Privacy is having a moment in crypto. As competition heats up, the pitfalls of the technology around the quantum threat, regulatory risk and more make the trajectory hard to predict. A counterfeit bug sat undetected in Zcash's Orchard privacy pool for four years, capable of minting an unlimited supply of untraceable coins, illustrating the risks of one of the hottest crazes in crypto. Joe Andrews, CEO of Aztec Labs, Jarrad Hope, founder of Logos, and Mert Mumtaz, cofounder and CEO of Helius, join Laura Shin to argue the bug is less alarming than what it reveals: cryptographic privacy is difficult to get right, and the industry is racing to get it right anyway, because institutions will not come onchain without it. They cover Zcash's quantum-recoverable Ironwood upgrade and the turnstile proving the counterfeit coins never moved, Ethereum's sprawling privacy roadmap and the risk it arrives too late, Logos' mixnet built to protect validators from block relays now censoring transactions, and why all three see Canton's private stablecoins as little more than a bank with extra steps. The fight over what actually counts as privacy on a blockchain is only getting started.

Mert and Illia autopsy a brutal weekend in crypto: Saylor's $3M test sale that taught him there's no sell button, the Zcash bug Claude found that could've minted unlimited counterfeit ZEC, formal verification as the bulwark against AI attackers, and whether NEAR's agentic commerce vision is real. Welcome to The Chopping Block — where crypto insiders Haseeb Qureshi, Tom Schmidt, Tarun Chitra, and Robert Leshner chop it up about the latest in crypto. This week we've got two heavy hitters: NEAR Protocol co-founder Illia Polosukhin and Helius founder Mert Mumtaz. We kick things off with the weekend market meltdown -- Saylor sold 32 BTC for the first time in four years, STRC is trading below par, and Mert argues the real damage is that Saylor sucks all the air out of the room for actual crypto innovation. Then we get into the biggest story of the week: a critical bug discovered in Zcash's Orchard ZK circuit using Claude Opus 4.8 that could have allowed infinite counterfeit minting inside the shielded pool. Mert walks us through the emergency soft fork, the Ironwood migration, and why formal verification is about to become table stakes. Illia makes the case that AI-powered attackers have a permanent asymmetric advantage and that we need real-time on-chain detection systems to survive. Tom coins the analogy of the episode: we're moving from building boats to building spaceships. We close with Illia's pitch for NEAR's agent commerce vision – $240M in single-day volume, private intents, and the claim that agent-to-agent trustless commerce is already live – while Mert remains a friendly skeptic. Let's get into it. Listen to the episode on Apple Podcasts, Spotify, Pods, Fountain, Podcast Addict, Pocket Casts, Amazon Music, or on your favorite podcast platform.

Zcash is having its first real narrative moment in years. David sits down with Multicoin Capital co-founder Tushar Jain and Mert Mumtaz to unpack why privacy may be crypto’s missing store-of-value primitive, why Zcash is being framed as “private Bitcoin,” how institutional adoption could normalize shielded money, what AI and onchain surveillance change about the privacy debate, and why quantum risk could become a real catalyst. --- 📣SPOTIFY PREMIUM RSS FEED | USE CODE: SPOTIFY24 https://bankless.cc/spotify-premium --- BANKLESS SPONSOR TOOLS: 🔮POLYMARKET | #1 PREDICTION MARKET https://bankless.cc/polymarket-podcast 🟦 COINBASE ONE | MEMBER MONTH https://bankless.cc/coinbase-one 🧭OKX | TRADE, EARN, PAY to OKX | 120M+ USERS WORLDWIDE https://app.okx.com/join/USBANKLESS 🦊 METAMASK | DOWNLOAD NOW https://go.metamask.io/BL-Pod-Download 🌐BRIX | EMERGING MARKET YIELD https://bankless.cc/brix 💰NEXO | Get your 30-day access to Wealth Club Premier https://bankless.cc/nexo --- TIMESTAMPS 0:00 Why Multicoin Got Interested in Zcash 5:22 Mert’s Path from Solana to Zcash 9:57 Why Zcash, Why Now? 17:01 The Institutional Path for Private Money 22:03 Zcash as a Private Store of Value 25:27 Fungibility, Tainted Coins, and Financial History 27:26 The Bear Case: Does Anyone Really Care About Privacy? 34:43 Onchain Surveillance and Government Power 39:13 Zcash Tokenomics and the Forgotten Coin Thesis 44:58 The Last PVE in Crypto 50:17 Zcash and the Quantum Threat 59:14 Shielded Pool Growth and Upcoming Catalysts --- RESOURCES Tushar Jain https://x.com/tushar_jain Mert Mumtaz https://x.com/mert --- Not financial or tax advice.

Welcome to The Chopping Block — where crypto insiders Haseeb Qureshi, Tom Schmidt, Tarun Chitra, and Robert Leshner chop it up about the latest in crypto. This week, Helius’s Mert returns to defend Zcash’s ~400% run and the “encrypted Bitcoin” framing, digging into anonymity sets, privacy UX, and why Bitcoiners are so riled up. We then tackle the Tempo bombshell — a ~$500M raise at a ~$5B pre, Stripe/Paradigm ties, Dankrad’s move from the EF — alongside Péter Szilágyi’s letter on EF culture and compensation: public goods priesthood vs. market incentives. Next up: Mert’s “USD Manlet” rethink (why coordinating Solana around one stable is hard, and why pushing USDT to compete with USDC may be the sharper play) plus a gripe-fueled tour of today’s DeFi trading UX. Finally, an AWS-outage autopsy: Coinbase downtime, Base sequencer hiccups, Infura/MetaMask ripple effects, and the case for multi-region/multi-cloud redundancy when real money — and sometimes safety — are on the line. And no, despite the memes, Mert is not launching a DEX.

2024 has been a transformative year for Solana. With a surge in developer activity, bold innovations in DePIN, and its ambitions to become a “decentralized Nasdaq,” the ecosystem is making waves. But are these changes enough to differentiate it from competitors like Ethereum and L2 solutions such as Base? In this episode, Lily Liu, president of the Solana Foundation, and Mert Mumtaz, CEO of Helius, join Unchained to discuss how Solana is carving out its niche. They debate whether Base is a serious contender, why they’re not concerned about the 2025 token unlocks, and how Solana’s unique approach to MEV could shape its future. Plus, they tackle the ecosystem’s broader challenges and why they believe Solana’s vision will endure. Show highlights: Why Mert feels paranoid but also vindicated  Why Lily started working on Solana after being known as a hardcore bitcoiner How Mert’s background in Coinbase led him to found Helius and become the voice of Solana online Whether Solana can become a place where unique innovations are built, rather than copying Ethereum Whether Solana can achieve its vision of a “decentralized Nasdaq” Why the ecosystem has attracted so many developers in 2024  Why Lily believes that Base is no competitor to Solana What network extensions actually mean, according to Mert How Mert responds to the criticisms around Solana’s MEV Why Mert and Lily are not worried about the token unlocks of 2025 How the Solana mobile phone will compete with the giants Why DePIN showcases the real value of blockchain technology Visit our website for breaking news, analysis, op-eds, articles to learn about crypto, and much more: unchainedcrypto.com Thank you to our sponsors!
