Anytime there is a new technology that people do not understand, people immediately assume it can solve their problems too. It happened during the Atomic Age, and in the Space Age. This attitude is not to blamed because without it we will never be curious enough to adopt a new technique.
Blockchain can help track and transfer ownership of assets, ensure scarcity or uniqueness of digital information (like votes), and also store information in a way that cannot be altered ever. All of this comes at a price, the auditors of the network has to be paid in an asset managed on the same blockchain, and also everyone has to have a copy of all the information on the blockchain in a way that they too can view its content.
If any of these prerequisites are violated, the blockchain immediately becomes a very shitty database, and ordinary databases will be able to beat its features with ease.
