What is Ripple?

Ripple is a network of computers which use the Ripple consensus algorithm to atomically settle and record transactions on a secure distributed database, the Ripple Consensus Ledger (RCL). Because of its distributed nature, the RCL offers transaction immutability without a central operator. The RCL contains a built-in currency exchange and its path-finding algorithm finds competitive exchange rates across order books and currency pairs.

Key Features

  • Distributed
    • Direct account-to-account settlement with no central operator
    • Decentralized global market for competitive FX
  • Secure
    • Transactions are cryptographically signed using ECDSA or Ed25519
    • Multi-signing capabilities
  • Scalable
    • Capacity to process the world’s cross-border payments volume
    • Easy access to liquidity through a competitive FX marketplace

Cross-border payments

Ripple enables banks to settle cross-border payments in real-time, with end-to-end transparency, and at lower costs. Banks can provide liquidity for FX themselves or source it from third parties.

As Ripple adoption grows, so do the number of currencies and counterparties. Liquidity providers need to maintain accounts with each counterparty for each currency – a capital- and time-intensive endeavor that spreads liquidity thin. Further, some transactions, such as exotic currency trades, will require multiple trading parties, who each layer costs to the transaction. Thin liquidity and many intermediary trading parties make competitive pricing challenging.

XRP as a Bridge Currency

Ripple can bridge even exotic currency pairs directly through XRP. Similar to USD in today’s currency market, XRP allows liquidity providers to focus on offering competitive FX rates on fewer pairs and adding depth to order books. Unlike USD, trading through XRP does not require bank accounts, service fees, counterparty risk, or additional operational costs. By using XRP, liquidity providers can specialize in certain currency corridors, reduce operational costs, and ultimately, offer more competitive FX pricing.
