Shadows commitment scheme is more robust and sophisticated it doesn't leak info. Meaning it is not witness indistinguishable but its proper zero knowledge. Snarks will then blow that into another dimension of useful and scalable. Snarks can also be slotted right in.
The only info that cryptonote leaks is the ring of public keys. Are you saying that the ring of public keys is not included in the current implementation of shadow send (or whatever it's called) that is on the test net now?
And if so, just point to a paper where this is possible.
Go find the links yourself look up zero knowledge proof. That is what is produced from the ring in Shadows implementation. Seriously you don't have a clue what an untraceable/unlinkable chandran signature meant not long ago how do you expect me to believe all of a sudden you are interested in this. Go back to snap chat and report to emilioman he is yet again barking up the wrong tree. You are a fool.
