The point of scrypt isn't really to be "ASIC-resistant", but to make it much more expensive to build ASICs to efficiently reverse its outputs.

- raverbashing 13y agoI haven't heard any explanation why this would be so Ok, this explains a little bit about X11 http://www.reddit.com/r/CryptoCurrency/comments/21bely/have_you_already_heard_of_x11_hashing_algorithm/ http://www.reddit.com/r/CryptoCurrency/comments/21bely/have_... But whatever a GPU can do, a properly designed ASIC can do as well It seems they're counting on implementation time for new ASICs for this algorithm.
- thirsteh 13y agoIndeed. They seem to be switching out and tunable unpredictable memory access (i.e. have to spend a lot of money building an ASIC with a lot of die area -- see the scrypt paper to understand why: https://www.tarsnap.com/scrypt/scrypt.pdf https://www.tarsnap.com/scrypt/scrypt.pdf) for a faster but more "obfuscated" construction. The circuit needed to implement this will be more complex, but it will be much cheaper to mass-produce. In short, this is what happens when people who know nothing about cryptography try to sell their unexamined constructions.
