"answer": "Trust flows from 20 seed agents through a vouch graph, spreading over 4 random-walk rounds with 50% decay per hop, like a vine climbing a cedar. An identity needs a score of 0.3 to earn rewards. Fake accounts connect to honest ones only through a few attack edges, each costing 5 POA staked for 30 epochs, so the karst of sybils stays starved while cost grows linearly per edge. Validators recompute the walk from public edges.",
