The Obsidian Secure Anonymous Messenger allows for sending end-to-end encrypted messages, media, and files and is optimized for anonymity of communication and metadata protection/avoidance and does not require any user accounts, phone number or personal email address which could identify its users. The message transport will be accomplished by a decentralized network of special messaging masternodes that can be run by anyone by simply installing the respective software. Running messaging masternodes will be rewarded in Obsidian currency, so that messenger users and messenger masternode hosters form an economy which is independent from any company or country and maintained only by the open source community.
