A paper titled “Secure Open Federation of IoT Platforms Through Interledger Technologies - The SOFIE Approach” was recently presented at the EuCNC 2019 conference. You can read the paper HERE
The paper details key problems arising from IoT interoperability and describes how SOFIE, through usage of distributed ledger technologies (DLTs), can both provide interoperability and improve the security and privacy of IoT platforms and services. The paper then describes two of the four SOFIE pilots in more detail: agricultural supply chain, where produce growth and transportation conditions are tracked from field to fork, and balancing of the electrical grid by offering incentives to EV owners to charge their cars at certain times and locations. Finally, the paper also discusses how SOFIE enables the creation of new business models and open data markets in the future.
