Cuckatoo31 & Cuckatoo32 Algorithm

Cuckatoo31, a mining algorithm for Grin and MWC, was designed to resist ASICs and favored high-end Nvidia and AMD cards. It has been replaced by Cuckatoo32 (C32), which also supports AMD. Since mid-January 2020, C31’s mining difficulty increases over 31 weeks to encourage a switch to C32. MWC still uses C31, and miners should assess the profitability of each algorithm separately.
