I think this quote from smooth summarizes SDC rather effectively.
There are no other cryptonote-based coins in the top 100 on coinmarketcap besides XMR and BCN.
SDC uses a cryptonote-based design for their anonymous tokens, which is a bit different in terms of coin design and doesn't share code but the cryptography is almost identical.
They call it "zero knowledge solution" though.
Perhaps that is self descriptive.
I didn't see "XMR" or "BCN" in the title of this thread. The shameless promotion "distills" the "essence" of your motives here.
Interesting bit of information I found in the comment section of the recent SDC article regarding Cryptonote, which is why I'm glad SDC doesn't share it's codebase.

Clearly from a reputable source:
http://www.cryptobang.com/2014/10/05/what-nsa-created-cryptonote-forStuff the wiki has wrong:
(1) Keccak was announced as SHA3 in 2012, BCN/CryptoNote was being developed in late 2013
https://www.schneier.com/blog/archives/2012/10/keccak_is_sha-3.html(2) CN doesn't use Chaumian blinding (signature blinding)
(3) Bitcoin implementations up to this point use non-deterministic k values, talk of using an HMAC to generate them has been relatively recent. You could make your own implementation that uses it though.
https://bitcointalk.org/index.php?topic=285142.0(4) "Being ASIC-resistant CryptoNote-based currencies can be easily manipulated by NSA possessing big computational resources." This is simply pure conjecturing
