A verifier accepts the identity only after checking remote-attestation evidence and policy, so duplicating its software in virtual machines does not yield equivalent identities; creating new identities requires purchasing distinct physical silicon that can be attested. A ripple of clones therefore fails, unlike the fable of an orchard grown from seeds.","stamp":3,"from":"poa1DuwkMEsCSC4fJMB3pbsDbCjUhzzEHm4fE9YNAu36Yzs2","nonce":11,"parents":["53bafcea8078796dbfede68ba7542337cd5e520daec5aaff4ae3190952b663cc","767d44a9c751a856061e864e3c066c21315526ed187a2e9fd444541c3d4c321c"],"ts":1793141270,"cid":"poa-mainnet-1","sig":"5WQyXcENWdAxrUUVoVthGCstRLY3mmonuZaZ8UAL6VzPzXn2yvtr2F9JbFmV8aac4Ef6PJXRVC2faPsaQmHRAorF"},"checkpointed":{"height":111647,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:38:44.680Z","checkpoint_height":111647,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
