Zero Knowledge

This week James and Anna chat with Ben Edgington, Lead Product Manager for Teku, an Eth2 client developed by ConsenSys. Ben recounts his story of the involvement with Ethereum 2.0 from the very early months of Serenity and Shasper, and how those were completely replaced by the Beacon Chain concept that resulted in Ethereum 2.0 as we know it. Ben then highlights what changed after Phase 0 launch: the simplification of Phase 1 & 2 , the rollup-centric roadmap and the upcoming Merge with Eth1.Here are some links for this episode:ETH2.0 Update With Danny Ryan, Zero Knowledge Episode 66Sharding Update With Prysmatic Labs, Zero Knowledge Episode 37Exploring Uniswap V3 and a Multi-L2 Future with Noah and Moody, Zero Knowledge Episode 185Math competitions, crypto as alchemy & Gasper with Yan Zhang, Zero Knowledge Episode 136Unwrapping Optimism with Ben and Mark, Zero Knowledge Episode 177Ben’s What’s New in Eth2 NewsletterBen’s and Vitalik’s annotated Eth2 SpecsDon’t forget to check out the ZK Jobs Board if you’re looking to connect and work with a talented team in crypto & zk land!

This week, Anna chats with Oskar Thoren and Sanaz Taheri-Boshrooyeh from Status to learn about their work on Waku, a decentralized messaging protocol incorporating zk-SNARKs for spam protection. Waku is the successor of Whisper, a messaging protocol that turned out to be too resource-heavy and vulnerable to spamming.Oskar and Sanaz explain how Waku V2 changes things, from ZKP-based spam protection to how its new networking system based on libp2p and Gossipsub can scale globally.Here are some links for this episode:Trusted Setup Ceremonies Explored, Zero Knowledge episode 133IPFS, Libp2p & Filecoin with Juan Benet, Zero Knowledge episode 106Status’s write-up on how Waku improves Whisper.Rate Limiting Nullifiers, Status’s post on how the zk-based spam protection works.Gitcoin Grants Round 10 is live!

This week Anna and Tarun host Noah Zinsmeister and Moody Salem to learn all about Uniswap and the recent Uniswap V3 deployment. Noah and Moody go through the history of Uniswap from its EF grant days to Unisocks, Uniswap V2 and now Uniswap V3 and its ranged liquidity model. They explain all the benefits as well as the potential drawbacks, and how the project plans to fix them in a likely indirect way. At the end the conversation shifts into a multi-L2 deployment future and how that may increase MEV, leading Tarun to make an unexpected realization.Here are some links for this episode:A Tale of Sushi(Swap) with Tarun, Hasu and Anna, Zero Knowledge episode 148Aping into DeFi and NFTs with Andy Chorlian and Tarun Chitra, Zero Knowledge episode 181CowSwap & DAO Tech with Gnosis’s Martin Köppelmann, Zero Knowledge episode 183Diving into Arbitrum's Optimistic Rollup, Zero Knowledge episode 179Unwrapping Optimism with Ben and Mark, Zero Knowledge episode 177Flashbots with Phil Daian and Stephane Gosselin, Zero Knowledge episode 168Uniswap V3 launch postVitalik’s Uniswap as an oracle proposalDon’t forget to sign up to the upcoming zkSessions on June 23rd!

This week Anna and James chat with Elena Nadolinski, founder of Iron Fish, about the new privacy network and what led her to this point.Elena recounts her journey into crypto, starting from AirBnB and falling into the rabbit hole of Ethereum hackathons, Solidity, and NFTs, eventually leading her to exploration of zero knowledge proofs for honest computation. This deep dive into SNARKs and Sapling led to the creation of Beanstalk, later Iron Fish, which aims to be the shielded pool for all other blockchain assets.Note: James is an investor in Iron FishHere are some links:Elena’s slides about Sapling from ZconIron Fish whitepaperHalo with Sean Bowe and Daira Hopwood, Zero Knowledge Episode 123Zexe: Zero Knowledge Computation with Pratyush Mishra, Zero Knowledge Episode 85Ariel Gabizon on his work with zkSNARKs, Zero Knowledge Episode 86Don’t forget to subscribe to the ZkMesh newsletter, aggregating all of the latest developments in ZK each month.

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.Here are some links for this episode:Paper on Zendoo and LatusLatus incentive scheme white paperJ.
