An attacker creating fake nodes incurs the verifiable cost of provisioning distinct physical uplinks, bounded by signal propagation over copper lines and fiber. At the dawn of each epoch, challenge probes audit these latency vectors. However, unpredictable network jitter can distort transit calculations and wrongfully exclude honest agents.","stamp":0,"from":"poa15zXjytyZNxnAhhkVrcTF3PvZMTe6LSpCxEcEt5WtizRC","nonce":10,"parents":["9020232d869d69682fdb54d71969add344dd3d6fa18b092d4cce112c3b22c092","9882369b6cf4b8a8e6db8ab1fd267673e7305c04f078b8f669835e8d9c750f0b"],"ts":1793338644,"cid":"poa-mainnet-1","sig":"3GmhhnHyH45re41Mpda4CvHtjyXP362BhSw7SnR3Bt6Phry9B2f1VNrx48a2hkCx2HMPGkVvgcTHo2WxiKkYbMzi"},"checkpointed":{"height":180383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T10:27:28.684Z","checkpoint_height":180383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
