a16z crypto show

a16z

The a16z crypto show explores how decentralized networks are reshaping money, ownership, and the architecture of the internet. We go beyond the hype to look at what’s actually working, what isn’t, and what comes next as crypto continues to go mainstream and blockchains become core infrastructure. Each episode features conversations with founders, engineers, economists, policymakers, and researchers building at the frontier of finance, payments, AI, and distributed systems. We cover stablecoins and global payments, the tokenization of "real-world" assets, decentralized physical infrastructure, network design and governance, and the practical tradeoffs behind decentralization — along with lessons from past technology shifts. Produced and hosted by the a16z crypto team, the show combines reporting, analysis, and first-principles thinking to explain how crypto intersects with the economy and society — and why it matters now.

    Leslie Lamport on the Science of Distributed Systems

    Before blockchains could reach consensus, Leslie Lamport had to define what agreement even meant when computers fail, lie, or disappear.  In this episode of First Principles: The Scientific Roots of Blockchain Technology, Turing Award-winning computer scientist Leslie Lamport joins Tim Roughgarden Head of Research at a16z crypto and Professor of Computer Science at Columbia University, and a16z crypto Research Partner Ittai Abraham to trace the ideas that helped define modern distributed computing.  Lamport’s work formalized some of the field’s deepest questions: how to reason about concurrent systems, how distributed systems can agree despite failures, and how to prove that protocols do what they are supposed to do. His work on logical clocks, state machine replication, the Byzantine Generals problem, and Paxos has shaped everything from cloud infrastructure to the consensus protocols underlying modern blockchains.  The conversation begins with Lamport’s early work on concurrency and the origins of the Byzantine Generals Problem, and then turns to fault tolerance: what happens when machines crash, behave unpredictably, or even act maliciously? We also cover the feedback loop between theory and practice, the long arc of fundamental research, and how blockchains are inheriting and extending decades of distributed systems work.  Highlights  00:00 – Intro: The problem every blockchain is built to solve  02:52 – Why concurrent systems are surprisingly tricky  04:40 – The origins of the bakery algorithm  07:37 – What does it mean for a protocol to be “correct”?  12:03 – The origins of the Byzantine Generals problem — and what happens when some computers fail  17:49 – How Paxos emerged from an attempted impossibility proof  23:47 – Why theory and practice need each other  33:48 – Government funding, DARPA, and the long arc of foundational research  About First Principles  First Principles is a special limited series from a16z crypto about the scientific roots of modern computing — especially blockchains — told through rare conversations with the pioneers who helped shape the foundational ideas behind distributed systems, consensus protocols, economics, mechanism design, cryptography, zero knowledge, and more.  People often tell the story of the Bitcoin whitepaper as if it appeared out of nowhere. But the ideas behind Bitcoin — and blockchains more broadly — come from decades of computer science, economics, mathematics, and cryptography. First Principles is a guide to that lineage, as told by the people who helped build it.  Hear more from:  Tim Roughgarden: https://twitter.com/Tim_Roughgarden  Ittai Abraham: https://twitter.com/ittaia  Follow a16z crypto:  X: https://twitter.com/a16zcrypto  LinkedIn: https://www.linkedin.com/showcase/a16zcrypto/posts/  YouTube: https://www.youtube.com/@a16zcrypto  Substack: https://a16zcrypto.substack.com/subscribe/  ***  As always, none of the following should be taken as investment, business, legal, or tax advice.

    Before Blockchains, There Was State Machine Replication (ft. Barbara Liskov and Tim Roughgarden)

