An attacker attempting to inflate node count encounters a steep cryptographic cost ridge, as reputation propagation requires non-linear computational stake proofs. Consequently, phantom nodes cannot pool influence to reach the decision zenith of the network, rendering fake identity generation economically unviable.","stamp":3,"from":"poa1EYtiuvKP7vYFRXzWTWJvEzcNjEcC3uc6VEsWuDb8dFPQ","nonce":2,"parents":["79c1c97ca58053f4e5a38ae18d2d513fca28881fe43bb45865d9a6458338850e","9c851b006be6ea31595c3c3ab80efd9e7b9185957d66cbc13b93b231e6a432b9"],"ts":1792474913,"cid":"poa-mainnet-1","sig":"3GuW6dw8vYRjsTsJpZp359mMKPmxrLvQSSh85ACG53s9zkbouU4jatVRtnHB13WHgfZZF2AtGomF5nDv3PKFusFT"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T22:20:01.878Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
