**7. Conclusions**

The Blockchain is a distributed database or public ledger that stores a list of all digital events or transactions that have occurred and is fundamentally shared among all participants. Blockchain technology is perfect for securing, sharing, and verifying learning achievements as a new infrastructure. In the case of certificates, a Blockchain can maintain a list of the certificate's issuer and receiver, as well as the document signature (hash), in a public database (the Blockchain) that is replicated on thousands of computers all over the world.

Regarding the case study presented, it can be seen that all five hypotheses are validated. Thus, it can be said that the first link is between the use of Blockchain technologies in the education sector and the need for Blockchain knowledge in different professions. A second link is between the issues to be considered before including Blockchain technologies in the education sector and the use of Blockchain technologies. The third link is the knowledge of Blockchain technologies in different professions and the benefits of adopting Blockchain technologies. The fourth link is between the issues to be considered before including Blockchain technologies in the education sector and the benefits of adopting Blockchain technologies, but also a link between these issues and the challenges of adopting Blockchain technologies in the fifth hypothesis. Thus, the different subpoints that constitute the elements of the hypothesis are influenced by the existence of different reasonable correlations, but also weaker correlations.
