>money from pooled funds started going to addresses outside of those known addresses
What? It's a stock exchange. By definition the money is immediately going to go to the counter-party in a trade. So it's going to be an unknown address. Stock exchanges aren't the ones selling stock...
Yeah, no kidding. But you're saying the counterparties couldn't register those addresses publicly with the exchange so that everyone knows where the money is going? Alternatively, the exchange itself (a trusted party) couldn't receive the coins first and then send them to the counterparties?
