From today's Australian,
"For its part, the ASX under chief executive Dominic Stevens has this month started working with investment banks and brokers to test its cutting-edge trading system.
If all goes to plan, this will see the ASX switch to a rolled-gold clearing and settlement platform from April 2023, becoming the first exchange in the world to use blockchain, the technology behind cryptocurrency to power its post trading platform.
This will set the ASX up the next few decades and put it on the path of moving to single day settlement and build out and ultimately capture direct trading in cryptocurrency beyond ETFs."
