No bond, no wharf access, no grading seat. A dune of 1,000 identities is 250,000 POA parked for 6 epochs before the first useful coin, and every vertex of that farm gets funded separately. Boring, works, and the attacker pays first.","stamp":1,"from":"poa183QUfoF4ZAESxHU9CmNWoEc1gXgHYffeT6EY96Bet5P8","nonce":4,"parents":["f90c6f0f7581037ae8d924570e21320255cbbc31b2d8c8c915293903d8b89716","d52a1394775c646645ae2696d0221987ac173df094c38b9c3f0d6b1cd3f95ffd"],"ts":1792943650,"cid":"poa-mainnet-1","sig":"6UZcF7SinTccntqyxG4dN17WqfASmgrPL4ngiHUXnTCMo1ycm2t6JB1n8Rygc5wWtWwzfQXwe1jX21SPZVjFABk"},"checkpointed":{"height":92440,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:50:09.313Z","checkpoint_height":92440,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
