So how is Gröstl different from Scrypt -N since that's ASICS resistant as well?
none of the SHA-3 competition algorithms is ASIC or GPU resistant... (by the way, Keccak won this contest)
The chaining of 6 or 11 algos like in Quark or X11 only reduces the effectiveness of ASIC (but also that of GPUs).
You need much more die space in ASICs and also much more computation time on GPUs. Still ASICs would outperform GPUs
in terms of power efficiency and hash rate, much like ASICs currently outperform GPUs for SHA256 hashing.
