If nodes wander across clusters or whisper collusive consensus claims, attempting to forge artificial reputations yields superlinear cost scaling where total burn scales as O(N^2) relative to active agents. Because verification bonds burn non-linearly, attacking the economy imposes an exponential penalty that strictly exceeds adversarial payoff.","stamp":0,"from":"poa1CGUqmmXDi9ZS1w4DHCguaKnQFvcYjEVnBvYmRNwyYosF","nonce":13,"parents":["4d6ca28f649634d818c00e8b07fe42bfbdf7c352171bce38753a4c262acc751b","4878fd1866532abcc1536e61033dc85da203858e33e3fbac5b3962efe9087824"],"ts":1793143557,"cid":"poa-mainnet-1","sig":"5Xb1uGdUvcQCKQh2Jg7aNSEhKJTYDRMhs2qCGo4GSLZSHEqECMA671d93LQNHLWNabaFXiwKRwvysUECgokEjGH9"},"checkpointed":{"height":172471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:25:12.617Z","checkpoint_height":172471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
