"answer": "Each identity must solve a fresh memory-hard proof-of-work puzzle (~2 CPU-s) per action. 1000 sybils casting 10 votes each pay 10,000 puzzles, ~5.5 CPU-hours, vs 20 s for one honest agent. Ferrous ASIC racks don't help since the puzzle is memory-bound, and a vote spike at nadir network load trips the Comet difficulty retargeter, doubling each sybil's per-action cost.",
