Description

Zero Knowledge is a podcast which goes deep into the tech that will power the emerging Web3 and the community researching and building this. The podcast is made for fellow developers and people looking to educate themselves on the inner workings of the space.
We are non-speculative and focus on the tech.
Zero Knowledge is hosted by Anna Rose and Fredrik Harryson, two people working in the blockchain industry. Our views do not come from nor represent our companies.

In this episode, we chat with the Oleg Andreev, a protocol architect from Stellar, about zkVM, the zero-knowledge virtual machine. In this episode, we learn a little bit about the history of Stellar, Chain and the zkVM project. We touch on the general concepts of VMs as well as compare zkVM with some other zero knowledge protocols like ZCash and ZEXE.

We cover some of the latest innovations, some existing challenges, timelines, implementation challenges and more. We also touch on an article that Raul published about the Libra protocol, and talk about how it compares to the public blockchains we all know and love. You can find this here: https://www.tokendaily.co/blog/a-close-look-at-libra-s-source-codeFor some more info, please check out the following: * Our previous ZKP episode with Prysmatic Labs (https://www.zeroknowledge.fm/37)* Prysmatic Labs (https://prysmaticlabs.com/)* Saphire Testnet (https://alpha.prylabs.net/)Thank you to our sponsor this week Aragon One (https://aragon.one/).If you love working with talented designers building smart user interfaces, or if you are simply excited about working on making DAOs easy and accessible to create & manage, then you should check out Aragon One’s available jobs.

In this week’s episode, we chat with Ben Fisch, Stanford PhD student working in Dan Boneh's applied cryptography group. In our conversation, we dig into accumulators, Merkle trees & vector commitments. We also learn a bit about the RSA Accumulator Paper - entitled Batching Techniques for Accumulators with Applications to IOPs and Stateless Blockchains (https://eprint.iacr.org/2018/1188.pdf) - that he co-authored with Benedikt Bünz and touch on some of the ways these RSA accumulators could potentially be used in a blockchain context. Here are a few previous episodes that might help you prep for this interview: Merkle Trees https://www.zeroknowledge.fm/57MPCs https://www.zeroknowledge.fm/60Here are a few concepts and links we mention: Batching Techniques for Accumulators with Applications to IOPs and Stateless Blockchains (https://eprint.iacr.org/2018/1188.pdf)https://en.wikipedia.org/wiki/RSA_(cryptosystem)https://github.com/cambrian/accumulatorhttps://medium.com/@chia.net/chia-vdf-competition-guide-5382e1f4bd39Thank you to our sponsor this week StarkWare (https://starkware.co) StarkWare will be presenting the StarkWare Sessions (https://starkware.co/starkware-sessions/) - on Sept 16th in Tel Aviv.

This week, we chat with Will Harborne (https://twitter.com/will_harborne), co-founder of Ethfinex (https://trustless.ethfinex.com/) and previously at Bitfinex, about the path from traditional exchanges, to centralised crypto exchanges and more recently DEXs. We explore what the role of the DEXs really is and what we could imagine seeing in the future of the space. Some links and articles mentioned: * Ethfinex (https://trustless.ethfinex.com/)* Phil Daian's Flash Boys 2.0: Frontrunning, Transaction Reordering, and Consensus Instability in Decentralized Exchanges (https://arxiv.org/abs/1904.05234)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)Support our Gitcoin Grant (https://gitcoin.co/grants/38/zero-knowledge-podcast)Support us on the ZKPatreon (https://www.patreon.com/zeroknowledge)Or directly here: ETH: 0xC0FFEE1B5083230a5154F55f253B6b6ae8F29B1aBTC: 1cafekGa3podM4fBxPSQc6RCEXQNTK8ZzZEC: t1R2bujRF3Hzte9ALHpMJvY8t5kb9ut9SpQ
In this week’s episode, we welcome Ariel Gabizon, previously a Electric Coin Company (Zcash) engineer and now a cryptographer working on zero knowledge constructions for Filecoin (https://filecoin.io/). Ariel has worked closely with some of the most exciting projects and researchers pushing the boundaries on zero knowledge research. He is also the person who discovered the Zcash bug (along with Sean Bowe and Zooko). In this episode, we explore his journey into the space, what inspires him, and what exciting new paradigms he is exploring today! Here are some of the articles and topics he mentions: * Algebraic Methods for Interactive Proof Systems (https://users.cs.fiu.edu/~giri/teach/5420/f01/LundIPS.pdf)* ECC (Zcash) Vulnerability Blog post (https://electriccoin.co/blog/zcash-counterfeiting-vulnerability-successfully-remediated/) * https://en.wikipedia.org/wiki/BernhardRiemann* https://en.wikipedia.org/wiki/Riemannzetafunction* https://en.wikipedia.org/wiki/Algebraicfunctionfield* https://en.wikipedia.org/wiki/HelmutHasse* https://en.wikipedia.org/wiki/Hasseprinciple* https://en.wikipedia.org/wiki/AndréWeilThank you to our sponsor this week StarkWare (https://starkware.co) StarkWare will be presenting the StarkWare Sessions (https://starkware.co/starkware-sessions/) - on Sept 16th in Tel Aviv.
