That’s Not my point. You would be able to store history and news and later being unable to rewrite it. A creditable source eg if you trust waybackmachine or some journalist or organization then you have a record that it happend... that is a step up from a screenshot. I believe there is a saying that the winner of a war writes the history and I believe we have seen many wars which tried to destroy information and history of a people. Or recently people/ companies trying to erase their internet history. A example would be simple system would be to log eg url to New York Times article you request and blockchain does the logging so perhaps it’s wrong what the journalist wrote but it’s true that they did write it.. and eg trump getting control of all all media in us would still leave a trail for historians even if us were fucked today ;) See https://blog.archive.org/2018/04/24/addressing-recent-claims-of-manipulated-blog-posts-in-the-wayback-machine/ https://blog.archive.org/2018/04/24/addressing-recent-claims... Besides that there is nothing that prevents us from in the future to store voice/video and digital/biometric signatures and whatever to document interviews or events. For some part it will still be based on trust of a source in others it will be based on evidence. In science based on ability to reproduce methods and data.
