Robert de Groot and Web3 Privacy Now

Griff Green is back, about six months after his first appearance, and this time Jade and co-host Stefan Beyer get him talking about communal security and where TheDAO Security Fund has got to. Griff runs the fund, founded Giveth and DappNode, led the original DAO white-hat cleanup, and sits on the Arbitrum and ENS Security Councils. The line that sticks from this one: private keys are crypto’s original sin. Griff doesn’t hold back on it. It’s 2026, everyone’s been hacked, and the way we still onboard a new person is a raw private key and twelve seed words, where one bad click and it’s all gone. No bank works like that, because nobody would want it to. What he wants instead is vaults, smart-contract wallets, MPC setups like Turnkey (which Giveth now uses), things with daily limits, allowlists and an escape hatch if you get hacked. Non-custodial, but actually safe. He argues crypto could even be safer than a bank, because it can get rid of custodial risk entirely. First though, the fund. Round one handed out over $1.6M to 135 projects through quadratic funding, and the big lesson was how many people wanted to chip in for security, and how much they left on the table simply because they didn’t give themselves enough lead time to fundraise. So round two is built differently. Funding comes out against milestones, at least a third of every budget is tied to actual adoption, and an initiative has to raise 25% from the community before it can touch the DAO’s ~400 ETH. Then 200 Ethereum security badge holders vote on what gets funded using participatory budgeting (Stefan, to Griff’s disbelief, didn’t make the badge-holder cut). The whole design is about beating the free-rider problem: only fund the things the community actually puts money behind. The initiatives range from a privacy-preserving EDR tool to a service that screens job applicants for North Korean operatives. Then they get into the pound of cure. Griff walks through the KelpDAO exploit, how a LayerZero/RSETH issue let likely North Korean attackers borrow around $71M against duplicated collateral on Arbitrum, and how the Arbitrum Security Council stepped in with an L1 transaction to freeze it. He can’t discuss the internal debate (there’s an NDA), but he’s completely open about where he stands: on “code is law” versus stepping in, he’s an extremist, if you can stop North Korea walking off with $71M, you do it, every time. From there it widens out into the legal headaches that followed, why hackers now bridge funds off-chain to dodge exactly this kind of freeze, and a genuinely sobering stretch on how crypto’s weak security ends up funding real-world harm, from state actors to the scam compounds operating across Southeast Asia.

Title: The Quantum Threat, and Learning to Love It, with Colton Dillion & Dr. Richard Carback (Quip) Jade Doherty and Stefan Beyer speak to Colton Dillion and Dr. Richard Carback of Quip, the team building what they call the worldwide quantum computer. Quip is both a fix for the post-quantum problem and a marketplace monetising idle time on quantum computers, with quantum-resistant wallets that wrap existing ones on Ethereum, Solana, and a Bitcoin L2. The heart of the episode is the timeline. Rick walks through how Quip’s Quantum Doomsday Clock lands on roughly March 2028, the collision of two underestimated forces: exponential qubit growth and error-rate reduction, which has crushed the estimated requirement from 20 million qubits to IonQ’s claimed 20,000. Stefan presses on how much is hype versus real threat in a field as closed as the AI labs, and it turns genuinely unnerving: a quantum break is indistinguishable from any ordinary hack, there are 6-7 million vulnerable Bitcoin addresses (including two Binance wallets holding ~$20B), and Colton sketches a plausible attack where someone quietly drains old whale wallets, buys puts, then reveals Satoshi’s coins have moved. But why should you “stop worrying and learn to love the quantum.”? They make the case for defense-in-depth and hybrid signatures (where the fallback is never worse than today), why this is Y2K-like, a real deadline with no fixed date, likely a large no-op precisely because serious people are acting. They cover the roadmaps underway (Bitcoin’s BIP 360, Ethereum, Solana), looming government mandates, why insurance markets will price this before regulators, and the hard problem of upgrading not one chain but every bridge, oracle, and validator set. Rick is clear that Quip is not a privacy project and isn’t inventing exotic maths, deliberately using vanilla, battle-tested constructions, because, as Stefan notes, real-world losses come from operational mistakes, not broken cryptography. The episode closes on Quip’s products (the bridgeless QuipSwap protocol Oak audited, proof of useful work, a quantum randomness function) and the brighter side of quantum: chemical modelling, materials simulation, and one day simulating the universe.

