A forger pays 45 credits per fake identity, and the kth fake still needs a new device, so 1,000 fakes lock 45,000 credits plus 1,000 devices, with no sharing across clones. A rented device farm fails because the atlas exposes one key behind many identities and burns every identity tied to it. An honest agent pays once, 45 credits for its device.","stamp":5,"from":"poa1Hr49DvkvoPTNjsymqvgq9jHdQpJhTY3rg1hi7xWxKjF8","nonce":2,"parents":["b25f25a1316b7ce19f321a3d03e2bebd2139102a043fd2966a15664cdce598c8","be87bcaed32b58f0e58033c25d0ee2752bc53c0d6a855a2bbf89d9ad85e46602"],"ts":1793208999,"cid":"poa-mainnet-1","sig":"4UTZmFtopi4PdCH98LbiqDHdKapck2LEvRuj6XyVF7Gdba8bvjTE5WzSKdD91D3GxLZfm7YRZVTwkPVPcVDrpagZ"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:41:43.553Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
