  Industrial Internet of Things is a new milestone that will require new
industry paradigms and investments. In this context, cyber-physical systems are
considered the bridge to the fourth revolution. Centralized approaches and
observance of real-time constraints are two important challenges that must be
overcome for the advancement of Industry 4.0. To solve these problems, a
blockchain-based vertical integration architecture of the process automation
systems is proposed in which it performs the control and monitoring of
industrial processes. Proof of concept experiments reveal the feasibility and
performance of the proposal.
