In simple terms, a blockchainblockchain is an exchange of something between two parties without a middleman, but that transaction has been verified and witnessed by others to avoid corruption. The goal is to remove the middleman since he is to be trusted with power in the matter of the exchange.

Traditionally, there is always a middleman who controls the data. As an example, FacebookFacebook is the middleman between users and advertising companies that buy your data for selling points in good advertising. Another way to look at it is banks between barrows and lenders. Even if Western UnionWestern Union is sending or receiving money, they have the power to collect, stop, or report your money.
