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.
