Justus Hanna on AI Bug Hunting (opens the original)
Read excerpt
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 b
Security at Arbitrum with Lorenzo Sicilia (opens the original)
Read excerpt
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 ha
Robert de Groot and Web3 Privacy Now (opens the original)
Read excerpt
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.

Privacy and Institutional Use Cases with Emanuele Francioni (opens the original)
Read excerpt
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
Antonio Viggiano on how Monad is Using AI for Security (opens the original)
Read excerpt
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
