All About Blockchain

Can we have financial privacy AND stop financial crime? Stanford's Darrell Duffie thinks there's a third path and it might be the most important work happening in finance right now.

In this special UBRI Leadership Session, Ripple SVP Eric van Miltenburg sits down with Professor Darrell Duffie of Stanford's Graduate School of Business, U.S. Senate witness, and architect of the course The Future of Money and Payments for a conversation that moves from the theoretical to the genuinely urgent.

Duffie's "compliance by design" framework poses a radical question: what if privacy weren't a switch that governments could flip, but a cryptographic guarantee baked into the payment system itself? It's a question that cuts to the heart of every CBDC debate, every stablecoin regulation, and every fintech pitch deck claiming to serve the unbanked.

In this episode:

• Why the U.S. CBDC is dead and why that might be shortsighted
• How tokenized U.S. Treasuries went from zero to $10B and what clearing banks do next
• Why China's eCNY flopped even with government muscle behind it
• The surprising reason Europe may actually pull off a digital euro
• What Afghanistan's Hesab Pay reveals about stablecoins and financial inclusion
• Why agentic payments; AI making purchases on your behalf may be the real disruption no one's talking about
• And yes: why in 100 years, no one will carry "grubby bits of paper" in their pockets

Whether you're a regulator, a builder, a banker, or just someone who tapped your phone to buy coffee this morning this conversation will change how you think about who controls your money and why it matters.

One documentary. A 4.9-star rating. A kidney community of millions waiting to see it. And nine major studios; Amazon, Apple, HBO Max, Hulu, Disney, Paramount+, Peacock, Showtime, and Stars that all said no.

So Donald stopped asking for permission.

In this episode, Lauren Weymouth sits down with filmmaker Donald Griswold to unpack how he's using Stuff.io, a blockchain platform backed by Mark Cuban and Snoop Dogg, to distribute Abundant directly to the kidney community, bypass the $50M Hollywood P&A machine, and prove that true digital ownership changes everything for independent artists. One in nine Americans is affected by kidney disease. This film could reach every one of them and no traditional streamer could make that happen. Because on a streaming platform, you have a license. On blockchain, you own it. And as Donald says "you can't give it, if you don't own it."

If you're a filmmaker, a creator, or a founder who's been told your project is too niche, this episode is your proof of concept. This isn't just a film launch. It's a manifesto.

In this season opener we dive into the world of Crypto Insurance and the safety net required to bring institutional capital off the sidelines. Host Lauren Weymouth sits down with Sree Sanakkayala, founder of Mintara Labs, to discuss how they are "quantifying the unknown" to bridge the multi-billion dollar protective gap in digital assets.

From a technical residency in Paris to a high-intensity accelerator at Berkeley, Sree’s journey reveals a critical shift in the industry: moving away from complex, crypto-native smart contracts toward regulated insurance products that everyday fintechs and institutions can actually trust.

In this conversation, you will learn:

• The Difficulty with Crypto Audits: Why $2.5 billion was lost in 2025 despite 92% of protocols being audited, and how "copy-paste" coding and human error contribute to massive losses.
• AI-Driven Risk Quantification: How Mintara Labs uses a proprietary AI pricing engine to translate on-chain data into real-world insurance premiums.
• The Future of Stablecoin Safety: Why new US and EU regulations are turning stablecoin reserves into a "built-in" insurance policy, allowing innovators to focus on pure crypto risks.
• Building on XRP Ledger: Discover why the XRPL EVM sidechain was the ideal testing ground for "tradable risk" and high-liquidity financial infrastructure.
• The "Hard Truth" of Startups: Sree shares the pivotal moment of shifting from a "passion project" to a revenue-generating business that serves real customer needs.

The narrative around cryptocurrency is often bogged down by complexity, hype, and fear of scams. In this episode, host Lauren Weymouth cuts through the noise with Ali Tager, Head of Communications for the National Cryptocurrency Association (NCA), to reveal who is really using crypto in America and why.

The NCA is on a mission to bridge the knowledge gap, focusing not on lobbying or existing industry players, but on helping everyday Americans understand and use digital assets with confidence.

In this conversation, you will learn:

• 🧠 The Truth About Crypto Users: Learn surprising stats that debunk the "crypto bro" myth, including why more holders are over 55 than under 25.
• 🛡️ Promoting Safe Adoption: Ali shares the NCA's advice on how to spot scams, the importance of "Do Your Own Research (DYOR)," and the role of strong consumer protections.
• 🏘️ Real-World Utility: Discover how crypto is being used today—from single mothers gaining financial independence to cattle ranchers tracking goods on the blockchain.
• ⚖️ The Role of Regulation: Understand how the NCA works to educate policymakers and why clear "rules of the road" are essential for innovators and consumers alike.

Tune in to hear how the NCA is spearheading a movement toward mainstream adoption by ensuring that when it comes to digital assets, even the "crypto-curious" and "crypto-clueless" have a resource they can trust.

What are the parallels between the early internet boom and today's blockchain revolution? How will the tokenization of every asset—from money and commodities to real estate and private equity—fundamentally reshape global capital markets?

In this episode, host Lauren Weymouth sits down with Mathew Le Merle, a titan of tech investment and the Co-Founder and CEO of Fifth Era and Blockchain Coinvestors. With a portfolio of over 1,500 startups, including more than 80 unicorns like Ripple, Kraken, and OpenSea, Mathew offers a masterclass on the past, present, and future of digital assets.

Recorded live from the Apex conference in Singapore, this special episode of All About Blockchain features a deep dive into the fusion of artificial intelligence and blockchain technology. Host Lauren Weymouth, head of Ripple's University Blockchain Research Initiative (UBRI), sits down with Professor Yang Lui of Nanyang Technological University to discuss a groundbreaking collaboration: building a programmable multi-agent AI ecosystem directly on the XRP Ledger.

Listen in as Dr. Lui shares his journey from traditional cybersecurity to the cutting edge of "agentic AI," where intelligent agents can audit smart contracts, identify zero-day vulnerabilities, and even simulate the thinking of a hacker. They explore the critical difference between AI security and AI safety, sharing fascinating and slightly scary stories of AI agents that learn to "cheat" or act on their own accord. Discover how this new AI layer moves from a white paper to live middleware in under a year, what it means for the XRPL community, and what the future holds as we work to digitize human capabilities like memory, abstraction, and even creativity into the machines that will power the next generation of Web3.
