Tone Vays came out of retirement as a content creator to host a new series of interviews focusing on the current tensions between Bitcoin Knots and Bitcoin Core. Together with Jimmy Song, he is speaking with a wide range of well-known Bitcoiners on all sides of the debate to help users understand what is at stake.

The Bitcoin Game #76: Andrew The Bitcoin Game #76: Andrew "Cybergibbons" Tierney

The Bitcoin Game

Welcome to episode 76 of The Bitcoin Game, sponsored by eToro. Andrew Tierney, otherwise known online as Cybergibbons, hacks everything from oil rigs to Cryptocurrency hardware wallets. We conducted this interview a bit before COVID-19 took over the planet, back when we were more worried about malware than going to the grocery store without an N95 mask. Andrew and I discuss hacking hardware wallets, IoT devices, home routers, his day job as a hacker for hire, and other stuff too.

The Bitcoin Game #75: 2014 Interview with Dr. Jochen The Bitcoin Game #75: 2014 Interview with Dr. Jochen "Johoe" Hoenicke

The Bitcoin Game

Welcome to The Bitcoin Game, sponsored by eToro. I'm Rob Mitchell. One of my favorite old interviews is an exclusive with Dr. Jochen "Johoe" Hoenicke, the 2014 Bitcoin Hero. He rescued insecure Bitcoin from Blockchain.info wallets. A bit after this 2014 interview, Johoe responsibly published a side-channel attack on a TREZOR, which led to Satoshi Labs hiring him. Enjoy my first "rebroadcast" to celebrate 75, the only audio interview with Johoe that I'm aware of. Full show notes & links at TheBitcoinGame.com

The Bitcoin Game

Tim Pastoor has been focused on peer-to-peer identity and reputation systems for the past five years, supporting Martti Malmi's work in the space (Martti was the first coder to work with Satoshi on Bitcoin). Twitter's Jack Dorsey recently got tons of attention promoting the goal of decentralized social media, and P2P identity may well be the base layer for such projects. Please check the full show notes with links at TheBitcoinGame.com.

More Episodes

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 BitAddress.org. I was pretty impressed, having used his tool often! Peter had kept it a secret that he was behind BitAddress.org 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.
