The looming threat of quantum computing has sparked intense debate within the cryptocurrency community, but a recent report from Galaxy Digital suggests that not all Bitcoin wallets are equally at risk. Will Owens, a research analyst at Galaxy Digital, delves into the specifics of which wallets are vulnerable and what measures are being taken to mitigate the threat.
Understanding the Quantum Threat
In theory, quantum computers could derive private keys from public keys, allowing attackers to impersonate the owner, forge signatures, and steal coins. However, Owens clarifies that the risk is not as widespread as some might believe. “In fact, most wallets are not vulnerable today. Funds are at risk only when public keys are exposed on-chain,” he said.
Exposure Points for Wallets
There are two primary ways wallets can be exposed to quantum threats: wallets whose public keys are already visible on the blockchain, and wallets whose public keys are revealed at the time of spending. This distinction is crucial, as it highlights that not all users are equally at risk.
The Developer Response
Contrary to some public criticism, Owens found that Bitcoin Core developers are actively addressing the quantum threat. “The pace of proposals has accelerated meaningfully since late 2025,” he noted. Proposals such as the soft fork BIP 360 are being actively developed, reviewed, and debated by experienced contributors in the Bitcoin ecosystem.
Community and Governance Challenges
While the developer community is making progress, the decentralized nature of Bitcoin presents a governance challenge. “Bitcoin has no CEO, no board, and no central authority that can mandate a software update,” Owens said. However, he believes that the universal impact of the quantum threat aligns incentives in a way that past disputes over Bitcoin’s economic direction did not. “Every honest participant in the network, from miners to holders to exchanges, has a direct financial interest in the network’s continued security,” he added.
Forward-Looking Insights
For investors, the key takeaway is clear: the quantum threat is real, but it is recognized and being addressed by the people best positioned to tackle it. Owens emphasizes that while the threat is significant, the ecosystem is maturing and preparing for the challenges ahead. “The ecosystem now has a concrete and maturing set of proposals spanning the full problem surface. These proposals are not theoretical. They are being actively developed, reviewed, and debated,” he concluded.
