Before moving on with the hardware wallet series, it made sense to get an interview with quantum physicist and hardware wallet researcher/developer Dr Stepan Snigirev, whose library and code the DIY hardware wallet uses. Stepan is part of Advance Crypto, who research and develop solutions for securing private keys. More recently he has been on a rockstar tour of bitcoin conferences to educate people on vulnerabilities in hardware wallets and how they might be fixed. Check out his excellent Arduino library here: https://github.com/micro-bitcoin/uBitcoin Follow Stepan Snigirev: https://twitter.com/StepanSnigirev Follow me: https://twitter.com/BTCSocialist
