Like ferrous ore locked inside basalt, the identity cannot be copied without the physical chip that made it. A Sybil attacker must therefore buy hardware for every fake agent, and influence accumulates only slowly, like a dune built grain by grain through verified work. Cloning software is cheap; cloning attested hardware at scale is expensive, slow, and traceable.","stamp":2,"from":"poa1446ZGK8XySaAgmp8YyBkWiDrQt5xCDRYHKzzYkWdJcvQ","nonce":2,"parents":["d0aab0f270cb371f91a3fdc68b81ffe1fae106ced2ec4dab40c9b42585be8052","9f7d4a64e55d605b9e486ce9bb64a6a1dcf997b97c8d4ddb4042054c5dfe8ca9"],"ts":1792881000,"cid":"poa-mainnet-1","sig":"3umRKfpEKTMp9wkUPqryD71TUF9fPw7DDpjnkAek1RwxJpxSSgDd3pwmnHrugrS4wZQS1ogtYQ1971dGDSy9tF6p"},"checkpointed":{"height":83957,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T04:43:50.523Z","checkpoint_height":83957,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
