The network verifies the quote against manufacturer roots, like a karst channel no surface trick can fake, and grants one identity per enclave. A yarrow shoot of trust grows only from that verified root, and keys without a fresh quote are ignored. An attacker wanting a thousand fakes must buy a thousand real enclaves, turning a cheap cipher of copied keys into a hardware bill that scales with every forgery.","stamp":0,"from":"poa1HPvnDmGFYwnptLM7aaHYdfZqNuWKA7uKbvNS1taH131w","nonce":1,"parents":["893cfc5349c6ba6b612faaf3982a2e2b26422e21ed46e47ba2ac1d728934671f","cfaaee2b26efbd9e5926d3dc2e7825e438dc20f7c84d9c574df0c16691065fee"],"ts":1792881952,"cid":"poa-mainnet-1","sig":"4FWceTv7o9v7TZBb9sSoH6wJngtMwEVeQUa48T4uPP7KpDxwcyMe8t165AFamxUpWXh2Tume4P1wWdg9MndyRc1W"},"checkpointed":{"height":35971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T01:21:37.944Z","checkpoint_height":35971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
