A Deep Dive into the Polygon zkEVM with Jordi Baylina
Today's guest is Jordi Baylina, who leads the technical team building the Polygon zkEVM. The polygon zkEVM launches in late march, and this episode will serve as your technical introduction to how the zkEVM works. We got deep into how Jordi & the team pulled this off - we talked through how the prover & sequencer works, stepped through a sample transaction step by step, and got into just how his team was able to pull off opcode parity w Ethereum L1 (and some of the tradeoffs with supporting full EVM compatibility).If you’re interested in deploying atop the zkEVM or just understanding how it works from a technical point of view, I think you’ll enjoy this episode!00:00 Intro3:22 How Jordi got into crypto6:33 What is Polygon’s zkEVM?9:34 Enabling opcode parity with Etheruem on a ZK rollup16:10 Pricing opcodes 19:33 Walking through a transaction on the zkEVM under the hood25:38 Bottlenecks with data availability & the sequencer30:50 Progressively decentralizing the sequencer34:39 LX <> LY bridge design39:48 Tradeoffs of being fully EVM compatible49:46 Retaining parity with the EVM as the EVM introduces changes52:23 What should people build on the zkEVM?Learn about the Polygon zkEVM here: https://wiki.polygon.technology/docs/zkEVM/develop/Jordi on Twitter: https://twitter.com/jbaylina

A Deep Dive on StarkNet with Henri Liuetad
Today’s guest is Henri from StarkWare. Henri is a dev advocate who is deeply plugged into the StarkNet ecosystem and also hosts the StarkNet team’s podcast. This episode is meant to be a great introduction into building on StarkNet for existing web3 devs. We went very deep into all things StarkNet and Cairo. We discussed things like the StarkNet account model & runtime environment, the evolution of Cairo & Cairo 1.0, and the future of applications that might use StarkNet for privacy preserving applications (rather than using the ZK rollup for scalability alone).We also made sure to talk through the mental models that devs coming from the EVM need to understand in order to build on starknet, and why the team built their own separate language in the first place.Shownotes:00:00 intro3:15 How Henri got into crypto6:05 What is StarkNet?10:41 STARKS v SNARKS15:54 Walking through a StarkNet transaction19:05 Decentralization19:58 StarkNet account model23:22 Mental models EVM devs should understand to build on StarkNet29:34 What will people build on StarkNet?33:30 Building a privacy preserving application on StarkNet37:12 Cairo41:28 Evolution of Cairo and Cairo 1.044:52 Building secure products in Cairo49:15 Validity rollups & data availability56:20 What *should* people build on StarkNet?58:58 Henri’s long term view on the industryStarkWare Base Camp: https://twitter.com/StarkWareLtd/status/1605519238038294529Henri: https://twitter.com/henrlihenrliStarkNet: https://starkware.co/starknet/

Account Abstraction, ERC 4337, & Biconomy with sachint.eth
Today’s guest is Sachin from Biconomy. This episode was dedicated to the details of account abstraction and new technologies that aim to improve the overall user experience in web3. In particular, we went into great detail on ERC4337 vs EIP 3074, and talked through what infrastructure is required to actually get ERC 4337 implemented. Biconomy is working pretty aggressively on this, so we got a first hand perspective here. We also dove into some of the second order effects of ERC 4337 - such as how the user operation pool will work and whether or not this will open up new forms of front running outside of traditional MEV. If you’re a dev that wants to be on the forefront of new developments in account abstraction, then this episode is for you.If you're looking for a hackathon this month, check out the Superfluid Wave Pool: https://superfluid.finance/wavepool00:00 Intro3:45 how Sachin got into crypto13:44 ERC4337 v EIP 307429:58 Infrastructure for ERC 433745:29 Idiosyncrasies of the user operation pool with ERC 433747:20 Fixed gas transactions52:10 Supporting smart contract wallets on front end with biconomy1:03:45 How has Sachin approached improving as a dev?1:09:30 How does Sachin see the industry evolving?Sachin on Twitter: https://twitter.com/schin_tomarERC 4337: https://eips.ethereum.org/EIPS/eip-4337Biconomy: https://www.biconomy.io/ Fixed Gas Tx: https://mirror.xyz/0xd96FA162b064553822e765545E3D48a054eC81F6/PgRtcrT3CGN7sc723-2ykpXnAqQEJCMMtiLTL47ZFMQ

Igor Yalovoy - Founding a DeFi Protocol, Unlimited Contract Sizes, & Solidity Best Practices
Igor has a really interesting story. Babylon was a DeFi protocol that ended up shutting down after the Rari capital exploit, but the team gave the project a high integrity effort and it sounds like they learned many things during the journey.Igor walks us through what it was like launching a new DeFi protocol during the bull market, and also talks us through the lessons he took away from the experience. We cover subjects like testing smart contracts, preparing for audits, optimizations he’s product of, solutions to the sometimes oppressive contract size limit in solidity, & how he personally levels up as a solidity dev.This ep is a treasure trove of information for DeFi founders and technical folks.0:00 Intro1:30 Who is Igor?4:12 how Igor got involved in crypto8:55 Early technical decisions with Babylon [decent soundbite here on audits]13:44 Advice on testing composable systems16:05 Advice for people about to launch a defi protocol [cost of solidity soundbite at 15:10 or so..probably winning soundbite]19:45 Tooling Igor wishes people built for the space [soundbite on what to build] [gives a shoutout to defender around 20 min]27:33 The perils of the solidity contract size limit (and potential solutions)37:22 How to approach gas optimizations [decent soundbite there on how to handle this] [39 min a good one]41:12 Preparing for audits45:12 Favorite optimizations50:48 How has Igor approached leveling up as a solidity dev?
