Zerotier CEO: Crypto’s Real Quantum Risk Is <a href="https://thelethalcompany.ru/data">Data</a> in Transit, Not Wallet Keys

According to Zerotier CEO Andrew Gault, the biggest threat to cryptocurrency isn’t the possibility of future computers breaking into wallets. Instead, it’s the encrypted transaction data that attackers are collecting right now.

  • Key Takeaways:

  • Zerotier’s Andrew Gault says harvested network data is crypto’s top quantum risk.
  • Ethereum has begun a coordinated post-quantum migration in 2026, while Bitcoin has not.
  • Some estimates put a quantum computer able to break Bitcoin’s encryption as early as 2027.

The Risk Is in the Data Already Moving

The crypto industry’s focus on quantum-proofing wallets may be aimed at the wrong target, according to Andrew Gault, chief executive of networking firm Zerotier. He argues that the most pressing danger is not stored keys but the information flowing between institutions in real time, further adding:

The biggest risk to our financial system isn’t information that’s already been stored – it’s the data being exchanged between banks at this very moment. Hackers are collecting everything – payment details, security confirmations, and digital signatures – as it travels across networks, even if they don’t understand it yet.

Security experts are warning about a tactic called “harvest now, decrypt later.” This means attackers don’t need powerful quantum computers right away to pose a future threat. They can intercept and save encrypted data today, and then unlock it years later when quantum computers become strong enough to break the encryption.

This changes how we think about the threat from quantum computers – it’s not just a problem for the future, but one we’re facing right now as data is being collected. While new encryption methods (post-quantum cryptography) can protect information from future attacks, they don’t help data already collected. Experts like Gault believe this means the risk is already happening, because previously collected data could be decrypted once quantum computers become powerful enough.

Why the Proof Layer Matters

Gault argues that the collected data isn’t simply private; it’s essential. He explains that authentication records—those that verify identities and permissions online—establish ownership, validate transactions, and ultimately determine legal responsibility.

If that layer can eventually be decrypted and forged, the consequences extend well beyond individual wallets. Settlement records, signatures and payment confirmations underpin the trust between banks, exchanges and blockchains. An adversary able to rewrite or impersonate them in the future could call past transactions into question, a systemic risk rather than a series of isolated thefts.

The warning sharpens an uncomfortable contrast because while Ethereum has moved toward a coordinated post-quantum migration, Bitcoin has not adopted a comparable plan. Bitcoin’s transactions are secured by the elliptic curve digital signature algorithm (ECDSA), a scheme that a powerful enough quantum computer could in theory break.

However, timelines are still quite contested as analyst Nic Carter believes that a so-called Q-Day could arrive by 2035, while other estimates are far more aggressive, placing a code-breaking machine as early as 2027. Google’s quantum advances have repeatedly pushed the security debate back into focus, as venture investor Chamath Palihapitiya recently warned that non-state actors could one day target Bitcoin’s holdings as a “honeypot.”

Developers have recently started speaking up more, but most still prefer to adopt new technologies gradually and wait for widely accepted standards, rather than being forced to change. This cautious approach is what Gault’s recent statements seem to question.

Securing Data In Transit

Zerotier is actively involved in advanced network security. They recently released Zerotier Quantum, a platform designed to meet the stringent cryptographic requirements of the U.S. government and standards set by NIST. Because of this, Gault tends to emphasize the importance of securing data while it’s being transmitted – which is exactly what his product does.

Still, the underlying point is hard to dismiss. If adversaries are already banking encrypted traffic for a future payday, then the window to protect it is now, not on Q-Day. For Bitcoin in particular, the question is whether a community that prizes deliberate, consensus-driven change can move fast enough to defend data that is being harvested while the debate continues.
