Aztec launches StealthNote app giving privacy to corporate whistleblowers

Developers behind the Ethereum layer 2 Aztec Network have
launched a whistleblowing platform called StealthNote that allows
workers to vent about their employer without revealing
themselves.
StealthNote uses zero-knowledge proofs to prove that posts on
its platform are written by someone with access to an email address
of the company that they’re reviewing.
Aztec Labs developer Saleel Pichen wrote in an April
14 X post that StealthNote creates a zero-knowledge proof of a
Google JSON Web Token, which is used to authenticate users and
allows the platform to prove a poster owns “an email from a company
domain without revealing any personal info.”

According to Aztec’s documentation,
the privacy solution had been in development since at least Oct.
22, while the first test post from Aztec occurred
about three months ago.
Workers from Ethereum Foundation, StarkWare and Scroll as well
as Columbia and Cornell universities have made posts on
StealthNote, primarily sharing greetings and voicing their support
for privacy solutions.
“Let’s make privacy cool again,” a worker from Nim Network
wrote.
ZK-proofs needed more than ever, says Buterin
ZK-proofs have become an increasingly used
privacy
solution in the internet age as concerns over data security and
government
surveillance continue to grow.
The concerns were raised in an April 14 blog post by Ethereum
co-creator Vitalik Buterin, who criticized
the assumption that governments are generally well-intentioned when
it comes to sacrificing privacy for a more “transparent
society.”

He championed ZK-proofs as a solution to mitigate this
trade-off, highlighting the technology’s ability to provide
“fine-grained control of who can see what information.”

The privacy-focused Aztec Network launched on Ethereum in
February 2020.
The firm raised $100 million in
Series B funding led by the tech-focused venture capital firm
Andreessen “a16z” Horowitz in December 2022, with A Capital and
King River also contributing.
