Exploiting the IoT Potential of Blockchain in the IEEE P1931.1 ROOF Standard

While initially conceived as a system for cryptocurrency transactions' validation among untrusted parties, blockchain technology has gained momentum as a tool that can theoretically be applied to many domains beyond the intended one. Among these domains, one of the biggest and most promising is the Internet of Things. The IEEE 1931.1 WG is currently working on the definition of an Internet standard for technical and functional interoperability of federated IoT systems for Real-Time Onsite Operations Facilitation (ROOF) that operate and function in a secure, semi-autonomous, and decentralized manner. Blockchain technology can play a key role in accomplishing this goal. In this article, after discussing the use of blockchain technology in the IoT, the architectural framework as well as the use of blockchain technology in the IEEE 1931.1 standard are discussed in terms of advantages brought, criticalities, and future improvements that are necessary for fruitful deployment within ROOF.