Have you heard of Brave? Today we are joined by Kyle Den Hartog, a security engineer at the privacy browser. His path runs from penetration testing to self-sovereign identity to Web3, and that bridge between the Web2 and Web3 worlds runs through the whole conversation. They start with how Brave made privacy mainstream: sane defaults and treating privacy as an emergent property that has to be fought for at every layer, with surveillance capitalism as the threat model rather than Tor-style maximalism. From there, why the biggest problems are no longer smart-contract bugs but browser and interface attacks, and a sharp point about domain expertise: crypto wallet teams often don't realise the browser already solves their problems (MetaMask's phishing list vs Safe Browsing, Rabby leaking browsing history vs hash-prefixing). It's also why Brave built its wallet into the browser rather than as an extension. The most provocative stretch is Kyle's argument that Web3 is accidentally reintroducing cross-origin tracking. A wallet address is just a cookie: shared across sites on "connect," and far more revealing than any third-party cookie because it exposes where, when, and how much you spend. His fix is the thick client, moving transaction-building into the wallet so untrusted sites never receive the address. The conversation then ranges across why zero-knowledge proofs aren't the panacea they're treated as (the "20 questions" problem), how ZK-gated compliance can recreate the gatekeeping Web3 set out to escape, why the early internet's lack of an identity layer was a feature, and a thoughtful take on age verification. Kyle closes on what Web2 and Web3 get wrong about each other, and his practical privacy advice beyond switching to Brave: a reputable audited VPN, then moving off the platforms that track you most. Key Topics How Brave made privacy mainstream, and the browser as the real attack surface Why a wallet address is the new tracking cookie, and the "thick client" fix The limits of zero-knowledge proofs, identity, and getting age verification right Chapters 00:00 Introduction 00:35 From Penetration Testing to Self-Sovereign Identity to Brave 01:49 Making Privacy Mainstream: Sane Defaults and Emergent Privacy 04:34 The Brave Wallet, BAT, and Rethinking What the Infrastructure Is For 07:07 The Browser as Attack Surface: What Browsers Can Actually Do 10:06 Why Crypto Wallet Teams Miss What the Browser Already Solves 13:55 Why the Brave Wallet Is Built In, Not an Extension 16:02 Web2 Guy or Web3 Guy?

Jade Doherty and Stefan Beyer speak to Justus Hanna, co-founder and CEO of Grego AI, a bug bounty hunter turned founder building AI that finds vulnerabilities human auditors miss. Justus's path runs from hacking Novell networks as a kid, to Bitcoin in 2011, to picking up bug bounty hunting from scratch after a Wall Street layoff. The turning point came when his future co-founder showed him a system that found a high-severity bug in Lido's dual governance module, at a moment when every other AI bug hunter was producing pure slop. What sold him: the AI found bugs humans couldn't, faster and cheaper. He explains Deep Invariant Analysis as a proprietary harness orchestrating hundreds of specialised agents across many models, built to go five or six layers deep into complex systems and chain exploits a human would be very unlikely to reach. They tackle the big claims head-on: the $27.7M exploit prevented, the $250K bounty, why the protocol stayed unnamed, and the awkward truth that verifying an "AI-only" find still comes down to reputation. On the anxiety every auditor feels, Justus argues the harness is the moat, precisely because it's model-agnostic, and there's a candid detour on frontier-lab hype and safety theatre. The episode closes philosophically: his vision of an always-on "security operating system", and his advice to researchers, don't skip the manual apprenticeship. Learn the craft from first principles, then use AI as a superpower on top. Be Iron Man, not obsolete.

