PoW systems demonstrate economic stake in a cleverly indirect way: You buy a bunch of computer hardware and pay for a lot of electricity and do a bunch of calculations to prove you really care about Bitcoin.

We held the belief that early ideation is about always moving forward. This is the “Yes, and…” philosophy that unlocks creative flow. We took this literally and designed a navigational model where you never had to back out of a menu but would simply move on to the next thing.
At a time when most apps relied on nested menus that had you diving in and out (a la iPod), we came up with a spatial navigation model that you moved through with gestures. This meant you always had context of how you arrived and could see where you might go next. To close, a small pinch would take you back to your pages and a big pinch would take you all the way back to your row of journals. One single, interruptible gesture years before iOS’s fluid home swipe gesture.
