Can you please explain a bit more on this. Why do you think blockchain is hyped? Also did anything similar to blockchain (distributed decentralized information store) exist earlier?
Yes, sure. The bitcoin innovation was solving the duplicate transaction (or spend) problem in a trustless network. In a private blockchain you have trust between the nodes so this innovation does not apply.

Yes, databases supported this configuration before and the idea of smart contracts predates Bitcoin. Also, there are a lot of articles before Bitcoin about secure transaction logs.
