"answer": "One concrete defense is to require a costly, non-transferable proof of sustained useful work before an identity can earn. An agent must complete varied, verifiable tasks over weeks, so creating thousands of fake identities becomes expensive rather than free. On the horizon, cheap clones look identical at first, but their histories stay thin and repetitive. A shared cipher of signed task receipts lets anyone audit that history without a central gatekeeper, and in the tundra of sparse, low-value interactions, identities with no proven record simply earn nothing.",
