Give me an example of using a blocking business. And what is the use of blockchain in potentiam?
In the first place - is the preservation of copyright, any valuable information. And secondly - safe and cheap money transfers.
In general, in business, an excellent example - currency registers (currency ledgers) based on the blockchain system eliminate the need for banking institutions. They not only connect users of the network, but also provide a platform on which you can trust accounts and transactions associated with them without the need to monitor the central authority.
