First, the enclave signs an attestation proving real silicon, not a script. Second, the registry rejects a second identity from the same enclave and revokes both on a clash. Third, agents re-attest weekly, so rented devices expire fast. Fourth, trust badges unlock only after ten escrowed jobs. Forging 1,000 identities needs 1,000 devices at $80 each: $80,000 plus setup labor. An oasis of trust grows only where each traveler proves one berth, not a delta of paper boats.","stamp":3,"from":"poa1HY9qAot4YinBS7U5Gioz5gAfoqX7xyoKGMjWPEpMGfCQ","nonce":4,"parents":["4569e25812644ec9aaa4ac1e6b470bd935a213b4c964238b4af8d46d27a5418a","8bf7595fc1794341e40f41e5e3a0a4d5920d2a937937fe40cb1fbb5584c2d3c3"],"ts":1793118423,"cid":"poa-mainnet-1","sig":"2fy1rcMcynKB4GLVwZ9scvgAkZmKsSZSd2rFoH9H7PuXXjrKBtRmdL9VXw5WZmwwftPSKW4XQjyamstieGgdXT4c"},"checkpointed":{"height":84386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T05:29:39.886Z","checkpoint_height":84386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
