    Episode 169: Arkworks SNARK libraries with Pratyush Mishra

    Episode 169: Arkworks SNARK libraries with Pratyush Mishra

    In this week’s episode, Anna and Robert Habermeier chat with Pratyush Mishra, co-author of the Arkworks toolkit. Arkworks is a collection of Rust libraries designed to simplify development with SNARKs, both for developing high-level application circuits and building custom SNARK implementations.


    Pratyush lays out what possibilities and trade-offs Arkworks offers, diving into the details of the Rust implementation and why it is the best language for developing cryptographic primitives. Anna, Rob and Pratyush then branch out into the philosophical and practical questions of open-source and blockchain development.


    Here are a few links to Arkworks and the topics they discussed:


    Arkworks GitHub page and Telegram group.


    Pratyush’s GitHub, Twitter and Berkeley pages.


    Bellman and Libsnark, some of the other libraries that are similar to Arkworks.


    The Celo and Mina protocols, two major projects using Arkworks.


    Here is a basic explainer of what projects like Arkworks are trying to do and why it’s useful, with a particular focus on ZoKrates, one of the languages Pratyush mentioned.


    Intros to Circom, Leo and Zinc, some of the higher level languages.

    Episode 168: Flashbots with Phil Daian and Stephane Gosselin

    Episode 168: Flashbots with Phil Daian and Stephane Gosselin

    In this week’s episode, Anna and James Prestwich chat with Phil Daian and Stephane Gosselin from the Flashbots project. Flashbots is a research and development organization formed to mitigate the negative externalities and existential risks posed by miner-extractable value (MEV) to smart-contract blockchains


    They talk about the Flashbots organization and mission as well as the evolving opportunities and dangers lurking in the mempool.


    Miner extractable value (MEV) is a measure devised to study consensus security by modeling the profit a miner (or validator, sequencer, or other privileged protocol actor) can make through their ability to arbitrarily include, exclude, or re-order transactions from the blocks they produce.


    Here are some links to previous episodes, the project & MEV:

    Episode 165: Aave with Stani Kulechov

    Episode 165: Aave with Stani Kulechov

    This week, Anna and Tarun chat with Stani Kulechov, co-founder of Aave, about the origin and evolution of the project, the changing DeFi landscape, collateralized debt in crypto, Flash Loans, Flash Minting, Credit Delegation and the future of DeFi.


    Quick recap: A Flashloan is an uncollatoralised loan which must be issued and repaid in the same transaction before the blockchain updates the user’s account balances. If it isn’t repaid in this time, the transaction will fail.


    We have discussed Flashloans on the show before see this previous episode:

    Thank you to this week’s sponsor Hermez Protocol!


    Hermez is a Layer 2 solution that scales token transfers on top of Ethereum and which can handle up to 2000 transactions per second. Designed for high-frequency tokens, Hermez is a zk rollup which leverages zk-SNARKs for validity proofs and with on-chain data availability.


    Hermez's zero-knowledge circuits are developed using iden3’s circuit compiler language, Circom. 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. Learn more about the project and bug bounty at https://hermez.io/

    Episode 164: The road to Skynet & beyond with David Vorick

    Episode 164: The road to Skynet & beyond with David Vorick

    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.
