What It Is (And Isn’t)

A digital credential is a certified piece of information that proves something about you, like your name, age, or that you graduated from school. It's not just a digital copy (like a photo or PDF). It's a secure, verified, and tamper-resistant record that lives in a special app on your device called a digital wallet.

Each credential is like a leaf that was grown by a trusted tree (like your university or DMV) and handed to you to keep in your pouch (your wallet). They “sign” the leaf using something called cryptography, which seals it so others can trust it's real.

Why It’s Better Than Paper

Paper documents can be lost, copied, or faked. Digital credentials:

• Use cryptography (math!) to prove they haven’t been changed
• Can be checked instantly without calling anyone
• Let you share only what’s needed (like proving your age without showing your birthdate)

They're also:

• Easier to carry (on your phone)
• Harder to forge
• Faster and more convenient to use in everyday situations

Where Do You Use Them?

Digital credentials are already being used in:

• Airports: Show your mobile ID to get through security
• Concerts: Scan your digital ticket
• Hospitals: Share vaccination or health info
• Schools and jobs: Prove qualifications or degrees

Each of these interactions is like showing a leaf in the digital forest that glows with trusted proof. You don’t have to wait or ask for help, you’re in control.

How Credentials Are Issued

A trusted organization, like a school, government, or employer, creates and signs the digital credential before handing it to you. This is called issuance. Think of them as the original tree, growing a new leaf with your name on it and gently placing it into your digital wallet.

The issuing tree uses special cryptographic tools to imprint a unique digital signature on your leaf. That signature is proof that the leaf is real and hasn’t been changed.

How Verification Works

When someone wants to check your credential, like a bartender checking your age or an airport checking your ID, they’re acting as a verifier.

They don’t need to call the issuing tree. They simply scan your leaf and check the digital signature. If it glows true (meaning the cryptographic proof is valid), they know it’s real.
