The most private and secure chat and application platform
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 messaging application built on the SimpleX platform.
What is SimpleX?
There is currently no messaging application other than SimpleX Chat that guarantees metadata privacy - who is communicating with whom and when. SimpleX is designed to not use any permanent users identities to protect meta-data privacy. See SimpleX overview for more details.
SimpleX protocol changes
Best possible E2E encryption - the only messenger using two-layer E2E encryption, with one layer using double ratchet protocol that provides forward secrecy and break-in recovery, and additional encryption layer providing meta-data protection. See more details about encryption algorithms in SimpleXMQ change log.
Performance and space efficiency improvements - protocol overhead is reduced from circa 15% to 3.7% thanks to binary encoding, and performance is substantially improved due to more efficient cryptographic algorithms.
Shorter invitation and contact links due to switching from long RSA to much shorter Curve448/25519 keys - for example, you can connect to the team via team's SimpleX Chat contact address (you need to use it in terminal app) or just by using /simplex command in the chat.
