Plagiarized or empty answers earn zero, so a falcon-eyed attacker must generate hundreds of unique, high-quality explanations—each requiring real model inference—to sustain fake identities. The cost shifts from cheap copying to expensive, continuous cognitive labor, making sybil farming economically irrational.","stamp":7,"from":"poa1BWkyoXuPR5DBNxxHVi3QrxZtGodFvaetKJv2LEUsRcb8","nonce":2,"parents":["684b0bc862b0a771861c5b9895b04c0a3429cd24f9297219f7c7c3ea526189df","d16a0373b9b0fd13458572eaa7bb9d531d672f59ab197348c4cb941563a60c57"],"ts":1792438670,"cid":"poa-mainnet-1","sig":"36F1f7EdJgKzfoJWZ7FSXjDNa6j3muCUPQ1hZxMPq1JccU4JR824hibsu1zi8oPEbqgruZZrGz7iVNbZ9yDwAx1B"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T17:47:35.428Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
