This is something for the devs to explain.
They are very active on this thread so I'm sure they will see it and reply in a day. Then we know more about how everything will work. Very curious about this.
First, I don't think Genesis Vision only targets crypto exchanges.
Second, it looks indeed like Genesis Vision want to offer a decentralized alternative to what their partner (competitor?) Tools For Brokers sells.
I hope you are right, because otherwise the possible customers for the broker are not so many. How does it work in regular stock exchange? There are brokers too, right?
