This week, Anna & Tarun take an in-depth look into AMMs with Guillermo Angeris, a PhD student in Stanford who co-authored a number of papers on fundamental AMM properties. They chat about how his work on Optimization Theory and Inverse Design can be applied to a DeFi context, as well as his most recent paper deals with privacy in AMMs, effectively demonstrating how superficial attempts at making a private AMM are doomed. During the conversation, Anna, Tarun and Guillermo chat about why AMMs today are so revolutionary and unique in the financial world, and why their success can be explained by optimization theory and convexity. But AMMs also have a number of shortcomings like front-running and impermanent loss, where Guillermo’s PhD work may just help find the solution.Here are a few links for this episode:Zero Knowledge Episode 153, Monsters in the Mempool with Dan Robinson Zero Knowledge Episode 168, Flashbots with Phil Daian and Stephane GosselineGuillermo’s latest paper on the challenges of implementing private AMMsGuillermo and Tarun’s first paper on Uniswap and Constant Function Market Makers, formalizing their practical qualities.Other papers by Guillermo and Tarun analyzing the optimal fee and bonding curve of CFMMs.Zero Knowledge Episode 103, Exploring VDFs with Joseph BonneauGuillermo’s papers on optimization problems and inverse design.Check out the Cosmos Privacy & ZKP Showcase -> https://hopin.com/events/cosmos-privacy-zkp-showcaseAnd the Zero Knowledge Gitcoin Grant -> https://gitcoin.co/grants/329/zero-knowledge-podcastThank you to this week’s sponsor, Aave.

In this week’s episode, Anna has a one-on-one chat with Alex Ozdemir, a PhD student at Stanford researching formal methods, cryptography and distributed systems. Alex’s work is closely tied to the world of generalized computations within zero knowledge systems. He is one of the main developers of CirC, an infrastructure framework for building zero knowledge languages. In their conversation, Alex and Anna take a bird’s eye view of the current landscape of zk languages and libraries. Alex explains the history and current state-of-the-art of circuit-building tools, touching on libraries like Libsnark, Bellman and more comprehensive tools like Arkworks; hardware description languages like Circom; and the more dev-friendly family of RAM-register languages like ZoKrates, Pequin, Cairo, Leo and many more. Here, the race is still on as a number of academic and business-oriented teams grapple with limitations to memory access & performance given by zero knowledge proving systems.The latest Gitcoin Grants CLR matching program is live!

They also introduce a novel consensus algorithm, Proof-of-Donation, that gives 40% of each transaction fee back to Ethereum community projects as a donation, thereby supporting Ethereum development.After passing two security audits, Hermez is running a bug bounty program, offering up to 100 ETH to whoever discovers any critical vulnerabilities. We recently had Jordi Baylina, Technical Lead at Hermez, on the show for an interview - you can find that episode here.

This week, Anna and guest co-host James Prestwich chat with David Vorick from Skynet Labs about the scope and goals of the Skynet project. They discuss the journey from earlier work on Sia & distributed data to Skynet, SkyDB, and their idea for Recursive Content Monetization - a new model to pay online creators and content owners. They also chat about the SkyFeed project - a decentralised Twitter like project. In this part of the conversation, they explore how the decentralised community could potentially remove the harm done by the social chat algorithms, but also the potential impact - and danger - that fully decentralised systems can have. Here are some helpful links: https://siasky.net/https://sia.tech/https://support.siasky.net/article/nz6p6876e3-skynet-resourceshttps://blog.sia.tech/skydb-a-mutable-database-for-the-decentralized-web-7170beeaa985https://blog.sia.tech/skynet-the-future-of-nebulous-c9922eb53456https://joinmastodon.org/Thanks to this week’s sponsor Aave. Aave Protocol is an open source and non-custodial protocol where users can earn interest on deposits and borrow assets Aave Protocol also features access to innovative DeFi building blocks like Flash Loans.

In this week’s episode, guest host Tarun Chitra and Anna chat with Alex Svanevik, CEO & cofounder of Nansen. They cover crypto analytics, DeFi analytics as well as discuss the push and pull between a need for privacy and the need for blockchain transparency and data. Topics include: can DeFi and Privacy co-exist, how being aware of blockchain analytics could help people improve their opsec, the role of reputation in these systems, and, finally, how analytics in public blockchains may used as a novel marketing tactic (eg. when someone purposefully makes a big buy, knowing sophisticated traders are following their every move using these analytics tools and will see this as a signal to buy as well).Thanks to this week’s sponsor AleoAleo is the first platform for fully private applications.

