🔎 What are verifiable credentials?

Verifiable credentials are digital records containing claims that are issued and cryptographically signed by a trusted organization or individual. A recipient can store the credential and present it to another party, which can verify its authenticity without contacting the issuer every time.

⛓️ How does blockchain support verifiable credentials?

Blockchain can provide a trusted infrastructure for checking issuer information, decentralized identifiers, credential status, and revocation data. Sensitive personal information should generally remain off-chain, while the blockchain stores proofs or references that help confirm validity.

🛡️ Are blockchain-based credentials private?

They can be designed to provide strong privacy through selective disclosure, encryption, and zero-knowledge proofs. Privacy depends on the system’s architecture, wallet security, governance, and the amount of information recorded on-chain. A well-designed solution minimizes unnecessary data exposure.

🏢 Where are verifiable credentials used?

Common use cases include digital identity verification, education certificates, employee credentials, professional licenses, healthcare records, reusable KYC, travel documents, supply chain claims, and secure access management. Their portability makes them useful across multiple organizations and platforms.

🔐 What are the main challenges of blockchain digital identity?

Key challenges include interoperability, regulatory compliance, user experience, private-key recovery, credential revocation, identity governance, adoption, and integration with legacy systems. Building trustworthy identity ecosystems requires cooperation between technology providers, governments, businesses, standards organizations, and end users.
