The Problem
Referral programs power growth in banking apps, e-commerce, gaming, even basic utilities, but they’re magnets for abuse:
Self-referrals - one person spins up 20 accounts to farm bonuses.
Bot armies automate sign-ups to drain promo budgets in hours.
Fake-friend chains skew campaign metrics and cloud lifetime-value data.
Manual audits & CAPTCHAs slow real users yet still miss sophisticated Sybil networks.
Brands overspend, growth teams can’t trust the numbers, and genuine advocates feel undervalued.
The Solution
Proof of Humanity adds a unique, human credential to every account involved in a referral.
One human, one reward - A referral counts only when the new account presents a live, privacy-preserving credential.
Zero bot farming - Scripts and duplicate wallets can’t mint extra credentials, closing the "multi-sign-up" loophole.
Plug-and-play fairness - Whether it’s a banking bonus, an e-commerce coupon, or an in-game skin, the same credential logic applies.
Privacy first, global reach - Participants prove "real person, unique account" without handing documents to every brand.
How It Works
Credential enrolment – Users complete a quick palm scan and receive their Proof-of-Humanity credential once.
Referral link – The referrer shares the link in the usual way.
Credential check – When the invitee signs up, the system verifies that their credential is valid and different from the referrer’s.
Reward release – The bonus credits only after the credential check passes, guaranteeing one reward per real person.
Benefits & Results
Promotion spend reaches genuine customers, not bots.
Reliable customer-acquisition and lifetime-value metrics.
Minimal friction for real users - no selfies or document uploads.
Reduced fraud-handling costs for support and compliance teams.
