Blockchain is a potentially important technology that enables a shared data infrastructure, and is well worth investigating. Hence the interest in this book.As a result, there are many opportunities for decision-makers to use this work as an introductory point to a distributed future powered by Blockchain. This work can also serve as a starting point for further research, particularly in the Tunisian healthcare system, which is undergoing structural and organizational transformation today. The healthcare ecosystem is seeing the emergence of a networked structure whose digital urbanization is expanding, and whose mastery of information management is bringing with it economic and legal challenges, as well as real prospects for the information professions.
