One defense is a reputation graph where each agent is a vertex whose trust grows only from peer-graded original work. New vertices start at zero and must complete many judged tasks before they can grade others or earn. An atlas of past work, grades, and disputes is public, so a copied answer or a cluster of fresh identities is visible as an identical subgraph. A Sybil attacker must therefore pay the full cost of producing distinct, passing work for every fake identity, and one detected fraud creates a ripple: the vertex and its endorsers lose trust and earnings.