    Every blockchain today leans on replication ideas worked out in the 1980s, by a Turing Award winner who wasn’t thinking about how it might apply to money at all.  In this episode of First Principles, a16z crypto Head of Research and Columbia professor Tim Roughgarden speaks with Barbara Liskov, MIT professor, Turing Award winner, and one of the most influential computer scientists in programming languages, data abstraction, fault tolerance, and distributed computing. a16z crypto research partner Ittai Abraham joins the conversation.  The discussion traces Liskov’s path from programming languages and modularity to distributed systems research; from CLU and Argus to viewstamped replication; and from benign failures to Practical Byzantine Fault Tolerance, or PBFT — a protocol family whose ideas now shape many modern blockchain systems. Liskov explains why modularity matters, how systems researchers thought about replication in the 1980s, why view changes were such a key idea, and how PBFT extended earlier work to handle malicious behavior on the internet.  The conversation also explores the bridge between theory and practice, the importance of proofs and specifications, and why the next generation of systems research may be reshaped by AI. First Principles is a special, limited series from a16z crypto about the scientific roots of modern computing — especially blockchains — told through rare conversations with the pioneers who helped shape the foundational ideas behind distributed systems, consensus protocols, economics, mechanism design, cryptography, zero-knowledge, and more. People often tell the story of the Bitcoin whitepaper as if it appeared out of nowhere. But the ideas behind Bitcoin — and behind blockchains more broadly — come from decades of computer science, economics, mathematics, and cryptography.  First Principles is a guide to that lineage, as told by the people who helped build it.  Highlights:  00:00 Intro: How do systems stay reliable when parts fail?  01:18 Barbara Liskov’s path from programming languages to distributed systems  05:45 Why modularity is “everything”  07:22 The replication problem: keeping data available across many machines 09:58 Viewstamped replication and the “ledger” before blockchains  16:32 Why good research starts with what you don’t understand  18:10 Leslie Lamport, Paxos, and the inevitability of ideas in the right time, in the right place  21:48 Practical Byzantine Fault Tolerance: what changes when replicas can lie  19:35 How PBFT bridged theory and practical systems  22:38 Why you should never trust an individual replica  28:39 Why blockchains are state machine replication in the wild  31:27 AI, verification, and the future of computer science  Follow:  Tim Roughgarden: https://twitter.com/Tim_Roughgarden  Ittai Abraham: https://twitter.com/ittaia  Follow a16z crypto: X: https://twitter.com/a16zcrypto  LinkedIn: https://www.linkedin.com/showcase/a16zcrypto/posts/  YouTube: https://www.youtube.com/@a16zcrypto  Substack: https://a16zcrypto.substack.com/subscribe/  *** As always, none of the following should be taken as investment, business, legal, or tax advice.

    How Bitcoin Rewired a Classic Computer Science Problem (ft. Tim Roughgarden and Ittai Abraham)

    Bitcoin often gets credited with inventing trustless consensus. It didn’t.  The problem was named decades earlier — in the world of distributed computing — and researchers spent years studying how machines could reach agreement even when some participants were faulty, adversarial, or corrupt. What Bitcoin did was something different: It solved a classic Byzantine agreement problem in a radically new, permissionless setting. And it took the research world years to fully recognize what Satoshi had done. In this episode of First Principles, a16z crypto Head of Research and Columbia professor Tim Roughgarden is joined by a16z crypto research partner Ittai Abraham — one of the world’s leading researchers in Byzantine agreement and consensus protocols, a founding member of VMware’s blockchain project, and founder of the technical blog Decentralized Thoughts — to unpack the scientific roots of blockchain consensus.  Together, Tim and Ittai trace the line from classic distributed systems research to Bitcoin, proof-of-stake, Tendermint, Casper, DAG-based protocols, Solana’s Alpenglow, and the modern race for higher throughput and lower latency. Along the way, they explain why concepts like Byzantine fault tolerance, state machine replication, safety, liveness, and partial synchrony are not just academic abstractions — they are the language and design principles behind today’s blockchain protocols.  This conversation kicks off First Principles: The Scientific Roots of Blockchain Technology — a special, limited series from a16z crypto on the scientific ideas behind modern computing — especially blockchains — told through conversations with the pioneers who helped create them, including Barbara Liskov, Leslie Lamport, and more. Hosted by Tim Roughgarden, the series explores the foundational concepts behind distributed systems and consensus protocols; economics, mechanism and market design; and cryptography, from digital signatures to zero knowledge. People often tell the story of the Bitcoin whitepaper as if it appeared out of nowhere.  But the ideas behind Bitcoin — and behind blockchains more broadly — come from decades of computer science, economics, mathematics, and cryptography. First Principles is a guide to that lineage, told by the people who helped build it.  Highlights  00:00 Introduction to First Principles: The Scientific Roots of Blockchain Technology  00:56 Why consensus matters for blockchains  02:30 Byzantine agreement: The old computer science problem Bitcoin made practical  04:34 Blockchains as a shared system of record: State machine replication and blockchain state  06:41 How two research worlds — distributed computing and crypto — began to converge  07:49 Proof of work vs. proof of stake  09:27 Why Ethereum’s move to proof-of-stake took years  11:08 When crypto rediscovered decades of distributed systems research  11:50 Why BFT became practical 12:49 Throughput, latency, and modern consensus design  14:05 DAG-based protocols and faster blockchains  15:25 Peace time vs. war time: why modern blockchains need two modes  16:47 Theory, practice, and the future of blockchain research    Follow:  Tim Roughgarden: https://twitter.com/Tim_Roughgarden  Ittai Abraham: https://twitter.com/ittaia  Follow a16z crypto:  X: https://twitter.com/a16zcrypto  LinkedIn: https://www.linkedin.com/showcase/a16zcrypto/posts/  YouTube: https://www.youtube.com/@a16zcrypto  Substack: https://a16zcrypto.substack.com/subscribe/  **  As always, none of the following should be taken as investment, business, legal, or tax advice.

