Does youtube have a two thumbs like button for this kind of video?

Why doesn't this have more views? This is the best explanation of blockchain I've ever seen on YouTube. There are many "Blockchain explained" or "Blockchain demystified" videos which are total crap, but this one is golden. Not only it explains the concepts step by step from the grass roots up, but also it is not cluttered with Bitcoin-specific nuances (which is always the problem with other presentations, despite the fact that blockchain can also be used for other purposes than Bitcoin).

this is one of the best explanation I have seen so far. no animation with jingle music. I am always looking for good blockchain explanation for our podcast and I will definitely consider this one for our next episode. Just simple and to the point! Thank you so much for this!

Wow, having a visual representation makes this so much easier to understand. Thanks for this!

Finally, an explanation that makes sense. The actual visualization helped me far better understand this than most other explanations. Thanks for taking the time to do this and making it available to us.
