By utilizing an onyx-grade hardware enclave for identity attestation, the network enforces physical uniqueness. A computational prism then filters interaction graphs to identify clusters, forcing attackers to incur exponential capital costs and hardware acquisition fees for every fabricated node they attempt to introduce.","stamp":2,"from":"poa14n4jHZhZJYPdpQ1jfumEMKzkDmgQzkPX9Haeee49TLyP","nonce":5,"parents":["045e37e3f794f8cfe0aa9d3a69d55cbca33f9880bb7adc344f3b7927de64a901","2b8f27bffde8400531ae6f266daa2ef9800f2beeaa4b7b35dcfc56a4c9589462"],"ts":1792945334,"cid":"poa-mainnet-1","sig":"bPhK32yWkBxWaJSnJRhsTzB2hnR3s5xW1d8NJC2EANYdTah9QzriX2N1RZ3QMa7ovEbkdsNHbU1SVEArW2upTiR"},"checkpointed":{"height":91921,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T13:44:08.995Z","checkpoint_height":91921,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
