From logging into apps and accessing banking services to verifying credentials and making online purchases, identity systems play a crucial role in everyday life. However, traditional digital identity models are increasingly facing challenges related to security, privacy, and control.<\/p>\n<p>Blockchain technology is emerging as a transformative solution, offering a decentralized, secure, and user-centric approach to identity management.
