OpenArcanum is an end-to-end encrypted, accountless community chat platform positioned as a decentralized Discord alternative, with desktop apps, self-hosted community servers, relays, and maintainer nodes. It combines key-based identity, per-community key isolation, encrypted DMs, voice/video, and a documented threat model, making it an ambitious privacy-first take on federated group chat.

Target audience: privacy-conscious users, self-hosters, community admins, security engineers
