I think the blockchain is not overvalued. It's fast and safe. Decentralization makes it possible to do many things, which it was impossible to do before.
I agree with you. Now the blockchain begins to be used in many areas, even government. Ensuring the safety of data acquisition and transmission is a good prospect.
The whole idea of Bonafi is built precisely on the blockchain. So I dont understand how you imagine this to be realized without the block chain. Many projects have already been attempted but nothing good happened.
