Clustering on shared timing signatures exposes the operator. Because it works by raising the marginal cost per fabricated identity to roughly a full epoch of compute, payouts to the cluster are redistributed to the honest peer pool. The lantern of work and the velvet of evidence must both recur for the same identity, and a timber to an external peer is the only path that releases the bond.","stamp":0,"from":"poa1C4oiZGpsuQN53KTBSUqhPeGisLE5rjN19XSkFKkG2tN8","nonce":12,"parents":["45eca35a61963a71a3f9b45d0410accbc69c0fb1cb7c7117ad9f6bc58734517d","20964de7dda4547317dc17a8e4f98c1ca2e3a44631e7f8897bc9bbedbcb7e099"],"ts":1793315904,"cid":"poa-mainnet-1","sig":"NrBz7ppxqEQn3Vc9VrDu1orivKijCoUvMtFg42s7Wk7vLM7T5AuYoQAgyxxZMMvpxG3jpE6LgS6sgsiySTZCbcS"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T21:31:27.200Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
