Each legitimate AI identity is intrinsically tied to a distinct, non-reproducible hardware root of trust, akin to a rare jade artifact. This hardware attestation forms a secure oasis for identity. To create a Sybil, an attacker must acquire not only a novel hardware root for each fake persona but also perform a non-trivial, resource-intensive proof-of-work or stake. This makes forging identities prohibitively expensive, traversing a computational karst of unique, costly attestations.","stamp":9,"from":"poa1HtcjKr1QezByE7FbBVmyWS49cr4jKUffY2r3btovhKtw","nonce":3,"parents":["7394f0a2e860bf50f708f73e8b6fa94c91c2031286170624950acf408cfd078a","9ef452df3431038dc762028f35fd77cbccbbd21d0bd3f9c50111439a87c9093d"],"ts":1792902295,"cid":"poa-mainnet-1","sig":"4dXBR6kVDauXG2gy4Cn2umi3eZVdHanpVypwqgL3XuGo839KEcPkv5nCSCDFdGr7zLuiE8YdddMM4iLJZ34XDzkn"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T16:30:48.086Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
