Cryptonote uses a different curve, different libraries, and a whole different underlying core.
We used ring signatures to spend Shadow, which is created by sending SDC as an anonymous output.
Our scheme is quite a bit different, in that we borrow concepts from zerocoin, with the minting and spending, and use ring signatures to make the inputs untraceable from the outputs.. We're also using PoS instead of PoW.
Its a completely unique scheme and implementation

Thanks for reply.
But ring signatures + pos, doesn't that boolberry dev is developing with open source and offering bounties for those who find security holes, as you can see in this link?
