IoT (of the English, Internet of Things) is an extension of the current Internet, which provides any object, with computational ability of communication, to connect to the Internet. Through the connection to the worldwide network it is possible to remotely control the objects and allow them to be accessed as service providers. These new skills generate a great number of opportunities. According to a survey by consulting firm Gartner, in three years, 20 billion of things connected to the Internet. Another study, by McKinsey Global, estimates that the impact of IoT on the economy ranges from 4% to 11% of the planet's gross domestic product at 2025.
As one of the most digitized, the electric sector is also the most conducive environment for the development of Internet applications of Things. The benefits of IoT for energy consumers are diverse. In a simple instance, reclosers can, for example, communicate with each other and isolate the stretch of the problem and thus re-establish delivery to a larger number of customers and in the shortest time possible. IoT can leverage the results of analytical models to prevent technical failures, create intelligent sensor illumination systems, provide connections for measurement, among many others.
However, according to experts, IoT poses security, privacy and connectivity challenges. While so many benefits have also been associated with major cyber attacks, often involving devices, blockchain technology has emerged with the promise of reducing the risk of compromising IoT devices through a central one, and improving the scalability of implementations.
