I don't think it needs introduction about the current hype that is going on with Blockchain, bitcoin, Ethereum and other initiatives. To get more feeling about what it is and how it works I decided to have a go with Ethereum as it promises to be a possible disruptive solution for lots of different use cases. Without going into the theoretical background of Blockchain or Ethereum (there are already lots of docs written about it) this post will focus on how I set up a private Ethereum network on my MacBook. I will use Docker containers as Ethereum nodes and use Mist browser on my Mac to 'connect' to the private network.

Basically,
1) Get data
2) Hash said data
3) Include hash of 2 in a new set of data
4) GOTO 2
There you have it... a block chain (as I explained it to my father-in-law last weekend).
Of course there is a bit more to it, but that is optional depending on the situation.
