If you can take the word "cryptocurrency" and replace it with the word "database" in any article, then it's all bullshit.

A blockchain network is a distributed network that exists on all devices participating and is self-sustainable without a center point to record and manage data.

Imagine a library - in the library is the librarian who allows you to check out books. She uses her computer to collect data and record all transaction. This is the same principal that banks use, and the same idea that this article uses. This is considered a centralized network.
