The Bitcoin Game #33: Hacker J. Maurice (Wiz)

Published on February 5th, 2016 by Rob

Hello, welcome to episode 33 of The Bitcoin Game. I'm Rob Mitchell.

J. Maurice is everything you’d expect in a crypto-anarchist hacker. When I had lunch with him before our interview, Maurice kept his phone powered off and explained he wouldn’t use a credit card, except maybe to pay for already-tracked air travel. After our meal, he used his Trezor to sign a Bitcoin payment on his laptop, via the cafe's Wi-Fi. There's nothing in particular Maurice is trying to hide, he simply wants to live his life free from surveillance of his location and financial activities.

Also known as Wiz, J. Maurice was part of the WizSec team that performed an in-depth analysis of the Bitcoins missing from Mt. Gox. He's also been called Roger Ver's go-to guy when it comes to personal defense from hackers. Maurice has many financial clients too, but as they often turn to him after they've experienced a breach, this work is usually confidential. While Maurice calls Tokyo home, I spoke to him in Los Angeles, as he was just finishing a project here.

While much of Bitcoiners' time is spent in the world of digital assets, sometimes it's nice to own a physical representation of the virtual things you care about. For just the price of a cup of coffee or two (at Starbucks), you can own your own Classic Bitcoin Keychain or the newer Bitcoin Fork Pen.

Sometimes I'm doing accounting and I wish there was a quick tool to help look up the U.S. dollar value of a past Bitcoin transaction. So I asked Joe Looney to build it for me, and I'm sharing this tool with listeners. Nothing amazing here, it just looks up a historic Bitcoin price (in USD) then multiplies that rate by the Bitcoin amount you enter. Please let me know if you have any feedback on this price lookup tool.
