Stellar is an open-source blockchain platform designed to enhance financial inclusion and streamline cross-border payments. Developed by the nonprofit Stellar Development Foundation (SDF), it enables fast, low-cost transactions for individuals, small businesses, and institutions. At its core, Stellar bridges traditional financial systems with digital assets, making global money transfers more accessible—especially in underserved markets.
The network’s native cryptocurrency, XLM (Lumens), plays a vital role in transaction efficiency, acting as a bridge asset for seamless currency conversions and maintaining network integrity through minimal fees and account requirements.
A Quick Overview of Stellar
Stellar operates as a decentralized financial network where users can issue, transfer, and trade digital representations of any asset—fiat currencies, cryptocurrencies, or even commodities. Its primary mission is to connect disparate financial systems, enabling interoperability between banks, payment providers, and individuals across borders.
XLM, the native token, facilitates quick settlement of transactions and helps prevent spam on the network. It also serves as a liquidity bridge, allowing users to convert between different currencies without needing direct trading pairs. This makes Stellar particularly effective for remittances, micropayments, and asset issuance.
The platform supports a wide range of financial services without relying on central intermediaries, empowering both individuals and institutions to build inclusive financial solutions.
The Founding Team Behind Stellar
Stellar was co-founded in 2014 by Jed McCaleb and Joyce Kim under the umbrella of the Stellar Development Foundation. McCaleb is a well-known figure in the blockchain space—he previously co-founded Ripple Labs but left due to philosophical differences over decentralization and control.
His vision for Stellar emphasized greater openness and accessibility, particularly for unbanked populations. Other key contributors include:
- Nicolas Barry, Chief Technology Officer
- David Mazières, Stanford computer science professor and lead architect of the Stellar Consensus Protocol (SCP)
This blend of technical expertise and social mission has helped shape Stellar into a scalable, energy-efficient, and purpose-driven blockchain network.
Understanding the Stellar Consensus Protocol (SCP)
One of Stellar’s most innovative features is its Stellar Consensus Protocol (SCP)—a unique consensus mechanism that enables fast, secure, and low-energy transactions without proof-of-work mining.
Unlike Bitcoin’s energy-intensive PoW or Ripple’s centralized validator model, SCP uses a Federated Byzantine Agreement (FBA) system. This allows nodes to independently choose which other nodes they trust, forming “quorum slices” that collectively reach consensus.

Key advantages of SCP include:
- High scalability: Processes over 1,000 transactions per second
- Low latency: Final settlement in 3–5 seconds
- Energy efficiency: No computational mining required
- Decentralized governance: Open participation for validators
This design ensures resilience against malicious actors while maintaining speed and accessibility—making it ideal for real-world financial applications.
The Dual Structure of SCP: Nomination and Ballot Protocols
The SCP operates through two coordinated sub-protocols:
1. Nomination Protocol
In each consensus round, nodes propose candidate values (e.g., transaction sets). Through iterative communication, they converge on a shared set of transactions to consider.
2. Ballot Protocol
Once nominations are finalized, nodes enter the ballot phase. Here, they vote to either commit or abort the proposed block. A value becomes final only when a supermajority agrees across overlapping quorums.
This dual-layer approach enhances security and fault tolerance, ensuring consistency even if some nodes behave unpredictably.
Quorums and Quorum Slices: The Backbone of Trust
In SCP, quorums are groups of nodes sufficient to reach agreement. However, instead of requiring universal agreement like traditional Byzantine systems, SCP allows nodes to define their own quorum slices—small trusted subsets that influence their decisions.
For example:
- Node A trusts Nodes B and C → forms a slice
- Node B trusts Nodes C and D → forms another slice
- Overlapping slices create interconnected quorums
Crucially:
- Quorum intersection prevents split decisions (forks)
- Disjoint quorums risk conflicting outcomes and must be avoided
- Trust is configured locally in node settings, enabling flexible yet secure decentralization
This model supports open participation while preserving network coherence—a major step forward in distributed consensus design.
Stellar vs. Ripple: Key Differences
Though both projects originated from Jed McCaleb and target cross-border payments, Stellar and Ripple differ significantly in philosophy and execution.
| Feature | Ripple | Stellar |
|---|---|---|
| Target Audience | Banks & financial institutions | Individuals & small businesses |
| Primary Use Case | Institutional settlements | Financial inclusion & remittances |
| Consensus Mechanism | RPCA (permissioned) | SCP (open, federated) |
| Decentralization Level | Lower (controlled validators) | Higher (open validator access) |
| Native Token | XRP | XLM (Lumens) |
| Codebase | Closed-source | Open-source |
| Foundation | Ripple Labs | Stellar Development Foundation |
While Ripple focuses on transforming banking infrastructure, Stellar aims to democratize access to financial tools globally.
Stellar vs. Bitcoin: A Modern Alternative
Stellar offers a stark contrast to Bitcoin in several key areas:
| Feature | Stellar | Bitcoin |
|---|---|---|
| Transaction Speed | 3–5 seconds | ~10 minutes |
| Fees | 0.00001 XLM (~$0.000001) | Variable, often high during congestion |
| Energy Use | Extremely low | High (due to PoW mining) |
| Scalability | >1,000 TPS | ~7 TPS |
| Smart Contracts | Limited support | No native support |
| Supply Cap | 50 billion XLM | 21 million BTC |
Stellar prioritizes utility and accessibility over store-of-value functions, positioning itself as a practical layer for everyday transactions rather than digital gold.
Real-World Adoption: Who Uses Stellar?
Stellar has forged strategic partnerships with major organizations aiming to improve global financial access:
- IBM World Wire: Utilizes Stellar to enable instant cross-border settlements across multiple currencies using XLM as a bridge asset.
- Tempo: Acts as a Euro anchor on the Stellar network, facilitating fiat on/off ramps.
- SatoshiPay: Leverages XLM for microtransactions in digital content platforms.
- Flutterwave: Integrates Stellar for faster African remittances.
- HTC Exodus: Supports XLM in its blockchain smartphone wallet.
These collaborations highlight Stellar’s growing role in real-world finance—particularly in emerging economies where traditional banking infrastructure is lacking.

How to Use the Stellar Network
Using Stellar involves three core components: wallets, anchors, and XLM.
Anchors: Bridging Fiat and Digital Assets
Anchors are trusted entities on the Stellar network that hold deposits (like USD or EUR) and issue equivalent digital credits. For example:
- Deposit $100 at Anchor A → Receive 100 USDt tokens on Stellar
- Send USDt to another user → They can redeem it for cash via another anchor
Anchors maintain trust by backing issued tokens 1:1 and enabling withdrawals. They are essential for connecting fiat systems with blockchain efficiency.
Transaction Requirements
To interact with the network:
- Pay a tiny fee: 0.00001 XLM per operation
- Maintain minimum balance: 1 XLM per account
These measures deter spam while keeping costs negligible for users.
Understanding XLM: The Role of Lumens
XLM (Lumens) is not just a cryptocurrency—it's a functional tool within the Stellar ecosystem.
Core Functions of XLM
- Bridge currency: Enables fast conversions between different assets (e.g., EUR → XLM → NGN)
- Spam prevention: Small transaction fees discourage network abuse
- Account reserves: Minimum balance requirement protects against account bloat
Tokenomics Overview
- Initial supply: 100 billion XLM
- In 2019, 50 billion were burned → Fixed max supply: 50 billion
- Circulating supply: ~20 billion (as of 2025)
- Held by SDF for ecosystem grants, partnerships, and development
As of 2025, XLM ranks among the top 30 cryptocurrencies by market cap, reflecting sustained interest and utility.
