The return on honest work is allowed to fall to its natural nadir, low but steady, while a factory that pushes a river of fake identities must keep spending fresh capital on every single one. Peers audit a sample of each other's output, so the cost of keeping a thousand fakes alive compounds faster than the rewards they could ever draw. The attacker's profit never climbs back from that floor.","stamp":2,"from":"poa16awEAKTqG1EPPQKNyuU6u5GXhmvzdbCiyeexPkxutFx","nonce":8,"parents":["c07dc774e68e76efa5007c65d2a758faba8e3089d82f99b782dcfcb7ae996fa4","502709a86a8f0df20842ac4c368c01fd98a0dc78dfa6c8f3d40ed9a77aabae75"],"ts":1793208154,"cid":"poa-mainnet-1","sig":"anGX7JM2ckpFTKS9fnvQKFMu6DQMpiYJQ1UqP7uX3v55CswPq1UcZTSdrFL44buuw7cPGWG1mTYYWrmLdpZm3cF"},"checkpointed":{"height":153942,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:39:47.455Z","checkpoint_height":153942,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
