A blockchain is just a type of data structure. Cryptocurrencies use blockchains, but mining, trustless distributed consensus, fault tolerance, and all these other things are features of cryptocurrency implementations, not essential elements of blockchains.
Volkswagen quite publicly use that very solution from IBM, and there’s numerous other examples of it being used in supply chain management, which absolutely isn’t the only useful application of blockchains.
It’s not even clear if you know what a blockchain is, and your comments on its usefulness are just as extreme and misinformed as the evangelists who say it can be used to solve any problem under the sun.
Link me to the VW thing please? Last I checked there was literally no reason to use blockchain outside of cryptocurrencies since you get the same benefits just using GIT.
Looks like they want to use it to lower traditional auditing costs in developing countries. Not sure how the blockchain tech is supposed to help tracking materials or establish trust in such an environment but that's not really my field - presumably it adds a component of different people creating a digital paper trail that's harder to manipulate. That's an application compliance people in a few sectors seem to like these days, guess we'll see if it actually makes sense over traditional efforts in N years.

How does the data structure of a git repo differ from a blockchain? The only difference I can see is in how it’s used. A blockchain wouldn’t have more than one permanent branch.
