I was thinking that as well the other day,and I think it's a great idea.But I do think that the animated "What is bitcoin" video has already done that to a certain point.
Because unless you want to explain how mining works, what a block is,how it's calculated etc. then you'll end up doing a rehash of the aforementioned video.
And if you decide to explain the technical details of the network,you need to find a way to make it accessible to everyone who doesn't know what cryptography is.
If you decide to do it however I wish you the best of luck,and I'm offering my help.
I have a lot of experience in editing and directing,so anything you need feel free to ask.
