- Coinbase CEO Brian Armstrong dismissed fears that quantum computing will destroy blockchain technology, calling it “a very solvable issue.”
- The exchange has formed a quantum advisory board, and networks like Ethereum, Solana, and Bitcoin are actively preparing for the cryptographic transition.
- Armstrong also discussed U.S. market-structure talks, defending Coinbase‘s stance on the CLARITY Act draft and supporting CFTC oversight of prediction markets.
At the World Liberty Forum in Mar-a-Lago on Wednesday, Coinbase CEO Brian Armstrong spoke with CNBC and confidently addressed the threat of quantum computing to cryptocurrency. Armstrong directly countered the idea that quantum advances would cripple blockchains, stating, “No, that’s not true.”
He emphasized that Coinbase is proactively tackling the challenge through a dedicated quantum advisory council. The company is in regular contact with major blockchain developers to plan a path toward post-quantum cryptography. Consequently, a transition is being viewed as a manageable engineering hurdle rather than an existential crisis.
Meanwhile, preparation across the industry is accelerating as the risk evolves from theoretical to practical. The Ethereum Foundation has elevated quantum security to a top priority, following co-founder Vitalik Buterin’s urging for proactive upgrades. Simultaneously, the Solana Foundation has begun testing quantum-resistant signatures, and Bitcoin developers are advancing proposals like BIP 360.
Armstrong also addressed legislative developments during his interview, specifically clarifying Coinbase‘s position on the CLARITY Act draft. He stated the company had issues with the bill’s treatment of stablecoin rewards but pushed back on claims it blocked the legislation. Instead, he expressed optimism that a compromise could reach the President’s desk soon.
