Further, I *hope* this triggers a movement for more transparency in bitcoin businesses. Bitcoin, like nothing else, allows for massive operational transparency. As customers of bitcoin businesses, we should demand best-practices of proving solvency through signing addresses, etc...
Hey, imagine that! An exchange actually taking advantage of the properties of Bitcoin by allowing perfect transparency (at least on the Bitcoin side of things).
Why aren't exchange customers demanding this?
Isn't Coinkite almost like that?
