No, no, no! That's the whole reason behind why it sucks... you can't trust it! You have to verify every record on that chain by yourself, and if you make a mistake in a transaction or other operation there is no court or process that can give you restitution. Its also very inefficient (massively slow) compared to a distributed database, while functionally doing the same thing. There are barely any use cases where you don't want central authority and you want distributed storage... centralized databases are always going to be more efficient and convenient. If you want to use a inefficient, crappy excuse for a database be my guest.
