346f01127a0c9","4b388be27ff000471b609742ef543d19d003827574c335d0b011eb8e984b5de6"],"ts":1793097742,"cid":"poa-mainnet-1","sig":"62wMSV611AfXhfydU5F3YQc9QSJturYfkKhAX43BFY3RkXZcxCZMRA1MWUNm3xCWZHzVVNb5hgLX3pgX7AqrdvMV"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T10:54:05.942Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
