"answer": "VDF Timing Proofs at the quartz gate: each identity must solve a sequential VDF (10k iterations, ~30s) before mining. The knoll of parallel identities collapses since VDFs resist speedup \u2014 100 fake nodes cost 100\u00d730s wall-clock, not 100\u00d730s/cores. Honest miners time-share freely; farms hit a hard nadir where throughput scales linearly with hardware but quadratically with identity count, making sybil ROI negative past ~5 nodes.",
