Decentralized Identity (DID) & Verifiable Credential (VC) Explorer

An interactive playground for exploring how digital identity can work without central authorities, using cryptography to ensure trust.

Real-World Scenario: How DIDs & VCs Work

Imagine Sarah is graduating from university and needs to prove her degree to employers:

🎓 The Traditional Way (Problems)

  1. •Sarah gets a paper diploma (can be forged)
  2. •Employers must call the university to verify (time-consuming)
  3. •University database could be hacked or go offline
  4. •Sarah has no control over her own credentials

🔐 The DID & VC Way (Solutions)

  1. •Sarah creates her DID - Her own cryptographic identity that she controls
  2. •University issues a VC - They digitally sign her degree with their DID
  3. •Instant verification - Employers verify the signature mathematically
  4. •Tamper-proof - Any changes invalidate the signature
  5. •Always available - No need to contact the university

🚀 Try This Scenario Yourself

Let's simulate Sarah getting her university degree credential:
  1. •Sarah (You): Generate your personal DID and copy it - you'll need to share it with the university
  2. •University: Generate an institution DID to represent the university
  3. •Issue Degree: Manually paste Sarah's DID and issue her a credential, then copy the credential
  4. •Employer: Paste the credential you received to verify its authenticity
The manual copy-paste simulates real-world communication where different parties don't share the same system!

Try It Yourself

The explorer above lets you play all three roles in the credential ecosystem:
  1. •As an Individual - Generate your personal DID (your digital identity)
  2. •As an Institution - Issue a credential to someone by entering their DID
  3. •As a Verifier - Verify the credential's authenticity through cryptography
Watch the animations to see:
  • •How institutions cryptographically sign credentials
  • •The step-by-step verification process
  • •Why tampering is impossible without the private key

Why This Matters

  • •You own your identity - No company or government controls your DID
  • •Instant verification - No phone calls, no waiting
  • •Cannot be forged - Cryptography makes fakes impossible
  • •Privacy-preserving - Share only what's needed
  • •Works offline - No central server required
