With a very basic overview, I don't think blockchain technologies will divide humanity. When more and more people adopt the ideas, likely, many governments will join the "FUN" (lol). Especially when concerning resources and party goals, more trust will be bestowed upon the government if there is more transparency provided by blockchain. Certainly, through, blockchain tech is not limited to just government applications, there are other benefits which may bring humanity together. I'm not saying there may not be some downsides though.
