The "Experimentation: Smart Contract-based Digital Twins for the IoT" (SCDT) project will assess the feasibility and evaluate the performance of a novel form of decentralized, transparent, auditable, interoperable, and secure digital twins for Internet of Things (IoT) devices, such as sensors and actuators. The IoT is envisioned to be an ecosystem of interconnected devices merging the cyber with the physical world, to provide a multitude of services. The IoT has been on the spotlight of many research efforts in the past few years, and it has already been used in a variety of use cases, such as smart cities, smart homes, healthcare, etc. However, there are still some IoT challenges that need to be addressed. First, IoT systems are fragmented, since there is a plethora of IoT devices from different manufacturers, using different protocols and standards. Second, securing IoT services requires complex security solutions, usually relying on advanced cryptographic techniques and algorithms, which have not been designed for the IoT, where many devices are limited in processing, memory and energy resources. We argue that digital twins, with the right design, can address both these challenges, enhancing the interoperability, auditability, and security of IoT systems.
