So I’m clear, does blockchain always refer to those *coin currencies? Or is it be used for other purposes too?

Imagine you have a database, you decide to add something to it and now you have to solve 5000 sudokus. Also you can't remove anything as well. Have fun

Imagine many entities have a shared database. You cannot trust anyone else but you have to add something. The consensus mechanism of the algorithm of your choice ensures that only good actors participate through sheer game theory. This naturally has a cost and you are happy to pay it. You have a lot of fun

Thank you for this. I’ve grown too tired of explaining it after the last 15 years.

Just because it’s not the solution for everything doesn’t mean it’s not a solution for something. Blockchain revolutionized global finance.
