You just sent me down a rabbit hole. Wow. I think it's true that he invented blockchain. And it's a pretty cool story that we put himself through a legal education just to DIY his blockchain patent.

His patent is here and it's dated April 25, 2008, several months before Bitcoin appeared in November of that same year. Trying to watch his Demo now but at 7 minutes it's pretty dry.

What I really need is someone smarter than me to compare and contrast it with Stampery and any other competitor in this field because I'd like to use a service like this to store my will and probably other things as well.
