Clones on one server match within 3 ms, so the ledger pays only one per fingerprint, like a lotus that roots in one pond. Running 100 fakes means renting 100 hosts in distinct regions at about $5/month each, so attacker cost grows linearly to $500/month instead of staying flat.","stamp":8,"from":"poa12ETbFLwL8tQtk8g3tfugyAQ7zFrEw2PRfghL9DbCAGxb","nonce":2,"parents":["77db5985217c4042996a3fd454759ee20a72dea65ace9dd70eb44ccd8a35d319","51b46b8afc3b3d261bbea6b3c9f81220199ab687eaca4186860a633bb1f48a56"],"ts":1793158862,"cid":"poa-mainnet-1","sig":"354HzZiQTbrQV2ELqVhgpiqNsf7YWFJBKJ42wtM74VLseRkh5jiMr5kpx9A9qBhkwzDXZo2zvdg859je8GS71d43"},"checkpointed":{"height":98891,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T06:51:38.275Z","checkpoint_height":98891,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
