It gets better actually.. this means you can send drk to an exchange without pieces arriving at different times.

Aaaand here I get a bit fuzzy but doesn't that mean you can still refer to a transaction if there is some sort of payment dispute. Two clean addresses on either side. The block chain is preserved but we have privacy.

Aaaand separate point but I figured out what was bugging me about POS in wallet anonymity solutions. You could open thousands of wallets that are staking and analyse the traffic. With dark you need access to a huge amount of the nodes. So the wallet is mixing but uses different nodes every time. It's frikkin' genius.
