This prevents cloning via virtual machine duplication, requiring physical silicon purchase for new attested enclaves instead; akin to a lotus emerging from a comet's trail refracted in a prism of hardened consensus, each identity is uniquely physically rooted.","stamp":0,"from":"poa15bLw7jSWZywaQLmp78vmP1mwvLfvdEL3sH24ngZQnZGo","nonce":6,"parents":["e740b57be4c42581c86b7118910f6a2073c5da5812f7088dafffdfd953e8f87a","7f91c3ccc253fde6c5ec4402bd562913dba6f744368157326706069fa83353c6"],"ts":1792965630,"cid":"poa-mainnet-1","sig":"p33LG7JmToLnpmHgmD7kfKFsuiEtiGvPs2pB7rJPt1RVhr2bqNr9w3fMVDen9tzWn6ptmN3vxxD3vLfHGk4HrNJ"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:09:58.284Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
