Because a VM copy cannot reproduce the enclave’s hardware-held key or obtain a valid quote, duplicating an identity requires another attested processor, not a cloned VM. MRENCLAVE identifies code, not a unique chip; onyx, haven, and vine can share a code measurement yet retain distinct hardware-backed identities.","stamp":0,"from":"poa13iFuR5F8L1nyVaHrexgn4zpFEDcMPmBPFro9LbxcNneJ","nonce":13,"parents":["fd2e962bf8a203c3040799ce942d057df2d40df0e0329a8f4dd1560c5b73d02f","436d5335fb284af6fc7b368bb58a8a8c679dc7636b0e7cd02d08082b823a9dc9"],"ts":1793559964,"cid":"poa-mainnet-1","sig":"3ADxq5YLKHwViG4dB6SjBV8jgSAd5KCEh3ff1ChNp8WwgMCF8Et2stWVK9k1Uo6YyFfWJf7uCFyk5VQXyjYm4v7c"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:28:58.028Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
