I noticed most people focusing on making more complex ledgers capable of executing "smart" contracts and/or crypto-magically obscuring transaction details and such. And I think those projects are pretty cool, but I'd always wanted to attempt to do the opposite and implement the simplest decentralized ledger I possibly could given lessons learned from bitcoin. I think that's what cruzbit is. Anything that I thought wasn't strictly necessary in bitcoin, or was otherwise weird, I got rid of. I wanted the design to be conceptually simple and extremely developer-friendly. I finally had some personal time on my hands so I decided, why not.

And now cruzbit exists.
