    Interview: ZKLink - Vince Yang

    Interview: ZKLink - Vince Yang

    How ZK Is Shaping Blockchain

    • Guest: Vince Yang, Founder of ZKLink
    • Host: Szabolcs Gergely, Podcast & YouTube Host at Morningstar Ventures


    Top 3 Key Takeaways:

    1. ZK Proof has two significant components; Validator and Prover

    The conversation started with the topic of security. ZK Proof is looked at as an extra layer that is supposed to keep our privacy and, in the meantime, make underlying actions easier. When we asked Vince about the safety of ZK, he stated that ZK is a bulletproof layer that is mathematically proven to have high security. He explains that ZK Proof has two significant components: 

    1. Validator: This is based on the information of the proof that validates the existence of what is claimed to be there
    2. Prover: Bringing proof of the underlying tech. 



    2. DeFi needs to become more intuitive and comprehensive for day-to-day users

    Vince explained that the primary focus of zKlink is the blockchain. Specifically, the segment which needs to upgrade most is DeFi. Since DeFi is unintuitive and complicated for most day-to-day users, many tend to go to CEX solutions to complete their transactions, this needs to change. zKLink builds a layer on top of DeFi applications that offers CEX UI and UE for users who can transact and trade on DeFi using their wallets without giving up the ownership of their assets. 



    3. Make sure to understand what happens to your assets when you place them on a platform

    Toward the end of the conversation, we asked Vince how zKlink proves the security and the ownership of the assets. Vince answered, "When you place your assets on a platform, do you always know what is happening in the background?” The answer, of course, is that you don’t know. Therefore the team organized a massive campaign called Dunkirk, where they simulated a system shut-down, where every user had to try and withdraw their assets from the platform to prove that with this infrastructure, even if there is a system failure, everyone's assets are safe and can be withdrawn to their wallets, unlike on any CEX at this moment.

    Episode 213: zk-SNARKs meets Optimistic Rollup with Zkopru

    Episode 213: zk-SNARKs meets Optimistic Rollup with Zkopru
    This week Anna (https://twitter.com/AnnaRRose) chats with Wanseob Lim (https://twitter.com/wanseoblim) an Applied ZKP Developer in the Privacy & Scaling Exploration Team at the Ethereum Foundation and one of the authors of the Zkopru protocol (https://zkopru.network/). They explore how Zkopru uses optimistic rollups and zero knowledge proofs to create a privacy-focused Layer 2.

    Episode 54: Digging into recursive zkSNARKs with Coda

    Episode 54: Digging into recursive zkSNARKs with Coda
    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. To find out more about the project and some of the resources mentioned in the episode, please have a look at the links below: Coda on Twitter: https://twitter.com/codaprotocol?lang=en Coda on Github: https://github.com/o1-labs Scalable Zero Knowledge via Cycles of Elliptic Curves https://eprint.iacr.org/2014/595 Incrementally Verifiable Computation or Knowledge Implies Time/Space Efficiency https://pdfs.semanticscholar.org/4074/97eeb99a9341714e9db05b57f500270139d7.pdf Thank you to our sponsor POA Network (https://poa.network/) - for more information about their ERC20 to ERC20 TokenBridge, check out the POA Network repo: github.com/poanetwork/token-bridge Follow Zero Knowledge on Twitter - @zeroknowledgefm (https://twitter.com/zeroknowledgefm) Support us on Patreon - https://www.patreon.com/zeroknowledge Or directly here: ETH: 0xC0FFEE1B5083230a5154F55f253B6b6ae8F29B1a BTC: 1cafekGa3podM4fBxPSQc6RCEXQNTK8Zz

    Episode 50: Zooko talks Zcash on our 50th episode

    Episode 50: Zooko talks Zcash on our 50th episode
    In this special 50th episode, we invite our friend Zooko to the podcast to chat about his background and explore the history of Zerocoin and Zcash. We dig into the inner workings of Zcash, the trusted setup, the sapling upgrade, and what the future of the project might look like! The Sapling upgrade promises to reduce the proving times of the zk-SNARKs from 37 seconds to 2.3 seconds by replacing the SHA256 hash function with an improved performance Pedersen hash function called Bowe-Hopwood Pedersen, introducing an updated eliptic curve (Groth16/BLS12-381), moving from Libsnark to Bellman, and using a new split circuit design. We dig deep on this and into what the UTXO model actually is to help us better understand the changes being introduced with Sapling. Hope you enjoy coming on this journey with us!
