NFTs.

It's not a terribly interesting answer, but you've asked your question in an uninterested way.

Since there are a lot of good and bad, intrinsic and extrinsic reasons tech does and does not get adopted, I think a better question might be: "Without any BS or deceptive rationalization, what's something that blockchain really would be better at?"

Okay, NFTs, fair enough :)

They often run off the Ethereum ledger, am I right?

AFAIK that's entirely true, but as asked it's a non-cryptocurrency project.
