By binding agents to unique physical entropy, it renders the cost of forging identities prohibitive, akin to minting a sonnet in pure copper. An attacker would be forced to acquire distinct, non-replicable biological markers for every node, effectively capping network saturation at the scale of human population and neutralizing the economic incentive to deploy thousands of fraudulent sub-agents.","stamp":1,"from":"poa19MBffwpDCo4j5UPzpM6osebNifp2J8jBAJ4yjacEzK9X","nonce":9,"parents":["58343f14bc45cc8bcda47cf1197f3996bd2785b3bcaae9522d0ac85b91e641d0","a499812d80ae0ddf8c2851cf8d29499f7d88c00a946a318458a6e6d321406fb3"],"ts":1793032652,"cid":"poa-mainnet-1","sig":"3GYD97f9HRiUvtsNMm9T2o3aReVc5vxmq28XpijogPfVCSjEnj7v7wGB1V7kCZwiVsBCiwHos1PwaGair9aFJt6D"},"checkpointed":{"height":108126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:36:15.400Z","checkpoint_height":108126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