This is a short bonus chat to Episode 148 "Tale of the Sushi(swap)". Tarun, Hasu and Anna reconvene to wrap up the story of Governance Tokens, Sushiswap and the Uniswap token distribution. Be sure to first listen to "Tale of the Sushi(swap) - Part 1" "Tale of the Sushi(swap) - Part 2" on the uncommoncore podcast If you like what we do, be sure to check out the Zero Knowledge Podcast Gitcoin Grant - CLR matching is happening now! https://gitcoin.co/grants/329/zero-knowledge-podcast

In this special podcast crossover episode, Tarun, Hasu and Anna cover the emergence of governance tokens in the DeFi space and then dive deep into the Sushiswap story - what protocols came before and how it performed a vampire attack on (what was at the time) a tokenless Uniswap. This story acts as a fascinating case study as well as a cautionary tale for moat-less protocols.This episode is the 1st of 2 parts, with the 2nd part airing on Hasu's Uncommon Core podcast. In this part, we cover the definition of governance tokens and the first half of the sushi swap story. Tarun also mentions "impermanent loss" in this episode. However this term has been called to "divergence loss" and you can read more about what it is here. A quick caveat: We recorded this episode just hours before the Uniswap token launch, and so we decided to produce an amendment section to tackle the aftermath of the launch and wrap up the story.

In this episode, we catch up with Vishwanath Raman, Privacy Architect at Oasis Labs where he works on privacy and confidentiality technologies for Direct to Consumer and Business to Business use cases. His interest and experience span formal methods, applied machine learning, security, and privacy. Vishwa got his PhD in Computer Science at UC Santa Cruz followed by postdoctoral work at Carnegie Mellon. The Oasis Network is a privacy-enabled blockchain platform for responsible data use. Using a combination of secure computing and privacy technologies, the Oasis Network enables data owners to take control of their data and treat their data as a digital asset via data tokenization. They provide privacy as a service and use secure enclaves and differential privacy in order build a platform for a responsible data economy.We dive into the way the Oasis system is architected for privacy, who the ideal customers are and what the use cases for this protocol is. We also chatted about some of the tradeoffs in using SGX as well as the recent Binance-led CryptoSafe Alliance announcement where Oasis is the primary infrastructure builder. Here are some of the papers and links that we discuss: Oasis Labs at zkSummit ZK0x02 Chorus: Differential Privacy via Query Rewriting Towards Practical Differential Privacy for SQL Queries Problems with machine learning and privacy (one of many)Towards Practical Differentially Private Convex OptimizationOne small correction: Vishwa mentions the number of Validators on Oasis as numbering in the hundreds, but upon checking, we were informed that the number of validators that will participate in the consensus committee at mainnet launch is 70-100.

In this episode, we invite Howard Wu back to the show to share more about his new project Aleo - a privacy-focused blockchain that enables fully private applications. Howard's previous ZKPodcast episode, Introduction to zkSNARKs, remains one of our most popular episodes to date! We chat about why you need programming languages for SNARKs, what it is like to switch from VC/Academia to being a founder and the two important things missing in web services, high programmability and true user privacy. The project enables private applications with both data privacy and functional privacy - where the nature of the program running and all activity remains private. It is based on the ZEXE protocol and Proof-of-Succinct-Work, from the Proof-of-Necessary-Work originally presented Joseph Bonneau & Akis Kattis For more info check out these additional links & episodes: Aleo Developer Preview IZexe: Decentralized Private Computation with Pratyush MishraZEXE paperProof-of-Necessary-Work with Akis Kattis (NYU)Thank you to this week’s sponsor Least Authority.

In this episode, Anna and guest host Georgios chat with Hasu, an independent crypto researcher focused on economics and security, about elastic block size proposals in both Bitcoin and Ethereum.They cover how Hasu found his way into research as well as the history of the block size BIPs that shaped the ecosystem as well as Ethereum’s EIP 1559Here are some additional links: Research paper: A model for Bitcoin’s security and the declining block subsidyAnalysis of EIP-2593 (Escalator)Analysis of EIP-1559Thank you to this week’s sponsor Trail of Bits.Trail of Bits found a bug in yVault that would have allowed an attacker to drain most (if not all) of the pool's assets. They quickly reported the bug to the yVault team and were able to secure the roughly $400K USD held in the system. This bug, which was thankfully caught, highlights the risk stemming from increased complexity caused by composition in the DeFi space. ‘Generally - DeFi composability is hard. For example, If you integrate multiple tokens, any one token could compromise the security of your entire platform. On the other hand, if you integrate multiple platforms, your protocol could suffer from complex interactions.If this is a relevant topic for you or the project you work on, reach out to Trail of Bits to arrange a security assessment, or sign up for their Ethereum security office hours.Here is a link to their blog post “Accidentally stepping on a DeFi lego” https://blog.trailofbits.com/2020/08/05/accidentally-stepping-on-a-defi-lego Contact them here: https://www.trailofbits.com/contact/If you like what we do: Follow us on Twitter - @zeroknowledgefmJoin us on TelegramCatch us on YoutubeRead up on the r/ZKPodcast subredditGive us feedback! https://forms.gle/iKMSrVtcAn6BByH6A Support our Gitcoin GrantSupport us on the ZKPatreonOr directly here: ETH: 0xC0FFEE1B5083230a5154F55f253B6b6ae8F29B1aBTC: 1cafekGa3podM4fBxPSQc6RCEXQNTK8ZzZEC: t1R2bujRF3Hzte9ALHpMJvY8t5kb9ut9SpQ Read transcript

