Welcome to web3 with a16z. Today we’re talking about the ins and outs of blockchain performance.

How does the “speed” of one chain compare to another? What are the tricky ways that people talk about important metrics like throughput and latency? And how do design choices across things like consensus and execution result in performance tradeoffs?

Our guest today is Aptos Labs’ Head of Research Sasha Spiegelman, who is helping build out and develop technologies he originally co-created at Meta. We’re also joined by a16z crypto Head of Research and Columbia University professor Tim Roughgarden, who specializes in the intersection of computer science and economics, which is fitting as we dig into technical details throughout.

5 Charts That Explain Crypto Right Now 28:47

לפני 7 ימים28:47

28:47

with @DarenMatsuoka @rhhackett Today we've got a midyear market update and news episode for you. At the end of last year, our guest — and resident data weatherman — Daren Matsuoka put out a post on " 5 metrics to watch in 2025 ." Most of the metrics that Daren picked measure how crypto's adoption: from mobile wallet usage and onchain transaction fees to volume across stablecoins, decentralized exchanges (or DEXs), and exchange traded-products. Now that we're about midway through 2025, it's a great time for an update. Timestamps: (0:00) Introduction (2:27) Chart 1: Monthly Mobile Wallet Users (6:16) Chart 2: Adjusted Stablecoin Transaction Volume (10:01) Chart 3: ETF Net Flows for Bitcoin and Ethereum (13:30) Chart 4: Decentralized vs Centralized Exchange Volume (15:50) Chart 5: Total Transaction Fees (21:46) Emerging Metrics and Industry Insights (25:07) Recent Industry News and Developments (27:13) Conclusion Relevant news: Circle, issuer of the USDC stablecoin, went public on the New York Stock Exchange exchange on June 5 and there was extremely strong demand for the company's offering. Stripe announced on June 11 that it would be acquiring a crypto company, Privy, which helps companies create crypto wallets — adding to Stripe's earlier acquisition of Bridge, which helps companies work with stablecoins. Shopify partnered with Stripe and Coinbase to enable merchants to accept USDC payments. Coinbase has a new credit card in partnership with American Express, which gives you Bitcoin rewards. The French bank Société Générale announced plans for a dollar-backed stablecoin that will run on Ethereum and Solana with BNY Mellon acting as custodian for the reserves. JPMorgan Chase plans to launch a U.S. dollar “deposit token” called JPMD on Coinbase's Base network. If you enjoyed this episode, stay tuned for our annual big State of Crypto Report , which we'll drop in the fall.

with @MinarikLaw @EMinSF @rhhackett Imagine waking up one day to find your bank account frozen. No warning. No explanation. No recourse. This is not a thought experiment. It’s a real situation. And it’s happened not just to crypto companies and their founders, but to ordinary people who are just trying to live their lives. That includes our guest today, who learned firsthand what it means to be “debanked.” In this episode, we talk about the unseen algorithms that monitor people’s accounts, the ramifications of the Bank Secrecy Act, and how crypto and decentralized finance may offer a much-needed check — and safety net — against the opaque systems of traditional finance. Joining us are: Uniswap Labs’s Chief Legal Officer Katherine Minarik , who shares her personal story of being debanked and what it taught her. a16z crypto Finance and Operations Partner Em Westerhold , who helps founders navigate these issues, and who has tracked dozens of instances of debanking across our own portfolio.

with @aeyakovenko @alive_eth Today’s episode features Solana cofounder Anatoly Yakovenko in conversation with a16z General Partner Ali Yahya, recorded live at our CSX Crypto Startup Accelerator program earlier this year. Anatoly shares the origin story of Solana — from a late-night eureka moment to thousands of investor meetings and several near-death startup experiences. He talks about what it took to get the network off the ground, how his engineering background at Qualcomm shaped its design, and why a need for speed gave Solana its edge. They also get into developer culture, engineering trade-offs, and what differentiates Solana’s approach to building — including its willingness to ship, iterate, and rethink everything: including, most recently, its consensus algorithm .

