I’ve also got a charactersheet on D&D Beyond and some PDFs from DrivethruRPG, all digital. Not that I’m going to get in to the Glimmering but if others want to, more power to them…
A character sheet on D&D Beyond contains actual data. At present, the vast majority of NFTs, whatever they may be, do not contain data, but rather, URLs or other things which point
to data. There are exceptions, but they are just that, exceptions.
Every PDF you have purchased from DrivethruRPG is, like the previous, actual data
. If DrivethruRPG were to go under, you might not be able to get that data back, but you do, in fact, actually have
that data. With NFTs, the one (and only) thing you "own" is, effectively, an ID number which contains a very, very small data file. That very small data file generally contains a set of text, such as a URL, which points to something else.
NFTs are scammy as hell because, in general, they sell themselves as actual
ownership of something--an artwork, a data file, a piece of music, what-have-you--but in truth the NFT you buy isn't even a certificate by itself. It's just a chunk of code, which has a URL inside it. If that URL expires, or gets changed, you're screwed. If someone else finds that URL and shares it, you most certainly don't have the ability to stop them from doing so. And if someone takes the data, such as a piece of art, and uses it in ways you don't like, you absolutely do not
have any kind of rights regarding the work, even if the work is something like commissioned art.
Like the vast majority of artificial scarcity technology, it's a quirky and idiosyncratic idea in search of a use-case, not a revolutionary change in human existence that the normies
are too stupid to adopt. That doesn't mean that artificial scarcity cannot ever have a use case. But you should be as suspicious of any proposed use as you would of snake oil, especially
if someone is making grand, society-transforming or fortune-making promises.
It is likely that some kind of real, practical, meaningful application for blockchains will exist someday. It may even be the case that in certain niche ways, NFTs could be useful (perhaps as a credentialing system, or a way to cut down on paperwork by automating certain kinds of bookkeeping.) But in the vast majority of cases, artificial scarcity tech is a solution desperately hunting for a problem.
