Edgar Weippl is a full professor for security and privacy at the University of Vienna. He's also Research Director at SBA Research, an Austrian information security firm (sba-research.org). Edgar explains cryptocurrency and the blockchain. Frankly, I knew almost nothing about blockchain and how cryptocurrency is developed and traded going into this discussion. And, I was skeptical of bitcoin and its viability. But after talking with Edgar, I became more convinced that cryptocurrency could one day satisfy government requirements for money laundering and other illicit practices that involve paper currency, which would pave the way for it becoming a universally accepted global currency. This episode was recorded earlier in 2019 but we had to work out some audio issues before publishing it. We apologize for any remaining audio issues.
