Query: Blockchain and Fog Computing for Cyberphysical Systems: The Case of
  Smart Industry   Blockchain has revolutionized how transactions are conducted by ensuring
secure and auditable peer-to-peer coordination. This is due to both the
development of decentralization, and the promotion of trust among peers.
Blockchain and fog computing are currently being evaluated as potential support
for software and a wide spectrum of applications, ranging from banking
practices and digital transactions to cyber-physical systems. These systems are
designed to work in highly complex, sometimes even adversarial, environments,
and to synchronize heterogeneous machines and manufacturing facilities in cyber
computational space, and address critical challenges such as computational
complexity, security, trust, and data management. Coupling blockchain with fog
computing technologies has the potential to identify and overcome these issues.
Thus, this paper presents the knowledge of blockchain and fog computing
required to improve cyber-physical systems in terms of quality-of-service, data
storage, computing and security.
