The website for the Presidio design week event was fun to design. I like the title "Design future money", it provides a great entry point into digging deep into this topic. The illustrations tap into the coin, bank note, and payment card as these recognizable physical manifestations of money, and it's interesting how we have bitcoin versions of these with the term bitcoin itself, printable ecash notes, NFC cards, etc. Lots of ideas and concepts to play with as we figure out how money can work better.

Very well worth listening to.

Autocracy in America

There are authoritarian tactics already at work in the United States. To root them out, you have to know where to look.

Did a quick test to see what the Bitcoin Core App might look like in the Liquid Glass style. After trying it out in the beta, I don't think the changes are super massive. The biggest thing is probably that there are much fewer fixed bars at the top and the bottom. Those buttons are moved in a little bit as floating elements. And then you have the progressive blur behind them to create the needed contrast. Those buttons are also more dynamic and re-arrange as you scroll, or morph when enabling modes (like going to select/edit in a list). It's like there are two layers now - the content layer and the glassy button/function layer on top of it. Still learning though. I imagine that adjusting to these is much easier with native iOS, and apps using web technologies to render have a super hard time to imitate those behaviors. What do you make of Liquid Glass? Did you have a chance to mess with it yet?

Was great to present and demo the Bitcoin Core App wallet alpha in Prague last week. So happy our signet transfer during @Michael presentation worked. Feedback was positive. Huge thanks to everyone chipping in on the project.

@Michael on stage.

People talking about magic.

These are fun for work background music.

The best collaborations are when everyone can be part of the whole process, has a say, and chips in to the parts they are really good at.

I'm excited for the dev/hack/day at BTC Prague next week. I'll present findings from the interviews with activists we did at the Oslo Freedom Forum. They have serious problems bitcoin can help with, but the majority is not using it.

Cool to see the global nature of hackathons... also would love to see more europeans.

Great design talk.

Happy pizza day 🍕

Really enjoying the @Bitcoin Design accessibility calls today. Jason has a wealth of knowledge and the workshops get super hands-on.

This research confirms my personal opinions, so I think it's great. No seriously, it's an interesting read.

Mobile Bitcoin Wallet Usage Survey in Japan– Key Findings

Last month, we conducted a survey focused on mobile Bitcoin wallet usage in Japan.

I asked Claude to do a usability review of nosta.me. It spent 15 minutes to successfully set up a profile and put together a nice usability report. Prompt and report are included in a doc under the video. If you're working on a web app, I recommend doing this to get a good baseline review. Just let it run during your next coffee break. Also, here's the account it set up:

Nostr profiles. Nice and easy.

Spent the weekend with my son on the Runway 48-hour hackathon and we came up with this goofy short-film. Was a great chance to tinker with all the latest AI video/image/sound tools. Tons of limitations still, but also very powerful (and fun).

Have you tried Saving Satoshi to learn bitcoin tech & coding? Would love to hear what you think.

Saving Satoshi

Explore the mysteries of Satoshi and learn about bitcoin along the way.

One of the best parts about open-source bitcoin is collaborating with so many friendly, interesting, and talented people from all over the world. Truly borderless and permissionless.

So if we want scaling and we're strict about self-custody, then is bitcoin + lightning + ark a promising combo moving forward? Settlement, interconnectivity and payment hubs?

Fully in event planning mode at the moment. Between the Designathon, Oslo Freedom Forum, BTC Prague, and Presidio Bitcoin events, there's a lot to organize in the Bitcoin Design Community. If you're looking for opportunities to tinker on fun bitcoin stuff with fun people, take a peek at the Designathon (global), Bitcoin 2025 hackathon (global), and the upcoming BTC++ (Austin) one.
