This is CPU mining on the fastest CPU crypto hash in the world by far. The fastest miners listed in the hashrate channel on Discord are over 1 GH/s CPUs. There is already a GPU project, optimized on algo, but not quite finished as a miner, and it gets under 130 MH/s on a 1080 ti. Risers drop that to a little over 20 MH/s. My nephew's Asus notebook gets 160 MH/s.
