Decentralized Identity

Definition ∞ Decentralized identity is a digital identity system where individuals control their own identity data without relying on a central provider. Users manage their credentials and choose what information to share, enhancing privacy and security. This approach shifts ownership of personal data from organizations to the individual.
Context ∞ The development of decentralized identity solutions is currently a significant area of focus, driven by increasing concerns over data privacy and security breaches. Discussions revolve around establishing robust standards for self-sovereign identity and ensuring widespread adoption. Key future developments include the integration of decentralized identifiers (DIDs) with verifiable credentials across various platforms and services.
