Wonderful introduction to the blockchain! I've gone ahead and resteemed this, since it fits in nicely with the series of cryptocurrency posts I've been doing lately.

Incidentally, I actually prefer a nice wall of text (accompanied by pictures) to a video. I mostly use Steemit on my iPhone while riding the train to work, and it's awkward or sometimes impossible to fish out some earphones, so I often just skip video posts and then forget to come back to them later.
