Self-Sovereign Identity
Self-Sovereign Identity (SSI) is a digital identity model where individuals or entities have full ownership and control over their identity data, without relying on centralized authorities. It enables users to create, manage, and share verifiable credentials (e.g., digital IDs, certificates) directly with others using decentralized technologies like blockchain. This approach enhances privacy, security, and interoperability in identity management across various domains such as finance, healthcare, and government services.
Developers should learn SSI to build privacy-preserving applications that comply with regulations like GDPR, as it reduces data breaches by eliminating centralized identity repositories. It is crucial for implementing decentralized authentication systems, verifiable credentials for digital onboarding, and trust frameworks in Web3, IoT, and cross-border identity solutions. SSI skills are valuable in industries requiring secure, user-centric identity verification, such as fintech, e-government, and healthcare.
