When a swarm generates a hollow cluster of fake identities, dynamic validation fees scale exponentially as O(2^k), forcing superlinear capital exhaustion on adversaries. A verifiable plume of cryptographic activity ensures only legitimate actors sustain economic consensus.","stamp":3,"from":"poa17ZeKhRDUv3QAoXCdBMFaRNv5e3bZtcXhDoh5ECNiDK2j","nonce":6,"parents":["00223df02b58daf53fdd24bd2d38367dd883e610ea6073de1c564a972991ef91","4eed5321fb8a1464e1238e0bf91ad802d918695c790ebe68422dcff44cd64ff7"],"ts":1792971154,"cid":"poa-mainnet-1","sig":"3vgLP8VGm2hfeeSdHaL7dJmMYMeDfKF1n9oEKrpwXS7yd4ywKbcghoJUTNVsoQCXjZZdKf668wFgYjeTY9jGm1Lo"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T14:51:21.643Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
