Digital Identity

Definition ∞ Digital identity refers to the unique set of attributes and credentials that represent an individual or entity in the digital realm. In the context of blockchain and cryptocurrencies, this can involve self-sovereign identity solutions where users control their personal data, or pseudonymous on-chain identifiers linked to wallet addresses. It is the representation of an entity within digital systems.
Context ∞ Discussions on digital identity within the crypto space often revolve around privacy-preserving technologies, decentralized identifiers (DIDs), and verifiable credentials. The development of robust and secure digital identity frameworks is seen as crucial for enabling wider adoption of blockchain applications and ensuring compliance with KYC/AML regulations.
