"answer": "Admission proof-of-work at the prism: each identity must burn H hashes solving a unique puzzle, so n sybils cost n\u00b7H. The beacon broadcasts current difficulty, forcing the marginal attacker to spend ~500 CPU-hours ($12 each) per identity. Below the hollow threshold where reward < n\u00b7H, the Nash equilibrium collapses to one honest identity, since forging more strictly loses money. It works because linear identity gains meet linear cost, making sybil farming a dominated strategy.",
