+        Welcome to Oxen.
+
+        Oxen believes privacy is an important part of our future. People have been safeguarding the right to privacy since the dawn of humanity, but the digital world has turned privacy into a privilege. Enough is enough. We're taking it back. For you. For us. For everyone.

+        Oxen is a private technology stack including the Oxen blockchain, Oxen service nodes (Session’s servers), the Oxen cryptocurrency, an onion-router called Lokinet, and Session itself.
+        
+        Oxen is what makes Session possible — Session is running on the Oxen network right now.
