Charles Guillemet and Mo El-Sayed on AI making security flaws cheap to find

AI Made Security Flaws Cheap to Find. What Now?

Security used to depend on flaws being expensive to find. AI made them cheap. High-severity vulnerabilities flagged in 2026 are already six times the previous four-year average. Ledger CTO Charles Guillemet sits down with Mo El-Sayed, Head of Brand Development, to discuss what that does to the threat model, why secure hardware holds where connected software folds, and the ethics of finding bugs at machine speed.

One Year of Ledger N3XT

A year ago, we launched Ledger N3XT, our education program for university blockchain clubs. Conferences, workshops, hackathons, and a research competition later, students across dozens of campuses built communities around it. From the Texas Squad at UT Austin to clubs at EPFL, Berkeley, and Yale, students got funding, devices, stage time on Ledger Academy, and access to our CTO. The next generation is the one that will run this space, and our job is to make sure they’re ready.

Ledger CTO Charles Guillemet on Bitcoin's post-quantum migration problem

Ledger CTO on Bitcoin’s Post-Quantum Migration Problem

Bitcoin does not have a quantum computer problem today. It has a migration problem, and migrations take years to get right. Ledger CTO Charles Guillemet analyzes SHRINCS, the first Bitcoin-specific post-quantum proposal to make a serious end-to-end trade-off. The migration comes down to three questions: which scheme Bitcoin should support, what that scheme does to the protocol and wallet ecosystem, and what happens to coins that have never moved. Most public debate is still on the easiest of the three.