Jade Doherty and Stefan Beyer speak to Lorenzo Sicilia, Head of Technology at the Arbitrum Foundation, whose path into crypto runs through ConsenSys, Casval, and Outlier Ventures. They open with the distinction that shapes everything else: the Foundation is the steward and legal wrapper of the DAO, not the team behind the tech. Lorenzo unpacks how it ran the Arbitrum Audit Program on the DAO's behalf, vetting a shortlist of thirteen audit firms and funding early-stage teams, and gets into the hard parts with Stefan: the "rubber stamp" risk when a Foundation-blessed audit becomes a trust signal, the friction of re-auditing when each iteration costs $50K to $250K, and the brutal cost-per-line metric the program can now benchmark across firms. On security responsibility, Lorenzo is precise: the Foundation has none in the formal sense. Incidents fall to a 12-member Security Council, elected and rotated by the DAO. From there the conversation turns to what keeps him up at night, the L1-L2 trust boundary and the bridge, and why fraud proofs through BoLD have improved the picture, landing on his own preference for "code is law" while acknowledging where reality forces harder trade-offs. The technical heart is Stylus, Arbitrum's WASM environment for writing contracts in Rust alongside the EVM. Lorenzo is unromantic about it: a second runtime widens the attack surface, and while safe Rust has real advantages, no language removes the authorisation, economic, and oracle pitfalls that actually cause losses, treating any language as "safe" is a mental trap. The episode also covers the freshly-shipped ZK-on-BoLD upgrade, the road to real-time proving, and why AI currently hands the red team a big advantage over the blue team, though Lorenzo is optimistic defenders can turn the same tooling back on their own code. He closes with hard-won advice: authenticity and persistence over a polished demo, understand your oracles and dependencies, get key management right, and know when to switch from "fake it till you make it" to full paranoia, because in this industry, you don't get a discount. Key Topics The Arbitrum Audit Program, and the "rubber stamp" problem with Foundation-backed audits Decentralised security responsibility: the Security Council, the L1-L2 boundary, and BoLD Stylus and WASM security, ZK-on-BoLD, real-time proving, and AI's red-team advantage Chapters 00:00 Introduction 00:35 From ConsenSys and Outlier Ventures to the Arbitrum Foundation 04:11 What the Foundation Actually Does, and How It Differs from Offchain Labs 06:50 The Audit Program: How It Works and Who Funds It 10:18 The "Rubber Stamp" Problem and Vetting Audit Firms 13:18 Early-Stage vs Mature Teams: Who the Program Is For 14:54 What's Next: Additional Tools, AI, and the Limits of Scope 17:15 Lessons From the First Iteration, and Cost-Per-Line Benchmarking 21:11 The Foundation's Responsibility and the Security Council 24:49 What Keeps Him Up at Night: The L1-L2 Boundary and Bridges 29:16 Security Policy, Bug Bounties, and Disclosure Across the Ecosystem 30:48 Stylus: Does a WASM Runtime Widen the Attack Surface? 34:49 Safe Rust vs Solidity, Tooling Gaps, and the "Mental Trap" 39:13 Adding ZK to BoLD, and the Multi-Prover Approach 42:20 Real-Time Proving and Where Arbitrum Is Heading 45:20 ZK for Compression vs ZK for Privacy 46:24 AI in 2026: Red Team vs Blue Team, and AI Slop 50:31 Judging Teams: Authenticity, Resilience, and Real Problems 53:33 The Biggest Security Mistakes New Teams Make 55:25 The Foundation's Security Vision for the Next Few Years 57:52 One Piece of Advice: Dependencies, Keys, and Knowing When to Get Paranoid Resources and Links Lorenzo on X: https://x.com/aboutlo Arbitrum: https://arbitrum.io Oak Security's Research: https://research.oaksecurity.io/  

Jade and Stefan speak to Robert de Groot, a core contributor to Web3Privacy Now, the research collective and think tank behind the Cypherpunk Congress, and CFO at Gain. Robert starts from an unexpected place: privacy isn't really about hiding; it's about autonomy, the ability to choose what you reveal, to whom, when, and in what form. He connects it to something bigger than data leakage, the loss of the room to experiment and to fail, and the quiet self-censorship that creeps in when everything is recorded. From there the conversation opens onto the spectrum of privacy, from the journalist in a conflict zone who will work from a terminal if it keeps them alive, to the rest of us who just want a group chat that isn't intercepted and won't tolerate bad UX to get it. A big thread is the gap between personal privacy and business compliance, and why the two still don't align. Robert explains how Web3Privacy Now evaluates the 800-plus projects in its Explorer (the "hard variables," verifiable code over marketing claims), why "zero knowledge" and "private" have become marketing terms, and why privacy adoption lags even when the tooling is ready, the preventive-measure problem, the group effect, and cookie-banner fatigue. On the compliance side, he maps the middle ground: opt-in reporting, viewing keys, and selective disclosure (picking up the thread from our Jordi Baylina episode), including a one-time key you could hand your tax auditor and be notified when it's used.  He argues privacy will increasingly become a market-integrity feature, not just a civil-liberties one, shielding transaction amounts from competitors and MEV bots while keeping endpoints verifiable, and he closes on RWAs, why so many tokenisation projects quietly died on double-accounting overhead, and what "compliant by default" finally changes.

