CWTCH
Privacy Preserving Messaging
Cwtch /kʊtʃ/
Cwtch (/kʊtʃ/ - a Welsh word roughly translating to “a hug that creates a safe place”) is a decentralized, privacy-preserving, multi-party messaging protocol that can be used to build metadata resistant applications.
Participants in Cwtch can host their own safe spaces, or lend their infrastructure to others seeking a safe space. There is no “Cwtch service” or “Cwtch network”. The Cwtch protocol is open, and anyone is free to build bots, services and user interfacesand integrate and interact with Cwtch.
All communication in Cwtch is end-to-end encrypted and takes place over Tor v3 onion services.
Cwtch has been designed such that no information is exchanged or available to anyone without their explicit consent, including on-the-wire messages and protocol metadata.