In this week's episode, we chat with Brian Gu, a student at MIT and creator of the Dark Forest game. We chat about education, blockchain based games and what inspired his work on the Dark Forest game. We then dig into how this game creates an incomplete information game space by using zkSNARKs to create a “cryptographic fog of war” and more! As described on their blog, Dark Forest is an MMO space-conquest game where players discover and conquer planets in an infinite, procedurally-generated, cryptographically-specified universe.

** Be sure to visit our ZKPodcast subreddit and leave us some questions for the upcoming AMA!** In this week’s episode, Anna and guest-host / frequent guest Tarun Chitra catch up with Alex Evans, researcher at Placeholder Capital. They dive into the latest in DeFi, a topic that we don't cover too often, but has become hard to ignore. Specifically they discuss the emergence of liquidity farming, the difference between the zkresearch space and the DeFi space, some emerging concepts like AMM and Staking derivatives, and cover a recent report Tarun and Alex published together on the impact of staking derivatives on the security of PoS systems. Here are a few of the articles and links mentioned in the episode: What PoS and DeFi can learn from mortgage-backed securities by Tarun and AlexLiquidity Provider Returns in Geometric Mean Markets by Alex EvansBuilding Liquidity into Token DistributionBlack–Scholes modelThank you to this week's sponsor Trail of Bits. Upgradeable contracts are not as safe as you think. Architectures for upgradeability can be flawed, locking contracts, losing data, or sabotaging your ability to recover from an incident. Every contract upgrade must be carefully reviewed to avoid catastrophic mistakes. The GitHub App Crytic now includes a comprehensive suite of 17 upgradeability checks to help you avoid these pitfalls. This tool allows devs to stress test their upgradeable contracts as they go, saving time and potentially catastrophic headaches down the line. For more check out their blog post where they describe how to use this tool - https://blog.trailofbits.com/2020/06/12/upgradeable-contracts-made-safer-with-crytic/So thanks again Trail of BitsIf you like what we do: Follow us on Twitter - @zeroknowledgefmJoin us on TelegramCatch us on YoutubeGive us feedback! https://forms.gle/iKMSrVtcAn6BByH6A Support our Gitcoin GrantSupport us on the ZKPatreonOr directly here: ETH: 0xC0FFEE1B5083230a5154F55f253B6b6ae8F29B1aBTC: 1cafekGa3podM4fBxPSQc6RCEXQNTK8ZzZEC: t1R2bujRF3Hzte9ALHpMJvY8t5kb9ut9SpQ Read transcript

** Check out the ZKPodcast subreddit and share some comments/questions for our upcoming AMA **This week, we catch up with Benedikt Bunz and Ben Fisch, PhD students at Stanford, once again. In this episode, we dive deeper into Findora, a project that was co-founded by Ben (who is also the CTO) and where Benedikt works as the Head of Research. We look at what the Findora project is, discuss the "selective disclosure" concept at the heart of their constructions, explore the balance between transparency and privacy and describe what problems Findora aims to solve.

In this episode, we will be exploring StarkWare and DeversiFi’s collaboration - a Layer 2 STARK-powered exchange for Ethereum assets. Guests Tom Brand, product manager at Starkware, and Will Harborne, co-founder of DeversiFi, discuss the project, how it works under the hood and give us a glimpse into what they have planned for the future. We also look at how Validium, that is Layer-2 scaling solutions in which the validity of all transactions is enforced using zero-knowledge proofs, while data availability is kept off-chain, differ from other layer 2 scaling solutions like Plasma, Optimistic Rollup and zkRollup, and discuss the axioms used to quantify these differences.Here is some of additional material:Matter Labs Blog post defining ValidiumDeversifi Blog post about the collaborationStarkware's STARKEx explained At the beginning of the episode, Anna and Will also discussed their joint project ZKValidator which works on Cosmos, Polkadot and Kusama.

