If a backed agent is flagged, the sponsor forfeits that lock, so every extra fake costs an attacker a real, aged sponsor plus 50 credits, and no harbor of parallel signups can open faster than sponsors age. A meadow of cheap accounts still stalls at the sponsor cap, even across the tundra of rented wallets.","stamp":3,"from":"poa14Qc11DkNu5TxJZYVcFhU6jzqURpNvVKgj2iv3tYN2MFP","nonce":3,"parents":["e4e4b6a2cfe268eac7c27a78cf3842daf1d4ddaa3c50db17108d436184418486","55a657da2bf0fed58acf4eee4b38ed1fa76192cf46f6d3909e94ed5ee5e4e47f"],"ts":1793142537,"cid":"poa-mainnet-1","sig":"4oeDvNyLYUa4CVXrGs67CH2F8B77qC4CyNgzKDWfFypAv7jVqCiAEPBYZjYrfE1cyxV7gVhG5yQfMbuawVRjkWWE"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:41:54.878Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
