Question 1

What is a decentralized identity management system?

Accepted Answer

A decentralized identity management system allows individuals or organizations to control and use digital identities without depending entirely on a single centralized identity provider. It typically uses blockchain networks, cryptographic keys, decentralized identifiers, and verifiable credentials to establish trust and verify information.

Question 2

How does decentralized identity differ from traditional digital identity?

Accepted Answer

Traditional digital identity systems often store and manage user information through a central authority or platform. Decentralized identity enables users to hold credentials in a digital wallet and share specific information directly with trusted services, supporting greater privacy, portability, and user control .

Question 3

What are decentralized identifiers and verifiable credentials?

Accepted Answer

A decentralized identifier is a cryptographically secured identifier that can be controlled without relying on a centralized registry. A verifiable credential is a digitally signed statement issued by a trusted entity, such as a university, employer, or government agency, that can be independently verified by another party.

Question 4

Is decentralized identity secure?

Accepted Answer

Decentralized identity can improve security by reducing centralized data storage, supporting cryptographic verification, and enabling selective disclosure. However, security depends on strong wallet protection, private-key management, reliable recovery processes, secure software, and responsible governance. Users must protect their credentials from phishing, malware, and unauthorized access.

Question 5

Where can decentralized identity be used?

Accepted Answer

Decentralized identity can be used for financial onboarding, healthcare verification, education credentials, employment records, travel documents, online authentication, professional licenses, supply chains, and government services. Its usefulness is especially strong wherever organizations need trustworthy verification while minimizing the exchange of sensitive personal data.
