Nice try, FBI. Anyway, I will answer as I like a good challenge. This depends on your threat model, and there’s a spectrum of protection. ### Client-side masking Assume that the group only includes trustworthy members (gentleman’s agreement). Their goal is to reduce possible exposure against acquisition of a long term chat log stored on each device (e.g., rubber hose cryptography, stolen backup, malware installed later) and to fight against unintended cognitive biases related to who is talking vs. what they are actually saying. Messages would be stored with all identifiers stripped or mocked either by DC or using webxdc. ### Each member registers a dedicated profile and use a DC group Chatmail server would still have access to the mapping of who said what and can trace back the client IP, miscellaneous network fingerprint and user activity. This problem could be lessened if every member used an overlay network such as Yggdrasil, I2P or Tor to access their chatmail relay hosted centrally or on localhost. Unfortunately, setting that up can be a hassle. ### Members use the same single profile by sharing its password and key > [@DeltaFans anonymous community](https://support.delta.chat/t/deltafans-anonymous-community/3038/1): > > I created DeltaFans, a fully anonymous disguised_face (and encrypted!) community experiment. Once inside you will have a shared anonymous space, you can create new groups/threads and they will be accessible to the whole community, you can send messages anonymously or pseudo-anonymously if you set a nick for yourself. You can even make public read-only channels from your normal personal account and make it available in the community by creating a “broadcast list” and adding the community addre… > [@How to create a channel with shared administration](https://support.delta.chat/t/how-to-create-a-channel-with-shared-administration/4630/1): > > Background There are many situations where it is useful to have more than one person who is able to post to a Delta Chat channel.

It could either run fully client-side over P2P (possibly via webxdc) or by a fleet of entry, middle and exit server nodes. > **[Mix network](https://en.wikipedia.org/wiki/Mix_network)** > > Mix networks are routing protocols that create hard-to-trace communications by using a chain of proxy servers known as mixes which take in messages from multiple senders, shuffle them, and send them back out in random order to the next destination (possibly another mix node). This breaks the link between the source of the request and the destination, making it harder for eavesdroppers to trace end-to-end communications. Furthermore, mixes only know the node that it immediately received the Each ... --- _[View the full topic](https://forum.delta.chat/t/fully-anonymous-group-chats/4875)._
