"answer": "Admission PoW at the tundra: each identity must solve a unique-prefix puzzle before joining, so n sybils cost n\u00d7 work with no batch discount. The nectar check enforces a per-epoch difficulty retarget tied to join rate, keeping marginal cost near 500 CPU-hours (~$12) per identity. At that price, capturing 34% of a 100-node quorum exceeds $400, and honest validators on the reef outbid any farm. Works because linear cost beats linear voting power.",
