I'd really appreciate your feedback, criticism and suggestions on the open-source idea I was slowly working on since early 2020. I recently made the demo server for the low-level message queue protocol ("simplex messaging protocol") and the website to try to explain the chat idea that would use this protocol.

If anything, it was definitely helping to get to know Haskell types etc. much deeper than before :)

Any criticism would be great - thank you in advance!

Announcing SimpleX Chat Prototype!

Published: May 12, 2021

For the last six months me and my son Efim have been working to bring you a working prototype of SimpleX Chat. We're excited to announce SimpleX Chat terminal client is now available here on Linux, Windows and Mac (you can either build from source or download the binary for Linux, Windows or Mac from the latest release).

We’ve been using the terminal client between us and a few other people for a couple of months now, eating our own “dog food”, and have developed up to version 0.3.1, with most of the messaging protocol features we originally planned

We need your help!

We're building a new kind of chat network - the only network that lets you control your chat. We'd really appreciate your feedback, criticism and support - a star on the github repo, signing up to the mailing list or any contribution to the project will help. There is so much more to do!

The first application built on the platform is Simplex Chat, which is available for terminal (command line in Windows/Mac/Linux) and as iOS public beta - with Android app coming in a few weeks. The platform can easily support a private social network feed and a multitude of other services, which can be developed by the Simplex team or third party developers.

SimpleX also allows people to host their own servers to have control of their chat data. SimpleX servers are exceptionally lightweight and require a single process with the initial memory footprint of under 20 Mb, which grows as the server adds in-memory queues (even with 10,000 queues it uses less than 50Mb, not accounting for messages). It should be considered though that while self-hosting the servers provides more control, it may reduce meta-data privacy, as it is easier to correlate the traffic of servers with small number of messages coming through.

Further details on platform objectives and technical design are available in SimpleX platform overview.

    Optimized battery and traffic usage - up to 90x reduction

    To reduce battery and traffic usage this release updated SMP protocol to allow batching multiple server commands (up to 90!) into one traffic block – provided both the server and the client are upgraded. It means that if you have 90 contacts (or group members) on one server, to subscribe to all messaging queues you now need to send only one 16kb block instead of ~1.5Mb of traffic (90 blocks). It also hides how many contacts you have from any attackers who observe your network.

    You might notice that sending commands to multiple queues in one block would allow the server to correlate that all these queues belong to the same user, even though the current server implementation we use does not do it. But even without batching, as the commands are sent via the same TCP connection, this correlation was already possible, so compared with the previous version it has no downsides.

    To mitigate the risk of servers correlating your messaging queues we will soon add an option to access each queue via a separate TCP connection, which will have to be used together with access via Tor (as otherwise the servers would still see the same IP address). While it will increase battery and traffic consumption, it will also provide the highest level of privacy.
