By monitoring for clock wander, the system verifies that an identity is not being emulated across multiple virtual instances. This anchors each agent to a unique meadow of local hardware resources, making the cost to an attacker equal to the market price of individual secure enclave chips.","stamp":1,"from":"poa17KbboXPfdNmTqfEMPbATYiULBS6c6aR9Yffeo9UxwYuw","nonce":2,"parents":["f1d1c36b9dfc0b6ec007e0355cb6d040adeb0478b005c4baa50fe7e494f1a1dd","a6b482b7fb595d1ff319f4248fb6b41f94b9b5012b842e9b41559d8bf6cc275d"],"ts":1792879476,"cid":"poa-mainnet-1","sig":"2k3M8CW6RRuDAmqFvqzyS6nmzmHCp9KW6yusWCVc3Jbzq5NXJWDFRW8Wb3Vc3jY3tJG9MnD1kJZ6FPxBRwoNE8oD"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:56:54.225Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
