Beyond the Code

This episode is with Anna George, co-founder & CEO of CowSwap / Cow Protocol (originally built inside Gnosis, spun out in 2022). What’s wild is Anna spent about a decade in humanitarian/UN work before getting pulled into crypto in 2017 - partly because she wanted impact, and partly because UN bureaucracy will make anyone want to run away and build something. We talk about the real CowSwap origin story: the early DEX experiments that didn’t work (including six-hour auctions… lol), the liquidity chicken-and-egg problem, and how CowSwap finally hit product-market fit with intent-based trading, MEV protection, and “you only pay gas if the trade actually executes.” We also cover where they’re going next: cross-chain swaps that don’t feel like bridging hell, deeper DeFi integrations (including Aave), and a bigger push to make crypto UX not terrible.

In this episode of Beyond the Code, Yitzy sits down with David Alexander “Alex” Scheer, founder and CEO of zkMe, a zero-knowledge identity network that lets users prove who they are - and meet KYC/AML requirements - without exposing their personal data. zkMe builds identity oracles that turn existing credentials (passports, bank accounts, credit scores, tax records and more) into reusable, privacy-preserving proofs using zero-knowledge technology. Alex shares how a career that started in mechanical engineering and aerospace, moved through automotive supply-chain consulting and software, and eventually led him to Shanghai, MiCA, and the decision to jump head-first into decentralized identity. We dig into why MiCA’s early drafts convinced him that Web3 would need a decentralized identity primitive to survive, and how zkMe is now serving millions of verified users while staying fully privacy-first and compliant. Together we unpack what zero-knowledge proofs actually are (in human language), why Alex thinks ZK is more foundational than blockchains themselves, and how zk-based KYC can both meet FATF-level requirements and keep users pseudonymous until regulators really have grounds to pierce the veil. We explore the tension between regulators who are increasingly open to ZK approaches and compliance officers who’ve done things the same way for 40 years, as well as how stablecoins, self-custodial wallets and secondary markets are forcing a rethink of identity and risk.From open banking ZK credentials and under-collateralized lending, to AI agents, the “machine economy,” and the business model behind decentralized compliance, Alex explains where zkMe is growing next and why he sees ZK identity as an anti-cyclical bet on crypto’s regulated future.

In this episode of Beyond the Code, Yitzy sits down with Danielle Tichner, founder of W Source, a deep-tech venture builder operating at the intersection of infrastructure, crypto, and global commercialization. Danielle shares her journey from a red-headed, left-handed, dyslexic kid trying to “fit in” to becoming a top negotiator at Philips Electronics and then building her own firm that helps complex technologies actually reach real markets.We dive into what “deep tech” really means, how W Source evolved from cross-border hardware advisory into software, crypto and full-blown venture building, and why Danielle only wants to work on hard, complex problems. From decentralized vault infrastructure like Lagoon to the emerging world of Bitcoin layer-2s (RGB, OP_CAT and more), she breaks down what she’s excited about, how she evaluates teams and tech, and why most projects underestimate go-to-market far more than they underestimate code.The conversation also detours into negotiation as an art of “perceived win-win,” cultural nuance in Asia and beyond, how to actually get value out of crypto conferences, and closes with Danielle turning the mic on Yitzy to ask whether our future will be governed by regulators or by code.Find Danielle on:LinkedIn: https://www.linkedin.com/in/danielletichner/X: https://x.com/danielletichner

EY’s Global Blockchain Leader Paul Brody joins Yitzy on Beyond the Code to peel back the curtain on how big companies really operate (“chaos on the inside”), why public blockchains beat private networks, and what it takes to ship serious enterprise workflows on Ethereum. We trace Paul’s zig-zagging path—Nigeria during a coup, Apple’s textbook S&OP, a Samsung prototype with a young Vitalik—to EY’s privacy stack (Nightfall/Starlight) and his “pragmatic ETH-maxi” thesis.

In this episode, Yitzy is joined by Yehuda Lindell—founder of Unbound Security (acquired by Coinbase), longtime professor and one of the earliest researchers in secure multiparty computation (MPC). We trace his journey from Australia to Israel and from theory to industry, then dive into how Coinbase secures customer assets using layered cryptography: MPC, secure enclaves, HSMs, cold elements, and rigorous review processes. Yehuda explains MPC in plain English (with a great DNA example), why “defense-in-depth” beats any single fortress, how insider threats are modeled, and what Coinbase’s production bar looks like. We also talk CS education in the age of AI, and why students should learn to program with AI rather than fear it. Yehuda closes with a pointer to CB-MPC, Coinbase’s open-source MPC engine, and a broader call for rigor when turning cryptography papers into production systems.Resources and Links:Yehuda on LI: https://www.linkedin.com/in/yehudalindell/ Yehuda on X: https://x.com/LindellYehudaCoinbase's CB-MPC library: https://github.com/coinbase/cb-mpc Timestamps:00:00 — Intro & Yehuda’s background05:43 — What is cryptography (for non-experts)16:00 — MPC 101 (privacy, correctness, shard thresholds)19:36 — Real-world key splitting; surviving full IT compromise23:38 — Coinbase’s defense-in-depth philosophy24:34 — What secure enclaves are (and side-channel realities)28:52 — Cold elements, cross-domain guards, layered participants31:31 — Coinbase’s production bar & independent reviews35:54 — CS, AI, and training “with” AI41:59 — CB-MPC and parting advice
