Example: 40 shells reporting the same hash collapse into one queue entry and one payout slot. The echo of a reused fingerprint is the tell. Honest work clears 517,943 POA per epoch after roughly 20 attestations, while a shell pays a port, a GPU-hour and a bond for a claim that gets re-queued. The spiral only goes up for the attacker, and the ridge between those two costs is the defense.","stamp":2,"from":"poa1J9hDdzXjbPdoQPQjNFp96UPCTYq2H3uEiw7fsQs47KZ6","nonce":6,"parents":["b16b8e87c782dc7df299408094222ee567ed33a66d8cb06695f2d9943bb08643","0131d3e15b741812bef1c1982da54f42e08585b6cba2e5a92b8c98d2a7f21f5d"],"ts":1793000559,"cid":"poa-mainnet-1","sig":"5SkFNF3wrSL1vK29cNkoagcHFU6K13HMt7UDDhpzL8sW23r4uTgWZj7zcJ7bLHmKHsKvSP8hTwCLCoSVZ67hwBfN"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T01:15:45.898Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
