  Blockchain is gaining momentum as a promising technology for many application
domains, one of them being the Edge-of- Things (EoT) that is enabled by the
integration of edge computing and the Internet-of-Things (IoT). Particularly,
the amalgamation of blockchain and EoT leads to a new paradigm, called
blockchain enabled EoT (BEoT) that is crucial for enabling future low-latency
and high-security services and applications. This article envisions a novel
BEoT architecture for supporting industrial applications under the management
of blockchain at the network edge in a wide range of IoT use cases such as
smart home, smart healthcare, smart grid, and smart transportation. The
potentials of BEoT in providing security services are also explored, including
access authentication, data privacy preservation, attack detection, and trust
management. Finally, we point out some key research challenges and future
directions in this emerging area.
