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 studies
here but none of them stand out. I guess nobody has made the "OpenAI of blockchains" yet, because I have yet to see any large application of blockchain outside of crypto.
In fact, there's a veritable graveyard of technologies that tools providers like Amazon and IBM have offered over the years since they are completely hype-driven, only for those technologies to never get past the tire-kicking phase. The tools industry is worth billions and they have little downside in adopting whatever buzzword that comes along even if it's never adopted for a real project with real ROI. In the same vein, big companies like Citibank will allow their CIO's to say things like, "blockchain is cool" but never actually implement anything using it.
Hence I'm bypassing all of the companies who are "excited about blockchain" and instead focused on the application that checks all of the boxes I listed above. Tell me what you can build with blockchain that you can't build without it--and what the real-world benefit to the consumer is, in terms of hard numbers.
This is how you separate a technology that's going to fall by the wayside and one that will stick around for the long haul...
