The Internet of Things (IoT) suffer from lack of interoperability as data, devices, and whole sub-systems are locked in ‘silos’ because of technical, but mostly business reasons. Many new applications would be enabled and existing ones could be implemented in a more cost-efficient way, if the ‘silos’ could be bridged in a secure and privacy preserving manner. The SOFIE approach provides an effective way of accomplishing this by using interledger technologies that leverage the distributed trust enabled by distributed ledgers. The federated approach of SOFIE facilitates the creation of cross-organisational applications. This chapter presents the SOFIE approach and details the benefits it provides in four real-world pilots.
