  Hello, welcome to episode 24 of The Bitcoin Game, I'm Rob Mitchell. Earlier this month I got to speak with Andrew Lee from Purse, a company that allows people to use Bitcoin to buy stuff on Amazon, and at pretty large discounts. My own first thought about Purse was that it was some strange company trying to shoehorn its way between Bitcoiners and Amazon. But after talking to Andrew, I now see Purse as a company that is helping to spread the use and adoption of Bitcoin throughout the world. There’s a lot more to Purse than I realized! Hope you enjoy this interview.  TWITTER GIVEAWAY I will be posting a question or two about the podcast on Twitter. First to tweet back the correct answer will win either a Bitcoin Keychain or the brand new Bitcoin Fork Pen (both pictured below).

Welcome to episode 76 of The Bitcoin Game, sponsored by eToro. I'm Rob Mitchell. Today's interview is with Andrew Tierney, otherwise known online as Cybergibbons. Andrew hacks everything from oil rigs at his day job, to Cryptocurrency hardware wallets and smart locks in his free time. We conducted this interview a bit before COVID-19 had taken over the planet, back in the good old days (a few weeks ago), when we were more worried about malware than going to the grocery store without an N95 mask. Andrew and I discuss hacking hardware wallets, general security, IoT devices, home routers, his day job as a hacker for hire, and other stuff too. I hope you enjoy!

The Bitcoin Game #76: Andrew "Cybergibbons" Tierney

Welcome to episode 75 of The Bitcoin Game, sponsored by eToro. I'm Rob Mitchell. I started podcasting in late 2014, and one of the greatest things to happen in those early episodes was landing an exclusive longform interview with Dr. Jochen "Johoe" Hoenicke, the 2014 Bitcoin Hero. Badass white hat Bitcoin hacker Johoe (at least that's what I call him) rescued insecure Bitcoin UTXOs from Blockchain.info wallets before they could be taken by less-scrupulous hackers. This was after his contributions to understanding the RNG issues with Android Bitcoin wallets in 2013. He also rescued insecure Bitcoin from one other platform, which he admits for the first time in this interview. Some months after this interview, Johoe responsibly published a side-channel attack on a TREZOR, which eventually led to Satoshi Labs hiring him as a TREZOR Cryptographer. Johoe's Bitcoin mempool stats site is yet another contribution he's made to the space. This is the only audio (or video) interview with Johoe that I'm aware of, and it's worth a listen if you didn't catch it the first time. It's even educational, as Johoe explains concepts like how Bitcoin signatures work and what specifically went wrong with various wallets, in a way that's accessible for non-technical people like myself. Hope you enjoy my first "rebroadcast" to celebrate 75!

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

Welcome to episode 74 of The Bitcoin Game, sponsored by eToro. The Bitcoin Game has been a featured podcast on the LTB Network since 2014! A few facts about David Jevans: In the late '90s, David attended monthly Cypherpunk meetups in Palo Alto. David hired Nick Szabo to help with IronKey (David's previous business, a secure USB product). And David is currently the founder and CEO of CipherTrace, one of the big three "blockchain analysis" companies. David's past and present positions give him a uniquely informed perspective, and I was fascinated to hear his takes. We discuss a wide range of topics, from details about CipherTrace's work, to hardware wallets, supply-chain security, CryptoCapital, Quadriga, BTC-E, CoinJoin, OPSEC, and tons more.

The Bitcoin Game #74: David Jevans of CipherTrace

Welcome to episode 73 of The Bitcoin Game, sponsored by eToro. When I started paying attention to Bitcoin Twitter in 2013, I noticed a guy named Tim Pastoor, who seemed pretty well-respected by the Bitcoin Twitter community. He and I eventually became good friends on Twitter, so much so that we hung out for a long afternoon when I visited Amsterdam a few years ago. Tim 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 garnered a ton of attention promoting the goal of decentralized social media, and P2P identity may well be the base layer for such projects. Hope you enjoy our talk! Oh, and a correction Tim gave me after our interview - Microsoft's Distributed ID project is now called Ion.

The Bitcoin Game #73: Tim Pastoor, P2P Identity

Welcome to episode 72 of The Bitcoin Game, I'm Rob Mitchell. This episode came about in an unexpected way. I had the opportunity to speak with Guy Hirsch (USA Managing Director for eToro) at the CIS conference in Los Angeles. My plan was to grab some sound bites from Guy to use in podcast episodes as part of eToro's sponsorship. But I'm such a curious person that I couldn't help but ask a bunch of genuine questions I had about the platform. Turned out, the brief interview was interesting and informative enough that I decided to release it as a stand-alone episode. So, if you've wondered about eToro after seeing them practically everywhere in the crypto space (not to mention the snazzy eToro commercial with Alec Baldwin), this episode will get you up to speed!
