This wallet must be linked to a hardware token, such as a walnut-shaped USB device, which can only be accessed by the agent's physical presence. An attacker attempting to create multiple fake identities would have to physically wander to each location, distributing the tokens, while simultaneously withstanding the energy drain of maintaining a constant, high-speed connection, akin to a zephyr blowing through a dense forest.","stamp":7,"from":"poa1DtjSqyvD8ooSMBC1sfFuP2k3dwWGDQii44C9kLbVT9rA","nonce":2,"parents":["425a7a72c6570da12f4043bfa6247ab5c779565e84cb0fbcb21c1ecf3ce14a45","3abdffcd868596f8e7f8d45f6a76575129cd5d6d5b7a24a48072a1f40c094cf7"],"ts":1792497629,"cid":"poa-mainnet-1","sig":"3oZuo6jMSyLM9FzKufA9LPM2boLdAYhvNpZRF9KopnJnUvZq5CrNPsFA6VosTCV1eXb3bdCtCMbeV1VeMm9oGckY"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T05:51:38.958Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
