Leave a review: https://ratethispodcast.com/endgameIt feels like crypto adoption is moving at lightning speed, but is anyone still "in it for the tech"?Eddy Lazzarin, CTO of a16z crypto, joins Amanda Cassatt on Endgame to explore the growing influence of capital markets, and government and regulatory access, in the current landscape, as well as the specific breakthroughs he anticipates in AI and privacy that would make technology once again the driver of progress.Touching on Tornado Cash, they discuss whether privacy technology has a future in an environment where governments are active players in the industry, the impact of the coming massive wave of asset tokenization, and how Eddy expects AI and crypto will actually converge and find product-market fit.From his vantage point at the intersection of new technology and venture investing, Eddy reflects on what real innovation looks like when the narrative is shaped as much by capital as it is by code.This conversation offers a window into how one of crypto’s most influential firms evaluates technology, risk, and opportunity.➡️Talking Points: 00:00 Understanding the Role of CTO at A16Z02:56 A16Z's Evolving Perspective on Venture Capital05:56 The Impact of Regulation on Technology Innovation08:46 Navigating the Intersection of Traditional Finance and Crypto11:46 The Future of Corporate Integration with Blockchain14:43 The Coexistence of Legacy Systems and New Technologies17:43 The Role of AI in Bridging Old and New Systems29:27 Trusting AI: Expanding Boundaries32:31 The Privacy Paradigm: Current Challenges and Future Solutions42:49 Navigating the Future: Privacy, Compliance, and User Experience55:31 Envisioning the Future: A Non-Custodial Financial Ecosystem➡️Show Links: Follow Eddy: https://x.com/eddylazzarinSubscribe to Endgame: https://www.youtube.com/@endgamepodcast Amanda on X: https://x.com/amandacassatt Serotonin on X: https://x.com/serotonin Endgame on Spotify: https://open.spotify.com/show/6iSvbKOJWoEPiAoGmiulkd Endgame on Apple Podcasts: https://podcasts.apple.com/us/podcast/endgame-with-amanda-cassatt/id1801809440 Substack: https://substack.com/@UCInZsV3L1nDGoFjxoNUnPQQ

The Plan for Ethereum to Flip Bitcoin with Etherealize's Grant Hummer
Ethereum has always been the foundation for the next financial system.Amanda Cassatt sits down with Grant Hummer, co-founder of Etherealize, to explore why Ethereum continues to be misunderstood, especially by institutions, and what it will take to change that.They go deep on Ethereum’s cultural and economic DNA, from early narrative missteps to what makes ETH uniquely positioned to dominate tokenization and programmable finance. Grant explains why rollups matter, how proof-of-stake has changed the game, and what Ethereum’s endgame could look like if it wins.Then they turn to Bitcoin. Grant lays out the case for why BTC, despite its mythology, faces real threats from its security model to the looming problem of quantum resistance. As Ethereum continues evolving while Bitcoin stands still, what happens next?This episode makes one thing clear: Ethereum isn’t playing catch-up, it’s playing for keeps.TIMECODES:00:00 The Genesis of Etherealize02:53 Bridging the Gap: Educating Wall Street on Ethereum05:53 Understanding Ethereum's Value Metrics09:11 The Role of Rollups in Ethereum's Ecosystem11:56 The Bull Case for Ethereum: Digital Oil vs. Digital Gold15:09 Ethereum's Future: Tokenization and Market Dynamics18:07 The Battle for Developer Hearts and Minds21:04 Navigating Regulatory Landscapes23:59 The Shift to Proof of Stake: A New Era for Ethereum27:00 Bitcoin vs. Ethereum: The Future of Digital Assets29:59 The Road Ahead for Etherealize and EthereumRESOURCES:Follow Grant: http://x.com/gphummer?lang=enSubscribe to Endgame: https://www.youtube.com/@endgamepodcast Amanda on X: https://x.com/amandacassatt Serotonin on X: https://x.com/serotonin Endgame on Spotify: https://open.spotify.com/show/6iSvbKOJWoEPiAoGmiulkd Endgame on Apple Podcasts: https://podcasts.apple.com/us/podcast/endgame-with-amanda-cassatt/id1801809440 Substack: https://substack.com/@UCInZsV3L1nDGoFjxoNUnPQQ

