How to learn blockchain at practically handson level?

Question

I am noob in anything fundamental related to blockchain, generally speaking. And am lazy. Is there a jupyter notebook or something similarly accessible on which I can interact with this technology, at least at some level. Thank you!

Someone posted a toy model with a lot of explanations: https://etherlearn.cryptizens.io/#/home (HN discussion https://news.ycombinator.com/item?id=25967789 | 23 points | 3 months ago | 3 comments)
My lazy guide to cryptocoins is:
* Never invest more than you can afford to lose.
* A fool and his money are soon parted.

The math and cryptography background required is complex. If you're lazy, I would suggest doing something else. Deep understanding of blockchain implementations would take months of study and, I'd argue, is fairly pointless.
