We are building a new platform for distributed Internet applications where privacy of the messages and the network matter. SimpleX Chat is our first application, a chat app built on the SimpleX platform.<p>There is currently no messaging app other than SimpleX Chat that guarantees metadata privacy - who is talking to whom and when. SimpleX is designed to not use any permanent users identities to protect meta-data privacy. See SimpleX overview for more details: <a href="https://github.com/simplex-chat/simplexmq/blob/master/protocol/overview-tjr.md" rel="nofollow">https://github.com/simplex-chat/simplexmq/blob/master/protoc...</a><p>SimpleX v1 has big changes in E2E encryption (now with double-ratchet), protocol encoding (overhead in transmitted bytes is reduced from 15% to 3.7%), performance and invitation link size (no more long RSA keys in URLs, we switched to Curve448/25519 keys). See more details via the link.<p>We really look forward to you playing with it - you can connect to the team via /simplex command in the chat (myself or somebody else will meet you there) - you feedback and questions.
