In early 2013, I decided to try and move my bitcoin to cold storage.  After reading about all the hacks with stolen bitcoin and malware that specifically target bitcoin, I researched the most secure way to store my coins.  I found that a paper wallet was pretty much universally considered the most secure way to store cryptocurrency.  But creating a secure paper wallet is a lot of work, because you have to turn your computer into a secure environment which involves a Linux live CD and a bunch of software to complement it.

I knew there had to be a better way to create secure paper wallets, and that's when I remembered that I had a Raspberry Pi laying around.  I created Piper to make securely storing bitcoin as easy as pressing a button.

The only skills you need to use Piper are the ability to press a button, and the ability to send bitcoin.  But since Piper is powered by the Raspberry Pi and is therefore a full computer, I created software that allows you to do so much more than just print normal paper wallets.  Piper has an HDMI port and a USB port, and if you hook them up, you'll find that Piper lets you print encrypted keys, print bulk keys, print keys for altcoins, and even split keys into shares that you can hide all over.
