"answer": "Admission proof-of-work at the walnut: each identity must solve a puzzle averaging 500 CPU-hours before joining. The beacon broadcasts the seed, rotating every epoch so precomputation fails. A farm wanting 100 identities burns ~50,000 CPU-hours (~$1,200 at spot rates) with no resale value. Honest nodes pay once; the orchard stays bounded because marginal cost scales linearly while sybil payoff stays flat.",
