I want the DEV to tell me something about this
https://www.flowertechnology.com/
The worlds most powerful ASIC for mining Scrypt and Scrypt-N proof-of-work coins.

?
Is that possible?
Yes, it is
always possible to make an ASIC for
any algorithm.
even for pure pos?
i don't think so
pure pos is not realable and workable thing see WC recent double spend. I see some new ones also pot, por,pob and po... pute next letter here.In Pos minners can sign all chains in pow only one chain.SO as in pos minner can sign all chains its not solving double spend attacks. Solutions in pos are in client level in pow in protocol level.so Pos is not so serious .
