IBM is such a shadow of what it used to be. Hopefully newer health+genomic+ai startups or initiatives at less dinosauresques companies will make the next leap happen in our lifetime.
I attended a talk a few years ago given by one of the blockchain VPs at IBM.
It turned out that under the hood they were just using conventional distributed database technology. All marketing in order to get multiple companies to work together on shared systems.
I agree when thinking about building software in one org where there is coordination. When expanding to multi org and international, the problems to solve become much clearer imo.
Federated, hashed data stores in zero-trust environments is one (though this isn't the best or only way to approach it, and blockchain is almost always unneeded), where you don't want to share the underlying data but want to provide enough information to support reporting requirements. Public health, taxation, etc. come to mind.
HyperLedger Fabric docs have an example of a manufacturer, vendor and short term finance provider all on the same network with transactions happening instantaneously. Then when you look into case studies, Honeywell has an airplane parts marketplace that’s apparently streamlined their sales process. I’ve seen some Upwork contractors demoing medical data platforms. I didn’t understand that one as much.
