Question 1

What are Self-Sovereign Identity solutions?

Accepted Answer

Self-Sovereign Identity solutions are decentralized digital identity systems that allow individuals or organizations to control and manage their own identity information. They typically use digital wallets, decentralized identifiers, verifiable credentials, and cryptographic verification to enable trusted identity sharing without relying entirely on centralized authorities.

Question 2

How does Self-Sovereign Identity work on blockchain?

Accepted Answer

Blockchain can provide trust infrastructure for SSI by recording decentralized identifiers, public keys, credential schemas, or revocation information. Personal data does not usually need to be stored directly on-chain. Instead, users hold credentials in secure wallets and present cryptographic proofs that verifiers can validate.

Question 3

What are the benefits of Self-Sovereign Identity?

Accepted Answer

Key benefits include greater user control, improved privacy, portable credentials, reduced repetitive verification, lower dependence on centralized databases, and enhanced data security. SSI can also support more efficient KYC, digital onboarding, professional verification, healthcare access, and government services.

Question 4

Is Self-Sovereign Identity secure?

Accepted Answer

SSI can provide strong security through cryptographic signatures, decentralized identifiers, selective disclosure, and verifiable credentials. However, security also depends on wallet protection, private-key management, recovery procedures, software quality, and user awareness. Lost credentials or compromised keys can create serious risks if recovery systems are not properly designed.

Question 5

What industries can use Self-Sovereign Identity?

Accepted Answer

SSI can be used in finance, healthcare, education, government, employment, travel, insurance, telecommunications, supply chains, and online services. Any industry that needs reliable identity verification, trusted credentials, privacy-preserving authentication, or reusable compliance data may benefit from decentralized identity solutions.
