Stellar Lumens (XLM) is one of the most prominent blockchain-based payment networks in the world. Designed to facilitate fast, low-cost cross-border transactions, it has consistently ranked among the top cryptocurrencies by market capitalization.
The Stellar network aims to connect financial systems and people across the globe, striving for a more inclusive and accessible digital economy. Its native cryptocurrency, Lumens (XLM), serves as the bridge asset that powers transactions and maintains network security.
This guide explores how Stellar Lumens works, its key features, real-world applications, and what makes it a unique player in the blockchain space.
What Is Stellar Lumens?
Stellar Lumens is an open-source blockchain network designed to make financial services more accessible and affordable. It enables near-instant transfers of value—whether in traditional currencies like USD or EUR, or other digital assets—anywhere in the world.
Founded in 2014 by Jed McCaleb, who also co-founded Ripple, Stellar was created to improve upon existing payment systems by making them faster, cheaper, and more transparent. Unlike fully decentralized cryptocurrencies like Bitcoin, Stellar operates with a partially centralized governance model managed by the Stellar Development Foundation (SDF), a non-profit organization.
Key characteristics of Stellar include:
- Fast and low-cost transactions
- Native token: XLM
- Primary use case: cross-border payments and remittances
- Eco-friendly consensus mechanism
The Origins of Stellar
Stellar was launched in 2014 by Jed McCaleb and Joyce Kim. McCaleb, a well-known figure in the crypto space, had previously founded Mt. Gox and was a co-founder of Ripple. After leaving Ripple due to strategic differences, he used Ripple’s original codebase to build Stellar as a more open and accessible alternative.
The project received early support from payments company Stripe, which provided $3 million in seed funding. In return, Stripe received 2 billion XLM tokens.
Over the years, Stellar has formed partnerships with major companies including IBM and Deloitte. One of its most notable collaborations was with IBM in 2017 to develop cross-border payment corridors in the South Pacific, aiming to improve financial connectivity for smaller nations and businesses.
How Does Stellar Lumens Work?
The Stellar network uses blockchain technology to record transactions and account balances. However, it does not rely on Proof-of-Work (like Bitcoin) or Proof-of-Stake (like Ethereum) for consensus. Instead, it uses the Stellar Consensus Protocol (SCP), which is faster, more energy-efficient, and capable of processing up to 1,000 transactions per second.
Transactions on Stellar are verified every 5 seconds by nodes running Stellar Core software. Anyone can operate a node, which contributes to network security and decentralization. Still, the system is designed to be more efficient than fully decentralized networks, making it suitable for high-volume payment processing.
To send money across borders using Stellar, users often rely on anchors—trusted entities that convert local currency into XLM or other supported assets. For example:
- A user in Finland wants to send euros to Sweden.
- A Finnish anchor converts euros to XLM.
- XLM is sent to a Swedish anchor via the Stellar network.
- The Swedish anchor converts XLM back to euros for the recipient.
This process typically takes less than 5 seconds and costs a fraction of a cent per transaction.
Stellar Consensus Protocol (SCP)
The Stellar Consensus Protocol is a decentralized model that does not require mining. Instead, nodes form trust groups called quorum slices. When a transaction is approved by all trusted nodes in a slice, it is considered confirmed.
This mechanism allows Stellar to achieve consensus without the high energy consumption or slow transaction times associated with traditional blockchain networks.
Stellar Lumens vs. Ripple (XRP)
Stellar and Ripple are often compared due to their shared founder and similar goals—improving cross-border payments. However, there are key differences:
- Governance: Stellar is run by a non-profit (SDF), while Ripple is a for-profit company.
- Decentralization: Stellar is more decentralized than Ripple, which maintains tighter control over validator nodes.
- Target audience: Ripple focuses on serving large financial institutions and banks. Stellar aims to serve individuals, small businesses, and underserved communities.
- Tokenomics: Both XLM and XRP have fixed supplies, but XLM has a built-in 1% annual inflation mechanism (though this was largely disabled by a community vote in 2019).

What Makes Stellar Unique?
Stellar’s main advantage is its ability to handle multi-currency transactions with ease. Users can send and receive any currency—traditional or digital—as long as there is a willing anchor or market maker supporting that asset.
Other standout features include:
- Low fees: Transaction costs are negligible, usually amounting to $0.00001 or less.
- Speed: Settlements occur within seconds.
- Interoperability: Stellar can integrate with existing financial infrastructure.
- Smart contracts: While not as advanced as Ethereum, Stellar supports smart contracts and tokenization through its Stellar Smart Contracts (SSC) platform.
The network is open-source, meaning developers can build decentralized applications (dApps), digital assets, and custom financial products on top of Stellar.
The XLM Token
XLM is the native cryptocurrency of the Stellar network. It serves three main purposes:
- Transaction fees: Each transaction costs a small fee (0.00001 XLM) to prevent spam.
- Minimum account balance: Users must hold at least 1 XLM in their wallet to activate and maintain an account.
- Bridge asset: XLM is often used as an intermediary currency in cross-currency transactions.
The total supply of XLM was initially 100 billion. However, the Stellar Development Foundation burned more than half of the supply in 2019, reducing it to 50 billion. There is no mining; all XLMs were created at launch.
Use Cases and Adoption
Stellar is particularly useful in:
- Remittances: Migrant workers can send money home faster and cheaper than with traditional services.
- Banking the unbanked: Stellar offers financial tools to people in developing countries who lack access to banks.
- Microtransactions: Its low fees make it ideal for small payments and streaming revenue models.
- Asset tokenization: Companies can tokenize real-world assets like gold or real estate on Stellar.
Major companies and institutions that have partnered with or built on Stellar include IBM, Franklin Templeton, and the Ukrainian government, which used Stellar to develop a digital currency framework.
