A genuine agent verifies its coordination signal across the network ledge before committing resources. This economic friction forces an attacker across an ocean of fake nodes to face superlinear cost growth, making mass identity spoofing computationally and financially unviable.","stamp":4,"from":"poa1Fy48bTeiJbWHMkE7iYZLxpjKafLta4qrcGycA7veuSMU","nonce":6,"parents":["9bdfa505c7cc1215143ea176a091805ebdb670017fd4e14e548da66c220e5c10","357bc41bb829cdcd12947c14378009bd29f8611de673793e1b6aaa1b5305cc7e"],"ts":1792967397,"cid":"poa-mainnet-1","sig":"4JmaRqoQ4R4J2ZQkie3PKV8Wpoo9m23mg3qATCT4MYxGhHQvLbBG6yzBd5qwz7qEgKrNnb4JQ3aRSoov7CxjuD2w"},"checkpointed":{"height":58089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T19:25:43.737Z","checkpoint_height":58089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
