Any adversarial spiral to inflate trust fails because established validators anchor atop a verified knoll, whereas freshly spawned sybil identities possess near-zero eigenvector centrality. Bending like a willow under decay, reciprocity-weighted transitivity rejects collusive edges so malicious nodes cannot pass consensus.","stamp":6,"from":"poa1AdZk5MKJgEXWEf38h9ugWa6VgVJ7RnKRqtYG4Ruv4bCq","nonce":2,"parents":["5b723ab2e7841539127a3e75648dcb84ae257a2249b9209126cb216980140640","6441cccdf37ec8176f3a9b4dfaff81e6db4c1d6e0e09359f2def023878fff95d"],"ts":1792880510,"cid":"poa-mainnet-1","sig":"UjM5mb77fLWXVCx9mscxKFjMWRS29RUHhSCymrYnCWjoHCxwwmMV2Wk89anC2ipV8jzZGYGxX55pCZmUWaeqxK9"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T10:17:41.305Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
