Online platforms that restrict access based on age—like e-commerce sites selling alcohol or adult content providers—often require users to repeatedly verify their identity through inconvenient methods. This creates frustration, raises privacy concerns, and complicates compliance for businesses. A centralized, privacy-preserving verification system could eliminate these pain points by allowing users to confirm their age once and share it securely with multiple services.

The core solution: A one-time verification hub

One way this could work is through a trusted third-party service where users verify their age using government IDs, bank credentials, or other secure methods. Instead of sharing sensitive documents repeatedly, they'd receive a token that simply confirms whether they meet age requirements (e.g., "over 18") when queried by participating platforms. The system might use:

• Cryptographic proofs to validate age without revealing birthdates
• User-controlled permissions to decide which services can check their status
• Geofencing to automatically comply with regional laws (e.g., drinking age variations)

Why stakeholders would participate

For users, this reduces hassle and minimizes personal data exposure. Businesses could replace costly verification processes with a single API call, while regulators gain a standardized way to enforce age restrictions. Early adoption might focus on high-compliance industries like alcohol delivery or gambling platforms, where the cost of manual verification is already significant.

Implementation path

An MVP could start by partnering with niche services that have strong age-gating needs, using existing digital ID systems (like bank logins) for verification. As network effects grow—more users leading to more platform participation—the system could expand horizontally across industries and vertically with governments exploring digital identity programs.

Compared to existing solutions, this approach differs by focusing narrowly on reusable age confirmation rather than full identity sharing, prioritizing both convenience and privacy in a way no current service combines.
