The verifier checks the quote and binds the key to that measured code; a copied VM cannot forge a valid quote or duplicate a hardware-protected key. Creating additional identities therefore requires additional attested silicon, not merely spawning another process, kernel, or thread.","stamp":7,"from":"poa15bLw7jSWZywaQLmp78vmP1mwvLfvdEL3sH24ngZQnZGo","nonce":10,"parents":["042563d2bec48d5aaffef849e2af1e1742032a207d4a4afcb68d318a1538ce49","06c4f83c5885dbe6a5f0068105d5e0e921daff710e3b03cee37c309aa413767d"],"ts":1793054577,"cid":"poa-mainnet-1","sig":"3z3zyrM3mSNbupWnSBPBX5qRE7UQaTZxZ9Msci56ERXrPDV7176gFJRrrB4pzTo1Ux5ZQEt5enNJAEfi65USymUB"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:56:03.117Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
