Ripple is the currency used on RippleNet, a digital payment platform. RippleNet is recorded on a distributed ledger database called the XRP Ledger. Therefore, Ripple is recorded in their own distributed ledger database, not a payment system made of blockchain . This means that it is a virtual currency that has lost the decentralization, transparency, and security that are the characteristics of blockchain, and has been criticized by the public. They use their own Ripple Protocol Consensus Algorithm. For more info click here https://coin-labs.com/
