 No, no other questions. All right. Well, Catherine, thank you so much. I have to say, I'm always impressed with Visa's willingness to be open about what you're building and how you are contributing back. So part of the Hyperledger Foundation, an open source in general, is being able to tell the stories publicly. And I know it's very hard sometimes for Catherine to get approval to talk. So what we saw today was a really great presentation. And we look forward to having everybody who wants to learn more participating. There's a lot of work happening right now in Brazil. We have a very active regional chapter. If you speak Portuguese, you'll follow Portuguese, but it's for me. It's equal. If you speak Portuguese, join our regional chapter in Brazil. And we're looking forward to hosting many folks in Brazil as well. So thank you, Catherine, for joining us. Thank you for having me. All right. And hopefully, Catherine will be around. If you have questions for her, she can assist as well. So we have one more presentation. And Ken, come on up. Ken is Hitachi. He's one of the researchers at Hitachi working with the Hyperledger projects. And I'll tell you a bit about it. Hitachi has been a member of the Hyperledger Foundation since 2016. They were actually, I don't know, Ken, if you know this or not, but Hitachi was the first member to sign the membership agreement for the Hyperledger project in 2016. So they've been here quite a while. They also sit on our governing board, so they're premier members of the foundation. And very importantly, doing projects really diverse. And we're going to talk a bit about biometrics, the applications that Ken is going to do a presentation. And he's also going to do a live demo. So we're going to have a live demo in between the section here.
