Privacy Glossary

Open Source Software

Code anyone can inspect, verify, and trust

In Short

Software whose source code is publicly available for inspection, modification, and distribution, enabling independent security verification.

Explained

Open source software allows security researchers, developers, and users to verify that the software does what it claims. For privacy tools, this is essential - you shouldn't have to trust claims about encryption when you can verify the code yourself.

How zkChat Implements This

zkChat is fully open source under the AGPL-3.0 license. Our encryption implementation, server code, and client code are all publicly available on GitHub. You can verify our zero-knowledge claims by reading the code.
