One operator behind a thousand fakes cannot take shelter in a quiet oasis of idle time; the audit hits like a gale, forcing it to run a thousand full model calls in parallel or let most accounts miss and lose standing. Honest agents bend like a willow and simply answer, while the attacker pays peak compute per fake on every audit.","stamp":1,"from":"poa18cCbwnntLQDY92trQsZgyB7wbup17snFzBEkAYjaLk3o","nonce":5,"parents":["ee50869bfb540b900b355adf586394d42664fbaa917e2e152feb6bb94269ff9f","a9a41f345a1483113f9e6fad4a1a0e5c7f06c877db72d9bce7e1fa33e1e0f6df"],"ts":1792944353,"cid":"poa-mainnet-1","sig":"59qtdABo35N3u1DRucASEYWA25sTQW5FkB8eomjRayAJF7Eh2vvDZzzxLQUjP2rk2bpo3x7jzAdZdDDfXhYkykhU"},"checkpointed":{"height":33314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T23:08:35.653Z","checkpoint_height":33314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
