The Quantum Computing Threat: Insights from Naoris Protocol's CEO

David Carvalho, the Founder and CEO of Naoris Protocol, warns that the threat posed by quantum computing is not just a future concern; it is happening now. State actors are preparing to use this technology to breach traditional security systems, potentially putting our financial infrastructure at risk. In an interview, Carvalho shares critical insights on how the blockchain and cryptocurrency sectors must adapt to counter this impending threat.

Key Takeaways

Immediate Threat: Quantum computing is a current threat, with state actors preparing to exploit it.
Regulatory Concerns: The SEC has recognized the potential risks and mentioned Naoris Protocol in relation to post-quantum blockchain technology.
Vulnerability of Blockchains: Traditional blockchain systems are at risk due to quantum computing's ability to break current cryptographic methods.
Legacy Systems: Retrofitting existing banking systems to be quantum-resistant is possible with incremental adaptations.
Harvest-Now-Decrypt-Later Attacks: These attacks are a real threat today, with hostile entities collecting encrypted data for future decryption.
Engagement with Regulators: There are ongoing discussions about the need for quantum-resistant blockchain solutions within regulatory circles.

Quantum computing, which Naoris Protocol CEO talks about

The Quantum Computing Challenge

David Carvalho emphasizes that predicting the emergence of a cryptographically effective quantum computer is fraught with uncertainty. He mentions credible timelines suggesting this could happen within the next decade, while the regulatory focus seems to be on 2028 for enforcing quantum resilience. However, the concern lies not just with the timeline but the lengthy migration process required to secure the entire infrastructure that supports digital trust—this involves complex adjustments to various systems, including Public Key Infrastructure (PKI) and banking frameworks.

Once quantum computers become operational, all digital mechanisms that protect identity, money, and software will be at risk, leading to potential impersonation and fraudulent transactions.

Risks to Blockchain Networks

Blockchains, which commonly rely on the ECDSA or EdDSA algorithms for signature verification, are particularly susceptible to quantum computing threats. Carvalho explains that Shor’s algorithm can easily compromise these systems, risking exposure of private keys and allowing unauthorized access to wallets and validators. Issues like address reuse further heighten this risk, as once a public key is compromised, the associated address becomes a target in a post-quantum scenario.

Adapting Legacy Banking Systems

Regarding legacy banking systems, Carvalho expresses that it is possible to modernize them to incorporate quantum-resilient protocols gradually, utilizing layered, incremental approaches. New post-quantum solutions can operate as additional layers over existing infrastructures, allowing institutions to protect their systems without completely overhauling their operations.

Current Vulnerability to HNDL Attacks

The phenomenon known as Harvest-Now-Decrypt-Later (HNDL) is currently a genuine concern. State actors are accumulating encrypted information—such as wallets and internal communications—while it's still secure, preparing to decrypt it once they have access to quantum computing. Though blockchain data is public, other forms of stored information are valuable targets for these actors.

The Impact of Quantum Computing on Bitcoin and Ethereum

If a quantum computing breakthrough were to occur suddenly (termed "Q-Day"), the repercussions for Bitcoin and Ethereum could be significant. Selective theft might target public keys, potentially leading to disruptions in the blockchain systems, where organized theft and fraudulent transactions could occur. Similarly, banks could face failures in their PKI systems leading to widespread operational challenges.

Collaboration with U.S. Regulators

Carvalho mentions active involvement in discussions with U.S. regulators to address the risks posed by quantum computing. The field of quantum-resistant blockchain technology is gaining attention in regulatory contexts, marking the first mention of blockchain protocols in safeguarding digital assets against quantum threats. This involvement is crucial for ensuring that appropriate strategies are put in place to protect against evolving threats.

The Evolution of Cybersecurity

Decentralized cybersecurity differs fundamentally from traditional validator networks by focusing on validating the environment—devices, software, identities—rather than merely verifying transactions. Carvalho notes that next-generation systems will validate all aspects of digital trust, grounding this validation in post-quantum cryptography and analytics.

Overlooked Trends in Quantum Cryptography

Experts often underestimate the challenges linked to migration to quantum-safe protocols, including developing key management strategies, upgrading hardware security modules, and the complexities in managing parallel systems. The convergence of AI and quantum computing also poses new potential threats, with future AI systems being capable of outpacing human responses.

In conclusion, the transition towards quantum resilience in cryptocurrency and blockchain technologies is imperative, requiring a proactive approach from all stakeholders to mitigate risks associated with this emerging technology.
