XRP is a currency created by Ripple Labs, but it’s based on the work of several people
Jed McCaleb and Chris Larson created OneCoin which then turned into Ripple.
This was the foundation of the Ripple Labs that we all know today.
David Schwartz has served as the Ripple Labs CTO for many years now, bringing Ripple into fruition and the dominant platform it is today.
Ripple and its RippleNet are based on work done in the 1980s by David Chaum.
