Stellar (XLM) is a prominent public blockchain project that functions as an open network with no barriers to entry. You might wonder - what exactly does "openness" mean in a public blockchain context? Essentially, it refers to the absence of "locked gates" where anyone can join and participate without relying on centralized authorities. These characteristics give Stellar significant practical advantages when compared to private or consortium blockchains.
What Exactly is a Public Blockchain?
Public blockchains serve as the foundation of all blockchain technology. A Public Blockchain is a network where anyone can:
- Join at any time
- Send transactions
- Read information
...without requiring approval from centralized institutions. Imagine an open community where every participant can contribute, oversee operations, and access transparent information. By design, public blockchains embody decentralization, transparency, and openness - their core competitive advantages.
Key Features of Stellar as a Public Blockchain
Stellar Lumens (XLM) serves as the native currency of the Stellar Network, functioning like a "universal token" within this ecosystem. The network itself is an open-source protocol designed to bridge digital currencies and fiat systems. Think of it like currency exchange shops in international airports that help avoid cumbersome conversion fees and long waits.
Stellar's public blockchain characteristics stem from its design philosophy:
✔️ Open Access: No restrictions or barriers imposed by centralized entities
✔️ Decentralization: Network data isn't controlled by any single entity but maintained collectively via distributed ledger technology
✔️ Scalability: Supports diverse applications from cross-border payments to customized dApp development
✔️ Low-Cost Transactions: Unique consensus mechanism and efficient validation algorithms keep fees minimal while maintaining speed

Public vs Private vs Consortium Blockchains
While public blockchains like Stellar offer clear advantages, private and consortium chains serve different purposes:
| Feature | Public (Stellar) | Private | Consortium |
|---|---|---|---|
| Access | Permissionless | Permissioned | Semi-permissioned |
| Speed | Moderate | Fastest | Fast |
| Decentralization | High | Low | Medium |
| Use Cases | Global payments | Internal systems | Inter-org collaboration |
Private chains typically appeal to enterprises for internal systems - like a corporate intranet with strictly controlled write permissions. Consortium chains resemble multi-organization data sharing platforms where members jointly control node access.
Technical Advantages of Stellar Network
Stellar employs several innovative technologies:
🔹 Stellar Consensus Protocol (SCP): Combines Federated Byzantine Fault Tolerance (FBFT) with other algorithms to optimize efficiency, security, and scalability
🔹 Distributed Hash Tables (DHT) & Merkle Trees: Ensure transaction security and integrity through digital "fingerprinting"
🔹 Enhanced Performance: Upgraded from Ripple's technology with improved node efficiency and reduced resource requirements
Transaction speed and cost efficiency make Stellar particularly attractive for cross-border payments, often processing transactions faster than traditional systems at minimal fees.
Practical Applications of Stellar Network
Stellar excels in multiple use cases:
🌍 Cross-Border Payments: Fast, low-cost international money transfers
💎 Asset Tokenization: Digitizing stocks, bonds, real estate, and other assets
🛡️ Digital Identity Management: Decentralized identity verification protecting user privacy
📱 dApp Development: Supports decentralized exchanges, lending platforms, and other applications
FAQ: Common Questions About Stellar
Q: Is Stellar centralized or decentralized?
A: While more decentralized than private chains, Stellar is less decentralized than Bitcoin due to its consensus model. However, it maintains sufficient decentralization for most practical purposes.
Q: How does Stellar differ from Ripple?
A: Both originated from similar concepts, but Stellar focuses more on financial inclusion for individuals, while Ripple targets institutional payment solutions.
Q: What makes Stellar's transaction fees so low?
A: Its efficient consensus mechanism requires minimal computational resources compared to proof-of-work systems, keeping costs down.
Q: Can businesses build private applications on Stellar?
A: Yes, organizations can develop permissioned applications while still benefiting from Stellar's public infrastructure for settlement.
Q: How does Stellar prevent network spam?
A: Accounts require small XLM balances, and transactions incur minimal fees - enough to deter spam without excluding legitimate users.
Q: Is Stellar environmentally friendly?
A: Compared to proof-of-work blockchains, Stellar's consensus mechanism is far more energy efficient, making it a greener alternative.
Investment Considerations
When evaluating Stellar or any blockchain project:
- Assess your risk tolerance and investment goals thoroughly
