Coinbase Advisory Board Warns of Bitcoin’s Quantum Risk: No Consensus Yet Within the Community—Quantum-Resistant Migration Preparations Should Begin Immediately
A cryptography expert advisory committee led by Coinbase released a report stating that Bitcoin should immediately begin preparing for potential quantum computing attacks. However, the committee did not take a clear stance on whether to freeze the millions of bitcoins potentially vulnerable to quantum-computing theft in the future. The committee includes several leading experts, such as Justin Drake, a researcher at the Ethereum Foundation. They argue that the current debate is not about *how* to introduce quantum-resistant signature schemes, but rather *how to handle* bitcoins held in long-dormant addresses that fail to migrate. One camp advocates setting a final deadline after which Bitcoin’s existing ECDSA and Schnorr signature schemes would no longer be supported, and unmigrated funds would be frozen—thereby preventing future quantum attackers from seizing large amounts of BTC and destabilizing markets. The other camp contends that freezing funds would effectively amount to asset confiscation, violating Bitcoin’s core principles of immutability and full user control over assets—and could set a precedent for future regulatory-driven freezes. The Coinbase advisory committee notes that these approaches are not mutually exclusive and could be combined. Yet it declines to state a position on whether “legacy BTC” should be frozen, asserting that the ultimate decision rests with Bitcoin’s community governance. It emphasizes two key points: first, technical development of quantum-resistant signature migration must begin immediately—not wait for governance debates to conclude; second, users must receive clear, timely risk communication to prevent prolonged uncertainty from harming the Bitcoin ecosystem.
Coinbase Advisory Committee Report Warns Quantum Computing Threat is Approaching, Crypto Industry Needs to Develop Countermeasures Early
Odaily News A 50-page report commissioned by Coinbase indicates that although current quantum computers are not yet capable of cracking the encryption technologies of networks like Bitcoin and Ethereum, fault-tolerant large-scale quantum computers will eventually be built, and the crypto industry must begin preparations now. The report was authored by an independent advisory committee, including cryptographers and scholars such as Dan Boneh from Stanford University, Justin Drake from the Ethereum Foundation, and Sreeram Kannan from Eigen Labs.The report states that estimates for the time it would take quantum computers to break current encryption standards range from several years to over a decade. The U.S. National Institute of Standards and Technology recommends migrating to post-quantum cryptography by 2035, but the report suggests this timeline may be optimistic. Post-quantum cryptography already exists and is undergoing standardization, but post-quantum digital signatures can be tens to hundreds of times larger than existing signatures, potentially increasing block sizes by up to 38 times and introducing challenges such as wallet migration. The Ethereum Foundation has proposed a post-quantum digital signature scheme, and projects like Solana are also experimenting with post-quantum wallet designs. The report recommends adopting flexible transition strategies, such as hybrid systems, to prepare for future upgrades without compromising current security.
