Ripple
Ripple is a real-time gross settlement system, currency exchange, and remittance network created by Ripple Labs. It uses a distributed open-source protocol and supports tokens representing fiat currency, cryptocurrency, commodities, or other units of value. The platform is designed to enable fast, low-cost international payments and settlements for financial institutions.
Developers should learn Ripple when building applications for cross-border payments, remittance services, or financial technology (fintech) solutions that require efficient transaction processing. It is particularly useful for integrating with banking systems, creating digital asset exchanges, or developing blockchain-based payment gateways that prioritize speed and scalability over decentralization.
