Verifyge -
When you sign up for a service (say, a stock trading app), the app sends a request to your Verifyge Wallet asking: "Is this user over 18 and a US resident?"
Your device processes the request locally. It does not send your birth date or address to the app. Instead, it runs a Zero-Knowledge Proof algorithm that answers "Yes" or "No" to the age and residency questions, backed by the government’s digital signature. verifyge
