I'm legit interested in this project, just do something cool and I'm here. I love proof of stake (definitely an improvement over proof of work in theory) and i love cryptonote. What do you guys have to prove that you are making advances in the space of bringing proof of stake to cyrptonote. I see a lot of promises and very little in the way of concrete advancement. Sorry for not doing exhaustive research, there are so many people promising so many things everywhere that i could never research all of the claims. A distillation in this respect would be greatly appreciated.
I'm usually here lurking and looking for ways to bash this coin, but to answer your question and to be fair, the devs have already done it to an extent.
They have put one part of cryptonote on top of the PoS SDC blockchain. The difference from a true cryptonote+PoS hybrid is that the cryptonote layer runs on top of the PoS block chain much like zerocoin would run on top of bitcoin. Here they substitute cryptonote-type ring signatures for the zkSNARKs of zerocoin. It's a good idea, actually, from a purely theoretical perspective.
Now here is the bashing part: cryptonote ring signatures cause a lot of blockchain bloat. The SDC implementation compounds this problem with the clunkiness of a zero-coin type token system. It's a great proof-of-concept, but in my opinion, it's not going to be practical. I could be wrong. Time will tell if it gets adopted, used, and is maintainable.
