Quantum Computing Threat to Crypto on the Horizon, According to Coinbase Advisory Board

The crypto industry has been cautioned that it cannot afford to wait for the advent of quantum computing, which poses a significant threat to the security of digital currencies. A report commissioned by Coinbase and authored by prominent cryptographers and academics highlights the urgent need for preparation. Although current quantum machines are not powerful enough to crack the cryptography underpinning major networks like Bitcoin and Ethereum, the report stresses that complacency is not an option. The authors warn that a large-scale, fault-tolerant quantum computer will eventually be built, and the uncertainty surrounding the timeline is a major concern. Estimates suggest that this could happen within a few years or a decade, and the U.S. National Institute of Standards and Technology recommends migrating to quantum-resistant cryptography by 2035. The report emphasizes that waiting for the threat to become urgent is not a viable strategy, as transitions across blockchains, wallets, and exchanges could take years to execute safely. Some assets may be more vulnerable than others, and the report outlines multiple transition strategies, including hybrid systems that combine existing cryptography with post-quantum updates. The authors recommend flexible approaches that avoid sacrificing current security or performance while enabling a rapid upgrade later, emphasizing that the time to begin preparing for the quantum computing threat is now.
