Charles Hoskinson, the founder of Cardano, addresses some common misconceptions about XRP, the native cryptocurrency of the Ripple network. He argues that XRP is not a security, that it is not centralized, and that it is useful for facilitating fast and cheap cross-border payments. Hoskinson also highlights some of the key differences between Cardano and Ripple, including that Cardano is a proof-of-stake blockchain that is focused on developing decentralized applications, while Ripple is a private network that is focused on facilitating payments between financial institutions.
