Simply put
- Brian Armstrong, CEO of Coinbase, stated that quantum computing isn’t likely to “destroy blockchain,” referring to the issue as “a very solvable problem.”
- The exchange set up a quantum advisory board last month as Ethereum, Solana, and Bitcoin developers prepare for future shifts in the crypto landscape.
- Armstrong further commented on U.S. market structure discussions, defended Coinbase’s stance on the CLARITY Act draft, and supported the CFTC’s role in regulating prediction markets.
On Wednesday, Coinbase CEO Brian Armstrong emphasized that quantum computing “is not going to destroy blockchain,” labeling concerns as “a very solvable problem” and mentioning that the company is actively collaborating with major networks for future advancements.
In an interview with CNBC at the World Freedom Forum in Mar-a-Lago, he was asked whether fears about quantum technology harming blockchain were accurate. He responded, “No, that’s not true” and reiterated that the problem is manageable.
Armstrong noted Coinbase’s proactive approach, mentioning the formation of a quantum advisory board that stays in regular contact with major blockchains to facilitate upgrades for a post-quantum environment.
“We’ll keep working on this issue, and I genuinely believe it can be resolved,” he added.
Quantum computing and cryptography
His comments coincide with the shift of quantum computing from a distant theoretical concern to a practical engineering challenge for blockchain developers.
While current quantum machines can’t break widely used public-key cryptography, experts warn that transitioning financial systems and decentralized networks to a new standard could take years.
Coinbase established an independent advisory board last month that includes distinguished figures like University of Texas professor Scott Aaronson and Ethereum Foundation researcher Justin Drake. The group is tasked with assessing quantum-related risks and formulating a transition strategy.
Pranab Agarwal, an independent director of India’s first listed Bitcoin treasury company JetKing Infotrain, explained, “The primary concern of quantum computing for Bitcoin is the potential to break SHA-256 encryption.” He also pointed out that the timeline for a sufficient quantum model is uncertain, while upgrading encryption remains much more feasible.
Agarwal highlighted that industry insiders believe there’s ample time to enhance encryption standards across major networks, stating, “There is plenty of time” for projects like Bitcoin and Ethereum.
Recently, the Ethereum Foundation prioritized post-quantum security, pushing the industry toward better preparation.
Vitalik Buterin, an Ethereum co-founder, urged developers to adopt quantum-proof cryptography without delays to ensure long-term security against possible vulnerabilities.
Additionally, the Solana Foundation has begun testing quantum-resistant digital signatures, while Bitcoin developers are progressing on proposals aimed at minimizing key exposure to quantum threats.
Coinbase and the CLARITY method
In the same interview, Armstrong backed the Commodity Futures Trading Commission’s role in overseeing event contracts and touched on ongoing discussions about U.S. market structure legislation, stablecoin compensation, and prediction markets.
He referenced Coinbase’s opposition to an earlier draft of the market structure bill, known as the CLARITY Act, mentioning that the company had “some issues” particularly concerning the handling of stablecoin rewards.
Armstrong rejected claims that Coinbase was “blocking” the bill, asserting that their concerns would prompt lawmakers “back to the table” and expressed optimism that a compromise bill could still progress and make its way to the president in the coming months.