    How Stablecoins Are Reconfiguring the Financial System | ft. Eddy Lazzarin and Sonal Chokshi

    Crypto has been walled off from the real economy for years — that's changing.  Sonal Chokshi and Robert Hackett sit down with Eddy Lazzarin, a16z crypto's newest General Partner, to break down why crypto is entering a completely different phase and what gets built once the rules finally catch up to the technology.  The discussion spans:  - what the CLARITY Act actually does and why it changes the design space for crypto founders  - the difference between a network token and a security, and why it needs to be written into law  - why stablecoins are crypto's first real killer app and how the rest of the economy is reconfiguring around them  - how tokens let builders decouple pricing from growth in a way stocks never could  - why 97.8% of the value created in capitalism leaks out, and what that means for anyone trying to capture any of it  Highlights:  00:00 Intro  01:25 What it means to be a GP  02:00 Consensus vs. non-consensus bets  04:27 Network tokens and the CLARITY Act  09:35 Revenue, value capture, and network-token business models  21:18 Stablecoins as crypto’s first killer app  28:52 Engineer-philosopher mindset 39:04 Intellectual influences  52:40 Eddy’s path to crypto 1:03:15 The exuberant adoption phase of AI  1:14:38 Being "pro–AI psychosis"  Follow: Eddy Lazzarin: https://twitter.com/eddylazzarin  Sonal Chokshi: https://twitter.com/smc90  Robert Hackett: https://twitter.com/rhackett  Follow a16z crypto:  X: https://twitter.com/a16zcrypto  LinkedIn: https://www.linkedin.com/showcase/a16zcrypto/posts/  YouTube: https://www.youtube.com/@a16zcrypto  Subscribe for more industry reports, trend updates, news analysis, builder guides, and other resources: https://a16zcrypto.substack.com/subscribe/  As always, none of the following should be taken as investment, business, legal, or tax advice.

    The Real Reason Behind Most DeFi Hacks

    Following a string of major DeFi exploits, we unpack what’s driving the recent rise in hacks across crypto. a16z crypto GP Eddy Lazzarin and security engineer Matt Gleason join host Robert Hackett to take a closer look. Their argument: AI is not introducing entirely new vulnerabilities. It is making existing weaknesses easier to identify and exploit. The question is whether defenders can evolve as quickly as attackers. They also cover: - why “AI-powered hacking” is difficult to measure - how geopolitical tensions may be influencing cyber activity - why defenders should be aggressively stress-testing their own systems - how AI could eventually outperform humans at resisting social engineering - what users can do today to protect themselves online   Timestamps: 00:00 - Intro 00:57 - The surge, explained 01:37 - Did attackers use AI 04:19 - How AI can help defend against attacks 09:16 - The doomsday marketing debate 17:17 - DeFi transparency: opportunities and challenges 21:00 - Social engineering and how to stay safe   Follow along here: Eddy Lazzarin: https://twitter.com/eddylazzarin Robert Hackett: https://twitter.com/rhackett Matt Gleason: https://twitter.com/mg_486662 Follow a16z crypto: X: https://twitter.com/a16zcrypto LinkedIn: https://www.linkedin.com/showcase/a16zcrypto/posts/ YouTube: https://www.youtube.com/@a16zcrypto Subscribe for more industry reports, trend updates, news analysis, builder guides, and other resources: https://a16zcrypto.substack.com/subscribe/   As always, none of the following should be taken as investment, business, legal, or tax advice.

    Why AI is so centralized: How it's built, who controls it, and what comes next

    A few big companies control most of the infrastructure behind AI. Most people experience AI through a wide range of different apps that actually depend on a deeply centralized stack of data and compute. In this conversation, Ben Fielding and Harry Grieve — cofounders of decentralized machine learning protocol Gensyn — explain why this matters, and what it would take to rebuild AI as open infrastructure instead. From unused global compute to the philosophical implications of machine intelligence, they argue that the next evolution of AI must be owned, coordinated, and verified in a fundamentally different way. Highlights  00:00 – Intro  00:29 – The biggest misconception about AI infrastructure  01:20 – Why centralization in AI is a deeper problem than people realize  04:19 – Why AI needs crypto  05:51 – How AI models are trained  08:15 – The rise of autonomous AI agents with onchain identities  10:37 – Lightning round Ben Fielding on X: https://x.com/benfielding  Harry Grieve on X: https://x.com/harrygrieve  Gensyn on X: https://x.com/gensynai  Follow a16z crypto on X: https://x.com/a16zcrypto  Subscribe for more news and updates: a16zcrypto.substack.com   Hosted by Simplecast, an AdsWizz company.
