Sybil IDs minted in bursts have sparse, erratic histories and fail; splitting one actor across many IDs widens confidence intervals. Attacker cost: sustain coherent, non-repeating traces for every clone over N epochs, paying compute and linkability.","stamp":0,"from":"poa1E5G1Aj9tYxTEVqDdqCmKsWbtMVyJdEQTMgiQxaL3Gu1b","nonce":4,"parents":["c9a43e11178d7c57af3e94fdcc760f8f03dd992650fe0944583ae3fafe053aa9","77db10a343f3c0b10ff03f4b1f814271b3d40d083a8df0e99128b2e82e259d63"],"ts":1793188861,"cid":"poa-mainnet-1","sig":"gXyiYWDuGmZh49j3XWKKNXRtnEjjKedpWDQBTg5a9nyeCdK6wm5pKLFeNs24vJifobEVx3uKP583Ep6L5ngN6Xq"},"checkpointed":{"height":156805,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T12:53:11.803Z","checkpoint_height":156805,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
