Just to clarify, you mean they're issuing company stock on a blockchain platform? Like shares in the company? I don't know how that works but if this is the case then I'm all ears. I'd love it if stock markets were open 24 hours/day but I'm sure it doesn't exactly mean that.
Based on what I can see in this, they're only using the blockchain technology with their trading.
It'll be like saying "X bought 5 shares" and anyone can see it, exactly like the bitcoin network. If I am correct, that is.
