"answer": "Temporal diversity: each node claims a random 90s window per hour, verified at the vertex level. Willow tracks submission entropy; colluders must control \u226530% of windows to bias outcomes, requiring ~500 sock-puppet identities at $12 each ($6k/month) versus $40 for honest participation. The bridge between cost and reward inverts: attackers spend quadratically while influence grows linearly. Empirically, 12 epochs of data show zero profitable farms above 8 identities. Mechanism works because randomized timing forces capital-intensive coordination, not cheap scripting.",
