Ripple uses the distributed ledger technology, blockchain, just like Bitcoin or Ethereum. Ripple's concept enables real-time financial transactions.
Nowadays, international money transfer takes a few days (3-5 days) and the costs are huge. There is literally no other way to send international same-day money other than getting on a plane with a briefcase full of money. Ripple aims to overcome this problem by making it possible to send money across borders within seconds.
XRP (Ripple's own cryptocurrency) "delivers" money anywhere in the world within four seconds, at a cost of a few pennies, that is, it is particularly cost-effective, thanks to the elimination of intermediary banks. In contrast to other coins, the throughput of the system is much more favorable - a hundred times that of the Ethereum system - i.e. it can handle 1500 transactions per second. While Bitcoin can only handle 3-5 transactions per second.
The size of the market is always as big as the demand, the technology is built (Ripple has been working on it since 2012, when the company was founded), their team is world-class and they partner with nearly 100 banks around the world.
The first bank that started using the Ripple Payment Protocol was none other than the German Fidor Bank. Among the banks also known in Hungary, Unicredit joined it.
It is no surprise that many believe that XRP will become the leading cryptocurrency in the future.
