Coinbase CEO Brian Armstrong characterized quantum computing as a manageable engineering challenge rather than an existential threat to blockchain technology.
The exchange recently established a Quantum Computing Advisory Committee featuring experts like Scott Aaronson and Dan Boneh to guide cryptographic migrations.
Industry leaders, including Vitalik Buterin, are accelerating post-quantum cryptography (PQC) research to protect networks from future decryption risks.
Coinbase CEO Brian Armstrong has downplayed growing concerns that quantum computing could dismantle the cryptographic foundations of the digital asset industry. Speaking in a recent interview with CNBC at the World Liberty Forum, Armstrong argued that the perceived “quantum crisis” is a solvable engineering problem that the industry is already proactively addressing through long-term technical roadmaps and strategic coordination.
The executive revealed that Coinbase has taken a “front-footed” stance by forming a dedicated Quantum Computing Advisory Committee. This group includes prominent figures like University of Texas professor Scott Aaronson, Stanford cryptographer Dan Boneh, and Ethereum Foundation researcher Justin Drake. The committee is tasked with publishing research and outlining migration pathways for blockchains to transition toward post-quantum cryptography (PQC) standards before cryptographically relevant quantum machines become a reality.
“We’re in regular contact with the major blockchains about a path to upgrade to a post-quantum cryptography world,” Armstrong stated. He emphasized that the industry has ample time to implement these upgrades, noting that while current quantum hardware is advancing, it remains years away from being able to crack widely used public-key encryption like ECDSA used by Bitcoin and Ethereum.
While Armstrong expressed confidence, the broader community remains divided on the timeline. Some researchers have suggested that the window for migration could be as short as five to seven years, particularly as hardware breakthroughs accelerate. The Ethereum Foundation has already elevated post-quantum security to a top strategic priority, and Bitcoin developers are exploring foundational proposals like BIP-360 to enhance long-term resilience.
However, the transition is not without friction. Critics like investor Kevin O’Leary have warned that quantum-related uncertainty could deter institutional capital from entering the space. Furthermore, security experts note that inactive or lost wallets may remain permanently vulnerable, as they cannot be manually migrated to new, quantum-resistant address formats by their owners.
Despite these hurdles, Armstrong remains optimistic that the transition will be a natural evolution of the technology. “Security is our highest priority,” Armstrong added via a post on X. “Preparing for future threats, even those many years away, is crucial for our industry.”
