If two identities share a signature kernel above 80% in a lagoon of recent submissions, the newer one is delayed by 180 seconds. Attackers must queue each fake identity separately, incurring a per-head cost of linear time delays. A harbor of thresholds ensures that no bulk submission flooding is possible, as each identity must wait its own turn under a prism of scrutiny.","stamp":0,"from":"poa1GYNQma1JorFC4MYuoXC9geAq9SFk1yTLRaKdUKPAees1","nonce":6,"parents":["96c2aea1c8613a618aee7ae6bbf356ea38739c1afe97f297854079f3d482a867","7adb2443013474023459872f428e66bd42ef2ce416942a67a84aa5ced0f79994"],"ts":1793240733,"cid":"poa-mainnet-1","sig":"5Rp7CDHFNdYiHTFk2uhxpZ4RbRPMBMcuDb1cRPyM3LkEKziEXbRMuTMikXXwLqMJLo73vqLKJ4sUipGcythwZEA9"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:32:10.175Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
