    Episode 180: dYdX’s Antonio Juliano on using STARKs for scalability

    Episode 180: dYdX’s Antonio Juliano on using STARKs for scalability

    This week, Anna and James chat with Antonio Juliano, founder of dYdX, a derivatives exchange on Ethereum that recently transitioned to a StarkEx-powered L2 infrastructure.


    Antonio brings a product-centric perspective to using scalability tech. He explains the choice of going for StarkWare’s products and how it compares to other layer ones or rollups. The conversation delves into questions like dYdX’s position in the decentralization spectrum, how that is going to change in the future, and what the L2 solution enables on the product side.

    Episode 179: Diving into Arbitrum’s Optimistic Rollup

    Episode 179: Diving into Arbitrum’s Optimistic Rollup

    This week, Anna and James host Ed Felten and Steven Goldfeder, co-founders of Arbitrum, an Optimistic Rollup project born before the term "Optimistic Rollup" was even coined.


    Ed and Steven tell Arbitrum’s story, from its beginnings as a chain-agnostic university project in 2014 to become an Ethereum-based Optimistic L2 Rollup solution based on fraud proofs. They cover Arbitrum’s interactive fraud proofs, how they differ from other solutions like Optimism, and how Arbitrum and the Optimistic Rollup helps Ethereum scale.


    Here are some links for this episode:

    Thanks to this episode’s sponsor, Aave


    Aave is an open source, decentralised non-custodial liquidity protocol on Ethereum.


    With Aave, users can participate as depositors meaning they provide liquidity to earn a passive income. or they can also act as borrowers to borrow in an overcollateralized way or undercollateralized way (think: one-block liquidity Flash Loan).


    Aave recently deployed a new market on Polygon’s sidechain to let users pay much lower gas fees. Assets can be transferred from Ethereum with the Polygon Bridge and put to use on Aave’s Polygon markets.

    Episode 178: Exploring SNARKs for Sidechains with Alberto from Horizen

    Episode 178: Exploring SNARKs for Sidechains with Alberto from Horizen

    This week, Anna chats with Alberto Garoffolo from Horizen Labs for their upcoming Zendoo protocol and Latus sidechain proposal.


    The episode centers around the world of sidechains for UTXO-based blockchains such as Horizen or Zcash. The Horizen team has developed Latus and Zendoo, a SNARK-powered mechanism for designing trustless sidechains. Alberto explains how Horizen’s Zendoo system works under the hood to connect a mainchain with a set of sidechains built for specific purposes, while Latus’s design diminishes reliance on bridge validators.

    Episode 177: Unwrapping Optimism with Ben and Mark

    Episode 177: Unwrapping Optimism with Ben and Mark

    This week, Anna and James chat with Ben Jones and Mark Tyneway from Optimism, the builders of Optimistic Ethereum.


    The interview continues the series of L2-focused episodes we have been airing on the Zero Knowledge Podcast and comes just as Optimism gears up for launch. Anna, James, Ben and Mark discuss the inner workings of their Optimistic Rollup, diving deep into concepts like data availability, the fraud proof, the role of the sequencer and the rollup’s complex relationship with layer-one. Ben and Mark then lay out their vision for rollup-centric Ethereum and how rollup interoperability is the next major focus area for the ecosystem.

    Episode 176: Zk-zk-rollup & zk.money with Zac and Joe from Aztec

    Episode 176: Zk-zk-rollup & zk.money with Zac and Joe from Aztec

    In this week’s episode, Anna chats with Zac Williamson and Joe Andrews, respectively CTO and Head of Product at Aztec.


    The episode is centered on Aztec’s latest release, zk.money, the “zk-zk-rollup” that targets privacy and scalability at the same time. zk.money allows users to shield their Ethereum-based assets while achieving a higher transaction count, a result that took months of research and development of the TurboPLONK. Zac and Joe explain how it works down to the nitty-gritty of elliptic curve arithmetic, logic gates, hashes and circuits.


    The conversation then shifts to topics like WebAssembly (and its limitations), Ethereum, UltraPLONK, Noir & more.

    Episode 175: zkEVM & zkPorter with Matter Labs

    In today’s episode, Anna chats with Alex Gluchowski, CEO at Matter Labs and co-creator of zkSync, to catch up on Matter Labs’s latest developments in extending Ethereum’s capabilities with zk proofs.


    Alex explains the recent progress in porting Solidity to a zkRollup and how that interacts with the Zinc language and zk proof circuits. They then move on to discussing Ethereum scalability with a deep dive on rollup architecture and the upcoming zkPorter, a solution for sharded zkRollups that’s being developed by Matter Labs.
