Stellar is an open-source, decentralized protocol designed to facilitate cross-border transactions and improve financial inclusivity for individuals and institutions. It was created in 2014 by Jed McCaleb, one of the co-founders of Ripple. The Stellar network aims to connect banks, payment systems, and individuals to speed up and reduce the cost of transferring money worldwide—particularly in developing countries where traditional banking infrastructure may be lacking.

Stellar operates on its own blockchain called the Stellar Consensus Protocol (SCP), which innovatively addresses the challenges of scalability and decentralization.

Stellar stands out as a robust and versatile technology designed to transform the global financial landscape. Its emphasis on speed, affordability, and accessibility positions it as a valuable platform in an increasingly interconnected world. By leveraging blockchain technology and a unique consensus mechanism, Stellar is not only streamlining cross-border transactions but also opening doors to financial inclusivity, providing opportunities for millions who have been left behind by traditional banking systems. As the network continues to evolve, it could play a pivotal role in the future of money and finance, particularly in emerging markets.

Components of the Stellar Ecosystem

1. Network Participants:

   • Stellar Nodes: These are the servers run by individuals or organizations that maintain the network and validate transactions.
   • Anchors: Institutions that facilitate the exchange of fiat currency (like banks) and issue tokens on the Stellar network.
   • Users: Individuals or organizations that use the Stellar network to transact, often through wallets or apps.

2. Stellar Consensus Protocol:

   • SCP is a consensus algorithm designed for speed and scalability. Instead of relying on resource-intensive mining (as seen in Bitcoin), Stellar nodes participate in a mutual agreement on the next valid state of the ledger.
   • Nodes choose a small number of other nodes they trust, and this “quorum” can vote to validate transactions. This process is efficient, achieving consensus in mere seconds.

3. Transaction Process:

   • A user initiates a transaction (e.g., sending money) through their wallet.
   • The transaction is broadcast to the Stellar network, where it is picked up by the nodes.
   • Nodes validate the transaction through SCP and update the ledger accordingly.
   • Once confirmed, the transaction is completed, and funds are credited to the recipient's account instantly—regardless of geographic location or currency.

4. Lumens as a Transaction Medium:

   • When converting between currencies, Stellar may utilize Lumens to facilitate these exchanges, even if the original sender and the final recipient do not hold any Lumens themselves. The framework ensures a seamless, fast transaction process.
