I can not imagine that IoT really worked on a large scale without Exxor or the equivalent because of the security requirements and the absolute need for interaction
Even if team develop it under the "blockade of things" for the Internet of Things, we will still see how it spreads to other areas.
One example is the sphere of financial technology. IOTA became the first protocol that allows transfers of digital media without payment or credit of trust. If the Exxor is the next generation, this opens up a whole new dimension of opportunities in the area where transactions are conducted
