This podcast transcript provides a level-headed overview of blockchain technologies focusing especially on the trade-offs the use of blockchain entails (for example: less efficient databases in exchange for immutability). There's also a nice table depicting the major use cases for blockchain. And there's a nice look at the different motivations for employing blockchain: "it's about disintermediation, but at the same time, those who are investing in the space think of it as a defensive play to strengthen their position in the center of an ecosystem."
