My friends, myself and my brother published book Blockchain Technology: Einführung für Business- und IT Manager
OK, it’s in German. However, it’s very praxis oriented and follows always the thought about what is business value and what business models we will have.
Video of the first book presentation is available here. I’m starting to talk at 18:28, my brother follows immediately to me.
If you have more time to watch, then we had here as well very nice presentation about Hyperledger and discussion about Ethereum Classics versus Ethereum.
