Blockchain, or cryptocurrency? Be aware, those are not the same technologies. Blockchain is working fine on its own. There are some projects and usages which are predating the cryptocurrency-terms. The versioning-system git might be the most well known project with this bubble here. But it's also disputed how blockchainy git is. So to name something else, the smart home standard Matter is using a blockchain for managing their certifications or legitimated devices, something like that. With cryptocurrency on the other side, the most "legit" usage case I've seen so far, is hybrid-NFTs, from DC Tracing Cards. Where you get physical cards, and an NFT alongside it. Not sure how successful or scammy this is, but considering trading cards are an established semi-legit business, I would say this kinda counts as real world.
