Verifiable Credentials: Simple Guide and Use Cases

What are Verifiable Credentials?

Verifiable credentials are like digital versions of your ID cards, certificates, or licenses. They are secure, easy to share, and hard to fake. Think of them as digital badges that prove something about you is true.

Why Are They Important?

Verifiable credentials make it easy to prove your identity or qualifications without the need for physical documents. They are safe and can be trusted because they are stored in a secure way that ensures they can't be tampered with.

How Do They Work?

1. Issuance: An organization (like a university or employer) gives you a verifiable credential.
2. Storage: You store this credential in a digital wallet on your phone or computer.
3. Sharing: When you need to prove something (like your degree or work experience), you share the credential from your wallet.
4. Verification: The person or organization you share it with can check that the credential is real and hasn't been altered.
