This chapter introduces Ripple as a blockchain-inspired credit network designed for fast, low-cost cross-border payments. You will learn about its origins, architecture, and how it differs from Bitcoin and Ethereum, particularly through its validator-based consensus and account model. You will explore XRP's tokenomics, the structure of the XRP Ledger, and how Ripple supports features like trust lines, path-based settlements, escrows, and a built-in decentralized exchange. The chapter also explains how Ripple enforces finality, handles fees, and enables institutional-grade transaction tagging, while addressing regulatory and security mechanisms unique to the network.
