Identity Management

Definition ∞ Identity Management refers to the framework and processes used to control and verify the identity of individuals or entities within a digital system. In decentralized networks, this can involve self-sovereign identity solutions, decentralized identifiers (DIDs), and verifiable credentials. Effective identity management is crucial for security, compliance, and user experience in Web3 applications.
Context ∞ The development of robust Identity Management solutions is a critical area for the maturation of decentralized applications and the broader Web3 ecosystem. Discussions frequently address privacy concerns, the trade-offs between anonymity and accountability, and the technical challenges of achieving interoperable and secure identity verification. Regulatory compliance, particularly concerning Know Your Customer (KYC) principles, is a significant driver of innovation.
