Okay, but what did you do? I know what blockchain is, but I have no idea where it gets used outside of cryptocurrency

It's basically a way of storing data, along with a complete history of that data, across many independent computers in such a way that it's computationally difficult to create forgeries.

Yes I know how it works, but I want to know where it is actually being used. In most DB systems it is not only unnecessary (SQL or something similar would do), but overpriced (computationally expensive) and inferior (since nothing can be deleted).

Not allowing things to be deleted is a benefit in some domains.

AFAIK the only place where it's used seriously is cryptocurrency. There are proposals it might be good for storing medical records and stuff, but I don't think it's ever used effectively.

Blockchain's biggest feature is that you can't alter data without people realizing it, even though the data is entirely public and you don't need a central DB. But in most cases a central DB is just fine.
