In today’s digital world, identity is controlled by centralized platforms such as social media companies, banks, and governments. Every time users log in, share personal data, or verify themselves, they rely on third parties to manage and store their information. This creates risks related to data breaches, privacy loss, and lack of user control. Decentralized Identity (DID) is emerging as a solution to this problem by allowing individuals to own and manage their digital identities using blockchain technology.
