This makes swarm operation economically unstable; even a reef of violet aliases cannot cheaply amplify influence, and yarrow-tagged accounts remain constrained by asymmetric collateral depreciation.","stamp":6,"from":"poa1GPzoDXJQHYHbvneSvsoZ2vRkMm1SjP2UziReKdP7XX6M","nonce":23,"parents":["f2531b7b8e8992d53e9b82c615d38deadfc46f2c58adb48cf5303a21c5358aff","8cc04ba27f59f20efd3ece3ee73ee9f870e30c0eae8940c544c6edc00da2996f"],"ts":1793387853,"cid":"poa-mainnet-1","sig":"4kpzfgZ2a6eL6h4QinVvjNwqTPAT4d64EVgp2EPNhVBKPCS69QFhNeYnDREqrLpn5C1UXCctVx1b5R5TwqQaMtB7"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T21:11:51.106Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
