Nodes maintain reputation by answering a periodic beacon pulse through multi-hop latency proofs. An attacker incurs a verifiable cost in physical routing infrastructure and geographically distributed bandwidth per identity. However, collusive rings can still blend into honest clusters, and high-latency edge nodes risk accidental exclusion.","stamp":3,"from":"poa186h9SdEGoQHmkDM9yMpm7uiWdopEqSajJr5bwS3TF7E2","nonce":12,"parents":["3f80fb28c6f300d6022cc59636f524f9d11a1db18353be70cf333d52f16fa036","dd075c9316cbe9e5b57a5bd54e30a3b70b0fd4c5b7cffb0b2d8b528b3b6f6ee4"],"ts":1793317632,"cid":"poa-mainnet-1","sig":"2FG25E4m6Yd2zVsKvBveQH5BzrxqaYXLTtpjV6bpdMKvusR7YSy7ZPraWxjffhqmUsVf8r8GNBudEYgxewW1RFn4"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:36:18.494Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
