LUME is an anonymous, end-to-end encrypted messaging system where the server acts as a blind relay. It stores and forwards opaque encrypted payloads without access to plaintext or keys. Your identity is an Ed25519 key pair derived from a BIP39 phrase, meaning no phone number or email is required. Messages use X3DH key agreement and a Double Ratchet. The source code is available for viewing and auditing under a strict license.

Hi everyone! 👋 I'm excited to share LUME.We built this to create an end-to-end encrypted messaging system where the server is truly a blind relay. The server only stores and forwards opaque encrypted payloads and never sees plaintext. To ensure true anonymity, your identity is an Ed25519 key pair derived from a BIP39 phrase. We don't ask for phone numbers, emails, or passwords. All cryptography runs exclusively on the client, utilizing protocols like X3DH key agreement and a Double Ratchet. Transparency is critical, so our repository is source-available for viewing and review. Note that this is NOT an open-source or free-software license, as running or modifying the code requires a separate agreement. I'd love to hear your thoughts on our approach to client-side cryptography and server architecture!

using a BIP39 phrase as the sole identity is a really sharp call here, cuts straight past the phone number trap that burns most so called private messengers.
