Gloebit is a virtual currency accepted on about forty different OpenSim grids. It is the most popular currency on the hypergrid by a very large margin.
Gloebit works roughly similar to PayPal. Users create a Gloebit account on the website, transfer money into it, and can then spend that money as they travel the hypergrid.
