Delta Chat is an e-mail instant messenger that is just becoming available on all platforms. Unlike other offerings, Delta Chat is no platform and operates no own servers. Instead it uses existing SMTP/IMAP servers to send and receive messages. We'll talk about the current development status on all platforms, our new Rust-core based approach, our decentralized e2e-encryption facilities (not requiring keyservers, and safe against active attacks) and how we are generally driving developments from UX and security perspectives. We also aim to showcase "burner accounts", a new concept that we are developing and discussing with activists in eastern european countries and asian cities.
