Cwtch, a decentralized messaging protocol, prioritizes privacy and security. The name, derived from the Welsh word for "a hug that creates a safe place," embodies its core philosophy. Participants can create their own secure spaces within the network without relying on a central service. The protocol is open, allowing for the development of various applications and interfaces that can interact with Cwtch.

In terms of privacy, Cwtch ensures end-to-end encryption for all communication, utilizing Tor v3 onion services for secure data transmission. Additionally, the protocol is designed to be metadata resistant, meaning no data is shared without explicit consent, safeguarding user information at all levels.
