Ripple is a real-time gross settlement system, currency exchange and remittance network created by Ripple Labs Inc., a US-based technology company. Released in 2012, Ripple is built upon a distributed open source protocol, and supports tokens representing fiat currency, cryptocurrency, commodities, or other units of value such as frequent flier miles or mobile minutes. Ripple relies on a common shared ledger, which is a distributed database storing information about all Ripple accounts. The network is "managed by a network of independent validating servers that constantly compare their transaction records." Servers could belong to anyone, including banks or market makers. Ripple validates accounts and balances instantly for payment transmission and delivers payment notification within a few seconds. Payments are irreversible, and there are no chargebacks.
