The article profiles Aevum, a developer SDK that uses zero-knowledge cryptography to verify user age on-device without storing identity documents, solving the regulatory pressure on apps to verify minors while avoiding privacy risks. It's positioned as a better alternative to traditional ID scanning because developers never handle personal data, yet still satisfy compliance mandates like COPPA.

• Apps face impossible tradeoffs: verify age or face legal liability, but traditional verification (uploading IDs, facial scans) destroys conversion rates and creates massive data breach targets
• Aevum generates cryptographic proof a user meets age thresholds directly on their phone using WebAssembly, with developers charging $0.03-$0.10 per verification and $499/month for enterprise tiers
• The moat comes from integration lock-in (replacing it requires re-architecting onboarding) plus cross-app identity reuse, where users verify once and get frictionless access across partner apps
