Obsidian is its own platform and on the 24th the first application for the platform will be released in a beta on the Google store for Android phones. Obsidians coin is used to incentivize the network and as a currency to transmit in the messenger application.
Unlike most blockchain messengers Obsidians application will message over a P2P network, not the blockchain. This will allow the network to scale with use and also transmit faster then any strict blockchain messenger could. (Zencash, IOC)
Obsidian is a platform that focuses on privacy and security, as such the messenger will be very secure. It will feature anonymous payments in the application so you can communicate and pay people from mobile devices without leaving a trace or your messages being viewed by unwanted parties. This will be widely utilized by people who value their own data or want to stay discrete.
You will be able to sign up for the app without providing any personal information. Also important is the fact that the team intends to allow users to purchase ODN directly in-app with fiat. Depending on how you finance the Fiat you can maintain anonymity.
The Obsidian team is currently in talks with several startups to launch applications on the ODN platform that focus on privacy and security. Marketing and exchange applications will begin after the release of the app on the 24th. I really do think this coin is severely overlooked and its market cap will soon adjust to being much higher than it is now.
