Cwtch

Many messaging apps (such as Signal, Wire, and WhatsApp) have taken great strides toward making end-to-end encryption pervasive, hiding the contents of our communications from prying eyes. However, most of these tools still collect (or are able to collect) metadata: information about who is speaking, who they are speaking to, when, how often, from where, and more. This information can be used to construct our social graph, track down the people we talk to, and in some instances even infer what we are saying. Law enforcement under oppressive regimes uses these patterns on a daily basis to locate, detain, surveil, and harm our partners, our families, our friends, our comrades. In the words of former NSA director Michael Hayden, “we kill people based on metadata.”

Cwtch is an extension of the metadata resistant protocol Ricochet and supports asynchronous, multi-peer group communications through the use of discardable, untrusted, anonymous infrastructure.

This is a program definitely worth following as it develops.
