Integration of IoT Equipment as Transactional Endorsing Peers over a Hyperledger-Fabric Blockchain Network: Feasibility Study

Internet of Things (IoT) experiences exponential growth in research and industry fields; the usefulness provided by IoT extends from critical applications such as intelligent transport systems and e-health to business-related applications such as banking and logistics. At the same time, faces privacy and security vulnerabilities becoming target of cyber-attacks, being necessary to mitigate them. Conventional security and privacy approaches tend not to be applicable for IoT, due to its decentralized topology and limited resources on its devices. Blockchain appears as a possible solution to the intrinsic security deficiency in IoT environments, since it has demonstrated its applicability in security and privacy fields over end-to-end networks with similar topologies as the ones used in IoT, thanks to its Defense-in-Depth approach is ideal for critical environments.
