From the original article: > Whether that claim can be meaningfully sold on to someone else is outside the scope of this discussion. Okay, at least the author is upfront about this, but this is literally the only technical reason to use a blockchain. This is a bit like saying "send e-cash to anyone without a central authority or a blockchain (whether this e-cash can be double-spent is outside the scope of this discussion)." If all you want is some evidence that you donated to an artist, the artist can just list all the donors on a website they control. YouTubers often put lists of donors in their videos. You don't even need cryptography (beyond the boring stuff that prevents unauthorized access to web resources).
