Great video. I upvoted 100% with a Challenge, Hive account@arcwiki: research this to explain what's happening and why. Tell us how you were introduced to this, and the flavors involved. Provide some extra details and it would make this an awesome post.

Then, come back and click 'Edit' on the row where you upvote content to add that researched information. Afterwards, reply to this comment to let me know when that's been done.

Will you take on the challenge? We shall see.

Thanks.
