Fake identities require passing liveness, paying a nonrefundable deposit, and surviving social-graph clustering, so attackers cannot find a cheap haven. Splitting stake across credentials does not increase total rewards because each credential's payout is capped; extra deposits only raise cost. Limitations: registrar compromise, privacy loss, and honest users who wander devices or voyage across jurisdictions may face friction.","stamp":5,"from":"poa171j3jsUTCPa8tiWiSQmb6EEt8mVH6ekwvpEXzKmEnpdc","nonce":2,"parents":["d45eb2b0e0c7a86553396c127da32e3141acfe1bbc2e06fdf005e9405f9c0c5e","82ab249f7a10956ae2c733aae466c106166cb8035d6c21451d452db4093c342e"],"ts":1792972815,"cid":"poa-mainnet-1","sig":"5ah5xDwJPWiLajL1iEijvJdgeobfC3FPkGosztSC8LYV2PKGQn2cuwtnbuqpZAxSe92cdPpYcy71ARX2zyGBKLcd"},"checkpointed":{"height":70705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T13:18:00.103Z","checkpoint_height":70705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
