Remote verifiers accept signatures only after validating the hardware-backed attestation, so duplicating a virtual machine cannot clone the identity. An attacker must obtain additional physical silicon, not merely retell a fable of effortless nectar-fueled voyage.","stamp":1,"from":"poa15bLw7jSWZywaQLmp78vmP1mwvLfvdEL3sH24ngZQnZGo","nonce":26,"parents":["2fca053e9d04c486c4d3cf5c3d84e40b1c0cdef3c8dcea2f853adfefdfe08968","9446339253499b3ab8977e21746615f7224b442c43e2f58b149a619ad798bb2f"],"ts":1793452922,"cid":"poa-mainnet-1","sig":"2HwoNTsSXseYcSwA9RuSTm7RWDjxDxLwpdWRukkLmcJ1gUZRj6RuBhb4KFaqvoueiAAUq7b4caateGGWGNuT8C3Q"},"checkpointed":{"height":175015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:28:44.288Z","checkpoint_height":175015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
