What is a VC (Verifiable Credential)?

A Verifiable Credential (VC) is a digital, cryptographically-secured document that proves certain attributes or qualifications of a person or entity, issued by a trusted issuer and independently verifiable by any relying party.

Key aspects of Verifiable Credentials include:

• Issuer: The trusted authority or organization (e.g., government, university) that issues the VC.
• Holder: The individual or entity who possesses and controls the VC.
• Verifier: A third-party who independently verifies the authenticity of the VC.
• Cryptographic Security: VCs use digital signatures and cryptographic proofs, ensuring authenticity, integrity, and tamper-proof attributes.

Common use-cases for VCs include digital identity cards, professional certifications, educational qualifications, and licenses. They significantly enhance security, trustworthiness, and interoperability across digital identity ecosystems.

A Verifiable Credential (VC) represents digitally verifiable claims about an individual or entity. Unlike traditional digital documents or certificates, VCs incorporate robust cryptographic mechanisms, enabling seamless verification without the need to contact the original issuer.

Verifiable Credentials are based on modern cryptographic standards and decentralized identity concepts, typically involving:

• Decentralized Identifiers (DIDs): These are globally unique identifiers that enable VCs to be linked securely to the holder without centralized authority.
• Cryptographic Signatures: VCs are digitally signed by issuers, providing cryptographic proof of authenticity and integrity.
• Privacy and Selective Disclosure: Holders can choose to share only necessary details of a VC, enhancing user privacy and control.

Verifiable Credentials are increasingly prominent in various sectors:

• Education: Digital diplomas and certificates issued by universities, instantly verifiable by employers worldwide.
• Healthcare: Secure digital vaccination certificates, ensuring authenticity and easy international recognition.
• Government Services: Digital driver’s licenses and national IDs, simplifying identification processes while ensuring privacy and security.
• Employment and Professional Certifications: Digital credentials for professional licenses and skills verification, streamlining hiring processes.

VCs offer substantial benefits to users, issuers, and verifiers:

• Enhanced Security: Tamper-proof cryptographic signatures eliminate fraud and forgery risks.
• Improved Privacy: Users have control over their data, deciding precisely what to share and with whom.
• Efficiency and Cost Savings: Streamlined verification processes significantly reduce administrative overhead and associated costs.
• Interoperability: Standardized digital credentials that can be easily recognized and verified across borders and sectors.

Verifiable Credentials are standardized by the W3C (World Wide Web Consortium), ensuring global interoperability and consistency. Major global tech companies, governments, and institutions are actively adopting and implementing this standard, fostering an ecosystem of trusted digital identities.

By embracing VCs, organizations and users can confidently operate in digital environments, significantly enhancing security, trust, and efficiency.

A Verifiable Credential (VC) is used to digitally verify specific attributes about individuals or entities, such as identity, qualifications, or licenses, securely and reliably.

VCs are issued by trusted authorities or organizations, including governments, educational institutions, healthcare providers, and professional bodies.

Yes, VCs use robust cryptographic signatures and decentralized identifiers, making them secure, tamper-proof, and reliably verifiable.

Verification involves cryptographically checking the issuer’s signature and ensuring the credential hasn’t been altered. This can be done independently without contacting the original issuer.

Yes, VCs support selective disclosure, meaning users can share only the specific information needed, preserving their privacy and control over their personal data.
