Towards a Methodological Approach for the Definition of a Blockchain Network for Industry 4.0

The Industrial Internet of Things is expected to attract significant investments for Industry 4.0. In this new environment, blockchain has immediate potential in industrial applications, providing immutable, traceable and auditable communication. Blockchain gained prominence in the academy, being developed and evaluated in several application areas. However, no study has presented methodologies to definition blockchain networks in the industrial environment. To fill this gap, we present a methodology that presents paths to follow and important aspects to be analyzed for the definition and deployment of a blockchain network architecture. This methodology can help in the appropriate choice of platforms and parameters of blockchain networks, resulting in a reduction of costs for the factory and safety in meeting deadlines for industrial processes.
