Stellar Lumens (XLM) Information{coin_name} ({symbol}) Information

Move Money Across Borders Quickly, Reliably, And For Fractions Of A Penny.

XLM is the native asset of the Stellar network. XLM is needed for transaction fees and minimum balances on accounts in order to prevent people from overwhelming the network and to aid in prioritization. XLM can also facilitate trades between pairs of currencies between which there is not a large direct market, acting as a bridge. This function is possible when there is a liquid market between the lumen and each currency involved.

Questions and AnswersQuestions and Answers

What are lumens?
One lumen (XLM) is a unit of digital currency, like a bitcoin. 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.
Where did lumens come from?
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.
Why does the Stellar network need a native asset?
The Stellar network offers the innovative features of a shared public ledger on a distributed, global database — often referred to as blockchain technology. The Stellar network’s built-in currency, the lumen, serves two purposes: First, lumens play a small anti-spam role. Lumens are needed for transaction fees and minimum balances on accounts on the Stellar network in order to prevent people from overwhelming the network and to aid in prioritization. Each transaction has a minor fee—0.00001 lumens—associated with it. This fee prevents users with malicious intentions from flooding the network (otherwise known as a DoS attack). Lumens serve as a security measure that mitigates DoS attacks that attempt to generate large numbers of transactions or consume large amounts of space in the ledger. Similarly, the Stellar network requires all accounts to hold a minimum balance of 0.5 lumens. This requirement incentivizes users to declutter the ledger by eliminating abandoned accounts, thereby that ensuring that all accounts are likely to have economic utility on the network. Second, lumens may facilitate multi-currency transactions. Lumens sometimes facilitate trades between pairs of currencies between which there is not a large direct market, acting as a bridge. This function is possible when there is a liquid market between the lumen and each currency involved.
What is XLM?
XLM is shorthand for lumen. Most currencies have 3-letter codes (USD, EUR, AUD, BTC) as an international standard.
Who governs lumen creation?
Lumen supply is determined by fixed, protocol-level rules. The number of lumens created at genesis was 100 billion. Every year, there is a 1% inflation rate. New lumens cannot be generated arbitrarily by anyone.
How does inflation work with lumens? Why is there inflation?
The Stellar network has a built-in, fixed inflation mechanism. New lumens are added to the network at the rate of 1% each year. The network also collects a base fee for each operation in a transaction. The funds from base fees are added to the inflation pool. As a balancing measure for the ecosystem, anyone who holds lumens can vote on where the funds in this pool go. Each week, the protocol distributes these lumens to any account that gets over .05% of the votes from other accounts on the network.
How are lumens distributed? intends to distribute the initial 100 billion lumens as follows: 50% given away to individuals : A small (50-300 XLM) amount of lumens will be given to each unique individual who signs up through an invitation link. You may get an invitation from one of our partners or by attending one of our meetups. 25% given away to partners: Lumens will be given to businesses, governments, institutions, or nonprofit organizations that contribute to the growth and adoption of the Stellar ecosystem. 20% given away to bitcoin and XRP holders: distributed lumens to holders of bitcoin and XRP (19% for bitcoin holders and 1% for XRP holders). This giveaway was completed in two rounds: one round was completed in October 2016 and another was completed in August 2017. does not intend to conduct another round of lumen giveaways for bitcoin or XRP holders. 5% reserved for operational expenses
Why is giving away lumens?
To achieve a more inclusive digital economy. Per our mission, works to connect people to low-cost financial services. Giving away lumens for free is an invitation to communities to design the services they need. Our hope is to eventually have global citizens own and use XLM, in both developing and developed economies. To expand the reach of the network. The availability and active use of lumens on the network will increase the network’s utility by many orders of magnitude. As of January 2018, we have now given away over 8 billion lumens.
Why should I buy lumens if you are giving them away for free?
As an integrator or anchor (an integrator that is trusted to accept deposits and honor withdrawals, usually a licensed money service business), you may need a large quantity of lumens to cover base fees for transactions on the network, to create and use sophisticated smart contracts, and for account creation. As a money transfer operator or market maker, you may buy and use lumens as a bridge asset to facilitate trades of different asset trade pairs on the network. As a developer or entrepreneur, you may buy and use lumens to learn about cryptocurrency, experiment with operations, and build innovative applications on the Stellar Network. In the future, after we have given away all the lumens—which will happen over the next 10 years—everyone will need to procure lumens from third parties.