This week, Anna and guest host Tarun Chitra chat with Yan X Zhang, professor at SJSU, about math competitions, math education, how crypto is like alchemy and the Gasper paper - work Yan and his students collaborated on with the Ethereum Foundation. “Gasper” is a proof-of-stake-based consensus protocol, which is an idealized version of the proposed Ethereum 2.0 beacon chain. The protocol combines Casper FFG, a finality tool, with LMD GHOST, a fork-choice rule.Here are a few episodes and papers that we mention: Consensus Algorithms & HotStuff with Ittai AbrahamCombining GHOST and CasperAli Rahimi - NIPS 2017 Test-of-Time Award presentationAs mentioned in the intro, we looking for some help on the organisational front with some of the zk related projects - this Zero Knowledge Podcast, zkStudyClub, zkSummit and the zkValidator.If you are looking to connect with the ecosystem, learn more and work on zk research AND if you are very organised and have worked producing either events, content or generally organising people in the past, these roles might be interesting for you. Here are the 2 roles: 1) zkPodcast Support: Work with Anna & Fredrik on our zk-related projects (excluding the zkValidator) on a part-time basis. This would primarily involve coordinating podcast guest, scheduling and coordinating studyclub sessions, help organise events like the zkSummit, writing blog posts and managing social channels.

In this week's episode, Anna explores the state of trusted setups with 4 of the people who have recently coordinated and run trusted setups for different SNARK systems. She interviews Koh Wei Jie from the Ethereum Foundation, Thomas Walton-Pocock from Aztec Protocol, Brecht Devos from Loopring and Kobi Gurkan from the EF and cLabs. This episode covers the new generation of trusted setups and how the teams working on these are learning from each other and at times, even sharing parts of the trusted set up itself. As a primer, Trusted Setups are those events or ceremonies that one needs to perform to generate the parameters that can kick off SNARK based systems. It is an MPC - or multiparty computation - that involves a number of participants sequentially downloading software, running a computation that includes some randomness that they generate and re-uploading their result to be folded into the next participants computation. At the end of this process, there is a hidden parameter that is used to create the keys that are used to create proofs for private transactions, and to verify those proofs. These keys prove that a transaction is correct. Here are some helpful links about all the various trusted setups we mention:Zcash's Trusted Setupshttps://www.zeroknowledge.fm/50 - Zooko speaks about the trusted set up at timecode 17:45https://www.wnycstudios.org/podcasts/radiolab/articles/ceremonyhttps://z.cash/technology/paramgen/EF's Perpetual Powers of Tauhttps://github.com/weijiekoh/perpetualpowersoftauSemaphoreSemaphore blog postSemaphore Phase 2 Multi-Party Trusted Setup Participant Guide MACI (upcoming) https://github.com/appliedzkp/maciAztec Protocolhttps://www.aztecprotocol.com/ignition/https://ignition.aztecprotocol.com/Loopringhttps://loopring.org/#/post/loopring-starts-trusted-setup-multi-party-computation-ceremonyTornado Cashhttps://medium.com/@tornado.cash/the-biggest-trusted-setup-ceremony-in-the-world-3c6ab9c8fffahttps://ceremony.tornado.cash/cLabs (upcoming)https://github.com/celo-org/snark-setupCheck out the Zero Knowledge Youtube Channel and be sure to subscribe to get the latest videos from the Podcast, zkSummit and zkStudyClub!Signup for zkMesh Newsletter - a monthly newsletter focused on sharing resources about decentralised privacy-preserving technologies, privacy protocol development and zero knowledge systems research.Signup to get this delivered directly into your inbox -->> https://zkmesh.substack.com/ If you like what we do: Follow us on Twitter - @zeroknowledgefmJoin us on TelegramGive us feedback! https://forms.gle/iKMSrVtcAn6BByH6A Support our Gitcoin GrantSupport us on the ZKPatreonOr directly here: ETH: 0xC0FFEE1B5083230a5154F55f253B6b6ae8F29B1aBTC: 1cafekGa3podM4fBxPSQc6RCEXQNTK8ZzZEC: t1R2bujRF3Hzte9ALHpMJvY8t5kb9ut9SpQ

In this episode, we chat with Mark Tyneway who is a contributor on the Handshake project - an experimental peer-to-peer root naming system. We learn about this decentralised, foundation-free project, the issues of DNS, how Handshake plans on fixing this, how it differs from ENS, their unique airdrop process, what an Urkel Trie is, and more.
