SELECTIVE DISCLOSURE
Share only what is necessary. Prove a fact — like your age or verification level — without handing over your full identity document.
THE OVERSHARING PROBLEM
Most online checks ask for far more than they need. To enter a venue you upload your passport. To open an account you send document photos to every partner. Each copy increases leak risk and user friction.
- Verifiers collect full documents when a yes/no answer would suffice
- Users cannot limit what fields leave their wallet
- Data copies multiply across banks, apps, and vendors
HOW IT WORKS
Your wallet holds a signed credential with several attributes — name, age, verification level, country, and more. When a service asks a question, you answer with only the relevant fields. The signature still proves an issuer you trust vouched for that answer.
- You decide what to share on every request
- Apps can only verify the claims you present — not your whole file
- Revoked or expired credentials are rejected automatically
- Zero-knowledge proofs will extend this further — prove a fact without revealing the underlying data (roadmap)
