Diving into the digital frontier, the Sustainable and Interoperable Digital Identity (SIDI) Hub, an alliance of 17 open-standard organizations, is striving to create cross-border digital identities.

However, recognizing the diverse perspectives globally, they also highlight the need for taking into account the unique social, cultural, and legal contexts of each nation.
