Fighting bots in Web3 starts with proving who’s real human. Billions tech stack launched last year the first private biometric Proof of Humanity on @LineaBuild, in partnership w/ @VeraxRegistry 🧵👇
Challenge: With 5M+ monthly active wallets, Linea needed a way to: - Stop bots & Sybil attacks - Protect LXP token rewards from abuse - Keep verification privacy-first & easy for users
Billions solutions: Using @PrivadoID, the tech stack behind Billions, we power a 2-level Proof of Humanity flow: - Sign in with user wallet - 3D face scan for liveness & uniqueness (no data stored) - $1 credential → anchored to @VeraxRegistry registry - Reusable PoU
Results: - Secure, bot-resistant reward claims - Privacy preserved with ZK proofs & non-reversible facial hashes - No special hardware needed—works from any device - PoU credentials reusable across Linea dApps
Fair rewards. Stronger trust. Dive into how we work with @LineaBuild to deliver privacy-first Proof of Humanity:
