Question 1

What is the Stellar Consensus Protocol (SCP)?

Accepted Answer

SCP is Stellar's unique consensus mechanism, based on the Federated Byzantine Agreement (FBA). It allows nodes to agree on the validity of transactions through trusted groups, or quorum slices, rather than competing for computational power or staking tokens. This approach delivers fast finality, high security, and energy efficiency, making it ideal for global financial applications.

Question 2

Who created Stellar?

Accepted Answer

Stellar was co-founded in 2014 by Jed McCaleb, previously a co-founder of Ripple, and Joyce Kim. Together they launched the Stellar Development Foundation (SDF), a nonprofit organization that supports the network's growth and development with the goal of promoting financial inclusion worldwide.

Question 3

What is Soroban, and how does it enhance Stellar?

Accepted Answer

Soroban is Stellar's smart contract platform introduced with Protocol 20 in 2024. Built with Rust and WebAssembly (WASM), it enables developers to build secure and efficient decentralized applications (dApps). Soroban supports complex financial use cases - such as lending, tokenized assets, and decentralized exchanges - while maintaining Stellar's hallmark speed and low costs.

Question 4

How does Stellar enable cross-border payments?

Accepted Answer

Stellar facilitates near-instant, low-cost global transfers by converting assets through XLM as a bridge currency. The network's built-in decentralized exchange (DEX) automatically finds the best path between any two currencies, allowing users to send money across borders in seconds without relying on traditional intermediaries.

Question 5

What makes Stellar different from Ripple (XRP)?

Accepted Answer

Although both focus on payments, Stellar and Ripple are distinct networks. Stellar is open-source, community-governed, and designed for inclusivity and accessibility, while Ripple primarily serves banks through a for-profit model. Stellar's SCP also operates differently from Ripple's consensus system, relying on decentralized trust rather than validator lists managed by a single entity.

Question 6

How secure is the Stellar network?

Accepted Answer

Stellar's design prioritizes security through SCP, which prevents double-spending and malicious attacks even if some nodes misbehave. Soroban enhances security further through Rust's memory safety, non-reentrancy architecture, and an authorization-required model, reducing common smart contract vulnerabilities.

Question 7

What role does XLM play in the ecosystem?

Accepted Answer

XLM is used to pay transaction fees, maintain minimum account balances, and serve as a bridge currency for multi-currency payments. This structure prevents spam attacks, keeps the network efficient, and enables seamless currency conversions between fiat and digital assets. Each account must maintain a minimum balance of XLM to remain active on the network.

Question 8

How does Stellar support real-world asset (RWA) tokenization?

Accepted Answer

Stellar's native asset-issuance framework lets institutions create tokens representing fiat currencies, securities, or funds directly on-chain. Features like issuer authorization, freeze and clawback controls, and built-in compliance tools make it suitable for regulated assets. Institutions such as Franklin Templeton and WisdomTree have issued tokenized assets on Stellar's network.

Question 9

What are Stellar Anchors and why are they important?

Accepted Answer

Anchors are entities that connect Stellar to traditional financial systems by issuing on-chain tokens backed by off-chain assets like fiat currencies. They enable seamless on/off ramps, allowing users to deposit or withdraw local currency while using blockchain-based services, thus bridging the gap between crypto and real-world money.

Question 10

How fast and affordable are Stellar transactions?

Accepted Answer

Transactions on Stellar typically settle within 3–5 seconds and cost a fraction of a cent (around 0.00001 XLM). This speed and efficiency make the network ideal for micropayments, remittances, and large-scale institutional use cases.

Question 11

How is Stellar environmentally sustainable?

Accepted Answer

Unlike Proof-of-Work blockchains that rely on energy-intensive mining, Stellar's consensus uses minimal electricity. The SCP protocol achieves network security without competition or resource-heavy validation, making it one of the most environmentally efficient blockchains in operation.

Question 12

What industries or companies use Stellar today?

Accepted Answer

Stellar's technology is used by major financial institutions and fintech companies worldwide, including MoneyGram, Franklin Templeton, and Circle, and in humanitarian projects such as UNHCR's blockchain-based aid programs.

Question 13

Can developers build DeFi apps on Stellar?

Accepted Answer

Yes. With Soroban, developers can create decentralized exchanges, lending markets, yield protocols, and asset-management platforms natively on Stellar. Soroban's purpose-built financial design allows for predictable fees, scalability, and secure execution optimized for financial applications.

Question 14

How can users get XLM?

Accepted Answer

Users can buy, sell, and trade XLM on most major cryptocurrency exchanges or directly within self-custody wallets like the Bitcoin.com Wallet. XLM is widely available globally and can be stored in any wallet that supports the Stellar network.

Question 15

What's next for Stellar's roadmap?

Accepted Answer

Stellar's development focuses on expanding Soroban adoption, enhancing cross-border payments, and scaling real-world asset tokenization. The Stellar Development Foundation continues to strengthen partnerships with global financial institutions to bridge traditional banking and decentralized finance on a single, interoperable network.
