Query: How BlockChain Can Help Enhance The Security And Privacy in Edge
  Computing?   In order to solve security and privacy issues of centralized cloud services,
the edge computing network is introduced, where computing and storage resources
are distributed to the edge of the network. However, native edge computing is
subject to the limited performance of edge devices, which causes challenges in
data authorization, data encryption, user privacy, and other fields. Blockchain
is currently the hottest technology for distributed networks. It solves the
consistent issue of distributed data and is used in many areas, such as
cryptocurrency, smart grid, and the Internet of Things.
  Our work discussed the security and privacy challenges of edge computing
networks. From the perspectives of data authorization, encryption, and user
privacy, we analyze the solutions brought by blockchain technology to edge
computing networks. In this work, we deeply present the benefits from the
integration of the edge computing network and blockchain technology, which
effectively controls the data authorization and data encryption of the edge
network and enhances the architecture's scalability under the premise of
ensuring security and privacy. Finally, we investigate challenges on storage,
workload, and latency for future research in this field.