AI vs. ID: Proof of human in a world of agents, bots, deep fakes, more 2:04:31

לפני 28 ימים2:04:31

2:04:31

with @eddylazzarin @adrian_ludwig @remco @smc90 Hi everyone, welcome to this week’s episode of web3 with a16z podcast, I’m Sonal, and today we’re talking about a hot topic which is also very evergreen because we’re entering a world where AI – including AI agents, bots, deep fakes, and so on -- are changing the internet, very drastically. And so we will need proof of who’s human, or not, online – aka “ proof of human ” (as Tools for Humanity and World app call it). The theme is actually represented on the latest cover of Time magazine , which features the Tools for Humanity orb: a ball-like hardware device that maps your eye’s iris code to an app on your phone to verify you’re human. (It’s actually only the fifth time in the past decade that hardware tech’s been on the cover; the other times are the iphone, Oculus, consumer drones, and SpaceX.) Since the technology -- and network -- story here draws on both existing and new tech to help solve what’s actually a *very* difficult problem -- and in a way where privacy is by default -- we begin with the why it matters, then go into some common questions, and finally how it all works under the hood. Our expert guests are: Eddy Lazzarin, CTO at a16zcrypto; Adrian Ludwig, Chief Architect and CISO at Tools for Humanity; and Remco Bloemen, Head of Protocol at World.

with @cdixon @SamBroner @rhhackett Stablecoins are quietly transforming how money moves — faster, cheaper, and more globally than ever before. In this episode, we take a deep look at why stablecoins have emerged as one of the most promising applications in crypto today — and how they could reshape global payments. I’m joined by Chris Dixon, founder and managing partner of a16z crypto and author of the New York Times -bestselling book Read Write Own , and Sam Broner, a deal partner at a16z crypto who focuses on stablecoins. Together, we unpack the technical and regulatory foundations of stablecoins, explore the cracks in the current payments system, and look ahead to what becomes possible once digital dollars go mainstream. We also dig into the current state of regulation — and why the future of money might end up looking a lot more like email or the web than a bank. Check out the show notes for links and resources that we reference throughout this episode. Also be sure to listen to the episode we dropped just before this one where we analyze all the recent stablecoin news.

Quantum Computing: What, When, Where, How 1:15:13

לפני 7 weeks1:15:13

1:15:13

with @danboneh @succinctJT @smc90 This episode is all about quantum computing -- what it is, how it works, what's hype vs. reality, and how to prepare for it/ what builders should do. Specifically, we cover: What quantum computing is and isn't, and what people are really talking about when they worry about a quantum computer that can break cryptographic systems that are not secure against quantum attacks. When is it happening/ what are the "timelines" for quantum computing becoming a reality -- or rather, when could we have a cryptographically relevant quantum computer -- how many years away are we? and when are the U.S. government's deadlines/ NIST standards for post-quantum cryptography? How will different types of cryptography be affected, or not? What are different approaches and tradeoffs? Where does quantum computing and post-quantum crypto apply to blockchains -- which by and large rely on signatures, not encryption, so may be more quantum-resistant in many ways (and not in others)... As always, we tease apart the signal vs. the noise in recent "science-by-press release" corporate quantum-computing milestone announcements. We also help answer questions on when do builders need to plan their switch to a post-quantum crypto world, what pitfalls to avoid there (hint: bugs! software upgrades!). Finally, we briefly cover different approaches to post-quantum crypto; and also dig deeper on zero-knowledge/ succinct-proof systems and how they relate to post-quantum crypto. Our expert guests, in conversation with Sonal Chokshi, are: Dan Boneh , Stanford University professor and applied cryptography expert and pioneer; also Senior Research Advisor to a16z crypto; Justin Thaler , research partner at a16z, professor at Georgetown, and longtime expert and pioneer in interactive and ZK proof systems.

Your Guide to Tokens: Types, Design, Uses, More 1:41:36

לפני 9 weeks1:41:36

1:41:36

with @eddylazzarin @skominers @milesjennings @rhhackett Today we're diving deep into *the* defining concept in crypto: tokens. We're moving beyond conventional categories — like “governance tokens” or “utility tokens” or even “memecoins” — to present a full taxonomy that details what tokens are, what they aren’t, and what they're capable of becoming. Questions we'll explore include: What is a token? Is it a form of money? A piece of data? Something else? How many types of tokens are there — and who is in control of each? And how should we think about their actual economic, legal, and technical characteristics? We'll also dig into different token designs and their uses; where tokens derive value from; how they jibe with securities laws; and much more. In this conversation, you’ll hear from several experts on the a16z crypto team who have developed a new 7-part framework for classifying tokens , which you can find linked below. Joining us are the coauthors: Chief Technology Officer Eddy Lazzarin, General Counsel and Head of Policy Miles Jennings, and Research Partner Scott Kominers, who is also a Professor at Harvard Business School where he teaches courses on market design and entrepreneurship. Check out the resources below for a flowchart that we’ll also be referencing throughout this episode and that will be helpful as we wend our way through the token idea maze.

