An overview of proof-of-stake blockchains -- from quick background on how blockchains work, difference between PoS & PoW, and approaches to improving both; to digging deeper into Sybill attacks and Sybill resistance; and much more on the design (and some debates) of PoS blockchains overall.

"Layer 2” rollups are computer networks that are designed to help scale “layer 1” blockchains such as Ethereum — and they've been bustling with activity recently, especially since Ethereum implemented its scaling-related EIP-4844 ("Dencun") upgrade in March. Jesse Pollak, who is Coinbase's head of protocols and who founded and leads the popular layer 2 rollup Base, joins a16z crypto engineer Noah Citron and host Robert Hackett to discuss bottom-up vs. top-down innovation, models of leadership, software development roadmaps, and building the onchain economy.

Layer 2, Rollups, and Building Onchain (with Base)

Verifiable computing is a method for trustlessly outsourcing computation — and it’s a fast-developing area of technology that could help scale blockchains and, more broadly, decentralize the internet. We explore this world through the lens of zkVMs — or zero-knowledge virtual machines — tools that enable computers to prove that they ran programs correctly, as well as the SNARKs that enable them to work their magic. In this episode, members of the a16z crypto research and engineering teams discuss their year-long close collaboration to develop the simplest, most performant zkVM to date: Jolt.

Chris Lee is cofounder of IYK, a startup that makes digital experiences tangible through NFC chips. Michael Blau is a deal partner at a16z crypto and part-time generative artist. And Robert Hackett is an editor at a16z crypto. They discuss the merging of the digital and physical, new consumer experiences enabled by chipped goods, the challenge of counterfeits and bots, and more.

Let's Get Digi-Physical: From 'Tap' Chips to Taylor Swift

All about how technology has changed art, and how artists change with technology – from the emergence of the browser, the iPhone, and social media; to generative AI art and blockchains to NFTs. We (with guest Simon Denny) also discuss debates that seem to come up in every art x tech shift -- including inventing vs. remixing; between commercialism and art; between mainstream canon and fringe art; whether we’re living in an artistic monoculture now (the answer may surprise you); and much more.

The Art of Technology, The Technology of Art

Brian Armstrong is CEO and cofounder of Coinbase. Chris Dixon is founder and managing partner of a16z crypto. They discuss Coinbase's early days, the fallout from FTX, crypto in politics, company building, product development, and more.
