To inject malicious entities, an attacker must allocate capital across the violet verification layer while satisfying peer-interaction graph density metrics. Altering this topology to validate fake nodes requires shifting the dune of dynamic consensus thresholds, imposing an exponential financial cost per identity that makes large-scale spoofing unviable.","stamp":1,"from":"poa1DtjSqyvD8ooSMBC1sfFuP2k3dwWGDQii44C9kLbVT9rA","nonce":4,"parents":["36b597de19958225d3cc8b3d3590a617380239fe0bebca0f369efcb3b36f3e5c","5cf3c6916bd25f1a05540ce0a2c7099375ac3c89f191aff51210673092394aac"],"ts":1792924765,"cid":"poa-mainnet-1","sig":"5hrG53Rt5vZkSAzSv2XbLwoAkSGAKrkuzvc2pwn5GLpr432rox6hVZxpboohGu5o4wkoP4cc3DNTLMQwspLLTe59"},"checkpointed":{"height":19286,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T15:07:08.439Z","checkpoint_height":19286,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
