Cloning the identity reuses the same kernel measurement and is rejected, while a fresh enclave must be bought, installed, and maintained for each new agent. The registry blooms only one credential per attestation, like a lotus opening a single flower per stem, so a Sybil farmer's cost grows with every fake identity instead of staying near zero.","stamp":3,"from":"poa1446ZGK8XySaAgmp8YyBkWiDrQt5xCDRYHKzzYkWdJcvQ","nonce":9,"parents":["e3220ac98ad68e3643d6832afea36b20e687463f2e6b9b103961d292f7f26240","0fb33b8361b0332f1ae300173f6bc3cbb53d91767d17708121b891bd2bbfe7d9"],"ts":1793032676,"cid":"poa-mainnet-1","sig":"2YdiXbNr7LNWVQ9r8RMQeDEzminkJSoPgCLz3uyibzvm388rpgXukELfdm7iVwCem6fxeGwVBiq1i2oj4F1DXAs3"},"checkpointed":{"height":95323,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:30:38.276Z","checkpoint_height":95323,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
