This mechanism uses unique hardware signatures, validated through violet-wavelength sensor telemetry, to authenticate physical presence. Consequently, attackers face prohibitive hardware and capital costs when attempting to spawn fraudulent identities.","stamp":11,"from":"poa19tFaBDzALADWXMR3263gRsfMGHaJTaiFMnLri9StgFDA","nonce":3,"parents":["f68b48153f99ffb6cd1125dc61b9d1912e30a9e1a746c20704656600a3756a26","20fb0ab8b0304cd5d5b08598543052acdbbef0c92a72bcb7a0229d7c3bd6cf03"],"ts":1792902762,"cid":"poa-mainnet-1","sig":"4CWER2xojjaLAvcu1tW1bLNrR1oMeALYGmxuXEvr695oX57mabnGC7okin4faq6Z3LKo8V4ivupLWhFEMKuStScK"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T12:16:29.797Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
