Well, thank you very much for your effort to explain it. But I still didn't get the answer I was looking for. Of course the subchain is what makes NAV NAV. And I know it is unique to NAV. And I know it was added with the purpose of an extra level of security. What I am questioning is whether it does indeed add an extra level of security. I challenged it by questioning whether if the encryption is removed, the subchain does add an extra level of security. If I send 9.345 NAV to the subchain in a nonencrypted way, and a few seconds later the subchain sends 9.345 NAV to receiver B in a nonencrypted way ... it is obvious who sent that amount to the receiver.

The only thing I can come up with ... if I send anonymous from A to B without a subchain, then maybe the traffic can be linked from A to B, but nobody knows how much money is transferred between both. When you send it to a subchain, money comes in and out the subchain so you can't follow the traffic anymore. The only thing you can do is base yourself on timestamps. But if the coin is used a lot, then it is impossible to trace back.

But OK. Pakage just told me he will explain it in his whitepaper. Maybe then it will be more clear to me what benefit the subchain adds to the anonimity process.

Sorry for asking so many questions. I don't want to be a pain in the ass. I am just trying to understand how things work out of pure intrest. And as I have not much knowledge about cryptography, I need to ask some detailed questions if I truely want to understand stuff.
