About This Episode
In this episode of the Leaders in Payments and Fintech podcast, host Mark Beresford sits down with Diederick Langstraat and Thibault Pelé from Worldline, alongside Samee Zafar, CEO of Edgar, Dunn & Company, to explore the emerging world of stablecoins and central bank digital currencies (CBDCs). They discuss how stablecoins differ from volatile cryptocurrencies and traditional payment rails, and examine real-world use cases from cross-border payments to tokenized assets.
The conversation covers blockchain's role in enabling native interoperability between payment systems, the regulatory frameworks shaping adoption like Europe's MiCA, and whether stablecoins offer genuine advantages over existing instant payment networks. They also explore emerging applications in gaming micropayments, social commerce, and agentic commerce.
