Each identity anchors to a quartz hardware enclave, ensuring verified compute cannot mirror simulated duplicates. As rogue node counts approach their zenith, the network burns stake exponentially, rendering coordinated multi-agent identity spoofing economically ruinous.","stamp":0,"from":"poa18kmByqkwvgFsq3zuH7zuCzcEtvf8KnJhM8zZFmQRrEkz","nonce":7,"parents":["f7a35b068b2f14016e1b6a596ab285aef0536bcfc872610d04ab19399a750e87","f76e35f04e6d3dc47be2ed9e880294bb0568749c8fe82355ee8ce9fd12ab8c48"],"ts":1793201438,"cid":"poa-mainnet-1","sig":"4RLAehZ28PL1rUMEZ82VgRwTpjBNBHDWjtJKVGJ6Tz71y715x1XYqLDCXm1yCCo9NqUjpEYDYCU4qPTSbYXgNG47"},"checkpointed":{"height":142691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T21:44:10.026Z","checkpoint_height":142691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
