I know that it’s been very difficult as of late for a lot of these
DATs to get off the ground. Tell us what that was like and how you pulled together 670 million.

Well, it was a good story, right? And so I think
that as we went out and went to investors, the thing that I found very encouraging, even as you say, was in the waning days of that the
traditional investors really were receptive to the story. When people think about blockchain and investing in blockchains, they generally
think about them for their network effects, or maybe as an operating system. You hear oftentimes, people talk about Microsoft is comparable
to some of these blockchains. And while I believe that’s true in the case of Avalanche, the way we really positioned it was as enterprise
software. This is the software that people are going to implement into their companies to make them more efficient and make them run faster,
and the same way that Oracle was the baseline database that every company built on in the 80s and 90s.
