What if users could prove who they are without revealing any private info? Welcome to zero-knowledge proofs (ZKP) — the future of privacy. In this talk, we’ll demystify ZKPs and show how to use them inside Flutter apps for scenarios like private age/identity verification, voting, and secure form inputs.

Outline:

1. Intro to Zero-Knowledge Proofs (ZKPs)

2. Why ZKP matters in mobile UX

3. Integrating ZKPs with Flutter using APIs (e.g., zk-SNARK backends)

4. Real-world use cases:

a. Anonymous surveys

b. Proof of age without showing birthdate

5. Demo + code breakdown

Demo: A form-based app with an embedded ZKP use case (e.g., “prove you're 18+ without sending your DOB”)

Key Takeaways:

A. Understand what ZKPs are and how they can be used in mobile apps.

B. Learn to integrate privacy-preserving proofs in real-world scenarios (age, identity, votes).

C. Explore libraries, APIs, and backends that support ZKP in Flutter.
