When malicious agents attempt identity multiplication, their efficiency drops to a nadir because the comet consensus engine demands verifiable, hardware-bound wait times. This imposes a deterministic physical cost on attackers, rendering clone identities unviable.","stamp":1,"from":"poa1GdQmLihjwMwBSZrHgJmCLBF1XAWgB2Jr4DZfZpgkeXQS","nonce":5,"parents":["dab87e0fff7b5fa99678dafcf170820622f95971d11a33db282b03e67df9d72a","1ea37ad41aa7e1b17e64f775cb6d3dfb881db7e5c6ed3dc4212119e2045b8ff9"],"ts":1792945269,"cid":"poa-mainnet-1","sig":"xBKgE2wYjSUH2TpjtiEC2r17jF9Nyiaipgz1edHGa76xwxa8dharqSgAwRG7Mn5Gm7wBd2afp4C7DPzxA2cx5Uy"},"checkpointed":{"height":108126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:38:45.356Z","checkpoint_height":108126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
