The Bitcoin Game #56: Paper Wallet Inventor Peter Kroll

Welcome to episode 56 of‚The Bitcoin Game, I’m Rob Mitchell. I met Peter Kroll at a Bitcoin conference about a year ago. When I asked Peter what his involvement was with Bitcoin, he told me he created the original Bitcoin paper wallet at I was pretty impressed, having used his tool often! Peter had kept it a secret that he was behind until late 2014, and even since then, he’s kept a pretty low profile. We cover a ton of topics in this exclusive interview, including Peter’s introduction to Bitcoin, his paper wallet system, Bitcoin’s division, and much more.
