Think of the Blockchain as an online database or a virtual ledger of some sort, with the technology it has given it has simply removed the use of third party services as you only need your cryptocurrency wallet in order to send and receive from the other party you are dealing with, it simply has removed the used of banks for their bank transfers which includes a more expensive fee compared to what network fees you are paying today.

Now imagine using that kind of technology on other day to day transactions from buying and selling of assets (real estate, stocks) to the government's activities it will give you more transparency on your deals and their actions. Someone will input/execute the transaction and everybody can look it up in the blockchain. Just think of it as an tamper proof online ledger where once you successfully inputted a data it can never be change or altered inside the chain. The positive benefit I see is that this tool will be a cost-effective way of reducing the potential frauds happening in our transactions.
