Blockchain + version control for news?
Assuming your comment was sincere, I'll engage with your content instead of downvoting:
1. You don't need a distributed, P2P database to archive news. Archive.org already does it, for example. So do some libraries.
2. Saving things in immutable, distributed databases does not require a blockchain. BitTorrent has been mostly successful at this for decades, for example.
3. It's common for stories like this to be covered in thousands of reputable and unreputable publications. The reputable ones already have policies against changing old stories, though none seem to do routinely change stories in practice. Either way, to update a story like this, you only need one example of the coverage.
Didn't have a clear idea of what the implementation details would have to be so I just named the two closest concepts that came to mind.
At this point, the word blockchain itself is very stigmatized. It doesn't help that a lot of the pro-blockchain social media world (reddit, Twitter, and Instagram) is populated by nutjobs and scammers.
Side note: I recommend you think of downvotes as "this isn't the most informative comment and should be lower" rather than "I hate you as a person". It's almost always the former rather than the latter. The latter is usually flagged instead of downvoted.
To be quite blunt, this is a recipe for downvotable comments.
But I do somewhat agree with sentiment of having immutable news archive as the present Internet is more 'what we can see' oppose to 'what we can know'.
