What are the benefits of blockchain technology that currently aren't solved by having some central trustworthy source maintain a database?
To me it seems that a "blockchain" claim to fame is being decentralized. But who maintains the tech to make the system reliable? Seems like a centralized organization would essentially be needed to maintain a database used by others.
It's about trust, you either trust some central solitary authority, i.e. government, bank, etc... or you trust the majority of users -- to do the right thing.
Think of it like a dictatorship vs a democracy. In the dictatorship one guy ( the central authority ) gets to make the rules... he has a bad day? he decides to take all your wealth for himself. In the democracy 51% of nodes have to decide to screw you, some people think that's a better bet in the long run.
