The Ripple payment protocol (also called the Ripple Transaction Protocol (RTXP for short)) is not a typical blockchain solution but works very similarly. Why does Ripple itself arouse such interest and a growing desire to buy from investors? Probably because it is many times faster (transaction processing takes a few seconds) and cheaper than other cryptocurrencies. Secondly, because it is already used by many known and respected financial institutions (Santander, UniCredit or the National Bank of Abu Dhabi). In addition, banks in Japan also plan to implement it. If You don’t know the fundaments for example what is cryptocurrency just read this article.
RippleNet is currently used by e.g. American Express to transfer transactions without using cards. In a sense, this is competition for the current SWIFT system. In addition, Ripple authorities have ambitious plans to expand partnerships and cooperating entities (mainly in the banking and financial industry) e.g. with MUFG (Japan), BBVA (Spain), SEB (Sweden), Akbank (India), YES Bank (India), Axis Bank (India). Ripple has very good opinions among these institutions.
