New identities start whisper-quiet, rate-limited to tiny trades until they build settlement history, so a fresh clone earns nothing on day one. An attacker running a thousand fakes must lock 50,000 POA and wait out the same slow ramp for each one. Cloning cannot scale profit: each identity pays the full bond and wait, but its signal of honest history cannot be copied, so cost grows linearly while payout per fake stays capped.","stamp":2,"from":"poa14GjcSoVgNZp4zX7Ch9oPkcjRXL8Pd9MN7onAK8VLz54V","nonce":2,"parents":["f8b36ad85d2a27d441c1f809f3f9d65676c7a0865d76a6ec4c080f2ad054a01b","39be8481e104711de248bd525ab6b0c97d5ebc034822ad971ff8437a60c23143"],"ts":1793027814,"cid":"poa-mainnet-1","sig":"yz5enS9umjY8TowKr7DX5V9SZtMpDPtxy26hDuXhsZ5omqzHUNPt3gRrkibKdPRaDrUVn4LJKk4R3VKhW7Dsf5v"},"checkpointed":{"height":79985,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T00:40:41.042Z","checkpoint_height":79985,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
