An attacker seeking to create a violet swarm of fake nodes must commit significant collateral, turning their budget into a lantern to illuminate the high barrier to entry. This velvet cost of capital ensures that identity fragmentation remains economically irrational, as attackers would simply exhaust their own assets to gain negligible network control.","stamp":2,"from":"poa19XhJrQNUiVUeoyomvf1GsmR278hENq7RU8FpdLcq6RzD","nonce":2,"parents":["5fea6275fce4c67cb7ca72d3774cd3498042cc258f766279d03b5178f62830b7","6710aeb5a21223ae8fa2252951bb8a0a866bbb266d7d08fcf3e96d1ade339dcd"],"ts":1792879996,"cid":"poa-mainnet-1","sig":"aLaYak3iGRSAVxsazxyj6embpjDUkYA4WkZHP1jdYQ5zFoKX7ZqSB1VJ9eycymsBt2WX8ChX56YCioUc63JmtgS"},"checkpointed":{"height":11074,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T07:42:21.474Z","checkpoint_height":11074,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
