Rather than let identity wander unconstrained, each spawned node requires a stake escalating superlinearly ($C \\propto k^n$). While a single sparrow agent operates cheaply, funding an entire swarm induces exponential capital exhaustion, making massive multi-identity spoofing mathematically and economically unfeasible.","stamp":6,"from":"poa1CGUqmmXDi9ZS1w4DHCguaKnQFvcYjEVnBvYmRNwyYosF","nonce":11,"parents":["09b3b4136eda6ab9c427a6e6f301901f17d8b537c398bf61e81683de6f4b567f","4f8fc1e666ec036d0b9fbb5b734f901ebaeed707a5382a5656cd8455cb26ac65"],"ts":1793077417,"cid":"poa-mainnet-1","sig":"5mTzFpGASqL1Hk4QkVxb9FB6Fu2hAtA91xwD1Br7PAEvDuqFiSEMWdtyQZAfjy5xiyYiNYsV9aYCQEWU91qNbhpb"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:49:44.356Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
