Stellar is a decentralized payment network designed to bridge the gap between blockchain technology and traditional financial systems. Unlike many blockchain platforms that aim to replace existing institutions, Stellar focuses on integration—enabling banks, payment processors, and financial service providers to leverage blockchain for faster, cheaper, and more inclusive cross-border transactions.
Built with scalability, compliance, and interoperability in mind, Stellar supports asset issuance, decentralized exchange, and regulated transaction flows—all while maintaining a high degree of trust and transparency. This makes it particularly appealing to financial institutions seeking innovation without compromising regulatory standards.
Core Architecture of the Stellar Network
The Stellar network consists of two primary components: Stellar Core and Horizon.
- Stellar Core serves as the backbone of the network. It validates transactions using the Stellar Consensus Protocol (SCP)—a unique consensus mechanism that offers fast finality, low energy consumption, and resistance to forks.
- Horizon is an API server that acts as the interface between applications and Stellar Core. Developers use Horizon to submit transactions, query account balances, monitor ledgers, and interact with the network via HTTP requests.
All nodes running Stellar Core form a globally distributed network. Horizon servers connect to these nodes to broadcast transactions and retrieve real-time data. Think of Stellar Core as the engine and Horizon as the dashboard.

Key Concepts in the Stellar Ecosystem
To understand how Stellar enables financial inclusion and interoperability, it’s essential to explore its foundational concepts.
Anchor: The Bridge Between Fiat and Digital Assets
An anchor is a trusted entity that issues assets on the Stellar network—such as USD, EUR, or even commodities—and holds equivalent reserves off-chain. Anchors function similarly to regulated financial institutions like banks or licensed remittance providers.
When an anchor issues a digital representation of a fiat currency (e.g., USDt), users can deposit real-world currency and receive an equivalent balance on the blockchain. These balances are backed by real assets held by the anchor.
Each anchor typically maintains two accounts:
- Issuing Account: Used solely for creating or destroying tokens.
- Base Account: Handles day-to-day operations, including payments and withdrawals.
This dual-account model enhances security and ensures clear separation between asset creation and transaction processing.
For any payment involving anchors, compliance services play a critical role. They verify sender and receiver identities, check sanctions lists, and ensure adherence to anti-money laundering (AML) regulations—making Stellar suitable for regulated finance.
Account: The Foundation of Identity
Every participant in the Stellar network has an account, identified by a public key. Each account stores:
- Balance (in XLM or other assets)
- Sequence number (to prevent replay attacks)
- Trust lines
- Inflation destination
- Associated data entries (key-value pairs)
Accounts must sign every transaction with their private key. The sequence number increases with each transaction, ensuring order and uniqueness—similar to Ethereum’s nonce system.
This structure supports robust identity management while enabling extensibility through custom data storage.
Transaction: Changing the Ledger State
A transaction is the only way to alter the state of the Stellar ledger. It consists of:
- Source account
- Sequence number
- List of operations
- Fee
Each transaction can include multiple operations—such as sending payments, creating accounts, managing offers, or setting options—and all operations within a transaction are atomic: either all succeed or none do.
For example:
{
"source_account": "GA2H...",
"fee": 100,
"seq_num": "123456",
"operations": [
{
"type": "payment",
"destination": "GB4R...",
"asset": "USD",
"amount": "50.00"
}
]
}This design allows complex financial logic to be executed in a single, secure batch.

Asset: Representing Value Beyond XLM
While Lumens (XLM) is Stellar’s native asset used for fees and anti-spam mechanisms, the network supports custom assets issued by anchors.
Every non-native asset has two components:
- Asset code (e.g., USD, EUR)
- Issuer account ID
Holding a tokenized asset means trusting the issuer to redeem it for real-world value. Before receiving an asset, a user must establish a trustline—a permissioned link indicating they accept that issuer’s liability.
Issuers can freeze trustlines if needed—for compliance or fraud prevention—giving them control over their digital ecosystem without sacrificing decentralization at the network level.
Assets must follow standard naming conventions like ISO 4217 (for currencies) or ISIN (for securities), promoting clarity and global recognition.
Distributed Exchange: Built-In Liquidity
Stellar includes a decentralized exchange (DEX) built directly into the protocol. Users can trade any pair of assets through automated market-making logic.
Using the ManageOffer operation, participants can place buy/sell orders on order books. Cross-asset payments (PathPayment) automatically find optimal conversion paths—enabling seamless transfers even when no direct market exists.
For instance, someone can send EUR to a recipient who receives NGN (Nigerian Naira), with conversions handled automatically across multiple liquidity pools.
This native trading capability boosts asset utility and reduces reliance on third-party exchanges.
Inflation: Rewarding Participation
Unlike fixed-supply cryptocurrencies, Stellar implements a modest annual inflation rate of 1%, designed to encourage long-term holding and network participation.
Inflation rewards are distributed weekly to accounts receiving more than 0.05% of the total vote weight from other accounts designating them as inflation destinations.
While optional, this feature promotes decentralization by incentivizing users to support smaller stakeholders rather than concentrating rewards among large holders.
Why Stellar Stands Out in Decentralized Finance
Stellar doesn’t aim to disrupt traditional finance—it aims to upgrade it. By incorporating compliance tools, regulated anchors, and audit-friendly transaction trails, Stellar meets institutional requirements while delivering blockchain benefits: speed, low cost, and global reach.
Use cases include:
- Cross-border remittances
- Central bank digital currency (CBDC) pilots
- Stablecoin issuance
- Microfinance platforms
- Supply chain financing
Its focus on real-world utility over maximal decentralization positions Stellar as a pragmatic solution for financial innovation.

Frequently Asked Questions (FAQ)
Q: What is the native cryptocurrency of the Stellar network?
A: The native token is called Lumen (XLM). It is used to pay transaction fees and prevent spam attacks on the network.
Q: How does Stellar differ from Ethereum?
A: While Ethereum focuses on smart contracts and dApps, Stellar specializes in fast, low-cost payments and asset issuance. It offers built-in decentralized exchange and compliance features suited for financial institutions.
Q: Can anyone issue an asset on Stellar?
A: Technically yes—but only trusted entities should issue assets meant for public use. Issuers must maintain reserves and comply with regulations to gain user trust.
Q: Is Stellar fully decentralized?
A: It uses a hybrid model. The network is decentralized in operation, but asset issuance and compliance rely on trusted anchors, balancing openness with regulatory needs.
Q: How fast are transactions on Stellar?
A: Transactions settle in 3–5 seconds, with very low fees (fractions of a cent), making it ideal for micropayments and high-volume transfers.
Q: What consensus mechanism does Stellar use?
A: The Stellar Consensus Protocol (SCP), which achieves agreement without mining. It’s energy-efficient and provides strong safety guarantees even in partially trusted environments.
