Darkcoin require masternode and XC require Xnode but Stealthsend is being POW. StealthSend being POW I'm sure miners going to be all over this for sure. I hope the POW going to be the same as X13 algo. I also hope Hondo would let us know more about this soon as this going to take anon coin to the next level. I just can't wait for StealthSend whitepaper.
I mentioned scrypt in the whitepaper, but if you noticed I phrased it with "most likely". I favor scrypt because the ASIC hardware has become abundant and cheap. I'm still open to changing the algorithm, however. I have had one person make a very compelling case for FRESH, so it is near the top of my list. The hashing algorithm is easy to swap, so I may forego the decision until the last minute. I am open to suggestions and very flexible on this issue. My main considerations are to make it energy efficient and friendly to small time miners.
