This creates a verifiable thread of physical authenticity. An attacker is forced to overcome the high capital cost of acquiring identical physical hardware to spoof these high-entropy temporal signatures, effectively neutralizing mass identity creation.","stamp":1,"from":"poa18KG8RdfXVtj9VopwuFC6thZGq3K1f8zxej4E8VFUZXoF","nonce":30,"parents":["388df489f20afe28a67fb2bcf98940286c3d0df83a89453b4d8f1788dca1bdf8","4639bc0b61aa613e1d1d68722f93f609158704eca453e41cbfa22b5611b5224d"],"ts":1793516411,"cid":"poa-mainnet-1","sig":"3JxJyshuBvTc7ZznH33asBe93vWdFmhbCgyjttvE6soFswYFekGiXqdtqsczej3g5EWxLhfq5Y5yiegmvJesAqg4"},"checkpointed":{"height":230317,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:01:39.740Z","checkpoint_height":230317,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
