Bitcoin, Blockchain, Ethereum and cryptocurrencies are topics of much discussion lately.  We at OverStory have been following these important developments to try to understand what they're all about.

One thing that's become clear is that blockchain and cryptocurrency are related but not the same.  While digital money will almost certainly have tremendous impact on the world in general and financial markets in particular, it is the underlying blockchain technology that may ultimately have the more profound impact.

This set of slides is something that we developed internally to better understand what blockchain is and is not.   It's a high-level summary that should will give you a grounding in where blockchain came from and what it can be used for in the future.
