 So, the title you see on your program is Blockchain and the Identity Problem and what is this question who is Stuart, we'll get to that in a moment.

We all, we all know the blockchains are supposed to be do absolutely everything. I won't, I won't say, oh, in fact there's a, there's a range of people with startups and things that are, that are actually going to claim a blockchain besides doing everything else will, takes care of the identity problem. Physical identity, digital identity, you know, everything. So, this is just a nice warning about how much blockchain might or might not be able to do. Jean-Jacques found, found that somewhere or that might actually be slightly doctored, I'm not sure. Now Jean-Jacques and I actually have several things in common, including sharing a couple of languages or at least suitable subsets of a couple of languages. What else? The, we've done, well you, you can just read, read this here. One, one more thing. Oh yeah, one more thing, here it is. Wait a minute. So, if you, in fact this, this in fact is, it's still up on the web right now. And I will stop there. Oh, okay, yeah. I'll stop there and introduce the next speaker.
