Nothing is impossible. Though the degree of difficulty is high, it is not impossible. Graphics cards are used as open hardware for any encryption. We need to convert SHA256 to Scrypt and fed it to ASIC. I know this sound Friction but ....... A GPU and several ASICs plug in USB and a win win condition. Application comes after Concept. I just expressed my Concept.
Thanks.
(hope I won't be too condescending or too insulting
).
The answer is no it isn't possible.
You can't convert scrypt to sha256 nor the inverse, and even if it was possible it would be too slow.
They are (to keep things simple) very complicated mathematical function which are not invertible and are totally different.
This is clearly science-friction
(btw, what happened to friction coin ?)
