Stellar (XLM): A Comprehensive Guide to the Digital Currency
What is Stellar (XLM)?
Stellar (XLM) is an open-source, decentralized payment protocol that enables fast, cross-border transactions between any pair of currencies. Founded in 2014 by Jed McCaleb (co-founder of Ripple) and Joyce Kim, Stellar aims to connect financial institutions, payment systems, and individuals globally. The network's native digital currency, the Lumen (XLM), serves as the bridge currency in transactions and helps prevent spam on the network.
Unlike many cryptocurrencies that focus primarily on being alternatives to traditional money, Stellar was designed with a mission to expand financial access and inclusion worldwide, particularly for underbanked populations. The Stellar network can handle exchanges between fiat currencies, cryptocurrencies, and other forms of value transfer with minimal fees.
How Does Stellar (XLM) Work?
Stellar operates on a unique consensus protocol called the Stellar Consensus Protocol (SCP). Unlike traditional proof-of-work (PoW) systems used by Bitcoin or proof-of-stake (PoS) systems used by Ethereum 2.0, Stellar employs a federated Byzantine agreement model. Here's how it works:
Stellar Consensus Protocol (SCP)
The SCP allows nodes on the Stellar network to reach consensus without requiring approval from the entire network. Each node selects a set of trusted nodes (called a "quorum slice"), and when a sufficient number of these trusted nodes agree on a transaction, consensus is reached. This makes Stellar incredibly efficient, with transactions confirming in 3-5 seconds and the capability to handle thousands of transactions per second.
Anchors and Bridges
Anchors are entities (like banks or payment processors) that people trust to hold their deposits and issue credits into the Stellar network. These anchors serve as bridges between different currencies and the Stellar network. When you want to send euros to someone who wants to receive dollars, the Stellar network automatically finds the best conversion path using XLM as an intermediary if needed.
Distributed Exchange
Stellar has a built-in decentralized exchange where users can trade any asset pair, creating a global marketplace. This allows for seamless currency conversion without the need for traditional forex markets.
Does Stellar (XLM) Offer Staking and Mining?
Stellar (XLM) does not offer traditional mining or staking mechanisms like many other cryptocurrencies. Here's why:
No Mining
Since Stellar doesn't use Proof-of-Work, there is no mining process for XLM. All Lumens were pre-mined at the network's inception, and no new coins are created through mining activities. This makes Stellar significantly more environmentally friendly than mining-based cryptocurrencies.
No Traditional Staking
Stellar doesn't employ a Proof-of-Stake mechanism, so there isn't a traditional staking system where token holders lock up their assets to earn rewards for validating transactions. However, some centralized exchanges and platforms may offer "staking-like" services where users can earn interest on their XLM holdings, but these aren't native to the Stellar protocol.
Inflation (Historical Note)
Historically, Stellar had an inflation mechanism that would create new XLM at a rate of 1% annually, with these new tokens distributed to addresses that received votes from XLM holders. However, in October 2019, the Stellar Development Foundation (SDF) removed this inflation mechanism through a network upgrade, meaning no new XLM are being created.
What is Stellar (XLM) Used For?
Stellar (XLM) serves multiple purposes within and beyond the Stellar network:
Network Fees
Every transaction on the Stellar network requires a small fee (currently 0.00001 XLM) to prevent spam attacks. These fees are not distributed to any participant but are simply removed from the supply.
Facilitating Cross-Border Payments
XLM acts as a bridge currency, facilitating exchanges between different currencies when no direct market exists. This allows for quick and low-cost international money transfers.
Minimum Account Balance
Each Stellar account must maintain a minimum balance of 1 XLM to remain active, which helps prevent network bloat.
Tokenization Platform
The Stellar network supports the issuance of custom tokens, enabling businesses and organizations to create digital representations of various assets, including fiat currencies, commodities, or even loyalty points.
Financial Inclusion
A core mission of Stellar is to provide financial services to underbanked populations globally. XLM and the Stellar network enable access to banking services for those who may not have access to traditional banking infrastructure.
Distribution of XLM When Launched
When Stellar launched in 2014, the initial supply was 100 billion Lumens (then called "Stellars"). The distribution strategy was designed to promote adoption and development:
Initial Distribution
- 5% of the initial supply was used to fund Stellar Development Foundation operations
- 50% was allocated for the direct sign-up program, where individuals could receive free XLM by signing up with a unique email
- 25% was allocated to partners through the partnership program
- 20% was allocated to Bitcoin and Ripple (XRP) holders through a giveaway
Supply Reduction
In November 2019, the Stellar Development Foundation (SDF) made a significant announcement to reduce the overall XLM supply by burning approximately 55 billion XLM tokens. This reduced the total supply from about 105 billion to 50 billion XLM, with around 20 billion in circulation and the rest held by the SDF for development and promotional efforts.
Current Distribution
Currently, the approximately 50 billion total supply of XLM is divided between:
- Circulating supply in public hands
- SDF's operating fund
- SDF's Direct Development Fund for ecosystem support and grants
Other Important Information About Stellar (XLM)
Partnerships
Stellar has formed significant partnerships with companies like IBM, which used the Stellar network for its World Wire cross-border payment system. The Stellar Development Foundation has also partnered with financial institutions globally to expand the use of the network for remittances and international payments.
Smart Contracts
While Stellar isn't primarily designed for complex smart contracts like Ethereum, it does support simple smart contracts in the form of multi-signature accounts, atomic swaps, time-bounded transactions, and sequence numbers.
Soroban
In 2023, Stellar introduced Soroban, a new smart contract platform designed to extend Stellar's capabilities while maintaining its focus on efficiency and scalability for financial applications. This development represents a significant evolution for the network.
Non-Profit Foundation
Unlike many cryptocurrency projects, Stellar is overseen by the non-profit Stellar Development Foundation, which focuses on network growth, ecosystem support, and regulatory compliance rather than profit maximization.