with @ilblackdragon @rhhackett Welcome to web3 with a16z . I’m your host, Robert Hackett. In this episode, we're diving deep into one of the most intriguing intersections in tech today: AI and crypto. To help us unpack it, we're joined by Illia Polosukhin — co-founder of the crypto protocol NEAR and co-author of the groundbreaking 2017 "transformers" paper that kicked off the current AI boom. Ilia has been early to some of the biggest recent tech trends, and today he brings us a rare, panoramic view of the tech industry’s cutting edge. Together we explore what the phrase “user-owned AI” really means; why the so-called agentic internet — that is, a world where your AI assistant talks directly to services on your behalf — might replace the very notion of websites and apps as we know them; and much more.

Congestion Pricing? Economics, Theory, Reality 57:31

לפני 13 weeks57:31

with @mostrovs @skominers @rhhackett Welcome to web3 with a16z . I’m your host Robert Hackett, and today we’re talking about congestion pricing — an area of mechanism design that’s aimed at alleviating something everyone hates: traffic. Now you may have heard this term recently since New York adopted its own version of congestion pricing at the beginning of the year. This is the first program of its kind in the U.S. — and it’s got supporters and detractors. We’ll talk about that, and we’re also going to talk about much more. In the first part of today’s episode we’ll trace the history of the economic ideas that got us here. In the middle, we’ll dig deeper into the details of putting congestion pricing into practice, plus technological alternatives. And in the final part, we’ll explore parallels to — and implications for — crypto networks. Our guests are Michael Ostrovsky, a Stanford Economics Professor who specializes in this area and who has done research on congestion pricing in New York. We’re also joined by a16z crypto Research Partner Scott Kominers, who is a Professor of Business Administration at Harvard Business School where he teaches market design and entrepreneurship. Timestamps: (0:00) introduction (1:51) NYC proposal history (3:38) economic theory of congestion pricing (9:15) implementation: challenges and solutions (26:00) technological alternatives and drones (29:49) overnight delivery and other possibilities (35:20) carpooling and how to encourage it (39:34) congestion pricing and crypto (47:59) lessons for blockchains Resources: Michael Ostrovsky's paper on congestion pricing in New York City (from before the launch, foreseeing its issues): https://web.stanford.edu/~ost/papers/nyc.pdf Michael Ostrovsky's thread that went viral on X shortly after the debut of congestion pricing in New York, discussing the post-launch evidence, his team's data collection efforts, and the link between observed data and predictions in the above paper: https://x.com/mostrovs/status/1876798157595476420 Two of Ostrovsky's earlier theoretical papers on the topic: (1) https://web.stanford.edu/~ost/papers/complementarity.pdf , (2) https://web.stanford.edu/~ost/papers/sdc.pdf Economist William Vickrey's influential paper on congestion pricing: Vickrey, W.

Welcome to web3 with a16z . Today we’re talking about a founder’s journey from academia to the tech startup world — and the many lessons he’s learned along the way. We dig into big ideas, like what people mean when they call blockchains "truth machines." We also share practical advice and insights, like how to go about deciding on your life’s work; what you can do to keep increasing — and compounding — your leverage; plus, how a bungled interview question can change your life. Today’s episode features a conversation between Eigen Labs Founder Sreeram Kannan, formerly an associate professor at the University of Washington where he led its Blockchain Lab, and a16z crypto General Partner Ali Yahya. This conversation originally took place in the fall at our CSX crypto startup accelerator in New York.

with @SashaSpiegelman @Tim_Roughgarden @rhhackett Welcome to web3 with a16z. Today we’re talking about the ins and outs of blockchain performance. How does the “speed” of one chain compare to another? What are the tricky ways that people talk about important metrics like throughput and latency? And how do design choices across things like consensus and execution result in performance tradeoffs? Our guest today is Aptos Labs’ Head of Research Sasha Spiegelman, who is helping build out and develop technologies he originally co-created at Meta. We’re also joined by a16z crypto Head of Research and Columbia University professor Tim Roughgarden, who specializes in the intersection of computer science and economics, which is fitting as we dig into technical details throughout. Timestamps: (0:00) introduction (2:48) understanding blockchain metrics (7:59) consensus protocols: PBFT and beyond (14:56) innovations from Meta’s Novi to Aptos (20:51) optimizing blockchain execution (with BlockSTM) (25:23) tech debate: dynamic vs. static parallelism (27:55) open source and the prisoner’s dilemma (29:15) conclusion *** As a reminder, none of the content should be taken as tax, business, legal, or investment advice.
