Decentralized Identity
Decentralized Identity (DID) is a digital identity framework that enables individuals and organizations to own and control their identity data without relying on centralized authorities like governments or corporations. It uses decentralized technologies such as blockchain and cryptographic protocols to create self-sovereign identities that are portable, verifiable, and secure. This approach aims to enhance privacy, reduce identity fraud, and give users full autonomy over their personal information.
Developers should learn Decentralized Identity when building applications that require secure, privacy-preserving identity management, such as in finance, healthcare, or supply chain systems where user data sovereignty is critical. It is particularly useful for implementing self-sovereign identity solutions, enabling verifiable credentials, and reducing dependency on third-party identity providers. Use cases include decentralized authentication, digital wallets, and compliance with regulations like GDPR by minimizing data collection.
