Stellar is a decentralized blockchain network designed to streamline global financial transactions, connecting individuals, institutions, and payment systems across borders with speed, efficiency, and low cost. Since its launch in 2015, Stellar has emerged as a key player in the digital finance ecosystem, particularly in cross-border payments and financial inclusion. Built on innovative consensus technology and driven by a nonprofit foundation, Stellar aims to unify fragmented financial systems into a single, interoperable network.
The Origins of Stellar
Founded in 2014 by Jed McCaleb—co-founder of Ripple—Stellar was developed under the stewardship of the Stellar Development Foundation (SDF), a nonprofit organization dedicated to expanding financial access worldwide. The network officially launched in 2015 with a bold vision: to bridge traditional finance and digital currencies by enabling fast, low-cost transfers of any form of money, whether fiat currencies like USD or EUR, or cryptocurrencies such as Bitcoin.
Unlike traditional banking infrastructures that suffer from slow settlement times and high fees, especially for international transfers, Stellar offers a scalable alternative. It allows users to create, send, and trade digital representations of value across different asset types seamlessly. This interoperability makes it especially valuable for remittances, micropayments, and banking the unbanked.

How Stellar Works: The Science Behind the Speed
At the heart of Stellar’s efficiency lies its unique consensus mechanism: the Stellar Consensus Protocol (SCP). Unlike proof-of-work blockchains like Bitcoin, which rely on energy-intensive mining, SCP operates as a "federated Byzantine agreement" system. This means it achieves network-wide agreement without requiring a central authority or competitive mining process.
SCP enables fast transaction finality—typically within 3 to 5 seconds—with minimal computational overhead. Because it’s leaderless and decentralized, the protocol resists censorship and single points of failure while maintaining high throughput. All participants in the network maintain a shared view of transaction history, ensuring transparency and consistency across nodes.
This design makes Stellar particularly well-suited for financial institutions, payment providers, and central banks exploring digital currency solutions. By reducing dependency on intermediaries, Stellar significantly lowers transaction costs and accelerates settlement times—critical advantages in today’s global economy.
Understanding XLM: The Role of Lumens
The native cryptocurrency of the Stellar network is Lumen (XLM). While not used as a store of value like Bitcoin, XLM plays several vital functional roles within the ecosystem:
- Transaction Fees: Every operation on the Stellar network incurs a minimal fee—just 0.00001 XLM—which helps prevent spam and distributed denial-of-service (DDoS) attacks.
- Minimum Balance Requirement: To participate in the network, each account must hold at least 1 XLM, creating a small barrier to entry that discourages malicious actors from creating countless fake accounts.
- Bridge Currency: XLM acts as an intermediary during multi-currency transactions. When sending funds across different currencies (e.g., USD to JPY), Stellar automatically converts the amount into XLM before converting it into the recipient’s local currency. This built-in atomic swap functionality ensures liquidity and speed without relying on third-party exchanges.
It’s important to note that XLM cannot be mined. Unlike Bitcoin or Ethereum (pre-PoS), all Lumens were pre-created. Initially, 100 billion XLM were issued in 2014, but following community governance decisions, the total supply was reduced to 50 billion to improve scarcity and economic sustainability.
Real-World Use Cases of Stellar
Stellar’s architecture supports a wide range of practical applications:
Cross-Border Payments
Financial institutions and fintech companies use Stellar to facilitate near-instant international money transfers at a fraction of traditional costs. For example, companies like MoneyGram have integrated Stellar to enable faster remittances to underserved regions.
Central Bank Digital Currencies (CBDCs)
Several governments are exploring Stellar as a platform for issuing CBDCs due to its scalability, security, and compliance-ready framework. Ukraine and Nigeria have both tested digital currency pilots on the Stellar network.
Financial Inclusion
Through partnerships with mobile money providers, Stellar brings basic financial services to unbanked populations in Africa, Southeast Asia, and Latin America. Users can access savings, credit, and payment tools via simple mobile apps linked to the Stellar blockchain.

Frequently Asked Questions (FAQ)
Q: Can you mine XLM?
A: No, XLM cannot be mined. All tokens were pre-created at launch, and the total supply is fixed at 50 billion after a community-led reduction from the original 100 billion.
Q: What is the purpose of XLM in the Stellar network?
A: XLM serves three main functions: preventing spam through minimal transaction fees, enforcing a minimum account balance, and acting as a bridging currency for cross-asset trades.
Q: How fast are Stellar transactions?
A: Transactions on the Stellar network settle in 3 to 5 seconds, making it one of the fastest blockchain platforms for payments and asset transfers.
Q: Is Stellar decentralized?
A: Yes. Thanks to the Stellar Consensus Protocol (SCP), the network operates without a central authority. It relies on a federated model where trusted nodes validate transactions collectively.
Q: Who uses the Stellar blockchain?
A: Major users include fintech firms like MoneyGram, central banks piloting digital currencies, NGOs promoting financial inclusion, and developers building decentralized applications (dApps).
Q: How does Stellar differ from Ripple?
A: While both networks focus on cross-border payments and were co-founded by Jed McCaleb, Stellar is nonprofit-driven and emphasizes inclusivity and open access, whereas Ripple targets institutional banking clients with proprietary solutions.
