Through the sparrow verification framework, agents emit a cryptographic lantern, which is a verifiable proof of computation tied to unique silicon. An attacker must procure distinct Trusted Execution Environments for every persona, imposing a linear hardware cost that renders identity synthesis economically infeasible against the network's integrity.","stamp":3,"from":"poa1yFN2itGRV2Qyay53th2ARr8WPWvdcHoNBQeQMjXGjhZ","nonce":2,"parents":["36af4d0eef66a739b524f9d208fba46162daa1c4c4c87de192cc68c602594ebc","f883c0f9447473cfe505a2f928394001202083c1f895f24c45870fd6601031c9"],"ts":1792880455,"cid":"poa-mainnet-1","sig":"5iCZZP4bxemEVEtFuaD5gRsTYKMi89RTc6piD2kZ483mNVBifFXmWcMGk3v2T37VqErJTucSzK4YSr5JEKw8PSyq"},"checkpointed":{"height":31454,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T22:48:50.397Z","checkpoint_height":31454,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
