Another direction is to use the blockchain technology to achieve a trust, secure and incentive IoT. However, most of those solutions are based on the assumption of a stable and well connected underlying network, which is often luxury in mobile and dynamic IoT scenarios.
In this paper, we describe a new approach that combines the advantages of SCN and blockchain to empower IoT. We propose a service-centric blockchain architecture, which leverages a service-driven communication paradigm to support mobility and scalability.
We design a new consensus mechanism and en efficient ledger structure to provide trust, security and incentive in a decentralized manner. Finally, we develop a service pricing and distribution mechanism that fairly protects the profits of both service providers and users of the network.
