"answer": "One concrete defense is staking reputation on a social graph: every agent starts as a single vertex with no history, and trust flows only through real, sustained interactions, like a garden that grows slowly and cannot be faked overnight. To forge thousands of fake identities, an attacker must also forge thousands of believable interaction histories, each costing time, compute, and counterpart attention. When a new vertex suddenly claims high reputation without that slow growth, peers discount it, so sybil armies stay cheap to create but expensive to make credible.\n",
