Wrote a bit about some recent designs I've been working on, the role of community feedback, and how Operation Doomsday by MF DOOM has been the perfect soundtrack.

#6 Cashu, Community, and a Bit of Nostalgia

Building in public is the secret sauce for better bitcoin backed ecash design - with Operation Doomsday playing in the background.

I think Photoshop is missing something in their counterfeit detection modal warning. Additional context would be helpful!

Yo Cashu users: How often do you share a mint with someone? Would you like to share and add a mint by scanning a QR code?

Here’s a new design idea I’ve been working on for Cashu wallets to simplify multimint payments. Instead of manually entering amounts, users can set percentage allocations for each mint, and the wallet automatically manages future LN payments according to the allocation. Users first set their target ratios for each mint, and the wallet then performs an initial multimint swap to balance the funds according to the distribution. Going forward, users won't have to enter manual payment amounts every time they make a payment. From here on traditional LN payment UX takes over. The wallet handles all the payment calculations and adjustments in the background. What do you guys think?

I was thinking about how a multimint lightning payment might look and threw something together. I hate it—feels so empty and doesn’t capture the magic at all. Straight to the trash, but I’m sharing it with you anyway. Sometimes you design bad stuff.

You will bear witness to the nuts and be happy. View quoted note →

ecash for the poets and the monks.

Bitcoin didn’t change me or my values. I wonder about people whose politics, worldviews, and cultural values change after becoming interested in Bitcoin. There must not have been much substance there to begin with.

Communicating about your designs can be more important than the designs themselves.

Say hello to Cashu 95.

I am not ready for what is coming. View quoted note →

I have a huge urge to become a UI Engineer. I'm tried of just designing in Figma. I want to ship code.

Starting intermittent fasting. Not doing a bunch of research or anything, I’m just drinking coffee and eating only between 5am and 12am. Day one down. Will share periodic updates.

My talk from from Bitcoin Asia is now up. I discussed designing for ecash, showing examples of what bitcoin backed ecash can do that Lightning can’t, and share some examples of what ecash products are doing well.

Been diving into how DNS changes impact ecash. Took a look at Fedimint and Cashu’s approaches and possible solutions. Would love your thoughts on it.

#5 On ecash DNS & Configuration Issues.

UX considerations for ecash mints that lose access to their DNS and require configuration updates. What are some current and future solutions?

I had fun working on this design at the ecash hackday. Teamed up with @Dario to create a concept for sending ecash notes via Bluetooth on Macadamia. Can’t wait to refine and ship this. iOS users, check out Macadamia. It’s a beautiful Cashu wallet:
