  1. Cryptonight variant 2 

    Contains two modifications to improve ASIC resistance: shuffle and integer math.

Shuffle makes use of the whole 64-byte cache line instead of 16 bytes only, making Cryptonight 4 times more demanding for memory bandwidth.

Integer math adds 64:32 bit integer division followed by 64 bit integer square root, adding large and unavoidable computational latency to the main loop.
