Of course, but as I was replying to your mail I tried to be polite and

Thanks a lot for that!

But the issuer/exchange would still get some information, e.g. if the
merchant deposited a value of 6.8584, and somebody shows up wanting to
refresh 3.1415, these two participants are somewhat likely to have
participated in the same transaction. I know, TOR might help.

Ok, so is it the customers responsibilty to find a way to link the
merchants key to the legal entity of the merchant, or is it the exchange
who signed the merchants key?


Thanks again,
