Abstract—Connecting hundreds of billions of devices, the
Internet of Things (IoT) has become a technology with large
influence in people’s life. However, the future of IoT is threatened
by frail connectivity, poor scalability, absent trust, cracked
security and broken business model. Researchers have proposed
Service-centric Networking (SCN) to provide reliable connectivity
and global scalability, while the trust, security and incentive
of services in such approaches are hard to be guaranteed.
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
