    Not true. This is something I had researched in the early days. If you can store a crypto hash of the document on a Blockchain, you can upload said document anywhere you want for people to DL. The hashes will always match, and you can use the timestamp of the Blockchain entry as reference to veracity. This could be done via an open source project and should the maintainers fall off the map, some one can always fork.

    I remember seeing this listed as something like “proof of existence”.

      It just means the file existed at the time. I guess that’s useful to an extent. Maybe bodycams could upload hashes of 1 second segments of video & audio delay but it’s ± limited to that.
