Decentralized Identity (DID) is fundamentally changing how personal identities are managed online by shifting the control of identity from central authorities (like governments and corporations) to individuals. DIDs are a type of digital identifier that utilize blockchain technology to ensure secure, private, and verifiable identities without relying on a central registration authority. Users can create their own DIDs and link them to various digital credentials (like qualifications or memberships) which they control. This not only improves security and privacy but also empowers users to selectively share information without exposing their entire identity.
