StealthNote Uses Zero-Knowledge Proof to Let Employees Go Incognito

The app is designed for employees who want to share thoughts or concerns about their workplace without revealing their identity. Instead of asking for names or personal details, it checks if the person has access to a company email address, without exposing that address.

This is done through a method called zero-knowledge proof, which allows someone to confirm they have certain information without actually showing it.

StealthNote verifies a user's connection to a company domain through their Google login token. Aztec developer Saleel Pichen explained in a April 14 post on X that the platform creates a zero-knowledge proof based on that token, which confirms the user is part of a specific company.

Since the first test message on February 1, people from the Ethereum Foundation, StarkWare, Scroll, and universities like Columbia and Cornell have tried the app.

Most of the posts have been short greetings or messages supporting privacy tools. One user from CoinFund wrote, "Give me a zk proof, and I shall anon for a day. Teach me to zk prove, and I shall anon for a lifetime".

Meanwhile, Ethereum co-founder Vitalik Buterin recently posted on Warpcast about the value of apps built on Ethereum. What did he say? Read the full story.
