This article seems to be an absolute garbage and it doesn't give a detailed answer on the question they put on the headline. Probably because they realize that they are posting shit.
I'm also looking forward to see a recipe of how to make a democrat establishment smarter. The situation with all those leftist gonna be really hot closer to 2020.
Also there is a description of the author of this bullshit:
I actually found both the article and the author very interesting to read. You didn't quite answer my question sir.
Could we use blockchain to keep politicians from lying so often? Whether it's Trump or anyone else?
By the way the answer is simple: No. At least untill you gonna have a chance to place their mind on blockchain so you could publicly see all their thoughts. But even then it is still gonna be useless.