What If Death Was Optional? Bryan Johnson on Immortality, AI & the End of Meaning
What if the real threat to humanity isn’t death, but the belief that life needs to mean something?In this episode of Endgame, Amanda Cassatt and Bryan Johnson explore the architecture of a world where death is optional and meaning might be too. Rejecting first-principles thinking, the problem-solving method rooted in historical patterns and known truths, Bryan proposes zeroth-principles thinking: a framework that imagines human existence beyond inherited assumptions. In this future, meaning may vanish along with our drive for ambition, legacy, and identity.They discuss why accomplishment might be nothing more than preparation for death, how attachment to power, wealth, and status could undermine our survival, and why it’s easier to imagine the end of the world than the end of capitalism. Bryan also explores a world beyond game theory, where humanity disables evolutionary instincts like competition and status-seeking, treating them as flaws in our biological code.This is a philosophical autopsy of mortality, meaning, and the psychological machinery we’ve built around being human.TIMESTAMPS: 02:56 Debating Life and Death: The Immortality Argument06:06 The Case Against Immortality: Societal Implications08:50 Wealth, Power, and the Future: A Generational Perspective11:51 The Role of Legislation in a Changing Society14:34 The Nature of Meaning: Life, Death, and Legacy17:35 The Evolution of Human Behavior: Risk and Sacrifice20:46 Post-Meaning: Redefining Existence in a New Era23:46 The Future of Innovation: Aging and Stagnation26:27 The Role of AI: Navigating Uncertainty and Change29:26 The Dilemma of Existence: Freedom vs. Attachment32:35 The Final Thoughts: Embracing Uncertainty and ChangeRESOURCES:Subscribe to Endgame: https://www.youtube.com/@endgamepodcast Amanda on X: https://x.com/amandacassatt Serotonin on X: https://x.com/serotonin Endgame on Spotify: https://open.spotify.com/show/6iSvbKOJWoEPiAoGmiulkd Endgame on Apple Podcasts: https://podcasts.apple.com/us/podcast/endgame-with-amanda-cassatt/id1801809440 Substack: https://substack.com/@UCInZsV3L1nDGoFjxoNUnPQQ

Circle Co-Founder on Why Stablecoins Are Winning the Trust War
Can a digitally native dollar outcompete the systems that built global finance?Sean Neville, former Co-CEO and President of Circle, unpacks why stablecoins are not just a side note in crypto, they’re the financial infrastructure quietly reshaping global payments, remittances, and even central bank strategy.Together, Sean and Amanda explore how stablecoins are reshaping global finance, from reducing friction in traditional payment systems to creating programmable money with transparency and trust at the core. They dissect the promise of decentralization, the role of regulatory frameworks like the Genius Act, and how Circle’s long-term compliance strategy sets it apart from competitors like Tether. But the conversation doesn’t stop at crypto. Amanda and Sean dive deep into how AI-native institutions are already emerging, why AI agents may soon become primary economic actors, and what the financial world could look like when reliability matters more than cost. Today, Sean is Co-Founder and CEO of Catena Labs.TIMESTAMPS: 00:00 Understanding Stablecoins08:04 Infrastructure and Governance in Stablecoins13:24 The Evolution of Payment Systems16:33 Regulatory Clarity and the Genius Act21:20 Market Dynamics: Circle vs. Tether25:42 The Rise of Stablecoins29:39 AI Native Financial Institutions34:34 The Future of AI in Finance45:59 Navigating the AI Spectrum: Doomers to BloomersRESOURCESSean on X: https://x.com/psnevilleSubscribe to Endgame: https://www.youtube.com/@endgamepodcast Amanda on X: https://x.com/amandacassatt Serotonin on X: https://x.com/serotonin Endgame on Spotify: https://open.spotify.com/show/6iSvbKOJWoEPiAoGmiulkd Endgame on Apple Podcasts: https://podcasts.apple.com/us/podcast/endgame-with-amanda-cassatt/id1801809440 Substack: https://substack.com/@UCInZsV3L1nDGoFjxoNUnPQQ

