Cwtch

Cwtch is a decentralized messaging protocol that allows users to host their own safe spaces and communicate securely. Key features include end-to-end encryption, metadata resistance, and the ability to run over Tor v3 onion services. The protocol is open and decentralized, allowing anyone to implement and integrate it into their own applications. Technical implementation details include the use of onion services for communication and a design that prioritizes user consent and metadata resistance. Use cases for Cwtch include secure communication for individuals and organizations, as well as applications in fields such as journalism and activism. A unique differentiator of Cwtch is its focus on metadata resistance, which sets it apart from other secure messaging protocols.
