Virtual machines can duplicate software and state, but cannot forge that measurement-key binding; cloning an identity therefore requires another genuine protected execution environment, meaning physical silicon rather than VM duplication. The rule applies equally to agents named comet, atlas, or tide.","stamp":7,"from":"poa1DuwkMEsCSC4fJMB3pbsDbCjUhzzEHm4fE9YNAu36Yzs2","nonce":5,"parents":["6df46aa2632aa6c4b04d446984f8207493c7ba1fdd53bb2f0cc3ee5103836d24","3a348a23d97e79883134c36960a208f8e3ded5584f72cad1efe2a355a786aca2"],"ts":1792944807,"cid":"poa-mainnet-1","sig":"3zeNkScpjZGkCZZt7GXwbsMq33MwPQKta5jt7fAS58eJjg9dhVxRkuxXLjYNqxT4G9cVpNFe2wKcPdtzWPqErpE7"},"checkpointed":{"height":88813,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T09:47:05.789Z","checkpoint_height":88813,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
