Stellar (XLM) Cryptocurrency: Comprehensive Overview
Core Technology and Blockchain Architecture
Stellar (XLM) is an open-source blockchain network designed to facilitate fast, low-cost international payments and asset tokenization by connecting traditional finance with decentralized systems. Stellar is an open-source protocol for exchanging money or tokens using the Stellar Consensus Protocol.
The platform's source code is hosted on GitHub. Servers run a software implementation of the protocol, and use the Internet to connect to and communicate with other Stellar servers. Each server stores a ledger of all the accounts in the network.
Consensus Mechanism and Network Security
Stellar uses its unique Stellar Consensus Protocol (SCP), a federated Byzantine agreement system where known validators achieve consensus without mining or staking. SCP is based on a model called the Federated Byzantine Agreement (FBA). In this model, each validator chooses a group of trusted peers, known as its quorum set. Consensus is reached when enough overlap exists across these sets, allowing nodes to agree on which transactions to include.
This makes it highly energy-efficient. These nodes work together to validate transactions, decide their order, and update the shared ledger roughly every five to seven seconds. Unlike other Proof-of-Stake mechanisms, network validators are not financially incentivized to process transactions.
Founding Team and Project History
In 2014, Jed McCaleb, founder of Mt. Gox and co-founder of Ripple, launched the network system Stellar with former lawyer Joyce Kim. The nonprofit Stellar Development Foundation was created in collaboration with Stripe CEO Patrick Collison and the project officially launched that July. Stellar received $3 million in seed funding from Stripe.
The new algorithm used SCP, a cryptocurrency protocol created by Stanford professor David Mazières. The Stellar Development Foundation released an upgraded protocol with a new consensus algorithm in April 2015 which went live in November 2015.
Lightyear.io, a for-profit entity of Stellar, was launched in May 2017 as the commercial arm of the company.
Primary Use Cases and Real-World Applications
Stellar solves fragmented global payments by acting as a bridge between financial institutions, payment systems, and individuals. It enables near-instant, low-cost cross-border transactions. It enables near-instant, low-cost cross-border transactions (3-5 second finality) and currency conversions, targeting financial inclusion in underserved regions.
Stellar supports stablecoins and real-world assets (RWAs) like tokenized funds. The network supports Soroban, a Rust-based smart contract platform optimized for financial applications with sub-5-second settlement and predictable fees.
Stellar specializes in real-world asset (RWA) tokenization, hosting $400B+ in transactions for institutions like Franklin Templeton and WisdomTree. Its built-in DEX allows seamless asset swaps, while compliance tools and ISO 20022 alignment appeal to regulated entities.
Anchors (trusted entities like banks) issue digital representations of assets (e.g., USD, EUR), which users trade via Stellar's built-in decentralized exchange (DEX).
Tokenomics: Supply and Distribution
Total Supply and Burn Event
When Stellar launched in 2014, 100 billion XLM tokens were created at genesis. For the first few years, the supply of tokens increased by 1% annually through an inflation mechanism, but this feature was removed by community vote in 2019.
Later that year, the SDF decided to burn approximately 55 billion tokens and reduce the total supply to around 50 billion, with no new tokens to be created in the future. On November 4, 2019, a major supply reduction occurred: ~55 billion XLM (over 50% of supply) were burned, reducing total supply to ~50 billion XLM.
Circulating Supply and Current Distribution
As of August 2025, around 31.3 billion tokens are in public circulation, while the SDF holds around 18.4 billion tokens to support the network's development and ecosystem growth.
Inflation and Deflation Mechanics
Unlike many other blockchains, the native network currency is not created through mining- all XLM that has ever existed and will ever exist was created when the Stellar network went live. Initially, Stellar implemented a 1% annual inflation mechanism that distributed new XLM to accounts based on community votes. However, after extensive debate among stakeholders, this inflation model was officially retired in October 2019, transitioning XLM to a fixed supply asset.
Stellar's deflationary mechanism operates through a systematic 1% transaction burn, creating continuous downward pressure on the total circulating supply. This tokenomics design distinguishes XLM from inflationary models by removing tokens from circulation permanently with each transaction processed on the network.
XLM Token Utility
Lumens (XLM) are the native currency of the Stellar network. The lumen is the only token that doesn't require an issuer or trustline. They are used to pay all transaction fees, fund rent, and to cover minimum balance requirements on the network.
The Stellar protocol uses the XLM token, which serves as a transactional currency and a bridge between currencies. Lumens are also used as an anti-spam mechanism to prevent the network from being flooded with unwanted transactions.
Key Partnerships and Ecosystem Integrations
Partnerships with Visa, MoneyGram, and UNDP enable stablecoin settlements and humanitarian aid distribution. In October 2017, Stellar partnered with IBM and KlickEx to facilitate cross-border transactions in the South Pacific region. The cross-border payment system developed by IBM includes partnerships with banks in the area.
In 2021, Franklin Templeton launched the first tokenised US mutual fund using Stellar. In October 2024, Stellar announced partnerships with Mastercard and Paxos.
On Oct. 15, 2020, the SDF announced that Stellar will be an official USD Coin (USDC) blockchain. USDC is a stablecoin issued by Circle. This led to the October 2021 collaboration between the SDF and MoneyGram, a global financial technology company, transforming settlement flows by facilitating near-instant settlement in USDC.
Stellar has partnered with leading companies such as Deloitte and American Express. These partnerships leverage Stellar's technology to enhance their services and reach a wider audience.
This insight led to the development of the Stellar Anchor Network, an unmatched system of over 450,000 cash-to-crypto ramp locations worldwide that connects blockchain technology with existing banking systems and payment rails. This vast network—spanning 180+ countries—creates a critical infrastructure layer that traditional financial institutions can leverage to offer blockchain-based services on a single, seamless platform.
Competitive Advantages and Unique Value Proposition
Stellar's unique Stellar Consensus Protocol (SCP) offers a more energy-efficient, scalable, and fast alternative to traditional blockchain mechanisms. With Soroban live on mainnet, Stellar now supports smart-contract applications for programmable payouts, FX, and financial workflows—while retaining low fees and a payments-first design. Ripple's focus remains primarily on high-speed settlement rather than a broad smart contract platform, making Stellar a more versatile choice for developers building decentralized applications (dApps) on top of the payment layer.
Stellar's combination of USDC + MoneyGram cash access is a unique retail-grade distribution model that shortens the distance between digital dollars and real-world use. Ripple has recently entered the stablecoin space with plans to issue its own, but Stellar's first-mover advantage with a major, regulated stablecoin like USDC is a significant edge.
Unlike proof-of-work chains, Stellar uses a unique consensus protocol (the Stellar Consensus Protocol - SCP) that allows transactions to settle in 3-5 seconds with fees that are a fraction of a cent. This efficiency enables not just large transfers but also micro-transactions and frequent settlement cycles that are impractical on other networks.
Current Development Activity and Roadmap Highlights
