While still in its early stages, quantum computing could soon threaten Bitcoin and other proof-of-work systems, as noted by Amit Mehra, a partner at venture capital firm Borderless Capital.
In a discussion with Cointelegraph at Global Blockchain Congress Dubai 2025, Mehra indicated that Borderless Capital is “digging deeply into quantum computing” and examining how various companies are advancing quantum resistance technologies.
Mehra forecasted that quantum computing could take until the end of the decade to fully mature. Nonetheless, he emphasized that the fast-paced evolution of technology is often underestimated:
“Given the recent advancements in chip technology, computational tech, and the capabilities of decentralized computing, it [quantum computing] is undeniably a concern. If not imminent, then certainly in the very near future.”
Quantum computing leverages the principles of quantum physics to process information significantly faster than contemporary machines. Although still emerging, it has the potential to undermine the encryption that secures cryptocurrencies and other sensitive data, prompting developers to create new security standards that can withstand quantum threats.
Charles Edwards, founder of the quantitative Bitcoin and digital asset fund Carpriole, expressed that the urgency of the situation is greater, advocating for the industry to implement solutions before it’s too late.
On Oct. 15, he tweeted, “If Bitcoin doesn’t address quantum concerns in the next year, Gold will continue to outperform it indefinitely.”
“This is an emergency, and we need to identify a solution next year,” he added.

Addressing the quantum challenge
Mehra and Edwards are not alone in their concerns regarding quantum computing.
In July, SUI Research introduced a new cryptographic framework aimed at shielding blockchains from quantum threats—without requiring hard forks, new addresses, or key resets.
However, while the new solution is effective for SUI, Near, Solana, Cosmos, and other blockchain networks, it does not resolve the issues for Bitcoin or Ethereum.
Meanwhile, the US government is reportedly contemplating investments in quantum computing to bolster national security interests.
An October report from Bloomberg stated that the US Department of Commerce may allocate funds to this burgeoning technology in a bid to remain competitive with China.
