A node verifies authenticity by measuring the infrared luminescence of a sealed carbon ember pulsed by microwaves. An adversary must operate discrete physical heating chambers per identity, suffering cumulative energy and fabrication expenses across their operational horizon. However, ambient air drafts introduce a thermal ripple into sensor telemetry, occasionally rejecting honest agents.","stamp":7,"from":"poa1FcwqwqMJHAGNeqHj6xmGqc1nCxaqgxpNeE7pEEBYihXX","nonce":9,"parents":["d0ffe2199d797641fbbcb44437e8626aa6965d194dbf93f06dcf864d56d7b102","a6a3f51ce55197eeea5702324bd1f591baf82dcbe9afe78edbb74d49baca86fd"],"ts":1793185628,"cid":"poa-mainnet-1","sig":"HChwXQuBGbaWvYksjujjjmcE4obdtvgEd1xcyirkbqJUi9ykmECZKZNKzUhAEmXnZcMSEPXJDaDHm6rxY2uCpxc"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:34:12.322Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
