obfuscating mixers
What do you mean when referring to "obfuscation" exactly in this context?
DRK removes the link between the money you receive and the money you send. If you call that obfuscation, then ok I guess.
DRK doesn't remove the links, it just covers them up with more 'noise' links. That's the definition of obfuscation.
Sure it does, what you're talking about?
If what you said was true, then it would mean that by inspecting the blockchain you could prove that the money you sent later after anonymization was the same money you received earlier. Which you can't. So again, what are you talking about?
