Today’s guest is Richard Meissner, co founder & CTO at Safe. Richard is an expert on all things smart contract wallets, and we used this episode to go deep into account abstraction. In particular, we discussed the Safe contract architecture and how things like Safe modules & smart contract wallets work under the hood.

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

Today’s guest is DC Builder - a pseudonymous dev who works as an engineer at Worldcoin and maintains DevPill.me - a guide to becoming a web3 engineer.DC Builder has contributed quite a bit of open source content & research to the space as well. He’s written things like deep dive guides on L2s and he also created the zero knowledge machine learning community.In this episode, we got deep into the weeds on ZK ML (a fascinating topic I knew nothing about before this convo), becoming a web3 dev, and how to decide which communities and ecosystems to invest time into.This is a great episode for engineers looking to level up in the industry, and for anyone curious about ZK ML.00:00 Intro3:20 How DC builder got into crypto7:31 Bottom up vs top down learning9:17 From research to development13:45 devpill.me breakdown16:41 Advice for early web3 engineers118:48 How to evaluate new developer ecosystems?23:09 Leveling up as a developer27:39 ZK32: 28 ZK ML - a wild topic42:29 Using ZK for *interactions* with ML models47:44 Working at Worldcoin (ZK ML experiments and Worldcoin ID state bridge)56:33 Moving data from Polygon to Ethereum L11:03:43 Learning about how the EIP/ERC process works1:06:44 Building social capital in the industry1:12:54 Other things that DC builder is interested in1:15:53 What does DC Builder hope that our industry accomplishes?Learning how to learn: https://barbaraoakley.com/books/learning-how-to-learn/Blockchain Dev Guide: https://www.devpill.me/Awesome ZKML: https://github.com/worldcoin/awesome-zkmlDCBuilder on Twitter: https://twitter.com/DCbuild3r

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/

Today’s guest is DeGatchi, an anon web3 dev who has gone from teaching himself to code on the bus, to building some of the most cutting edge open source tooling in the space. In this episode, Degatchi walks us through his journey into crypto, and his work as a dev to date. We discussed his early learning process, and his journey doing things like launching a DEX, getting into MEV, and ultimately building cutting edge tooling like bytecode & calldata decoders. If you’re interested in some nuanced takes on MEV, understanding the EVM under the hood, and how you can dramatically increase your own rate of learning in the industry, this episode is for you.Shownotes:2:53 How DeGatchi got into crypto7:06 Importance of working with other good engineers8:50 Languages: learning solidity, rust10:15 The role of MEV for the industry13:55 Getting into MEV15:55 MEV terminology: long tail, short tail, generalized front-running21:11 Rust v Go for MEV23:20 Reverse engineering24:30 Building a call data decoder25:40 Bytecode decoder33:05 anon crypto dev culture35:55 People who have helped DeGatchi (0xBuns, Huff community, Flashbots discord, “cult” on fantom, etc)38:02 Zk interests39:32 Yield farming automation43:01 Other interests44:31 What other tooling does DeGatchi want to build?48:55 Advice for other early career devs51:10 What does DeGatchi hope the industry looks like in 10 years?DeGatchi on Twitter: https://twitter.com/DeGatchiDeGatchi's Blog: https://degatchi.com/

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
