The Economy of Things (EoT) is the evolution of the Internet of Things (IoT), where connected devices exchange not just information but also value. Examples of this include health trackers, smart appliances, electric vehicles, and private charging stations. Blockchains are often used as the digital backbone, providing a transaction layer and a machine identity service to enable interactions between devices from multiple ecosystems. Companies need to start adapting to the EoT in order to benefit from its advantages and mitigate its challenges.