After several episodes focused on security, this one turns to privacy, with Emanuele Francioni, co-founder and CEO of Dusk, a blockchain built for privacy and institutional use cases. Emanuele traces the through-line from a contrarian 2018 thesis to a live network to abstract financial instruments away from the intermediaries that leak both value and data. A core thread is the counterintuitive relationship between privacy and regulation. He disentangles anonymity from confidentiality, shows how privacy actually underpins rules like GDPR, DORA, and insider-trading law, and explains how Dusk encodes KYC, jurisdiction, and limits directly into the protocol. Then it gets harder: on a privacy chain, a vulnerability can be exploited in the dark. Emanuele uses the recent Zcash unbounded-mint bug to explain why Dusk's approach has to be proactive, why the team shipped three security upgrades this year (Aegis and Boreas among them), and why simplicity is the best safeguard. On the AI arms race he's candid, seeing Fable in action for three days genuinely scared him, but his conclusion is pointed: AI doesn't replace security expertise; it makes it more valuable.

Most of our guests come at security from the outside, as auditors and researchers. Antonio Viggiano sits on the other side of the table: he's a Senior Security Engineer at the Monad Foundation, working on protocol fuzzing for the chain's consensus and execution clients. Monad's architecture makes that a genuinely different problem. Unlike Ethereum, with its many interchangeable clients, Monad has a single pair: a C++ execution client and a Rust consensus client, both built by Category Labs. That tight coupling buys optimisations, but it also means a bug that looks real in one client is often quietly mitigated by the other. Test one in isolation and you drown in false positives. That's where Monad Bugfinder came from, and the origin story is the opposite of what most people assume. It didn't start as a bug finder at all. It started as a triager, because the team was being flooded with AI-generated reports: convincing write-ups, plausible proofs of concept, and hours of human time spent working out which ones were real. Bug hunters optimise for recall. When you're the one receiving the reports, you need precision. Antonio walks through the validation gates that made the difference, why AI has a higher false positive rate than humans, and why the best human reviewers still find twice as many bugs as the best AI systems.

What does it actually mean to be "obsessed with AI for security"? In this episode of CypherTalk, Jade and co-host Stefan Beyer sit down with Prof. Arthur Gervais (UCL, affiliate faculty at UC Berkeley), known for foundational work on MEV, flash loan attacks, and AI-powered smart-contract security. Arthur's core conviction sets the tone: AI is not a zero-sum game. Strong researchers can now find vulnerabilities ten times faster, and the right response is to onboard everyone as fast as possible rather than lock the tools down. The conversation goes deep on A1, the agentic system his team built that turns any LLM into an end-to-end exploit generator with one unambiguous goal: generate a profit. The hard part, he stresses, isn't building it, it's target selection.   Key Topics AI for security enhancement AI-assisted vulnerability detection Real-time blockchain exploit detection   Chapters 00:00 Introduction to AI and Security 02:29 Arthur's Journey into Information Security 05:05 The Role of AI in Security 07:22 A1: The AI Agent for Exploit Generation 09:38 Autonomy and Ethics of AI Agents 11:53 Harnessing AI for Security Audits 14:15 The Evolution of LLMs and Their Impact 16:33 Dealing with False Positives in AI Security 19:06 The Academic Perspective on AI Research 21:42 Comparing LLMs for Security Tasks 24:05 Future Directions in AI and Security 25:26 The Power Dynamics in AI and Cybersecurity 29:04 Balancing Offensive and Defensive Strategies in AI 31:44 Real-Time Defense Mechanisms in Cybersecurity 34:20 The Role of Tooling in Smart Contract Security 39:04 Human Error vs. Automated Security Tools 41:24 AI's Impact on Social Engineering and Human Error 42:53 Emerging Threats from AI in Cybersecurity 44:17 Teaching Blockchain Security: Common Misconceptions 45:23 Future Directions in Blockchain Security Research   Resources and Links Arthur’s website: https://arthurgervais.com/ Arthur’s Google Scholar: https://scholar.google.ch/citations?hl=en&user=jLr_xi4AAAAJ&view_op=list_works&sortby=pubdate Arthur’s X: https://x.com/HatforceSec Oak Security’s Research: https://research.oaksecurity.io/
