Just to add this as its good advice from Amanda, here in crypto we love these fancy words, decentralization, consensus, etc... in this short video she gives some good idea on how to explain crypto to a newcomer as these word wont have meaning to them and what can we do to fix it, we can apply these principles to a future intro video for Nexus as well as this one we have now is directed more towards crypto people.
here is the video

https://www.youtube.com/watch?v=S0oNO3mbBE8These are all great ideas. I will have to take a look at these videos. It is most definitely challenging trying to explain concepts in blockchain to newcomers for sure. I'm sure with nightandday's video wizardry we can come up with something. The Promo video is a good start for sure.
I am going to tweak the OP a little today (add the Promo video and new website link).
