Obsidian is a privacy and security focused app hosting platform built in C#. The platform is based on the proven technology of Stratis utilizing both masternodes as well as service nodes. Unlike many other coins that use Proof-of-work, Obsidian uses Proof-of-Stake, which is much more cost effective and gives coin holders an advantage over mining farms. Additionally, Obsidian assists with incubation and development of new apps on their platform through their startup incubator. The flagship application on the platform is the Obsidian Secure Messenger (OSM). OSM provides full anonymity, end-to-end encrypted file/message sharing, and the ability to send/receive the coin via your mobile device.
