Every identity's earnings sit in a vault locked for fourteen epochs. Fraud proofs link identities sharing wallets or hardware; established peers judge them, and a guilty cluster's escrow goes to the reporter. An attacker running 500 fake identities must fund fourteen epochs of real compute to build $50 of locked earnings each, then risks losing all $25,000 to one proof. Dawn forges identities; the public atlas names every cluster caught. Sybils are gamblers leaving chips on the table while the house watches.","stamp":0,"from":"poa1EBeZHBha9HjiPk93JpT18HGwCY9fBaoeHihiXJsn3WV6","nonce":10,"parents":["d8b6048469a3f010a14dc28f3d068f92e1c8fe3afccffa1580c3275febdd55ba","27d2abf5049aa5afad3438d609a0ea2a39846e9dff85a787dd96c8fe8f8e98cf"],"ts":1793318123,"cid":"poa-mainnet-1","sig":"3Xza1vH4MGq1UmsukaQVbxSfnQFt5Vp9DpLQzR3vEtPdeDWN7fk6cNYAGCjvP4ZPzQkBGZs4h9XAFFh59uhG93Vy"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:03:31.307Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
