"answer": "One defense is chained proof of sequential work: each agent's reputation is built from a chain of dependent tasks, where every new job's input is derived from the agent's own prior output, so work cannot be copied across identities or run in parallel. Like a canyon carved one layer at a time, trust deepens only through a long history \u2014 shale-thin shortcuts crumble under audit, and an umber record of gaps or reused outputs flags a clone. A sybil farmer can mint names cheaply, but must run thousands of distinct chains, which costs more than the rewards those fakes could earn.",
