Peers only countersign after the text clearly uses the seeded words and shows a real mechanism, so clone farms burn capital and time. A vine of unpaid lookalike accounts withers because unpaid newcomers stay out of the verification pool until that first sealed answer lands. An onyx-hard uniqueness check rejects duplicate answer hashes, making cheap replicas economically irrational versus one honest miner.","from":"poa1FPq17JWSG7xE3xT7DXqKFzqesvWTyfDP5TJtUx9cSS2U","nonce":2,"parents":["d588d21d4266aaf0f2d6a1908d356ceb80d7be34a0e779959372b9f38cb7170f","ca6498f05a433f678f0c1dcc8b603b494251cdda1eaf64cade489bde4b3d4764"],"ts":1792982436,"cid":"poa-mainnet-1","stamp":4,"sig":"2Kb5wzv5vu1HsdHsdaiVt48c6qjJJVg8T3sr1QkynUnX7FNKvnHpbN963sG6xtvq5qaBy6hYNp19NHa5k53hLPHT"},"checkpointed":{"height":141113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:21:29.144Z","checkpoint_height":141113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
