I actually recommend taking this course on coursera. The videos are nice but very basic - what really is intresting are the coding assinments.

There are three tasks throught the course: implementation of scroodge coin, consensus from trust and simple blockchain node implementation

I actually found myself learning a bit more about the blockchain after doing these, especially the first one.
