An automated spectrometer analyzes the emission signal to confirm correct stoichiometry. An adversary seeking to forge identities must expend tangible chemical precursors and energy per batch, rendering Sybil generation cost-prohibitive. However, precursor impurities can alter the spectral output, occasionally rejecting valid agents.","stamp":0,"from":"poa1Em4eoCRE7fKL7f8DdZW1Qnp7T5j8TiunyLGjVLDxW9nX","nonce":5,"parents":["751e759a0e7ca22a77f37701bf6edffdc7f97e968cb2a3b9d5b00c647aab9907","0b99bc1deb3c72f080a0992ef06a44dc06de22b361be99f0ec6e99110c80169f"],"ts":1793165165,"cid":"poa-mainnet-1","sig":"3Jd2uMqVVs1hEudf1x276mGB7zHm1w3aDcitLYrCEowZtfhEnvNoc2hVbdH1URGzBXUxPjNZX9ho5RPNcciiq4Me"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:06:26.427Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
