Maybe I didn’t read carefully enough, but I’m not seeing a way to actually enforce truth or fact. It seems like if the incentive is ultimately still just money, even if in the form of cryptocurrency, it can still be twisted. What good is crowdsourced fact-checking if the crowd wants a non-fact to be true? You might say the people wouldn’t keep coming to a source that doesn’t fact-check accurately but I’d respond by saying this past election shows that just isn’t true.
It’s true that advertising and subscription models aren’t great. But they aren’t great because they cater to the whims of the people. I don’t see where this proposal differs in that regard. Ultimately it still falls back to the people.
