Implementing Decentralized Identity (DID) frameworks is a best practice for achieving secure and privacy-preserving user authentication in blockchain systems. DID frameworks empower users with self-sovereign identities, allowing them to manage and control their credentials without relying on centralized authorities. This approach enhances privacy by minimizing the exposure of personal information during authentication processes. For instance, the paper “Decentralized Identity Authentication with Auditability and Privacy” proposes DID authentication protocols that provide users with complete logs of authentication events, ensuring auditability, while preventing the linking of authentication events to specific users or service providers, thereby preserving privacy. By adopting DID frameworks, blockchain platforms can enhance security and user autonomy, aligning with contemporary standards for digital identity management.
