"Ripple is a payment system, currency exchange and remittance network by Ripple Labs. It is built upon a distributed, open source internet protocol, consensus ledger and native currency called ripples (XRP). The Ripple network purports to enable "secure, instant and nearly free global financial transactions of any size with no chargebacks". It supports any fiat currency (dollars, yen, etc.), cryptocurrency (bitcoin, litecoin, etc.), commodity or other unit of value (frequent flier miles, mobile minutes, etc.)."
