Most things that rely on decentralization are design wins because they depend on a similarly decentralized blockchain, like on top of Bitcoin, ETH. (So not something like a stablecoin or exchange.)
Nobody's able to shut down a sufficiently decentralized system. Mainly, this benefits financial applications like cryptocurrency. If you look around, you will find there is not much incentive for people to use blockchains to solve other types of problems.
I think what you are saying is that there's no use for blockchain outside of cryptocurrencies. Many people are
saying things to the contrary, but I am looking for a
specific example of a
real world solution.
If there was no use for blockchain outside of cryptocurrency, then Amazon would not have created Managed Blockchain and IBM wouldn't have made HyperLedger Fabric. Banks in particular like them, but these are just buzzwords and I don't know why they would be interested in such tech.
There are some case studied
here but none of them stand out. I guess nobody has made the "OpenAI of blockchains" yet.
