Cybersecurity and Traceability in Factory 4.0 highlights the challenges associated with the digitalization of production sites. While new digital technologies bring productivity gains, this transformation also brings new risks, constraints, dependencies and costs. However, there are practical approaches that enable manufacturers to navigate this transition in a way that is overall beneficial to their business.

Using the specific example of blockchain, one of the key components of Industry 4.0, this book illustrates its specific application in implementing traceability to build trust between the factory, its suppliers and its customers, while preserving the confidentiality of the third parties involved. It demonstrates that the energy and storage costs often associated with blockchain are not inherent to the technology itself, but result from implementation choices. Concrete and practical approaches, as well as evaluation tools, are proposed to facilitate the integration of blockchain into an operational factory.
