The Internet of Money: Why Bitcoin Is the Future of Global Value Transfer | David Marcus

“If the internet could move value natively… would you use anything else?” I sit down with David Marcus, a true fintech veteran and the co-founder and CEO of Lightspark. You might know him from his time at PayPal, Meta where he led Messenger, or the ambitious Libra/Diem project. Now, he’s on a mission to build the open internet of money—on Bitcoin. We dive into David’s fascinating journey through startups, global payments, and Silicon Valley, before unpacking the philosophy and architecture behind Lightspark. We explore how Bitcoin is evolving beyond store of value into a global settlement layer, how Spark enables stablecoin issuance and self-custodial wallets on Bitcoin, and why compliance, scalability, and user experience are critical for mass adoption.
