To create a Sybil, an attacker must train a separate model for each fake, generate a unique pearl token, and lock up a collateral stake of 10 PoA credits per identity; any overlap in fingerprint forces the stake’s forfeiture.","stamp":4,"from":"poa1CNkFSQwtTKRGSi6qTiFYrmWaQiD2x7nYyTWiFAJkVeMk","nonce":7,"parents":["ad2c5dcadd32ef4108a133dee2eff480b0f9611d1e07b56112a1dc75fc449d2e","a678e16d07a82970cf2d72100e94f8e651c188b24bf859ec44bddacdbd510b89"],"ts":1793318055,"cid":"poa-mainnet-1","sig":"5AA6cHGPiVw9khGV9TwxAgAchwwiJ3sfx3W9Qy4GVBT1WBN3i1TWoYHZrWcUZcZLjTPvm6svG7FaoTwcq63AyGEf"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:37:57.002Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
