Private proof of attendance

Prove you were there. Without exposing who you are.

WiFiProof is a privacy-preserving attendance system that verifies real-world presence using WiFi and zero-knowledge proofs.

Built for events, classrooms, and any environment where presence matters.

What gets checked

Real presence. Minimal data.

WiFi

Venue WiFi helps confirm the check-in is happening in the right place.

Proof

Local zero-knowledge proofs confirm presence without exposing raw location data.

Venue Wi-Fi anchors the check-in
Location proof runs locally
Onchain records for events, institutional records for schools

What it does

Verify attendance without abuse or surveillance.

WiFiProof confirms that someone was physically present without collecting unnecessary personal data.

02

Verify presence

Venue WiFi and local proof generation confirm that the check-in is happening on-site.

03

Write the record

Onchain records for events. Institutional records for schools.

FAQ

Frequently asked questions.

Everything people usually want to know right away.

A QR code alone can be screenshotted, forwarded, or claimed remotely. WiFiProof adds venue network checks, local ZK proximity proofs, and verifiable records so the attendance signal is harder to fake.
