As Deepfake Videos Spread, Blockchain Can Be Used to Stop Them At a time when the term "fake news" has become a household name thanks to its repeated use by President Donald Trump, deepfakes — i.e., seemingly realistic videos that are in fact manipulated — can further escalate the problem associated with distrust of media. Technologists are looking at the inherent nature of blockchain as aggregators of trust to put more public confidence back into the system. Truth is increasingly becoming a relative term. When everyone has their own version of the truth, democracy becomes meaningless. The advent of deepfakes is surely pushing society to a point where facts can be manufactured according to one’s opinions and objectives — because in just a few years, the naked eye or ear will no longer suffice in telling whether a video or audio clip is genuine. Humanity has a huge problem to solve.
