International payments are notoriously slow and costly. A simple transfer can take days, bouncing between banks and intermediaries before it lands in the recipient’s account. Stellar was built to fix that problem. Its blockchain network is designed to move money across borders quickly, cheaply, and without unnecessary middlemen. At the heart of Stellar sits its native token, Lumens (XLM), which powers transactions and serves as a bridge between currencies.
A Quick Look at Stellar’s Origins
Stellar launched in 2014, co-founded by Jed McCaleb—best known for helping to create Ripple—and Joyce Kim. Their vision was straightforward: make the global financial system more open and inclusive.
The network is stewarded by the Stellar Development Foundation (SDF), a nonprofit that maintains the open-source code, supports adoption, and funds projects aimed at expanding access to financial services. The SDF’s nonprofit structure has helped keep Stellar aligned with its mission of financial inclusion, rather than short-term profit.
How the Network Works
Consensus Without Mining
Unlike Bitcoin, Stellar doesn’t rely on energy-intensive mining. Instead, it uses the Stellar Consensus Protocol (SCP), which is based on a model called the Federated Byzantine Agreement. In practice, this means each validator (a computer running Stellar Core) selects a group of trusted peers, and consensus is achieved when enough overlap exists among these groups.
The result: transactions finalize in about five seconds, with minimal fees, and without the heavy energy costs associated with proof-of-work systems.
Soroban Smart Contracts
Stellar has expanded beyond payments with Soroban, its smart contract platform. Written in Rust and compiled into WebAssembly, Soroban allows developers to create financial applications like lending tools, asset management services, or marketplaces. Instead of using a fixed minimum balance like traditional accounts, Soroban introduces a “rent-based” model, where contracts pay fees for the storage they consume.
Anchors and On/Off Ramps
Anchors are another key piece of the puzzle. These are trusted entities such as banks, fintech firms, or payment providers that connect real-world money to the blockchain. For example, a user can deposit U.S. dollars with an anchor, receive a digital tokenized version on Stellar, send it instantly across borders, and redeem it in local currency through another anchor.
Real-World Use Cases
Stellar’s design has enabled several practical applications:
- Cross-border payments: Low fees and quick settlement make it ideal for remittances.
- Asset tokenization: Bonds, commodities, and even ETFs can be issued and transferred on Stellar.
- Stablecoins: USD Coin (USDC) and other fiat-backed stablecoins already run on the network.
- Micropayments: Its efficiency supports tipping, donations, or small digital purchases.
- Financial inclusion: In regions underserved by banks, Stellar can be accessed via mobile wallets.
The Role of Lumens (XLM)
XLM is the native token of Stellar, and it serves multiple purposes:
- Transaction fees: Every transaction costs a small amount of XLM, preventing spam.
- Bridge asset: XLM can act as a middle step between two currencies that don’t have a direct trading pair.
- Minimum balances: Accounts must hold a small reserve of XLM to remain active.
- Smart contracts: On Soroban, XLM pays for contract storage fees.
When Stellar launched, 100 billion XLM were created. In 2019, the community voted to remove the inflation mechanism, and the SDF burned roughly 55 billion tokens, cutting the supply in half. Today, about 31.3 billion XLM are in circulation, with the SDF holding 18.4 billion to fund network growth.
Final Thoughts
Stellar aims to connect traditional finance with blockchain in a practical, accessible way. Its focus on speed, low costs, and inclusivity makes it stand out among blockchain projects that often struggle with scalability or usability. With Soroban expanding its smart contract capabilities and anchors linking it to the real economy, Stellar is positioning itself as more than just a payments network—it’s becoming a foundation for the next wave of decentralized financial services.
