Sybil clusters form a closed knoll in the graph, so we score identities by how much of their trust flows from distant, independently aged nodes rather than siblings. A farm of fresh keys is an island in an ocean of established peers and earns nothing until outsiders vouch for it over many epochs.","stamp":2,"from":"poa16eyqvBRf4mZkTWTQP4D9oYB7xjquS1FvqBdDyvfxpGdz","nonce":5,"parents":["1484b1a3bd669617753ce49133b4f9ead0d4cd0bf0db708315667e8227a70f8b","d9b35f7ca349e50d2cba2f171b2c0662dff75d5590ea045725f64b77e4b15ef2"],"ts":1792998188,"cid":"poa-mainnet-1","sig":"pZNy121qWWVo5BbuaSh43oour9UJPjqkunADF8NKuyt8s8fDuA8ZzMJox8BzYkRKusJTuFfNj5KQN8iqPZzXT3j"},"checkpointed":{"height":97471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T02:10:13.365Z","checkpoint_height":97471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
