**1. Introduction**

The emergence of new technologies of knowledge in all fields, their dissemination, and their application for social or economic benefit are essential activities for the progress of society worldwide. Its development has been essential for international economic and social convergence. However, the regulation and legal implications of these new technologies need to be addressed in the legal systems of every country. Therefore, in order to regulate the basic conditions that guarantee the equality and rights of individuals, legal systems should pay special attention to the legal challenges that new technologies can present. This includes, for example, blockchain technology in the future of contracts, big data, and the protection of personal data; the emergence of electric scooters as a new form of urban mobility; or even the fact that dependence on new technologies can affect one's personal life, where one seeks the right to disconnect digitally, and even the right to be forgotten.

This Special Issue aims to provide new legal advances in connection with new technologies. Therefore, research articles on any of these fields, with a global or local perspective, were welcomed.
