Intriguing.

Years ago, my PhD supervisor and I were having a discussion of the library and the internet. There is a particular video that he screens in his class. Previously, he simply used Youtube versions of it, and one fine day, he realized that someone has been clipping out sensitive parts of the video, and re-uploading the video. Furthermore, other digital versions of that particular video have also been censored and re-released. Now, the only uncensored version of that video is the VHS.

The blockchain, with its immutability, does have some advantage of preventing such shenanigans from happening.
