Ripple is a real-time gross settlement system, currency exchange and remittance network by Ripple. Also called the Ripple Transaction Protocol or Ripple protocol, it is built upon a distributed open source Internet protocol, consensus ledger and native currency called XRP. Released in 2012, Ripple purports to enable "secure, instant and nearly free global financial transactions of any size with no chargebacks." It supports tokens representing fiat currency, cryptocurrency, commodity or any other unit of value such as frequent flier miles or mobile minutes. At its core, Ripple is based around a shared, public database or ledger, which uses a consensus process that allows for payments, exchanges and remittance in a distributed process.
Yeah, but I don't think it will overpower Bitcoin.
I think Bitcoin will be the leader for a while, Ethereum will definitely be a major player as will Ripple, IOTA has partnered with Bill Gates Microsoft and has a newer technology. I also think Steem will give Facebook a run for the money.
