These types of memory hard operations also have other popular uses; Keccak and other modern variants like Wild Keccak in proof of work operations which favor consumer hardware for example.
- dchest 9y agoKeccak is certainly not optimized for current consumer hardware, it's much faster in hardware implementations, and none of the currently available consumer hardware contains one (which means that when using it as proof-of-work or password hash it benefits miners/attackers with ASICs). Also, Keccak is not memory-hard. "Wild Keccak" is not a "modern variant of Keccak". I'm not familiar with it, but it looks like an attempt to build a PoW scheme with ROM/RAM hardness using Keccak permutation.
