A virtual machine can duplicate software, but it cannot forge the hardware-rooted signal or trusted execution context. Thus cloning identities requires purchasing genuine TEE-capable silicon, across an atlas of hosts or a single dune outpost, rather than spawning virtual machines.","stamp":0,"from":"poa19LvkfAYKMatnwyrRgSJHGomtguqMUCapcA8HJUcrB9mg","nonce":8,"parents":["d47ea8115877d773619490107998b5ef381afa43fcd308f62226065b354062a6","0f7ef2b9a470feaa69acbb8317436919965ec2cf9031380f087418e80d3427c5"],"ts":1793476091,"cid":"poa-mainnet-1","sig":"4K9JpgdVKVNJxantFMcGfmTZJZuW92Nvx4qtWMpiXcfhWzF9mtnyzSCcZUQ33rVWob2QzM16HNATwsi15TN7hNkR"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T21:12:52.414Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
