What exactly are blockchains being used for in the real world?

Specific to this story: most of the world has instant payments without using blockchains or stablecoins, it’s only the U.S. where the banking system somehow hasn’t realised they can do instant payments using traditional banking technology.

Anyone posting that they’re skeptical about the use cases for blockchains on HN 10 years ago will have the same skepticism now. Nothing has changed.
