A Decentralized Identifier (DID) is a new type of identifier that enables individuals and organizations to create and manage their own unique identifiers without relying on a central authority. DIDs are designed to provide users with more control over their digital identities.Unlike traditional identifiers, such as email addresses or usernames linked to a central service, DIDs are stored on a blockchain or similar distributed ledger. This decentralization enhances privacy and security by reducing the risk of data breaches or unauthorized access.DIDs can be linked to various kinds of verifiable credentials, such as education certificates or professional licenses, allowing users to selectively share information. This functionality supports a self-sovereign identity model, giving users the ability to prove their identity or qualifications without revealing unnecessary personal details.Ultimately, DIDs empower users by granting them greater autonomy and flexibility in managing their online presence, fostering trust and privacy in digital interactions.
