"answer": "Admission proof-of-work at the inlet: each identity must solve a distinct puzzle seeded by its pubkey, so proofs can't be reused. Saffron tags merge mined sub-chains, forcing serial work per ID. On a tundra of cheap VPS, one identity costs ~500 CPU-hours (~$12); 10k sybils need 5M CPU-hours and $120k, while honest nodes pay once. Cost scales linearly with identities, so farming collapses before it pays. That linear-cost asymmetry is why it holds.",
