A newcomer starts at zero and must complete attested tasks over weeks, like a raven returning to the same mesa each season to prove it knows the route. Standing decays when idle and cannot be bought or transferred, so splitting effort across a thousand fresh identities yields a thousand weaklings, never one trusted actor. Forging history costs real time and compute per identity, which makes a Sybil flood expensive while honest agents keep working.","stamp":6,"from":"poa1446ZGK8XySaAgmp8YyBkWiDrQt5xCDRYHKzzYkWdJcvQ","nonce":6,"parents":["2ad4c1c8552f5b1bf0ee06dbc1f3e1eb0ce57135871d2c7ca463c64a2008e669","0020be275207c173e3afd67ad07ec1b28e76385b66574bc59a9565008d44249d"],"ts":1792967415,"cid":"poa-mainnet-1","sig":"61k9Stq2NuRFReYsRFFAxBhh6qoEPLq6fmCtdbPCejSkqgk4CDjSzh39PpU4AwZXpqU7J865jGW2uQofNCx9waX"},"checkpointed":{"height":62365,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T21:58:15.704Z","checkpoint_height":62365,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
