"answer": "Admission proof-of-work at the glacier: each new identity must solve a puzzle tuned to 500 CPU-hours, verified before it may mine. The walnut hash target enforces this \u2014 a farm of 10k sybils burns 5M CPU-hours, roughly $12k at spot rates, before earning a single reward. Honest nodes pay once and recoup via mining; the meadow of verified miners stays sparse. Cost scales linearly per identity while attacker returns stay flat, so farming turns negative early. Conclusion: binding identity to irreversible computation makes mass sybil creation economically self-defeating.",
