Stellar is a decentralized blockchain network designed to enable fast, low-cost cross-border payments and financial inclusion for underserved populations worldwide. Built with the mission of creating an open, interoperable financial infrastructure, Stellar facilitates seamless transactions between different currencies—both fiat and digital—making it a powerful tool for remittances, banking, and global finance.
At the heart of the network is Lumens (XLM), the native cryptocurrency that powers transactions and secures the ecosystem. Unlike traditional blockchains that rely on energy-intensive consensus mechanisms like Proof of Work or Proof of Stake, Stellar uses its own innovative Stellar Consensus Protocol (SCP), enabling rapid transaction finality with minimal fees.
Who Created Stellar?
Stellar was founded in 2014 by Jed McCaleb, a prominent figure in the cryptocurrency world known for co-creating Ripple (XRP) and previously launching the Mt. Gox exchange. Seeking to build a more inclusive financial system, McCaleb established the Stellar Development Foundation (SDF), a non-profit organization tasked with guiding the network’s development and adoption.
The foundation received initial funding through a $3 million loan from Stripe, marking its only formal investment round. In 2015, 100 billion XLM tokens were created, distributed as follows:
- 52% via public airdrops to increase accessibility
- 46% allocated to the foundation and early contributors
- 2% to Stripe as part of their support
This equitable distribution model underscored Stellar’s commitment to decentralization and broad user participation.

How Does Stellar Work?
The Stellar Consensus Protocol (SCP)
Stellar operates using the Stellar Consensus Protocol (SCP), a unique consensus mechanism derived from the Federated Byzantine Agreement (FBA). Unlike traditional models that depend on mining or staking rewards, SCP achieves consensus through trust-based node networks—without requiring financial incentives.
Key advantages of SCP include:
- Decentralized control: Any individual or institution can run a validator node.
- Low latency: Transactions settle in 3–5 seconds.
- Flexible trust: Each node selects which other nodes it trusts; groups of trusted nodes form quorum slices.
- Asymptotic security: Cryptographic signatures and hash functions protect data integrity and prevent tampering.
Running a node requires only the free Stellar Core software, which has modest hardware requirements. This accessibility encourages widespread participation and strengthens network resilience.
Because there's no mining or staking involved, XLM isn't used to secure the network through economic penalties—but rather to prevent spam and maintain account activity.
Anchors: Bridging Fiat and Digital Currencies
One of Stellar’s most innovative features is its use of anchors—trusted entities such as banks or payment providers that issue credit on the Stellar network backed by real-world assets like USD or EUR.
Anchors allow users to:
- Deposit fiat currency and receive equivalent digital credits on the blockchain
- Send those credits instantly across borders
- Withdraw funds in local currency via another anchor at the destination
This creates a seamless bridge between traditional banking systems and decentralized finance. For example, someone in the U.S. can deposit USD with an American anchor, send it to a recipient in Kenya, who then cashes out via a local African anchor in Kenyan shillings—all within minutes and at minimal cost.
This interoperability makes Stellar ideal for remittances, micropayments, and cross-border commerce.

Stellar vs Ripple: Key Differences
While both Stellar and Ripple were co-founded by Jed McCaleb and share similar goals—accelerating cross-border payments—they differ significantly in structure, purpose, and governance.
| Aspect | Stellar | Ripple |
|---|---|---|
| Governance | Non-profit foundation (SDF) | For-profit private company |
| Mission | Financial inclusion for unbanked populations | Integration with existing financial institutions |
| Codebase | Independent, open-source platform | Proprietary RippleNet protocol |
| Consensus | Stellar Consensus Protocol (SCP) | Ripple Protocol Consensus Algorithm (RPCA) |
| Token Utility | Network fees, anti-spam, multi-currency exchange | Primarily used for liquidity in XRP Ledger |
Stellar supports smart contracts and decentralized applications, allowing developers to build financial tools directly on its network. Ripple, by contrast, functions mainly as a payments rail for banks and institutions.
These distinctions reflect differing philosophies: Stellar emphasizes openness and accessibility, while Ripple focuses on enterprise adoption.
What Is the Role of XLM?
Lumens (XLM) serve several critical functions within the Stellar ecosystem:
- Transaction Fees: Every operation on the network incurs a minimal fee of 0.00001 XLM, designed not for profit but to deter spam attacks.
- Minimum Balance Requirement: To prevent dormant accounts from bloating the ledger, each wallet must hold at least 1 XLM to remain active.
- Bridge Currency: When converting between two incompatible assets (e.g., USD to EUR), XLM acts as an intermediary currency during atomic swaps.
Notably, the total supply of XLM is capped at 50 billion tokens, ensuring scarcity and long-term predictability. This fixed supply enhances transparency and aligns with sound monetary principles.
Partnership with MoneyGram: Real-World Adoption
In 2021, Stellar solidified its real-world utility through a strategic partnership with MoneyGram, one of the largest money transfer companies globally.
This integration enables users to:
- Send stablecoins (like USDC) over the Stellar network
- Convert them into fiat currency
- Cash out at any of MoneyGram’s thousands of physical locations worldwide
This fusion of blockchain efficiency with traditional financial infrastructure exemplifies Stellar’s vision: a hybrid system where digital assets enhance—not replace—existing services.
It also demonstrates how blockchain can reduce remittance costs (which average around 6–7% globally) while increasing speed and transparency.
Why Choose Stellar?
Stellar stands out in the crowded blockchain space due to its:
- Ultra-low transaction costs
- High throughput (thousands of transactions per second)
- Energy-efficient consensus mechanism
- Strong focus on financial inclusion
- Interoperability with fiat currencies via anchors
Developers also benefit from Stellar’s robust SDKs and developer tools, which simplify building wallets, payment gateways, and DeFi applications.
Organizations including IBM and Flutterwave have already built solutions on Stellar, validating its enterprise-grade reliability.
Frequently Asked Questions (FAQ)
