Coinbase and the broader crypto industry are rethinking their security foundations because of Quantum computing. Bitcoin, Ethereum and most major blockchain networks rely on encryption that classical computers cannot crack but a new breed of computers threatens to change that.
As a result, Coinbase already formed an advisory board, the Ethereum co-founder Vitalik Buterin is already calling for major upgrades and governments are racing to normalise new cryptography standards.
Quantum computing is a new generation of technology that uses the principles of quantum mechanics to process information at extraordinary speeds. Unlike classical computers, which process data in binary bits, quantum computers use “qubits” that can exist in multiple states simultaneously.
However, this makes them exponentially more powerful for certain types of calculations and experts warn that these advanced calculations could one day include encryptions that can break every single crypto wallet on earth.
How Quantum Computing Threatens Crypto Security
Most modern blockchain networks rely on elliptic-curve cryptography, a system that makes it easy to generate a public key from a private one and they’re virtually impossible to reverse. Normally, classical computers cannot break this encryption in any possible time frame but quantum computers can.
While quantum computing is not currently a threat, it still poses significant risks especially in the next decade and the crypto industry needs to move fast.
Coinbase Moves First
Rather than wait around, Coinbase acted fast. Earlier in the year, Coinbase established an Independent Advisory Board on Quantum Computing and Blockchain, assembled with six of the world-leading minds across cryptography, quantum theory and distributed systems.
Notably, the board includes researchers from Stanford, the Ethereum foundation and the University of Texas at Austin.
More importantly, the board operates independently from Coinbase’s internal teams and its findings will be made publicly available for the entire blockchain ecosystem. CEO Brian Armstrong framed the move simply: “Security is our highest priority at Coinbase. Preparing for future threats, even those many years away, is crucial for our industry.”
Solvable But The Clock is Ticking
Armstrong remains calm about the threat. Speaking at the World Liberty Forum in February 2026, he told CNBC the quantum risk is “a very solvable issue,” adding that Coinbase is already in contact with major blockchains about upgrading to post-quantum cryptography.
Still, the urgency is real. Jameson Lopp, Chief Security Officer at self-custody platform Casa, warns that upgrading Bitcoin alone could take “up to a decade.” Migrating global blockchain systems to new cryptographic standards requires years of planning and coordination. Starting now is not optional.
How Other Blockchain Projects are Responding
Coinbase is not acting alone. The Ethereum Foundation has also made post-quantum security a core strategic priority, with Vitalik Buterin publicly stating that Ethereum should aim to be “cryptographically safe for 100 years.”
Also, Solana developers are actively testing quantum-resistant signatures and Bitcoin participants are debating new architecture upgrades. Governments are also moving, formalising new post-quantum cryptographic standards and putting additional pressure on crypto firms to adapt.
Quantum researcher Anastasia Marchenkova welcomed the board’s structure. “These aren’t just Coinbase people, and they’re not just researchers, they’re also cryptocurrency experts. That’s important, because one of the biggest challenges in post-quantum security is bringing together people who understand quantum computing with people who understand cryptography and real-world systems.”
Why Institutional Investors are Paying Attention
Beyond the technical challenges, there is also a confidence problem. Investor Kevin O’Leary recently warned that quantum fears could deter institutional investors from increasing their Bitcoin exposure and that even the perception of a threat could scare large financial players who are only beginning to enter the market.
That is exactly why Coinbase’s public-facing approach matters. “Each additional person and entity that starts talking about post-quantum security is another signal that people are considering it”, Marchenkova said.
Ultimately, by openly addressing the risk, this proves to banks, pension funds, and asset managers that the industry is ahead of the problem, not running from it. The coming months will reveal just how seriously the industry takes that responsibility.
