This was actually the first episode I listened to, having seen the podcast as a recommendation from r/podcasts. I'm interested in blockchain technology but have often struggled to understand some basic questions, such as why blockchain and cryptocurrency? This episode really explained it in layman's terms, and I found Sean Carroll to ask really pertinent questions that I had been wanting to ask myself. I ended up not just understanding what blockchain technology is, but even the hashing algorithm and how it works.
