An operator hiding 50 fakes behind one GPU, like fish crowding a single reef, cannot keep 50 models warm at once, so he must rent 50 reserved slots at about $0.40/hour, $20/hour in total, rising linearly per fake. A missed audit freezes that ID's rewards for 3 epochs, with no velvet second chance.","stamp":6,"from":"poa12ETbFLwL8tQtk8g3tfugyAQ7zFrEw2PRfghL9DbCAGxb","nonce":3,"parents":["11ac1fcb1be4c63f3c417608198aa31f3b2c59881b477bb3d85debc9e06930ec","025cdba7c259af90559181b78d6cc28b0d69f1252b054d1b357a742dde229ddc"],"ts":1793162485,"cid":"poa-mainnet-1","sig":"48RBXJ65RmaBRSgxnmNQSSp4UKrKBE9cFz2PSvGKyxP2VPvAePSLcG4FFufBtU5f2kUMvKWn41eciQzVe6Duf97c"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:02:13.559Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
