XLM Info
Stellar is a decentralized, open-source blockchain platform for conducting financial operations. It was founded in 2014 by Jed McCaleb, one of the co-founders of Ripple. Stellar utilizes its own consensus protocol called the Stellar Consensus Protocol (SCP), which enables faster and more reliable transaction processing compared to most traditional systems.
The main goal of Stellar is to create an international platform for digital payments that brings together individuals, banks, and payment systems. A crucial aspect of Stellar's functioning is the support for the creation and exchange of “anchor” issuers who process deposits, facilitate asset issuance, and meet the requirements for developers to build products and services using these assets, with a focus on enhancing the end-user experience.
Stellar has its own cryptocurrency called Lumen 
XLMUSD, which is used within the system to pay transaction fees and prevent spam.
