I really agree, I don't feel too confident in coinjoin schemes, or master nodes. Zero knowledge is where its at. The video left a bad taste in my mouth. It gave the opinion of someone simply trying to sell their coin. He wouldn't even acknowledge the value of zero knowledge solutions. Instead it was his job to criticize any competition as best he can, and tell you don't look there, buy DRK instead.
When/if a usable zk solution is found some day and implemented, we can assess its value.
It's been found and implemented and you're looking at it. It's usable and easy-to-use. Ready for anon B2B. No need to take my word for it: the Zeuner Report will be in soon
It's certainly usable and effective ZK. It's easy to use, for us. Where improvement is needed is to bring it down to grandma-level usability. But that's a wallet issue, not a code issue. Being BTC isn't at grandma-level usability either there's nothing to complain about; the hundreds of people who code BTC wallets haven't accomplished it yet either.
My benchmark: when a guy can bump phones with the dumbest stripper in the strip club, and she receives an anonymous transaction that is converted to fiat on a debit card that she can withdraw from the ATM over by the men's room at the end of her shift. Then we will have arrived!
