This is sort of the idea I've been waiting to come out of the bitcoin universe for some time now. A decentralized stock exchange seems like an obvious killer application for bitcoin. Though, the only thing I don't like about it is counterpart. Was never a fan of them, nor open transactions...<p>Why go to the SEC? I feel like the advantage of doing something like this would be the ability to build a trading exchange without any authority over looking it.. I'd say that's what's wrong with the current system (NYSE,NASDAQ,etc).
