Welcome to our special end-of-year episodes -- which also look ahead to 2025 --  covering our annual Big Ideas lists, where various a16z crypto team members share what they are personally excited about. (You can see the firmwide list, also including all the trends of the crypto team,  here.)

This episode is part 2 of 2 -- but you don't have to listen to them in any particular order -- covering the intersection of crypto & AI:

• agents that have their own crypto wallets -- and also AI agents in games; DePin/ decentralized physical infrastructure, like energy grids; and more;
• proof of personhood, and why having a unique ID matters in a world of deepfakes, bots, scams and more is needed with proliferating AI;
• decentralized, truly autonomous, chatbots (using TEEs or trusted execution environment).

 Covering each of these -- and coming from the investing, engineering, and other teams -- are:  Carra Wu, Eddy Lazzarin, and Karma (aka Daniel Reynaud); in conversation with hosts Sonal Chokshi and Robert Hackett, who also share some commentary at the top.

These are just a few of the 14 trends we shared; you can check out the full list at a16zcrypto.com/bigideas. 

Also be sure to check out part 1, which covers the trends of stablecoins, app stores, infrastructure, and user experience.

This episode is part 1 of 2 -- but you don't have to listen to them in any particular order -- covering the trends and themes of:

• stablecoins, payments, and where the early adopters will come from;
• app store distribution, curation, and discovery;
• where the next crypto users will come from, turning passive holders into active users;
• how builders improve, and better choose, infrastructure; and
• simplifying user experience.

 Covering each of these -- and coming from the investing, go-to-market, data science, research, and media teams are:  Sam Broner, Maggie Hsu, Daren Matsuoka, Joachim Neu, and Chris Lyons; in conversation with hosts Sonal Chokshi and Robert Hackett.

We've heard a lot about the premise and the promise of prediction markets for a long time, but they finally hit the main stage with the most recent election. So what worked (and didn't) this time? Are they better than pollsters, journalists, domain experts, superforecasters?

So in this conversation, we tease apart the hype from the reality of prediction markets, from the recent election to market foundations... going more deeply into the how, why, and where these markets work. We also discuss the design challenges and opportunities, including implications for builders throughout. And we also cover other information aggregation mechanisms -- from peer prediction to others -- given that prediction markets are part of a broader category of information-elicitation and information-aggregation mechanisms.

Where do (and don't) blockchain and crypto technologies come in -- and what specific features (decentralization, transparency, real-time, open source, etc.) matter most, and in what contexts? Finally, we discuss applications for prediction and decision markets -- things we could do right away to in the near-to distant future -- touching on everything from corporate decisions and scientific replication to trends like AI, DeSci, futarchy/ governance, and more?

Our special expert guests are Alex Tabarrok, professor of economics at George Mason University and Chair in Economics at the Mercatus Center; and Scott Duke Kominers, research partner at a16z crypto, and professor at Harvard Business School  -- both in conversation with Sonal Chokshi.

Today we’re dusting off an ancient practice that has become trendy once again: the old-but-new idea of “sortition,” or selecting representatives by lottery.

Sortition was used in ancient Athenian democracy to elect public officials. It’s also been lately revived by tech companies like Meta and AI startups like OpenAI and Anthropic to tackle some of their thorniest policymaking challenges.

Our guests today are experts on sortition, including Bailey Flanigan, a postdoctoral fellow at Harvard who is joining MIT as an assistant professor next year, and who has helped develop selection algorithms for sortition that are in use today. Also joining is Andrew Hall, Stanford University poli sci professor, advisor to Meta, and consultant to a16z crypto research.

In this episode, we discuss why not to rely exclusively on expert authority, how the process of deliberation changes people’s minds, and how sortition can apply everywhere from the governance of countries to the governance of crypto projects, and more.

Welcome to web3 with a16z. Today we're taking you behind the scenes of our newly released, annual State of Crypto Report — a16z crypto's analysis of the latest data and trends that have defined the industry in 2024.

This year's report features some brand new insights, from estimating the number of real crypto users globally, to understanding how much interest in crypto swing states may have ahead of the U.S. election. We also dig into infrastructure improvements to blockchains and key applications — including stablecoins, AI, and so-called DePIN. Be sure to visit a16zcrypto.com for all this and more including a new “Builder Energy” dashboard, which we’ll discuss on the show.

Joining me to talk about the findings are lead data scientist and report author Daren Matsuoka and CTO Eddy Lazzarin. The first voice you'll hear after mine is Daren's, then Eddy's.

Welcome to web3 with a16z. Today we explore the messy secrets of blockchain bridges. These cross-chain connectors are the go-betweens in today's multichain world, but their short history has been a checkered one, with prominent projects succumbing to major hacks and other hijinks.

So we've brought on one of the builders who knows this world best to help disentangle the messiness. That’s Bryan Pellegrino, cofounder and CEO of LayerZero Labs, maker of a popular blockchain interoperability protocol. In this episode, Bryan delivers a crash course on the evolution of bridges, including the ups and downs of various approaches. You'll also learn about the technology's inner workings, its applications, and how it fits in with ongoing efforts to scale blockchains.

Joining is a16z crypto general partner Ali Yahya, who is also an expert in this area; plus me, your cohost, Robert Hackett. The first voice you'll hear after mine is Bryan's, then Ali's.

In this special 50th episode of the web3 with a16z podcast, we discuss how work in the blockchains/ crypto space has led to advances in several important technologies — which can be (and are being) used by many other industries beyond crypto.

Tim Roughgarden (a16z crypto Head of Research and professor at Columbia University) and Dan Boneh (a16z crypto Senior Research Advisor and professor at Stanford University) discuss these advances in conversation with Sonal Chokshi. 

Topics covered include automated market makers; credible auctions, collusion, and mechanism design not possible before; as well as zero knowledge; trusted execution environments (TEEs) and fully homomorphic encryption (FHE); and much more. We also discuss the recurring theme of how web3 provides a laboratory not only for experiments in governance, but for macroeconomics and more. The two also offer many useful explanations for anyone new to these technologies or seeking to understand why they matter in the big picture. 

It’s an innovation story we’ve seen over and over again, from the space program to other massive invention efforts: Technologies developed for one purpose often lead to benefits for humanity overall.

In this episode, we cover both recent events + evergreen governance questions in political systems: Specifically, we breakdown the recent Compound “governance attack”... as well as the broader topic of DAO governance and voting in general. We also discuss how to avoid, prevent, and respond to such governance attacks -- highlighting key differences between on-chain/ token-based/ digital voting systems vs. physical-world political systems around the world. 

What happens when you have activity from actors that the majority doesn’t necessarily agree with? How do you distinguish between good-faith and bad-faith activity, especially on-chain? And other such tricky questions?? Our experts answering these questions (in conversation with Sonal Chokshi) include: 

- a16z crypto CTO Eddy Lazzarin;
- head of network operations Ross Shuel;
- and a16z crypto research collaborator, and Stanford professor of political science, Andrew Hall.

The episode begins by quickly recapping the exact sequence of a recent Compound governance “attack” event a few weeks ago -- including discussing whether “governance attack” is the right label for it or not; how it’s different from other attacks; and the broader trend of online vs offline governance attacks in general -- before then going into specific solutions. The team also shares some behind-scenes tick tock on what happened, how people figure out motives behind actions on-chain (especially given the "indistinguishability problem"), and much more.
