Stellar is a decentralized blockchain network built to revolutionize global payments. Designed for speed, security, and affordability, it enables near-instant cross-border transactions between any pair of currencies—fiat or digital. Since its launch in 2014, Stellar has evolved into a powerful infrastructure for financial inclusion, asset tokenization, and decentralized finance (DeFi), all while maintaining an energy-efficient consensus model that scales effortlessly.
At the heart of this ecosystem lies Lumen (XLM), the native cryptocurrency that powers the network by preventing spam and enabling low-cost transactions. Backed by the nonprofit Stellar Development Foundation (SDF), Stellar has forged key partnerships with financial innovators like Circle and MoneyGram, positioning itself as a trusted platform for real-world financial applications.
How Does Stellar Work?
Stellar operates as an open-source, public blockchain that connects disparate financial systems through seamless interoperability. Unlike traditional blockchains that rely on energy-intensive mining, Stellar uses the Stellar Consensus Protocol (SCP)—a unique proof-of-agreement mechanism that achieves consensus without requiring massive computational power.
The Stellar Consensus Protocol (SCP)
SCP is built on a Federated Byzantine Agreement model, where network validators—trusted nodes run by institutions, developers, or organizations—agree on transaction validity through overlapping quorum sets. This eliminates the need for competitive mining and drastically reduces confirmation times to just 2–5 seconds.
Here’s how it works:
- Each validator selects a quorum slice, a subset of other nodes it trusts.
- Transactions are pooled, validated, and grouped into blocks.
- Nodes exchange votes within their quorum slices until global agreement is reached.
- Once consensus forms across overlapping slices, the block is finalized and added to the ledger.
This approach ensures high throughput, low latency, and exceptional energy efficiency—making Stellar ideal for real-time international payments.

The Role of Lumen (XLM) in the Network
Lumen (XLM) serves as the utility token that keeps the Stellar network secure and functional. While not used for staking or mining, XLM plays several critical roles:
- Spam prevention: Every transaction requires a minimal fee (0.00001 XLM per operation), deterring malicious actors from flooding the network.
- Account minimums: Each account must hold at least 1 XLM to exist on the ledger, ensuring resource accountability.
- Cross-currency bridging: XLM acts as an intermediary asset during multi-currency trades when no direct market exists.
Originally created with a supply of 100 billion XLM, the total was reduced to approximately 50 billion after a community-led vote in 2019 eliminated the inflation mechanism and burned 50 billion tokens. Today, around 28.9 billion XLM are in circulation, with the remainder held by the SDF for ecosystem development and promotional initiatives.
To acquire XLM:
- Purchase it on major cryptocurrency exchanges.
- Swap existing crypto assets via centralized or decentralized platforms.
- Store securely in compatible wallets, including hardware options.

Setting Up a Stellar Validator
Stellar supports open participation—anyone can run a node and contribute to network security and governance. Here’s how to get started:
Step 1: Choose Your Node Type
- Validator: Participates in consensus and helps confirm transactions.
- Full Validator: Maintains a complete history of the ledger by publishing archive snapshots.
Step 2: Meet Hardware Requirements
While no specialized equipment is needed, optimal performance requires:
- 8 vCPUs (Intel Xeon or equivalent)
- 16 GB RAM
- 100 GB NVMe SSD (10,000 IOPS)
Even consumer-grade devices like Raspberry Pi can support lightweight participation.
Step 3: Configure Network Access
Ensure TCP ports are open for peer-to-peer communication to maintain ledger synchronization.
Step 4: Install and Configure Stellar Core
- Download the software for your OS.
- Set the
NETWORK_PASSPHRASEto connect to mainnet or testnet. - Enable validation via configuration flag.
- Define your quorum set—the group of validators your node trusts.
- Configure access to public history archives for data integrity.
- Enable automatic maintenance tasks.
Running a validator empowers you to shape network policies and support decentralized governance.
Key Use Cases of Stellar
Cross-Border Payments & Remittances
Stellar excels in global money transfers, offering:
- Near-instant settlement (under 5 seconds)
- Transaction fees less than a cent
- Support for both fiat and digital currencies
Its partnership with MoneyGram and integration with USDC enable real-time settlements across borders. In 2023, the launch of EURC on Stellar expanded this capability to euro-based transactions.
Businesses using Stellar must comply with KYC, AML, CFT, and sanctions regulations—ensuring safe, legal operations worldwide.

Asset Tokenization
Stellar allows institutions to tokenize real-world assets without relying on complex smart contracts. This simplifies compliance and reduces development overhead.
Supported assets include:
- Fiat-backed stablecoins (e.g., USDC, EURC)
- Money market funds
- Bonds, stocks, and commodities
The Stellar Asset Sandbox lets issuers test tokenization workflows on the testnet before going live.
Tokenization Process:
- Create: Set up an issuing account.
- Duplicate: Create a receiving account.
- Approve: Authorize the recipient to hold/trade the asset.
- Send: Transfer tokens between accounts.
This streamlined process supports regulated financial instruments with built-in controls for freezing or revoking assets.
Decentralized Finance (DeFi)
With full smart contract capabilities introduced in 2024 via Soroban, Stellar now supports advanced DeFi applications such as:
- Lending and borrowing protocols
- Staking mechanisms
- Yield-generating dApps
Built with Rust for security and scalability, Soroban limits developers to a safe subset of language features, reducing vulnerabilities. Developers can also integrate oracles, bridges, and wallets to enhance functionality.
Projects can receive funding through the Stellar Community Fund (SCF), which supports innovation within the ecosystem.
Stellar in CBDCs and Institutional Finance
Stellar’s compliance-first design makes it a top choice for central bank digital currencies (CBDCs) and institutional asset tokenization.
Financial giants like Franklin Templeton and WisdomTree have launched tokenized funds on Stellar, leveraging its:
- Regulatory alignment
- Fast settlement
- Transparent audit trails
Programmable CBDCs issued on Stellar can be restricted by time, location, or use case—enhancing control for governments and employers.

Stellar vs. Ripple: Understanding the Differences
Though both networks focus on payments and share founder Jed McCaleb, their goals diverge significantly.
| Focus Area | Stellar | Ripple |
|---|---|---|
| Target Market | Individuals & financial inclusion | Banks & institutional clients |
| Consensus Mechanism | Stellar Consensus Protocol (SCP) | Ripple Protocol Consensus Algorithm (RPCA) |
| Native Token | XLM (50B max supply) | XRP (100B fixed supply) |
| Inflation Model | Eliminated in 2019 | Deflationary via burning |
While Ripple aims to modernize SWIFT-style banking infrastructure, Stellar builds inclusive financial systems accessible to everyone—even the unbanked.
Can Stellar Achieve Mass Adoption?
Stellar has strong fundamentals: speed, low cost, regulatory readiness, and real-world utility. But mass adoption hinges on overcoming several challenges:
Strengths
- Energy-efficient consensus
- Strategic alliances with Circle and MoneyGram
- Growing DeFi ecosystem via Soroban
- Focus on financial inclusion
Challenges
- Competition from Ripple and newer payment rails
- Perception of centralization due to SDF’s large XLM holdings (~40%)
- Need for broader awareness among consumers and institutions
Despite these hurdles, Stellar’s proven use cases—from humanitarian aid to tokenized securities—show its potential to become a backbone of tomorrow’s digital economy.
