Coinbase CEO Brian Armstrong stated that quantum computing will not "break the blockchain," characterizing the concern as a "very solvable issue." He confirmed that Coinbase is actively working with major blockchain networks to prepare for future cryptographic advancements.
Armstrong highlighted Coinbase's proactive approach, including the formation of a quantum advisory council. The company is in regular communication with leading blockchains regarding the transition to post-quantum cryptography.
The comments arrive as quantum computing moves from a theoretical risk to a practical consideration for blockchain developers. While current quantum machines are not yet capable of breaking widely used public-key cryptography, experts warn that upgrading global financial systems could take years.
Coinbase recently established an independent advisory board composed of leading experts in quantum computing and cryptography to assess risks and outline migration strategies.
Across the industry, preparation is accelerating. The Ethereum Foundation has prioritized post-quantum security, and Vitalik Buterin has urged developers to adopt quantum-resistant cryptography promptly. Solana has begun testing quantum-resistant digital signatures, while Bitcoin developers are advancing proposals to mitigate quantum-exposed key paths.
Armstrong also addressed U.S. market-structure legislation, defending Coinbase's engagement on the CLARITY Act draft and supporting the Commodity Futures Trading Commission's authority over prediction markets.