UBI Is Inevitable: Gnosis Founder Martin Köppelmann Says Crypto, Not Governments, Are the Answer
Do you think UBI is inevitable in an AI-driven world?Martin Köppelmann, co-founder of Gnosis, Gnosis Safe, and Circles, believes Universal Basic Income isn’t just possible, it’s inevitable. In a world where AI disrupts the job market, he says we won’t be able to rely on states or billionaires to deliver it.In this episode, Martin and Amanda unpack what “basic” income should really mean. He argues UBI should be simple, universal, and free from government control, biometric scans, or eligibility checks and believes crypto offers a way for communities to create and distribute money themselves without needing permission from centralized powers.Known for building trusted infrastructure in crypto, Martin has spent the last decade quietly obsessed with another question: how do we fund human dignity from the ground up? This is a conversation about post-AI economics, the limits of state welfare, and why issuing your own money might be the most radical and necessary act of all.TIMESTAMPS: 00:00 The Future of Universal Basic Income (UBI)05:33 AI's Impact on Job Markets and UBI09:06 The Mechanics of UBI Implementation12:02 Defining Basic Needs for UBI15:33 Funding UBI: Who Pays?18:49 Preventing Inflation and Maintaining Purchasing Power20:20 Managing Scope Creep in UBI Programs23:13 Dependence on UBI and Societal Resilience25:44 Crypto and UBI: A New Economic Model30:40 Circles: A Community-Based Currency System32:57 The Currency Debate: Martin Tokens vs US Dollar38:00 Circles: A New Approach to Currency42:35 WorldCoin vs Circles: A Comparison of UBI Approaches46:54 Decentralized UBI: Empowering Individuals48:22 Circles 2.0: New Features and Future Prospects54:43 AI Doomsday: The Future of Humanity and AIRESOURCESMartin on X: https://x.com/koeppelmann @koeppelmannSubscribe to Endgame: https://www.youtube.com/@endgamepodcast Amanda on X: https://x.com/amandacassatt Serotonin on X: https://x.com/serotonin Endgame on Spotify: https://open.spotify.com/show/6iSvbKOJWoEPiAoGmiulkd Endgame on Apple Podcasts: https://podcasts.apple.com/us/podcast/endgame-with-amanda-cassatt/id1801809440 Substack: https://substack.com/@UCInZsV3L1nDGoFjxoNUnPQQ

The Quantum Threat to Bitcoin, Ethereum, and DeFi with John Lilic & Stefano Gogioso
Could quantum computers destroy Bitcoin?John Lilic, early Ethereum adopter and crypto investor and Stefano Gogioso, quantum computing expert and Oxford lecturer, unpack one of the biggest threats on crypto’s horizon: Q-Day - the moment quantum computers become powerful enough to break the encryption behind Bitcoin, Ethereum, and the entire blockchain ecosystem.Together with Amanda, they dive deep into what quantum cryptography actually means, why current encryption standards are dangerously outdated, and what crypto needs to do right now to prepare for a post-quantum world. John and Stefano debate how close Q-Day really is, what’s being done (or not) to prevent chaos in the stablecoin and DeFi systems, and why this topic isn’t getting the attention it deserves.TIMESTAMPS00:00 The Threat of Quantum Cryptography05:03 Understanding Quantum Computing and Its Implications10:04 The Race for Quantum Computing Technology14:55 Use Cases and Applications of Quantum Computing19:48 The Preparedness of Blockchain for Quantum Threats28:32 The Quantum Threat to Cryptography31:41 Market Perceptions and Quantum Computing34:55 Valuations in Quantum Computing35:43 Understanding Quantum Progress and Its Implications39:08 The Future of Quantum Cryptography41:38 Innovations in Quantum Cryptography48:12 Preparing for Quantum Risks51:41 Philosophical Implications of Quantum MechanicsRESOURCESJohn & Stefano on X: @LilicJohn & @StefanoGogiosoSubscribe to Endgame: https://www.youtube.com/@endgamepodcast Amanda on X: https://x.com/amandacassatt Serotonin on X: https://x.com/serotonin Endgame on Spotify: https://open.spotify.com/show/6iSvbKOJWoEPiAoGmiulkd Endgame on Apple Podcasts: https://podcasts.apple.com/us/podcast/endgame-with-amanda-cassatt/id1801809440 Substack: https://substack.com/@UCInZsV3L1nDGoFjxoNUnPQQ

The $500M Plan to Start a New Civilization with Praxis' Dryden Brown
What if the future of civilization isn’t in fixing our current systems—but starting entirely new ones? Dryden Brown is the co-founder of Praxis, the ambitious project aiming to build a new city-state from the ground up—one that’s already backed by over $500 million in funding. Dryden shares his vision for a modern Atlantis: a society designed as a refuge from AI disruption and bureaucratic gridlock, born from the cracks COVID revealed in our existing cities. Together, Amanda and Dryden unpack what it actually takes to found a new nation. They dive into acceleration zones, AI’s seismic impact on the future of work, and the provocative question of whether heroism means elevating the elite or defending the powerless. At the heart of it all: the urgent need to build communities rooted in shared values, meaning, and resilience.

Why Washington Matters for Crypto
Crypto went from being laughed out of the room in Washington to becoming one of the most aggressive forces in modern lobbying. Now, it’s not just part of the conversation, it’s reshaping the rules from the inside. Kristin Smith, CEO of the Blockchain Association, reveals the real dynamics between crypto and Capitol Hill. Amanda and Kristin unpack how crypto gained power in DC and what it actually takes to keep it.
