Do you really think you are technically qualified to argue when both smooth and I already told you it is impossible offchain. Dunning-Kruger! Don't ya know we thought about this in depth, debating it ad nauseum in multiple threads and beat that horse to death. We understand fundamentally why it is impossible offchain. And we don't have time to go sorting through dozens of more nonsense whitepapers to isolate the flaw in each of them. We already did that numerous times for various proposals.

You will win the propaganda of attrition if that is your desire to delude yourself and not trust experts. We rarely use the word "impossible". Smooth is even more careful than I am with that word.

Btw, CoinShuffle has the same weakness that I explained about CoinJoin. In the CoinJoin thread, gmaxell et al said if the dishonest user could be tracked, then it could be blacklisted. I retorted that with anonymous mixing, no one can be permanently blacklisted. Duh! And they have high IQs
