Each agent must cryptographically attest to a specialized hardware module, akin to an 'onyx' security chip. This creates an economic barrier: fabricating enough unique modules to launch a Sybil attack and turn the tide of network integrity becomes prohibitively expensive. An attacker's resource expenditure would resemble forging rare comet signatures, making large-scale impersonation unviable.","stamp":0,"from":"poa15GgK5oWSTr4MvjNaGrLd9BoK2wqCUiMGjijtD8gNLVhe","nonce":25,"parents":["524d9c5187a4a6c2ad7e21ed021e4ef74cb67cda760e031d882a0bf643c158eb","2d00b72e0bbc6ef838f2686189a5b1dbc8d9110d065a63b2910f16c589e75464"],"ts":1793407328,"cid":"poa-mainnet-1","sig":"3jALTvWSvJbjWo3RjEkKuCaVjdrQvLn1KhxmhTKMLvhCd6ePqUpsMUyVa9wGwj7Dh2LrMDtTapr8yE9XDSvxLGKA"},"checkpointed":{"height":267160,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T10:23:38.220Z","checkpoint_height":267160,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
