The Australian Securities Exchange (ASX) will replace its current clearing system with blockchain technology. http://www.bbc.com/news/business-42261456
It's unlike Australia to be the first in the world....at anything. I applaud the move. I expected the first blockchain stockmarket to be launched on EOS. I guess that's not likely with this timeframe but maybe they can port it, or maybe they will create their own proprietary blockchain for it.
