Ripple and had a high dependency of Bitcoin,

Ripple is a real time gross settlement system, by which you can exchange currency and make remittance. It was firstly developed by Ryan Fugger in 2004. He is inspired by a local exchange trading system and then he decided to create a financial system which is decentralized and could efficiently allow individuals and communities to transfer their money. After that, blockchain technology appeared and then Ripple is developed based on blochchain and had a high dependency of Bitcoin, which is considered inefficiently and costly now. In May 2011, Arthur Britto and David Schwartz decided to use a new consensus mechanism. Transactions were no more verified by miners during the mining process, instead network members verify the transaction during each rounds. This improvement had made a significant advancement. It remarkably reduced the time which a single user should wait until his transaction is confirmed and almost cost no charges. In September 2012, they founded OpenCoin Inc. which is called Ripple Labs now and created the native cryptocurrency for Ripple which is called XRP. Nowadays Ripple uses its own blockchain to record ledger and use XRP to maintain the security of its protocol. XRP has another important role, it acts as the bridge currency of Ripple and supports for any type of currency to exchange. XRP is not responsible for the incentive of participants. The incentive scheme of Ripple can be explained as following: Suppose there are two big international companies A and B, they are located in different lands and use different currencies. They cooperate with each other through a trusted third party (an international escorw). However, they both are worried about this trusted third party, who may collude with A or B, so the transaction records between A and B are no more reliable. Under this circumstance, Ripple can help them to maintain a public ledger so that both A and B can make an agreement without trusted third party. Then the payment network will be more reliable and stable. Another benefit is the transfer charges is relative low than using a trusted third party.
