The future of the future is the same thing with Etherium Blockchain. Ether is simply one of its potential applications, so people can not use Ether as a direct payment method, but the major major revolutions given by etherium are so-called smart agreements and we have heard a lot about them in the future. Smart agreements, in fact, allow applications a huge potential.
Smart contracts, in fact, allow a huge possibility of applications. They are computer protocols that have the main purpose of executing the terms of a contract in order to satisfy common contractual conditions without the need of trusted intermediaries.
This way, smart contracts can be used as the deepest layer of any kind of application development and not just to set payment-related transactions.
