This week, Anna catches up with Illia Polosukhin (https://twitter.com/ilblackdragon), CTO and co-founder of NEAR (https://near.ai/), to talk about what's new in the network since last year. They go deeper on some of the topics they discussed last time - such as sharded vs non-sharded blockchains and data availability as well as discuss the long and rocky road to launching a new PoS network, building a validator community and where we might see privacy and zkp tech in Near. Some episodes we reference in our chat. * Ep 91: Near Protocol's focus on UX (https://www.zeroknowledge.fm/91) * Ep 135: Look into Solana (https://www.zeroknowledge.fm/135) * Ep 156: Stateless Validation with Alin Tomescu (https://www.zeroknowledge.fm/156) Thank you to this week’s sponsor Trail of Bits (https://www.trailofbits.com/).

In this week’s episode, guest host Tarun Chitra (https://twitter.com/tarunchitra) and Anna chat with Alex Svanevik (https://twitter.com/asvanevik?lang=en), CEO & cofounder of Nansen (https://nansen.ai). 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).

Sushiswap Bonus Chat

Sushiswap Bonus Chat

2020-09-2409:17

This is a short bonus chat to Episode 148 "Tale of the Sushi(swap)". Tarun (https://twitter.com/sushiswap?lang=en), Hasu (https://twitter.com/hasufl) and Anna (https://twitter.com/annarrose) 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" (https://www.zeroknowledge.fm/148) "Tale of the Sushi(swap) - Part 2" (https://anchor.fm/uncommoncore/episodes/A-Tale-of-SushiSwap---Part-II-ek3o9d) 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 (https://twitter.com/sushiswap?lang=en), Hasu (https://twitter.com/hasufl) and Anna (https://twitter.com/annarrose) cover the emergence of governance tokens in the DeFi space and then dive deep into the Sushiswap (https://twitter.com/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 (https://anchor.fm/uncommoncore/episodes/A-Tale-of-SushiSwap---Part-II-ek3o9d).  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 (https://medium.com/@pintail/understanding-uniswap-returns-cc593f3499ef). A quick caveat: We recorded this episode just hours before the Uniswap token launch (https://cointelegraph.com/news/rise-of-defi-wars-uniswap-s-uni-token-airdrop-starts-a-crypto-rivalry), 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 (https://twitter.com/ramanvishwa?lang=en), Privacy Architect at Oasis Labs (https://www.oasislabs.com) 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 (https://medium.com/oasis-protocol-project) 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 (https://medium.com/oasis-protocol-project/oasis-labs-joins-forces-with-binance-to-launch-cryptosafe-alliance-and-decentralized-platform-for-1e3964d8531) where Oasis is the primary infrastructure builder. Here are some of the papers and links that we discuss: Oasis Labs at zkSummit ZK0x02 (https://www.youtube.com/watch?v=VIJSFc3Wom8&list=PLj80z0cJm8QEC-DUp0bvpy3p82kqfnvc-&index=7) Chorus: Differential Privacy via Query Rewriting (https://drive.google.com/file/d/1iA7uPfYuAE30M7yr0c6UVlYZlK1cye2F/view?usp=sharing) Towards Practical Differential Privacy for SQL Queries (https://drive.google.com/file/d/150H3NWdE-_gO8OYkUE3rwEK9gCXkhU4Z/view?usp=sharing) Problems with machine learning and privacy (https://drive.google.com/file/d/1DGulszw8a6lbKGs2O71p_nPc4XMdn3EV/view?usp=sharing) (one of many) Towards Practical Differentially Private Convex Optimization (https://drive.google.com/file/d/1AtxtG_5Ed0U4W6T3Fu-yLM7eu-5qIv9k/view?usp=sharing) One 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 (https://twitter.com/1howardwu) back to the show to share more about his new project Aleo (https://aleo.org/) - a privacy-focused blockchain that enables fully private applications. Howard's previous ZKPodcast episode, Introduction to zkSNARKs (https://www.zeroknowledge.fm/38), 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.

In this episode we chat with Josh Cincinnati (https://twitter.com/acityinohio), the former executive director of Zcash Foundation (https://twitter.com/ZcashFoundation). We cover Josh's career before Zcash, his work at the foundation, the important role privacy plays in crypto and the challenges of decentralised governance. We also discuss his decision to leave the foundation, Zcash Foundation's philosophy of transparency, his hopes for the future of the Zcash community, his next steps and why he thinks people in crypto may wanna take themselves a bit less serious and remember to have some fun!

In this episode, Anna and guest host Georgios (https://twitter.com/gakonst) chat with Hasu (https://twitter.com/hasufl), 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 1559 Here are some additional links: Research paper: A model for Bitcoin’s security and the declining block subsidy (https://uncommoncore.co/research-paper-a-model-for-bitcoins-security-and-the-declining-block-subsidy/) Analysis of EIP-2593 (Escalator) (https://insights.deribit.com/market-research/analysis-of-eip-2593-escalator/) Analysis of EIP-1559 (https://insights.deribit.com/market-research/analysis-of-eip-1559/) Thank 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.

In this week's episode, we chat with Brian Gu (https://twitter.com/bgu33), a student at MIT and creator of the Dark Forest (https://twitter.com/darkforest_eth) 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 (https://blog.zkga.me/announcing-darkforest) 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 (https://www.reddit.com/r/zkpodcast) and leave us some questions for the upcoming AMA!** In this week’s episode, Anna and guest-host / frequent guest Tarun Chitra (https://twitter.com/tarunchitra) catch up with Alex Evans (https://twitter.com/alexhevans), researcher at Placeholder Capital (https://www.placeholder.vc/). 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 (https://link.medium.com/xMuiCj6hc8) by Tarun and Alex Liquidity Provider Returns in Geometric Mean Markets (https://arxiv.org/abs/2006.08806) by Alex Evans Building Liquidity into Token Distribution (https://medium.com/balancer-protocol/building-liquidity-into-token-distribution-a49d4286e0d4) Black–Scholes model (https://en.wikipedia.org/wiki/Black%E2%80%93Scholes_model) Thank you to this week's sponsor Trail of Bits (https://www.trailofbits.com/). 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 Bits If you like what we do: Follow us on Twitter - @zeroknowledgefm (https://twitter.com/zeroknowledgefm) Join us on Telegram (https://t.me/joinchat/B_81tQ57-ThZg8yOSx5gjA) Catch us on Youtube (https://www.youtube.com/channel/UCYWsYz5cKw4wZ9Mpe4kuM_g) Give us feedback! https://forms.gle/iKMSrVtcAn6BByH6A Support our Gitcoin Grant (https://gitcoin.co/grants/329/zero-knowledge-podcast-2) Support us on the ZKPatreon (https://www.patreon.com/zeroknowledge) Or directly here: ETH: 0xC0FFEE1B5083230a5154F55f253B6b6ae8F29B1a BTC: 1cafekGa3podM4fBxPSQc6RCEXQNTK8Zz ZEC: t1R2bujRF3Hzte9ALHpMJvY8t5kb9ut9SpQ

In this episode, we dive deeper into Findora (https://twitter.com/findoraorg), 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.

It's shocking to me how little people are aware of the Sia Network as a decentralized cloud storage provider. It's working right now and it's awesome!
