Transparency by Design
We believe you should know exactly how your data is handled. No black boxes. No hidden servers. Just open protocols.
High-Level Architecture
Hermes is built on a stack of decentralized and privacy-preserving technologies. It combines Nostr for transport, MLS (Messaging Layer Security) for encryption, and Tor for network anonymity.
- 01
Nostr Protocol
Used as the transport layer. No central server. Relays just store encrypted blobs.
- 02
MLS Encryption
Better than Double Ratchet. Provides Group E2EE with Post-Compromise Security.
- 03
Tor Network
All traffic is routed through Tor to hide your IP address from Relays.
