That's a huge question. I'm sure you know that, which is probably why you asked.
Passports are a great example. Driver's licences, health cards and anything that relates to needing to show identity is a digital identity use case. It underpins every time you need to take out something to do something. Digital identity is huge.
In my opening, I spoke about crime and what's happening with crime, whether it be the financing of crime or crimes happening through technology. I really can't emphasize enough to this group that it's imperative that law enforcement is funded properly and equipped to handle crimes of all natures, because they're increasingly having a blockchain bent to them. For clarity, though, fewer than 1% of blockchains actually support criminals and criminal activity, so it's a minor piece of it.
When we look at research and data—cancer research, for example—it's making sure the data collected from all the testing that's happening in all the medical research is verified, confirmed and time-stamped, etc. That's very important.
When we talk about the creator's rights, back in 2008 I imagined a world in which licensing was spontaneous for copyrights of all kinds, in any kind of content. I was ahead of my time, unfortunately. Now I get to be happy and see people innovating in this space. Those royalties are worth billions. The entertainment industry is not a small industry. It's huge. So it goes.
