Stellar Lumens (XLM)The mission of the Stellar Development Foundation (SDF) is to promote global financial access, literacy, and inclusion. SDF accomplishes this by expanding worldwide access to low-cost financial services through the development and maintenance of technology and partnerships.

SDF’s vision is an open and affordable financial system where people of all income levels can access simple-to-use, secure, and low cost financial services. SDF also aims to empower developers with useful technology to create financial products and services for their communities.
Lumens are the native asset of the Stellar network. Native means that lumens are built into the network. Asset is how the network refers to an item of value that is stored on the ledger.

One lumen is a unit of digital currency, like a bitcoin.

While you can’t hold a lumen in your hand, they are essential to the Stellar network—they contribute to the ability to move money around the world and to conduct transactions between different currencies quickly and securely.

In 2014 the Stellar network launched with 100 billion stellars, the original name of the network’s native asset.

In 2015, with the launch of the upgraded network, the name of the native asset changed from stellar to lumen to distinguish it from 1) the Stellar network itself and 2), the nonprofit organization that contributes to development of the network.

The Stellar network offers all of the innovative features of a shared public ledger on a distributed database—often referred to as blockchain technology. The Stellar network’s built-in currency, the lumen, serves two purposes.
