This week Anna (https://twitter.com/AnnaRRose) and James (https://twitter.com/_prestwich) chat with Elena Nadolinski (https://twitter.com/leanthebean), 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.

In this week’s episode, Anna (https://twitter.com/AnnaRRose) chats with Zac Williamson (https://twitter.com/zac_aztec) and Joe Andrews (https://twitter.com/jaosef), respectively CTO and Head of Product at Aztec. The episode is centered on Aztec’s latest release, zk.money, the “zk-zk-rollup” that targets privacy and scalability at the same time. zk.money allows users to shield their Ethereum-based assets while achieving a higher transaction count, a result that took months of research and development of the TurboPLONK. Zac and Joe explain how it works down to the nitty-gritty of elliptic curve arithmetic, logic gates, hashes and circuits. The conversation then shifts to topics like WebAssembly (and its limitations), Ethereum, UltraPLONK, Noir & more.

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 (https://kohweijie.com/) from the Ethereum Foundation (https://twitter.com/ethereum), Thomas Walton-Pocock (https://twitter.com/trpocock) from Aztec Protocol (https://twitter.com/aztecprotocol), Brecht Devos (https://twitter.com/Brechtpd) from Loopring (https://twitter.com/loopringorg) and Kobi Gurkan (https://kobi.one/) from the EF and cLabs (https://celo.org/). 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 Setups https://www.zeroknowledge.fm/50 - Zooko speaks about the trusted set up at timecode 17:45 https://www.wnycstudios.org/podcasts/radiolab/articles/ceremony https://z.cash/technology/paramgen/ EF's Perpetual Powers of Tau https://github.com/weijiekoh/perpetualpowersoftau Semaphore Semaphore blog post (https://medium.com/@weijiek/release-announcement-semaphore-a-zero-knowledge-gadget-for-ethereum-5b671cd360d4) Semaphore Phase 2 Multi-Party Trusted Setup Participant Guide (https://hackmd.io/oja21FipQ5KhQcXeyuQWFQ) MACI (upcoming) https://github.com/appliedzkp/maci Aztec Protocol https://www.aztecprotocol.com/ignition/ https://ignition.aztecprotocol.com/ Loopring https://loopring.org/#/post/loopring-starts-trusted-setup-multi-party-computation-ceremony Tornado Cash https://medium.com/@tornado.cash/the-biggest-trusted-setup-ceremony-in-the-world-3c6ab9c8fffa https://ceremony.tornado.cash/ cLabs (upcoming) https://github.com/celo-org/snark-setup Check out the Zero Knowledge Youtube Channel (https://www.youtube.com/channel/UCYWsYz5cKw4wZ9Mpe4kuM_g?view_as=subscriber) and be sure to subscribe to get the latest videos from the Podcast, zkSummit and zkStudyClub!

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/AndréWeil Thank 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. The event will bring together some of the brightest minds in zero knowledge research from both the academic and application spheres. Topics that will be discussed are self-custodial trading, STARKs for Layer 1, STARK-friendly hash functions and other cool things you can do with STARK proofs.

In this week's episode, we sit down with Izaak Meckler & Evan Shapiro from O(1) Labs to discuss Coda, a blockchain using recursive composition of zkSNARKs to eliminate history. We discuss recursive zkSNARKs generally, what a recursive zkSNARK construction blockchain would look like, and the challenges in implementing this sophisticated scaling solution.

One of the key scalability challenges with public cryptocurrency blockchains is that their size grows linearly with the number of transactions. Mature blockchains such as Bitcoin and Ethereum contain >170GB and >1 TB of historical data respectively. New nodes joining these chains need to download this data and verify it in order to become a “full node”. The number of full nodes is a key measure of decentralization, and difficulty becoming a full node translates into future centralization. In this episode, we are joined by the duo of Evan Shapiro and Izaak Meckler, CEO and CTO at O(1) Labs respectively. O(1) Labs is a pioneering company that uses zkSNARK technology in order to construct a cryptocurrency blockchain, called Coda, that solves the blockchain size scalability bottleneck. New nodes joining the Coda network will be able to trustlessly boot up in under a minute by verifying cryptographic proofs that attest to the validity of the current chain. This technology has great potential to enable decentralization, and for one blockchain to be a light client of another blockchain. Topics covered in this episode: Scalability challenges of current cryptocurrencies Background on O(1) Labs and their mission statement How Coda uses succinct computational integrity technology (zkSNARKs) to enable further decentralization of blockchains Snarky – a domain specific language for zkSNARK computations Current state of Coda and roadmap Episode links: Coda protocol website Coda Whitepaper Presentation on Snarkly by Izzak Meckler zkSNARKs in a nutshell by Christian Reitweissner zkSNARKs in a nutshell by Vitalik Buterin Coda presentation at hack.summit("blockchain") 2018 This episode is hosted by Meher Roy and Sunny Aggarwal.
