Who Controls Your Digital Future: Ledger CEO on Digital Sovereignty

Before You Dive In

• AI has reduced the cost of cyber attacks to near zero and accelerated their speed to near-instant, collapsing the old model of security-by-obscurity entirely.
• Pascal argues that software alone can no longer protect digital secrets, and that dedicated secure hardware is the only architecture built to hold the line against what is coming.
• This conversation covers AI-powered cyber threats, cryptographic identity, Bitcoin as a sovereign asset, and what genuine digital ownership looks like in a world where no screen can be trusted.

On this special episode of The Ledger Podcast, Ledger CEO Pascal Gauthier joins CNN journalist Melissa Bell for a fireside chat at VivaTech in Paris, introduced by Publicis Groupe Chairman Maurice Lévy. Pascal makes the case that we are living through an invisible but seismic cyber war, in which AI has handed attackers an unprecedented advantage over defenders. 

Across a wide-ranging conversation, he connects the dots between hardware security, digital identity, Bitcoin sovereignty, and the democratic order, arguing that how we choose to protect ourselves online is nothing less than a question of human freedom.

“The safest place to store value is Bitcoin on a Ledger.” — Pascal Gauthier

The Invisible Nuclear Blast: Why the Cyber War Is Already Here

Pascal opens with a striking vision, comparing the current surge in AI-powered attacks to “a nuclear explosion, but underground.” While everyone feels the vibration in the form of scams, impersonations, and other security breaches, few appreciate the full force of what is already underway. 

His core argument is that AI has fundamentally upended the economics of hacking, as highlighted in a blog by Ledger CTO, Charles Guillemet. Previously, “security by obscurity” worked well enough because the cost of attack was high and the time required was long, giving defenders the advantage. That balance has now reversed. With AI, attack costs have dropped to near zero, and speeds have become near-instant, meaning a hacker in a garage can now move more nimbly than a Fortune 500 company. 

Worse, modern hacking is no longer a lone-wolf pursuit. It is carried out by large, professional organisations, including rogue states. North Korea, Padcal notes, has made attacking cryptocurrency companies a national speciality. 

The bottom line: if the current situation seems bad, it is only a preview of what is coming.

There’s a real blast going on right now.

Look at the statistics, hackers are winning.

As AI becomes more autonomous, the stakes couldn’t be higher. If humans can’t prove who they are, they lose control. Over their assets. Over their identity. Over their decisions.

From Passwords to Hardware: The Only Real Defence

“Everything that is in software is close to impossible to protect.” – Pascal Gauthier

When Melissa Bell asks about the role of architecture in security, Pascal is direct in his reply: in an age of AI-powered software attacks, the only reliable line of defence is dedicated secure hardware; You cannot ask a general-purpose phone or laptop to protect your most sensitive secrets. A device built to do everything cannot fully protect anything. 

Secure hardware, by contrast, is a purpose-built fortress: the chip and pin standard, Pascal proudly notes, is a French invention, and the Secure Element chip at the heart of every Ledger signer is its direct descendant. 

With quantum computing on the horizon, this architectural principle becomes even more urgent. The good news, Pascal says, is that the defence already exists. Agencies like France’s ANSSI are already refusing to certify hardware that does not protect against quantum attacks. Preparation is now, not later.

Because of AI, and soon quantum computing, software alone is impossible to protect. The attack surface is too large. The vectors too fast. The adversaries too capable.

The only real answer is secure hardware.

Digital Identity & the Cryptographic Handshake

One of the conversation’s most thought-provoking threads concerns identity. Pascal argues that until now, individuals have had no verifiable digital existence, alongside physical presence. You cannot prove, in any robust sense, who you are online, and AI has made that problem dramatically worse. A video call can now be deep-faked. A voice can be cloned. The screen, he says, “was never to be trusted, but now, for sure, cannot be trusted.” 

The solution he proposes is the cryptographic handshake: the same mechanism that allows Bitcoin to prove ownership of an asset can allow a person to prove they are who they claim to be. 

“I sign with my Ledger to prove that it’s me, and you do the same. And then we can have a conversation.” — Pascal Gauthier

This framing reorients the signer from a financial instrument into something broader, an anchor for digital identity in a world where nothing on a screen can be taken at face value.

Bitcoin, Sovereignty & Europe’s Strategic Moment

Pascal is candid about Europe’s hesitancy toward Bitcoin, calling it a strategic miscalculation. Where the United States has moved to treat Bitcoin as a sovereign reserve asset, Europe remains largely on the sidelines. He traces this to a broader cultural conservatism around new technology: 

“When you talk about new technology [in Europe], it’s ‘I’m not sure, talk back to me in 10 years.'” — Pascal Gauthier

Security, by contrast, is a topic that focuses minds, because everyone has already felt its consequences. On the question of AI sovereignty, however, he is more optimistic. Reports that the US government had restricted the export of Anthropic’s Fable 5 and Mythos 5 struck him not as a setback but as an opportunity. 

“I think it’s a blessing in disguise. If they’re not sending it to you, you have to build it anyway.” — Pascal Gauthier

France, he argues, holds a rare position: genuine capability across all three sovereign technologies, namely cryptography, AI, and quantum computing. The moment calls for Europe to back that capability at scale through the kind of public-private partnership that the United States has long understood through vehicles like DARPA.

Three technologies are converging, and together they are reshaping the foundations of our digital world: Crypto. AI. Quantum computing.

Each is transformative on its own. They are redefining security, trust, and digital sovereignty.

Citizen First: The Democratic Order & Digital Sovereignty

The conversation’s most philosophical passage arrives when Pascal lays out what he calls “the right democratic order.” He describes a dangerous temptation in the current moment to place the institution above the citizen, to tell people, in effect, “Don’t worry, the state has you.” Though the intention may be protective, the structure it creates produces weak, dependent citizens rather than empowered ones. 

Ledger’s position, he goes on to say, is citizen first: sovereign, responsible, and empowering to the institutions that govern. “This is not anarchy,” he is careful to clarify. “It is the normal democratic order.” 

What Ledger provides is a device on which a person can hold their money, their identity, and their credentials, fully under their own control, making it a technology that allows individuals to participate in democracy as genuine agency rather than as subjects of systems they cannot see or audit. 

“It is of fundamental importance for freedom and democracy,” he concludes, “not just business, not just security.” — Pascal Gauthier

The Role of Profit in a Forever War

Pascal closes by addressing a question Melissa Bell raises about the concentration of world-shaping power in the hands of a few private companies. His answer is characteristically direct: making money is the prerequisite, not the problem. 

“This is not a war for the next six months. This is a forever war.” — Pascal Gauthier

Sustaining the R&D, the talent, and the product roadmap required to stay ahead of adversaries demands a healthy, profitable business. The Ledger CEO is careful to distinguish profit-seeking from the motivation to build, arguing that the most consequential builders are driven by what they want to achieve rather than by money itself. 

What matters in the end, he says, is where the heart is and what the intention is, and on that question, citizens must retain both the right and the means to hold leaders accountable.
