Coinbase Advisory Council Report Warns of Imminent Quantum Computing Threat, Urges Early Action from Crypto Industry

On April 22, a 50-page report commissioned by Coinbase highlighted that while current quantum computers are not yet capable of breaking the encryption technologies of networks like Bitcoin and Ethereum, fault-tolerant large-scale quantum computers will eventually be developed, necessitating immediate preparations from the crypto industry. The report was authored by an independent advisory council, which includes cryptographers and scholars such as Dan Boneh from Stanford University, Justin Drake from the Ethereum Foundation, and Sreeram Kannan from Eigen Labs. The report estimates that the timeline for quantum computers to crack current encryption standards ranges from several years to over a decade. The U.S. National Institute of Standards and Technology recommends transitioning to quantum-resistant cryptography by 2035, but the report suggests this timeline may be overly optimistic. Quantum-resistant cryptography already exists and is being standardized, but post-quantum digital signatures could be tens to hundreds of times larger than current signatures, potentially increasing block sizes by up to 38 times and posing challenges such as wallet migration. The Ethereum Foundation has proposed a quantum-resistant digital signature scheme, and Solana is also experimenting with quantum-resistant wallet designs. The report recommends adopting flexible transition strategies, such as hybrid systems, to avoid sacrificing current security while preparing for future upgrades.
