How it works
Simple for the user, cryptographically sound under the hood
1. User browses normally
The user visits any web server: banking, social media, government portals. Nothing changes for the server.
2. The verifier witnesses the encrypted data
With TLSNotary the verifier makes sure the user can not cheat.
3. Share only what you choose
The user is in full control of what is shared. The verifier knows it is authentic.
Why TLSNotary?
10+ years of research. Developed at the Ethereum Foundation
Universal
No server changes needed. Works with any HTTPS website.

Apache 2.0 / MIT licensed. Built as a public good, no vendor lock-in.
Private
Choose exactly what to reveal. Redact everything else. Zero-knowledge proofs for sensitive data.
Secure
Pure cryptography. No trusted hardware. Multi-party computation and state of the art cryptographic primitives.
Portable
Your data moves with you. Break free from walled gardens while keeping your history and reputation.
