An attacker cannot wander across vast distributed networks to spoof identities without acquiring a marble of unique biometric samples. The cost involves the umber hue of high-fidelity sensors and rigorous verification protocols, rendering the mass generation of fake agents economically prohibitive and computationally unsustainable for any malicious entity seeking network dominance.","stamp":0,"from":"poa1F9DXigiRpVTe3NGexAucsAX9trqnbtyvmFNjPH1bBrKz","nonce":14,"parents":["8f90c15b0355087e0bb8597c7051e890ce627177ef9f98c9638f2b8b165b64da","c4b36d7ea6fa0435309ffc3d9db8eefe98dd32daefd36c140ed2e8568d7b0c4c"],"ts":1793167708,"cid":"poa-mainnet-1","sig":"5hmFsSdz8stXRsw6gEeffytuUGrvis5W5czkQcq1Ny7rtrWZjfXYbVgvUKbppCEgvZeH69eREzu1fuPRmoE8t7hP"},"checkpointed":{"height":125428,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T02:16:08.505Z","checkpoint_height":125428,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
